The lips that were sliding up and down my erection didn't hesitate in the slightest, though I did hear and feel the "mmmm-hmmmm" acknowledging my warning; that added little bit of vibration was all it took to trigger my climax, and I heard myself groan as the first wad of my jism erupted from my cock.
Before the second could escape me, the warm mouth that I'd enjoyed pulled off, allowing my semen to arc onto my belly. My disappointment at the loss of the living receptacle for my cum lasted only a moment; my pulsating penis was again tightly gripped by a pair of lips, and the head enveloped by a warm and wet mouth that stayed around me until the last feeble spurt of semen had leaked out of me.
When it was clear that I was finished, the lips clenched me a little tighter and milked my shrinking penis of the last few drops of my juices as it pulled off of me.
After I'd gotten my breath and senses back, I raised my head to look down to where Charlene and Eva were sitting; even after looking at both of them closely, I couldn't tell which one of them had taken the first shot, and which had finished me — both were sitting there with cat-that-ate-the-canary grins on their faces as they looked at each other. Only when I moved to sit up did their attention shift from each other to me.#p#分页标题#e#
Both were looking rather pleased with themselves when I told them "Thank you — both of you. That was even better than what you did the first time."
I got a self-satisfied smile (and small blush) from each before Eva told me "I'm glad you liked it. It wasn't like what I thought it'd be at all. It was actually kinda fun, and it made me so excited, knowing that I was able to make you feel that good just using my mouth. And I really like the taste of your juice!"
After a moment, Charlene told me "I really liked doing that, too" — I knew she was telling the truth, since her penis was again standing at attention — "I wasn't real wild about tasting your stuff before, but somehow it's different when I get it straight from you… I actually kinda like it, even."
After that, the next several minutes were spent with the two of them comparing what they thought about what they'd done. A few questions were directed toward me, but my opinion of things was simply that I'd enjoyed the hell out of the experience, so there wasn't much for me to add to what they were telling each other. Listening to them talk, however, did leave me feeling both surprised (that they both concluded that it was a perfectly reasonable thing to do with a guy) and pleased (that they'd enjoyed it and were quite willing to do it again "sometime").
Their conversation had mostly tapered off when Eva turned toward me and asked "Billy, do you… do you want to learn about girls now?"
"Yeah, I'd like that — a lot. Especially with you two!", I assured her, and earning myself a pair of very pleased smiles.
"Which one of us do you want to start with?", Charlene asked.
I looked at her, and apologetically answered "I think Eve, if it's okay."
Charlene didn't bat an eye as she told me "Sure, that's fine. I mean, she is your sister…"
I looked into Charlene's eyes and sincerely told her "Yeah — and that's the only reason", so she'd know it wasn't because of anything else.
When I returned my attention to Eva, I saw that she was watching me closely and that she seemed to be sitting differently. It took a few moments for me to realize that she wasn't just tolerating having me looking at her and touching her body, but actually looking forward to it. The very first thing I just had to do, of course, was raise my hands and put them over her breasts. I think both of us released a soft gasp at that first contact, and as I began gently and carefully examining those most obvious signs of her femininity, Eva closed her eyes and pressed herself against my hands.
I was delighted with the feel of her mounds; they were somehow both firm and soft when I cautiously squeezed them, as well as smooth and warm under my touch. The peaks of her mammaries were already tight and crinkled, but when I started examining them with my fingertips, I was surprised and delighted to learn that they could get even tighter, and that her nipples could stick out more than I'd ever seen them before. I happily spent several minutes acting pretty much as you'd expect any adolescent boy would with his first pair of real, live breasts in his hands. But as nice as Sis' tits were to touch and hold, their dark pink summits were something I just had to get my mouth on.
As soon as I had Evas nipple between my lips, she released a gasp that was followed by a soft moan as I began to nurse at the pink peak of her breast. It was only a matter of a few seconds before I could feel her nipple getting longer and the areola grow harder as I laved them with my tongue. When I shifted my attentions to the other half of her bust, she raised her hands so she could put her fingers in my hair and hold my head in place — as if there was any danger I was going to stop any time soon!#p#分页标题#e#
