The new girl

My name is William Wilkins, and at the age of 15 I had an experience that wasn't just "out in left field", but clear out of the ballpark.

Like most guys about that age, I was stuck with the trials and tribulations of puberty. Unlike most guys, I had the benefit of having grown up with a sister (Eva, which I shortened even further to just "Eve", just a bit more than one year older than me) that I got along with pretty well. Not that we were best buddies, or anything, it was just that our folks hadn't tolerated any kind of fighting or arguments between us as we grew up; as a result, we were a lot more tolerant of each other's foibles. Not only did we play a lot of "show me yours and I'll show you mine", but even got to be comfortable with playing "Doctor" to a degree that I doubt our folks would have approved of. That attitude continued even after each of us started puberty, so that seeing each other only in our underwear or half-nude (or completely so when I could manage it) was no big deal of either of us; it wasn't that each of us didn't have other friends, but simply that we'd grown up that comfortable with each other. Since there were hardly any kids our ages in the immediate neighborhood, that was a good thing.

Our relationship was such that neither of us ever said anything (even to each other) about the small holes that developed that gave each of us a viewport from our respective closets into the others bedroom. I got plenty of chances to see how Eva's physical development compared to that of her friends during sleepovers, and even learned how girls masturbate; I don't doubt that Eva had much the same experiences.

That was how things worked in our house right up until a new family moved into the neighborhood in the middle of the Spring semester at school, of all things.

Naturally enough, what really got my attention about them was that there was only one kid: an attractive girl about my age. She wasn't as physically developed as my sister, but still clearly female; she had long, glossy black hair, trim legs, an ass that I immediately fell in love with, and a pretty face with slightly full lips and grey eyes. It didn't take long to learn that her name was Charlene Johnston, and that she was just a few months younger than my sister.

Eva and I were both looking forward to getting to know her, but we saw precious little of her outside of school. After several school days had passed, Sis told me that Charlene didn't seem to have been assigned to one of the mandatory physical ed classes — nobody that Sis knew had her during their period. That made Charlene something of a mystery, but since she remained aloof from everyone pretty much all the time, there wasn't a whole lot more we could learn about her, other than she got damn good grades in all her classes.

It wasn't until several weeks after school had let out that Sis finally got the chance to meet Charlene through the simple expedient of simply walking up to their door, introducing herself, and asking if Charlene would like to come over. Sis later told me that she could see that Charlene wasn't exactly thrilled at the invitation, but didn't have a polite way of declining.

The two of them didn't spend much more than a couple of hours together at first, but as the rest of the summer passed, the frequency and duration of their time together gradually increased. That continued after school started again, as well; Charlene gradually got somewhat friendlier with the other girls at school, but Eva was by far her closest friend. From the amount of time Charlene spent at our house, she and I also got to know each other better and get comfortable with each other. Sis informed me that Charlene and her parents had moved from several states away during the school year because of some unspecified event that happened at her previous school. Both of us wondered what possibly could have happened, but couldn't figure out what it might have been.

By the time it got close to Christmas, Sis and Charlene had become pretty good friends. Along the way, Eva's repeated invitations for a sleepover were declined — but each time it was with less enthusiasm, according to Sis. Shortly after New Years, Charlene agreed… but that she (Charlene) would have to talk to Sis first, and that Sis would have to promise to keep what she (Charlene) had to say as a Top Secret to never, ever be told to anyone else under any circumstances. The sole exception Charlene was willing to grant was for Sis to tell me, provided I was willing (and able, in Eva's opinion) to maintain the same degree of confidentiality.

Needless to say, both of us were wondering what the hell Charlene could have to say that even might call for that kind of demand for secrecy.

It was a couple of days before the two of them sequestered themselves in Eva's bedroom; I don't think it was any coincidence that some of Eva's stuff not only blocked the peephole I had into her room, but she had her radio turned up higher than usual so I couldn't hear anything, either.

The next evening, Sis came into my room after supper and sat on my bed while I was doing my homework. When I got to a stopping point and turned my attention to her, she pointedly told me "Billy, you know Charlene and I talked yesterday after school. What she told me surprised the Hell out of me, and I've got to talk to somebody about it. What she said… it's really, really important that you don't say anything about it to anyone else. That means nobody, not even Mom and Dad; and not now or ever. I know you'll want to, 'cause I sure as hell do, but you can't — not even a little bit. It's not something that you absolutely have to know, so if you don't think that you can keep it to yourself completely and forever, tell me now. Until I have your word on that, I can't break my promise to Charlene. All I can tell you that it's bigger and more important that the stuff we did together when we were kids."

From the way she was talking, I knew she meant all the times we'd looked at (and had our hands on) each other's bodies when we were younger. She wasn't one to exaggerate things, so if she said that whatever it was was bigger than that and had to explicitly tell me how private I had to keep things, I knew I had to seriously think it over before giving her an answer. I did just that for a couple of minutes before answering "Okay, Eve. You've told me how serious it is, and how important it is that I don't tell anybody else. I'm not sure what could be that big, but you have my promise: whatever it is you want to talk to me about, nobody will ever hear about it from me."

Even then, Eva looked into my face intently for several seconds before deciding that not only was I as serious as she was, but telling the truth about keeping whatever Charlene's secret was.

As she took a deep breath in preparation, I couldn't help but wonder what the hell it would be… and was completely unprepared to hear "Charlene is a hermaphrodite."

From the way she said it, I knew I was supposed to be shocked, but I really didn't know what she was telling me. Seeing the look of puzzlement I must have had on my face, Eva explained "Charlene has both girl and boy parts."

Unfortunately, I said the first thing that came to mind: "Of course she does. Everybody has the same parts. Hearts, lungs, kidneys — all that stuff."

Showing her exasperation, she acidly told me "Not that stuff, you dummy. I'm telling you she's got girl and boy sex parts. She has a vagina like a girl, but she's also got a penis, like a guy."

As should be expected, I spent a lot of seconds trying to get my mind around that idea — and only achieved minimal success. Thankfully, our folks had taken whatever chances they could to help us learn about new and different stuff — we made a family trip to Mexico one time, and went with them on a cruise ship in the Carribean, for example, so we'd learn about different cultures; on top of that, they took the time to explain to us about different kinds of handicaps we saw. So the problem I was having wasn't that Charlene was physically different, but how. I mean, I could kinda-sorta visualize that it was physically possible, but I just couldn't take the additional step of imagining it actually happening. All I could do, finally, was stammer "What… how…really?"

"Yeah, really" was the answer I got. Eva went on to say "She didn't actually take her clothes off to show me, but she did lift her dress up so I could see that there was an extra bulge in her panties. She said that she's mostly female, which is why she has tits and everything like a girl, but she also has a penis. She explained it all to me and what happened was that while she was still being made inside her mom, something went wrong; instead of growing all girl stuff like she should have, things got confused and a penis was started, instead. That's about all that's really different about her — I mean, she doesn't have testicles or make semen like a guy; she said that it's more like she has a really big clitoris, is all.

She's always felt like a girl and acted like one, it's just that being different the way she is, she's never been comfortable about getting too close or personal with other girls. The only reason she told me about it, she said, was that she's just so tired of being alone all the time and not being able to do all the stuff she hears about — like going on a sleepover and things like that."

Taking a deep breath, she continued "She also told me what happened that made them move here. She was exempted from gym classes at her other school, too, but one of the student aides in the offices got into her school records and found out why. After that, everybody in school knew about it, and they even had to fire an employee over it… but it was too late for her, of course. All the other kids were giving her such a hard time that her dad got a transfer from the company he worked for so they could move here. That's why she hasn't wanted to have much to do with the kids at school: she isn't stuck-up or a snob or anything, she's just been shy and scared. It's really taken a lot for her to learn to relax after that, and start trying to make friends. She told me that she really had to work herself up to telling me all that stuff about herself so that she could start getting out and doing things. She had friends and everything, before, but it wasn't like normal because of how she is — from the way she talked, I could tell that she missed being able to do so much of the kinds of things that WE got to do growing up."

After she finished, Eva and I both sat there, trying it imagine what life must have been like for Charlene as a kid. Several minutes went by before Eva told me "Anyway, now you know why she's been so slow about being friends and doing stuff with me. I know it's going to be hard for you, 'cause it will be for me, too, but don't stare at her or do anything to make her feel bad or embarrassed, Billy!

This is going to be a really big deal for her, and you know she's taking a huge chance telling me about herself that way and then me telling you… so don't mess this up for her. If you do, I promise you that I will make you seriously regret it!"

I was a little hurt by Sis' warning, and I think she could see it because her expression softened a bit when I answered "I won't. I know I'm kind of a dummy sometimes, and I have to get used to the idea, but I'm not gonna be jerk or anything." Mom and Dad had taught us pretty well that it was okay to notice that someone was different, but to be polite about it.

With that assurance from me, Sis gently told me "Well, when she spends the night, maybe you'll get the chance to learn something that'll make it easier for you to get used to it" before standing up and leaving my room.

It wasn't until after she was gone that I realized I could use the peephole from my closet to her room to see for myself how Charlene was different. From the time she came over until then, though, I'd just have to make sure to keep myself under control.

The following Friday night was to be the main event. I could tell that Eva was nervous when she got home from school, but when Charlene showed up to join us for supper, she'd pulled herself together again. All I had to do was act the way I usually did by staying away from the two of them for the most part. The little bit of conversation I had with Charlene during supper was as brief and casual as any other time she'd been over. I'll confess to trying to check her out a couple of times when she wasn't looking, but otherwise avoided causing any embarrassment for her — which earned me a relieved and pleased smile from Sis when all of us were done eating. I don't know if Mom and Dad had heard anything from Charlene's parents; if so, they did a fine job of hiding it.

Charlene and Sis went back to her room almost immediately after supper; I hung around and watched TV for a little while to continue my (pretend) indifference to Charlenes presence in the house. It was an hour and a half before I finally made my way back to my room; as soon as I'd closed the door, I was in my closet and looking into Eva's room. To my disappointment, the two of them were fully dressed and sitting on the bed in animated conversation. From the (very) little I could hear, it was about the usual girl stuff that I'd heard Eva talk to her other friends about. Still, it was getting late in the evening and I stayed where I was in anticipation of the show that I just knew had to be coming.

It was after Mom and Dad went to bed (wishing all of us a good night through our closed doors) that things changed in Sis' room.

After Mom and Dad had plenty of time to fall asleep, I watched as Eva gestured and said something to Charlene. It took a few seconds for me to figure out that she was suggesting the two of them go ahead and get ready for bed — and you can bet I had every intention of staying right where I was for that little event!

With my eye glued to the peephole and holding my breath, I watched as Eva was the first to move by removing her blouse; as she reached behind her back for her bra fastener, Charlene gave in and began removing her own clothes — starting with her blouse, just as Sis had. When she slipped it off, I was delighted to see that her choice in undergarments was appreciably more adventurous than Eva's: it was a frilly pale yellow thing with lace edges that barely covered her nipples. Reaching between the cups, she unhooked it and let it slide down her arms and land on the floor behind her. That left both of them standing there topless, generally facing each other and angled so that it was easy for me to compare the two sets of young mammaries. Eva's generally conical B-cup breasts were more-or-less familiar to me, sporting quarter-diameter dark pink areolas that looked like they were capped with small pebbles of pink bubblegum. Charlene's breasts were more rounded, and were actually larger than they'd seemed; at the peak of each was a pale dime-sized areola that sported a nipple that had to be half an inch long.

Looking at them, I could only dream of what I'd like to do with them.

After several seconds of back-and-forth, it was up to Sis to get things going again by slipping her thumbs under the waistband of the slacks she was wearing; a little more negotiation, and Charlene followed suit with the skirt she had on. I could see as Eva counted down before each pushed her respective garment off her waist, over her hips, and down her legs. When they stood up, the additional bulge in Charlene's panties stood in stark contrast to the smooth arc formed by Sis' mons. Several times, Charlene acted like she wanted to move her arms so that she could use her hands to cover her pelvis, but she never quite finished the movements. Instead, she just stood there as she and Sis looked each other over for a minute or so.

I heard Eva say something, and knew it was a question by the way Charlene slowly nodded her head. I learned what it must have been when Eva began to slip her panties off as Charlene watched. It didn't take long to rid herself of the brief panties she'd had on, and casually toss them onto the bed where her other clothes were. Even peering at the two of them through a tiny hole in the wall, I could see how nervous and apprehensive Charlene was; Eva just stood there calmly, and after several seconds I clearly heard her say "I know you're scared, Charlene, but it's okay… really. You told me about yourself, and I'm okay with it — honest. I'm not going to push you or anything; I'm just going to stand here until you decide that you're ready to go on. I like you, and I want to be your friend — it's up to you to decide if you want to let that happen."

A full minute passed, and after several false starts, Charlene slowly moved her hands to the waistband of the plain white cotton panties she had on and eased her thumbs under the waistband. Many more seconds went by before she began to gradually ease them down ever so slowly. It was easy to see the conflicting emotions on her face as the tops of her panties slowly moved lower and lower on her body, eventually reaching the point where the top of her dark black pubic thatch began to be revealed. When tops had reached the point that they were just above the beginning of her added bulge, she must have found a reservoir of courage, because she suddenly bent over and pushed them all the way down to her ankles and stepped out of them. Once she stood up again, it was easy to see what had caused it: what could only be described as a male penis.

Seeing it sticking out that way while there were a pair of perfectly lovely breasts showing farther up was something of a shock to me, at first. But once I got past that, it didn't seem like all that much of a big deal. I was watching and listening for what Eva's reaction would be, and watched her check it out for a few seconds before looking into Charlenes face and saying "Yeah, it looks like a penis, all right.

But it's not even a couple of inches, and not very big around… no, it's not going to bother me."

Charlene's relief was as obvious as it could be as she said "I'm so glad to hear that! I was so afraid that once you saw it, you'd freak out or something."

Eva laughed briefly, and told her "No, I wouldn't freak out. Our folks have been real good about making sure that Billy and I learn and understand that there's more going on out in the world than just what happens around here, so we have open minds about stuff. Dad tells us that an open mind can hold things that a closed one can't make room for. So, yeah, you being a hermaphrodite is definitely something new that I've never thought about before, but as far as I — or even Billy, probably — are concerned, it's just something different, not bad or weird or anything. If you're okay with showing me, I guess it wouldn't bother you too much if I had some questions? Like I said, this is new and different for me…"

Charlene didn't hesitate in the slightest to answer "No, I don't mind. Actually, it would be kind of a relief for me to be able to explain it to someone. Um… I, uh, I won't have any problem if you want to look… you know, closer… if, um, it would be okay if I, um, looked at you. I… I've never had the chance to see what a regular girl looks like — you know, there…"

"Shucks, I don't mind. After all the gym classes I've had, having another girl looking at me between my legs isn't any big deal. You want to look first?", Eva asked, smiling.

"No, you first. I just want to see, which won't take long. You're going to see and have a bunch of questions and everything, so let's get that part out of the way."

To my and Sis' surprise (and my delight), Charlene calmly turned and sat down on the edge of Sis' bed before pulling her legs up and spreading them — giving Sis and me a clear and unobstructed view between her thighs. Just as Sis had said, Charlene also had a vagina; I didn't have any trouble not only making out where it was, but that the inner lips she had weren't all that different from Eva's (or any of her friends that I'd seen). It took only a few moments for Sis to take a seat on the floor (where she wasn't blocking my view, thankfully) and lean forward.

With both of them fairly low like that, they were in a good position for me to hear what they had to say and I got quite an education for nearly an hour. I learned that it wasn't all that rare for babies to have some degree of hermaphroditism, that Charlene's penis sometimes got harder but never fully erect, that she had periods like any other girl, and she most certainly experienced the same physical desires, among other things. As part of the Q amp;A, Charlene wasn't the least bit reluctant about reaching between her thighs and manipulating things to clarify or emphasize the things she was saying; she even went so far as to tell Eva that it was okay if she wanted to touch and move things. After a little initial trepidation, Sis did take advantage of the opportunity she was being given.

When they were done, Eva readily matched the position Charlene had been in — giving me the best view I'd ever gotten (at least, since she started puberty) of the area between her thighs. Eva had opted to sit on the "near" side of Charlene, so I didn't have any trouble making out the cleft of her sex amid the dark blond curls of her pubic area. At the top, the hood over her clitoris was barely visible; her labia were thin and the area between them appeared to already be glistening faintly. It took only a few moments for Charlene to get herself seated on the floor between Sis' feet. Again, their positions ensured that I had a good view of what was happening as Charlene initially contented herself with simply leaning forward and just looking at Sis. After just a couple of minutes, I heard Eva tell Charlene "Go ahead and touch me, if you want to — it's only fair."

With that, Charlene slowly moved her hand between Sis' legs… and after a brief hesitation, made contact with Eva's mons. The sight as Charlene's slender fingers tenderly probed and manipulated Eva's womanhood soon had me sporting what I was sure was the biggest and hardest erection I'd ever had; it was only a couple of seconds effort to free it from my pants and underwear and begin stroking myself as I kept my eyes locked on the sight before me. Charlene whispered something I couldn't hear to Sis and got a nod in reply; it was when I saw the ends of her fingers gently ease toward Evas opening that I couldn't hold back any longer, and sprayed the wall of my closet with what felt like quarts of my cum.

Even as that was happening, however, I had my eye glued to my viewport into Evas room, and was able to see that even though Charlene barely had the first digit of a single finger through the portal to Evas sex, it was enough to have Sis' breasts visibly hard and tight, and her nipples erect — as well as thoroughly anointing the invading digit with her female essence.

It wasn't just Eva that was feeling the effects of Charlene's manipulations: it was plain as could be (even from where I sat) that Charlenes breasts were tight and sporting hard and erect nipples, too. With her sitting at an angle to me, I couldn't see what was going on with her extra appendage, but the fact that Sis made several lengthy looks that direction suggested pretty strongly to me that something was happening with it.

Still, as Charlene had said, it didn't take her anywhere near as long to learn what she wanted to know about normal female genitalia as it had for Eva to learn about hers; it couldn't have taken as long as fifteen minutes before Charlene slowly withdrew her hand from between Evas thighs and sat back again. When she did, the two of them simply sat there looking into each others eyes and faces…

Charlene sitting on her feet on the floor while Sis remained on her bed, legs spread wide and revealing the glistening opening between her thighs. It was when Charlene finally stood up a minute later that I saw that the small penis protruding from the dark wedge of her pubic hair had changed. Though it hadn't gotten noticeably longer or thicker, there was no denying that it had gotten stiffer and was protruding nearly horizontally from her pelvis instead of pointing at the floor as it had been before.

Eva slowly brought her legs together and her feet to the floor, then stood up to face Charlene. I could see her look down to the protrusion of Charlenes cock for a few seconds before looking into Charlenes face. Several seconds of quiet were broken when Charlene spoke, her tone of embarrassment obvious as she softly said "I… I'm sorry about that, but it's not something I've ever been able to do anything about. I've asked the specialist that I see about it, and he says it's just a part of who I am, and that nothing he can do will change it: if I get, you know, excited, then the boy part of me will react along with the girl part. I… I've kind of figured out by myself that because my body is different enough to have a penis, there's some little part of me deep down inside that just can't help trying to respond to some things. I mean, I don't do it on purpose, or anything…"

A couple of seconds went by, and Eva told her "It's okay, I guess. I mean, I could tell that you weren't doing it 'cause you wanted to. I knew things were going to be different with you being a hermaphrodite and everything, and I guess that's just part of it. Besides, it's not like you tried to do something, or anything. I don't figure that'll be the only time it happens, so I'll just learn to get used to it, is all."

Immensely relieved, Charlene told her "I… I'm glad you understand, and you're willing to be so cool about all this. I've never had a real friend that I could do stuff with like you before, and I've missed out on SO much stuff because of it."

Smiling, Eva told her "Well, you don't have to miss out on it any more unless you want to", and the two of them quickly hugged each other. Charlene's head was toward me, and I could see how happy and pleased she was about how Sis was acting about the whole thing.

When they finally released each other, it was so they could get into their respective nightgowns. I watched a little longer to see if anything else was going to happen, but all they did was break out some magazines and start comparing what they thought of the guys in them.

After using my shirt to clean the semen running down the wall in my closet, I undressed down to my underwear and went to bed. Laying there in the dark, I stayed awake for quite a while as I thought not just about how lonely and isolated Charlene must have felt growing up, but what I thought and felt about her physical difference, too. It took a little while, but I finally got things settled in my mind: first was that it wasn't like she chose to be born that way; it was more like Mother Nature played a particularly cruel practical joke on her. Second was that I'd decided she was a nice, smart person with a really pleasant personality and keen sense of humor before finding out that there was anything

physically different about her… so there really wasn't any reason to change how I thought about her.

Finally, she was pretty good-looking if I could put her difference out of my mind — which gave me pause to think about her condition and what I really thought about that. After a lot of back-and-forth and wrestling with the idea in my mind, I finally decided that it really shouldn't matter; as she'd said, it wasn't something she had any control over, and she certainly seemed female enough in every other way. Not figuring that there was any chance in hell that I was ever going to do anything else with her, there was nothing for me to do but just treat her like just another one of my sisters girl friends.

When the two of them came dragging out of Evas bedroom late the next morning, they acted as though they'd been best friends forever instead of having known each other not even a year. They were sharing private jokes with each other, and judging from the way they'd share just a brief look before smiling or laughing, had gotten onto the same "wavelength", too. I just responded to them the same way I did any other time one of Evas friends spent the night: ignoring them as much as possible, and returning whatever comments they directed my way in kind.

After Charlene went home shortly after lunch, Eva stopped by my room (where I was putting together a plastic model of an airplane) and asked me what I thought. I didn't have a problem telling her "I guess I did learn a few things, after all. Yeah, Charlene's different — but not in any way that's really important.

I'm cool about it, and everything."

Pleased (though faintly blushing, I noticed), Sis told me "I'm glad to hear that, Billy. She really is a good person, and this is the first time she's really been able to break out of the shell she built around herself. I'd hate to see anything happen to mess it up for her."

"Well, if anything like that does happen, it won't be because of me", I assured her.

She just smiled, and left.

After that night, Eva and Charlene became even better friends. Sis got Charlene to participate more in the things she and her friends did in and out of school, though never to the extent of getting involved in anything that risked revealing Charlenes condition. The only one Charlene was really willing and comfortable about seeing her less than fully dressed was Eva, and it didn't take long before the two of them were spending a lot of nights together, either at our place or Charlenes. Mom and Dad got concerned about it, called Charlenes folks, and learned that they were more than delighted to have Sis at their house as often as she was, and had been concerned that Charlene was visiting us too often. It didn't take long for all of them to reach the decision that since neither side was feeling "put-upon" (and would say so if things changed), there wasn't any reason not to let the two girls continue.

I certainly didn't mind, since it meant that I'd almost certainly get chances to check out Charlenes nude body, as well as Evas.

That proved to be the case, and it didn't take long for me to accept the presence of a small finger of flesh protruding from Charlene's pelvis — regardles of what state that protrusion happened to be in.

As was to be expected, there came the time that I happened (not by accident, either) to run across Charlene in the hallway as she was making a (braless) bathroom visit one night. I didn't make any pretense of not looking her over before saying "Nice boobs, Charlene!" and continuing on my way. I learned the next day that I'd responded perfectly: I'd obviously seen the over-full condition of her panties, and then calmly proceeded to ignore it in favor of complimenting Charlene on her breasts.

Though Charlene tried to be more careful about having her bra on after that, it didn't take long for her to stop worrying about me seeing her in her panties.

My comment to Charlene also had the effect of making it okay for her and I to begin interacting more than we had before. It wasn't that she and I ever hung out together or anything, but rather that if she wasn't busy with Sis for some reason, it was acceptable to her for the two of us to be together in the same room and not just ignore each other — if one of us got up to get something to drink, for example, we'd ask the other if there was anything they wanted while we were up. There were even several times that the two of us just sat and talked to each other for a little while. I found out from Eva that Charlene thought I was a pretty nice guy, and that she was relieved that I didn't act different toward her.

By the end of the school year, the two of them were all but inseparable the vast majority of the time; it also became S.O.P. for whichever household was missing them to call the other as a first attempt to find them. Once school actually let out, there wasn't any telling where they might be: Eva had not only gotten her drivers license, but Mom and Dad had gotten her an inexpensive (but still in excellent condition) used car: an older Volvo, the blue boxy-looking one. It wasn't fast and sexy, but Sis was still happy to have her own transportation.

The break from school for the summer also gave Charlene and Sis that much more time to spend together during the day… and no reason for them not to spend even more nights at one house or the other.

It was about the middle of July, and Dad had taken Mom on a promised date to listen to our town's little orchestra do a "Symphony in the Park". Charlene and Eva were at our house and had isolated themselves in Sis' room while I was watching a movie on TV. I'd figured that with the two of them back in Sis' room, I'd be able to watch the whole thing without interruption; but that didn't prove to be correct. Roughly halfway through the movie, the two of them came into the living room where I was and stood in their bathrobes off to the side just watching me. I finally paused the movie, turned my head to face them, and plaintively asked "What?"

After they'd looked at each other, it was Charlene that told me "There's something we'd like your help with."

"What, now? It can't wait until the movie is over, or tomorrow, or something?"

"No, not really", Eva answered. "It's something that we'd need to be sure Mom and Dad will both be out of the house for a while."

Wondering why they could possibly need me and Mom and Dad gone, I asked exactly that: "Why would you need me while Mom and Dad are gone? What's going on, Eve?"

Both of them looked nervous for some reason, but Charlene was the one to tell me "Come with us, and you'll see", immediately followed by both of them blushing furiously.

The looks they were giving me finally convinced me to do as they asked. After taking note of where I was in the movie, I shut it off, then stood up and followed them — all the way back into Eva's room, much to my surprise. Eva was the one to close the door behind us, and after she'd joined Charlene again, she told me "There's something that Charlene and I both want to find out, but neither one of us knows anyone that could help us with it… except you. We want to ask you something, and we already know it's a lot to ask, and we'll understand if you don't want to do it. But if you do, we're willing to do something for you in return."

Well and truly baffled at that point, all I could think of was to ask them "What is it you want from me?"

They gave each other a Look, then carefully faced me and undid the belts of their robes. Before I could even take a breath, they'd shrugged their shoulders — leaving both of them standing there stark naked with their bathrobes puddled around their feet. As I stood there (undoubtedly looking as stunned as I felt) looking the two of them over, Eva told me "We… we want to learn about guys. The, um, sex parts, I mean. Charlene only ever saw them on babies, and it's been a long time since we saw each other — I told her about it — and I know that I've changed since then, so I figured you have, too. That isn't something we can ask any other guy to do, so if you won't do it, we'll have to try and figure something else out. But if you'll agree, then it'd be okay if you wanted to do the same thing with me."

To that, Charlene added "You know I have little bit of a penis, but I've also got a vagina… so if you wanted to look at me, too, it'd be okay."

Eva finished up by telling me "We want to look close, and ask some questions, and… if it's okay, even, um, touch. However far it's okay for us to go with you, you can go with us. We figure that kind of encourages you to let us learn what it is that we want to know while keeping us from going too far with it. We're willing to trust that the time we spend looking at you will be about the same as you spend looking at us, but it's okay if you think we should actually keep track of the time."

Hearing that, the first thing to come to mind was that it actually sounded fairly reasonable. But a few more seconds thought, and I had a question: "You said that you were willing to trust that the time would be the same, but would my time be for looking at each of you, or both?"

They had some kind of silent negotiation thing using just their eyes before facing me again so Eva could tell me "There'd be the two of us looking at you at one time, but we know it wouldn't be fair for you to have to try to look at both of US, we'd be okay with it if you wanted to use almost the same time for each of us. It's not like we're completely different; after all."

That wasn't as much as I could hope to get, but was more than I'd have settled for… and easily enough to get me to seriously consider their offer.

Like most guys my age, there was a certain amount of trepidation at the idea of a girl (or worse still, two of them) actually eyeballing my works due to the basic insecurity most of us guys have at that age. But that was far overshadowed by the prospect of having those same girls doing more than just looking. When I added in the opportunity to really look (and touch, if they went that far) their parts… well, it didn't take me long to decide to agree to their request. Yeah, Eva was my sister, and that was kinda weird — but she was still female and attractive, and that was what was most important to me. Charlene left me with mixed feelings, though: the chance to check out another female was definitely enticing, but getting close to her snatch meant also getting close to what was above it — and I wasn't real wild about that idea, regardless of my acceptance of it otherwise.

It took a minute or so for me to work through all of that (and looking them over in the process) before I told them "Okay, I'll do it."

I could see that my agreement was met with a mix of emotions: relief that they hadn't exposed themselves to me for nothing, happy that they'd get to find out what they wanted to know, apprehension about (almost literally) opening themselves up to my exam, and nervousness (which I also felt) about the situation and what would happen.

Since they'd had me come into Evas bedroom, I figured that was where they wanted it to happen; with them already naked, there wasn't anything for me to do but take my own clothes off — a simple matter of slipping of my sandals, pulling off my T-shirt, and slipping down my walking- and under-shorts. I managed to quash the impulse to cover my cock and balls, choosing instead to simply stand there with my hands at my sides as I asked "Where and how do you want me?"

"Lay down crosswise on my bed, about halfway", Eva told me, with Charlene adding "If… if you could kind of lay with your knees at the edge and, um, open your legs, it would be better, too."

Without saying a word, I walked the few steps to where Sis' bed was and got myself arranged as requested. It didn't take but a single look at them to realize that paying any obvious attention to what they were going to do would pretty much mess things up, I simply put my hands behind my head and closed my eyes. To my surprise, it helped me relax a little bit, too. A few moments later, I felt as they joined me (though they were careful not to make any contact).
