It was the summer before my junior year in high school, I was sixteen, and so was my twin sister Kate. We were about as different as twins could be, except for looking alike.
I was a bookish, intellectual nerd. I like sci-fi, comic books, and school. I had friends, but I had never had a girlfriend. I was shy, quiet, introverted, and very reserved.
Kate on the other hand was a firecracker! She was very brash, outspoken and energetic. A spoiled brat. And she had a very active social life, she must have had about a million boyfriends, sometimes two at the same time. But, being the pretty little thing that she is, she was very picky. She would not go out with any boys in our class. Only seniors and college guys. And the occasional illegal liaison with a rich, married man.
Our cousin Ellen was visiting, as she did every summer. She was 19 and on her way to college. All our lives Kate and I worshiped her. She was older, but so cool, very much an 'It' girl, and we wanted to be like her. She was absolutely a role-model for my sister, who was succeeding in becoming the cheeky socialite that my cousin is.
When the two of them hung around together, their antics just got wilder. They seemed to feed off of each other, and when I would be with them, their conversations would veer off in directions very much off of my radar. They were boy crazy, and since they had so much experience, they talked about boys all the time, in a graphic, raunchy fashion.
They teased me relentlessly about my virginity, and say blatantly sexual, dirty, naughty, and explicit things just to make me blush. Although I would feel embarrassed, I was actually secretly aroused hearing my beautiful twin sister and cousin talking so dirty.
One morning we were just lounging while my parents were at work. It was a hot summer day, and the girls had been sunbathing in the back yard in their little string bikinis, talking about who knows what.
We were sitting around the table on the patio. They were drinking beers and smoking cigarettes, while I was sipping a lemonade and reading Steven Hawking' s "A Brief History of Time".
As usual, their conversation started getting naughtier and naughtier.
"Of course, all guys' cocks are different! If you lined up the cock of every guy I've fucked, I could tell you who is who! Although it would take a long time, considering how many I've seen!", giggled Ellen, remarking on her own promiscuity.
"No,", countered Kate, "In your case, Ellen, you might be able to tell if it was jammed in your mouth,", she laughed at her own joke, "but if you only saw his cock, you wouldn't recognize him from it."
"Wrong, I'm a connoisseur. You just need to see a few more before you learn the proper profiling method.", said Ellen. They both laughed hardily at this remark.
This type of graphic, dirty talk was typical of them when they were together.
Ellen continued, "Hey, wouldn't someone with a cock know better than us girls? If only there was someone with a cock who could enlighten us? Gee, I wonder who might know better...."
Oh, no, here we go again!
"Leave me alone, I'm trying to read.", I responded.
Ellen persisted, "Michael, you do sports. I'm sure you've seen alot of cocks swinging around in the locker room. I'm sure in your lifetime you've seen at least two or three more guy's cocks than we have,", and, like Kate, she laughed at her own joke. "Tell us, are they different enough that I would be able to recognize them." She realized how uncomfortable this was making me, and she and my sister giggled, delighting in watching me blush.
"I suppose if there was one with an unusual feature, or particularly unusual size, you might be able to match the penis to the man.", I scientifically replied.
My sister squealed, "Oooooh, so it looks like my twin brother spends a lot of time observing cocks! Ooooh, maybe that's why he doesn't have a girlfriend!? Tell us more about cocks!"
"I am no longer interested in this conversation.", I replied curtly and got back to reading my book.
"Well,", Ellen continued, "if you don't want to talk about cock, like we do, what about pussy? Do you think you could tell two girls apart just by looking at their pussies?"
This was another taunt aimed at my virginity. I ,of course had never seen a woman's vagina, except in pictures. Being a nerd, I obviously looked at alot of porn. But from the porn I watched, I did start to become a connoisseur of vaginas, and thought I could make out the difference.
"Yeah, I think I could." I replied with confidence.
They both squealed and giggled uncontrollably. The were sitting next to each other, Kate's nearly naked body draped over Ellen's and they gave each other playful slaps on the arms as they laughed at the virgin telling them he knew so much about vaginas, having never seen a real live one.
"Ha, ha, we have an expert here!", taunted Ellen, "I suppose being the budding scientist you are, you can set something up and prove your little theory?"
I tried to act as cool and confident as I could, "Well, the experiment would be to show me at least two women, clothed, of course. Then we would do a 'blind test', as it's called in science, where I would see their vaginas, and only their vaginas, and I would match the vagina to the woman. Of course, for the experiment to be truly rigorous, there should be substantially more than two women, or the statistical standard deviation would be pretty much arbitrary."
They howled, knee slapping, greatly amused by my response.
Kate shouted, teasing, "Oh, 'vagina'!!! My twin brother can't even bring himself to say 'pussy', what a Poindexter! No wonder he can't get laid!"
Ellen was a little cooler, "Well, Michael, if you stand by that, I'm sure we can set up a little trial experiment."
She took Kate's elbow and they both stood up. I looked at their hot tanned bodies, in their little string bikinis, standing in front of me, and wondered what was coming next.
Ellen said, "Michael, if you want to conduct your experiment, you have two pussies, oh, sorry, I mean 'vaginas', right here. Maybe you want to test your theory?"
With that she began to stroke her hand over her crotch, over her skimpy bikini bottom.
My sister noticed this and began rubbing herself over her bikini bottom. They both looked at me, mischievous, sadistic grins on their faces. My twin sister and my older cousin, behaving this way, I should have just walked out, but felt compelled to stay. I assumed this was just them making fun of me, something they often do. This was on a quite higher level than any previous misbehaviours on their part, but I was afraid this was just another prank on their part.
"Don't think so." I responded.
Without a pause, still stroking herself, Ellen shot back, "Ha, I challenge you, I bet if you saw our spread out ' vaginas ' (she said vaginas with a sarcastic, mocking tone), you wouldn't be able to tell who was who? Let's see just how brilliant you are, virgin! What kind of stakes do we need to put on the table for you to take this bet and prove yourself?"
I tried to act cool, something I'm not very good at, "OK, how much money will you give me if I can do it?"
It occurred to me that what they were proposing, and I was eager to accept, was that I would inspect their pussies and determine whose was whose. My twin sister's and my cousin's. If they weren't my close relatives, I would have taken this without hesitation, but....
My thought was interrupted by Ellen's laughing remark, "Michael! You know what spoiled rich girls we both are! We don't have any money, we just buy stuff on our credit cards and daddy pays, it has to be something else..."
My sister jumped in, "Oh, Michael, if you get it right, you can pick one of us and have your way with whoever you choose! You get to fuck one of us! You'll get to finally lose your virginity!"
I couldn't believe my sister just said this, neither could Ellen, I think.
"Kate, you are such a dirty girl! I thought you only fucked older guys. He's your age! You filthy, naughty, shameful slut, talking like that to your brother! And he's not even a senior yet! Incest and lowering of your social standards! You whore!", she said with false shock and disdain.
Kate, pretending to ignore Ellen, "Oh, Michael, if you win the bet, please choose me, choose me! I would love to be your first!"
Ellen shot back, "No, Michael, I'm older and more experienced than your sister, choose me, please!"
Kate yelled, "Ellen, you bitch!"
They got into a pretend cat fight, slapping, wrestling, pulling each other's hair. It was exciting seeing my nearly naked sister and cousin going at it this way, in their little bikinis, cat fighting. But again, I didn't know how to respond. The cat fight ran its course, and they were back on their deck chairs, giggling as they always do, embracing each other. They looked back at me, still sitting in my chair.
"Well,", Ellen asked, "Wouldn't you like your scientific skills to be rewarded by sexual rights to one of these beautiful young ladies here? Oh, but maybe you're not as smart as you think!" Again, they both giggled tauntingly.
I tried again to be cool, "But what if I lose, then what? And I'm certainly not giving either of you any of my money. If I can't figure it out, what are the consequences for me?"
They started giggling uncontrollably. I was impatient, although I enjoyed watching them embracing each other as they laughed. They exchanged a knowing glance.
"Then we get to spank you. Bare assed. Is that worth the risk?", Ellen laughed.
I assumed they were kidding.
"I'm out.", I replied, but so meek it was clear I was just saying that because I thought I should.
"Oh, he can't take it,", mocked my sister.
"I can take it!", I protested.
"Then why don't you take the bet?", Ellen taunted.
I didn't know how to answer. Certainly, getting my first glimpse of a live vagina would be thrilling, especially from these two hotties, and getting to pick one to lose my virginity, too? Who would pass that up? OK, although this was my twin sister and my cousin, if this was their own idea, than I was going to follow through.
"You're on!", I challenged, as I looked at the two girls laying in their bikinis in each other's arms, wondering which one I would choose when I won.
"Oh, not as much of a wussy nerd as we thought!", Ellen said, "OK, here are the rules. We're going to go to Kate's room, undress, and cover ourselves so you can lift up the blanket and see only our pussies. You are not allowed to pinch us or try to touch anywhere else. You can look at our pussies as long as you want..."
Kate interrupted her, "In fact, inspect them! Feel free to touch, smell, taste, hee hee hee!"
Ellen thought that was great, "Yes , inspect us all you want, just don't look or touch anywhere else. When you've made your scientific conclusion, step back, and announce whose was whose. Then we let you know. And what follows is what we've agreed upon. Simple enough, right?"
I nodded in agreement.
"Ok,", she took Kate's hand, "Let's go!"
They both leapt out of their chairs, kicked off their flip flops, and skipped into the house. From behind, in those skimpy thonged bikinis, they were as good as naked. It was a nice thing to see.
I waited about ten minutes. I was aroused but got a little nervous about losing. But I had an ace up my sleeve. Since those two were incapable of keeping their mouths shut for longer than twenty seconds, they would at some point open their dirty little mouths, and I'd be able to tell by their voices who was who.
I made my way to Kate's bedroom. The door was open and I stepped in and they were both on her bed, the comforter was covering both of them completely from their heads to their upraised knees.
I went to the one on the left first, and eased my head in under the tent-like comforter and took my first look at a real live pussy. Her pubic hair was shaved completely, which was typical for my twin sister and cousin, so vain about their bodies. I got closer to it, looking at the nice pink labia lips, and the smooth mound above it, and the little fold of skin above her clitoris. It was perfectly symmetrical. It almost looked like a painting of what a vagina should look like as opposed to what one actually does look like.
My face was about two inches away, and I got my first whiff of what an aroused pussy smelled like, a musky, earthy, yet sweet smell. I sat there and took in this new odor and decided to move on to the next one.
I went under the comforter on the right and got my head under. The first thing I noticed was that this one was not completely shaved, right above the mound in the pubic area there was a vertical line of trimmed hair (found out later, this is called a 'Brazilian'). It was quite a challenge to wonder if my twin sister or my cousin would do this bit of pubic manicuring.
The pussy itself was very much like the other, just a little bigger. This would lead me to think it was Ellen's, because she's older, but I don't think the size of the vagina has much to do with age after a woman is fully developed.
I got close to this one, too, and sniffed, it had that nice smell, this one a little tangier, saltier, very nice. I got lost in this for a bit.
Then I heard their inevitable giggling, muffled because of the blanket over their faces, and they were giggling at a higher pitch, like Betty Boop, so it was hard to differentiate their voices.
Then they started saying little 'oooohs', and 'aaaahs', and 'Oh, I bet he's enjoying this!' And their previously unmoving bodies were quivering. I figured, now that the two motor-mouth brats were talking, I would easily figure out who was who. But I was wrong. They squealed and giggled in unison, not saying the same words, so when one was talking, the other was talking, too. How did they do this?
I found out later that they were holding hands and would give a squeeze whenever one wanted to say something. That way, if one talked, the other talked at the same time, and I wouldn't be able to tell who was who in the cacophonous stereo of these sluts' voices squealing and giggling away in unison. And they were raising the pitch of their voices to make them harder to tell apart.
I had my face about two inches away from this beautiful, glistening vagina with the Brazilian pubic cut and had to do a quick analysis of whose this could be. I decided it must be Ellen's because trimming this design on your pubic hair must require some effort. My twin sister Kate was epically lazy, getting her various boyfriends to do her homework, I didn't think she would bother with the effort, she would shave it all off so she could watch more TV.
Suddenly, I felt a hand grab the back of my head and push it right into her glistening vagina.
"Fuck me with your tongue!", their voices rang out in unison.
I tried to pull away, but that one hand held me there strong. My mouth was closed and her hand (whose hand, I still didn't know, but was sure it must be Ellen's) pushed me harder, as my face rubbed again her vagina, I could feel the heat coming from it, and the gooiness of her vaginal juices smearing all over my face.
I resisted for a bit, but could not pull away, so I relented. I found the point where the vulva opening was, opened my mouth and plunged my tongue inside. I loved the sweet, pungent, tangy, and with a hint of a metallic flavor of it. I continued to plunge my tounge in and out, and also licked her clitoris, while her strong hand held the back of my head. I was sure this was my cousin Ellen.
As my mouth continued to work on her vagina, I felt her start to shudder, I was so lost in this experience, I wasn't even thinking. She continued to push my head into her vagina, as I continued licking and sucking....
