I sat back and watched Blake fingering his sister for a few minutes. Eventually Ashley reached over and started stroking his penis like I’d showed her. It was one of the most beautiful sights I’d ever laid eyes on. I really wished I’d had a camera out to record it. Oh, well.
“Now it’s time for you to learn a little more, Blake,” I said.
“Get down on the floor.”
“Alright.” He looked up at me as he got comfy. “Is this the part where I have to… use my tongue?”
“Yep. It’s not a bad thing, though. And Ashley’s going to LOVE it.” I winked at the girl. She giggled.
“Ok.” Blake stared down at his sister’s vagina. “So… how do I do this, then?”
“Well, you see that little knob right there?” I asked, pointing to her clitoris.
“Lick that, then down onto and all around her slit, and then if you want, you can try to stick your tongue up into her.”
“Ok.” Trying hard to hide his look of mild disgust, Blake moved his face down between Ashley’s legs and started in. At first there wasn’t any real reaction from her, but then she started to whimper just a little and was soon running her fingers through Blake’s short hair, making delighted sounds as she did so.
I leaned down and started licking and gently biting Ashley’s nipples while her brother continued to eat her out. After a couple minutes I said to him, “If you really wanna drive her nuts, try moving your mouth like you’re sounding out the letters of the alphabet.”
“Ok,” came his mildly muffled (as it were), voice.
“Oooooh…” Ashley moaned. “Oh, yes…” While I continued to play with her nipples, she looked at me and said, “Aren’t you going to get naked, too?”
“Do you want me to?”
Silently she nodded.
I looked at Blake. “What do you think?”
He pulled his face up and shrugged. “Sure, I’m ok with it.” Then he went back to oralizing his sister.
“Alright.” I stood and quickly got myself out of my clothes. I wasn’t in the best of shape. I didn’t exercise much and spent too much time in front of the computer, so I had a bit of a gut starting to happen. On the other hand, I had what was normally a great attribute, namely a rather large penis (a bit more than 9 inches). I knew this would be a problem if I attempted to fuck a girl like Ashley, but it came in handy with other people.
Speaking of my penis, both kids were now staring at it with wide eyes. “Will mine get like that some day?” asked Blake.
“Well,” I said, opting for honesty. “Mine’s larger than normal. But you’ll probably add another three or four inches, sure.”
“Can I touch it?” asked Ashley.
“Sure, if you want.”
Ashley reached out and ran her fingers along the shaft of my penis. “Feels different from Blake’s.”
“Well, yes, it would. I’m not Blake.” I smiled.
She smiled back and wrapped her hand around my erection, stroking it a little. “I like it, though.”
“You like it more than Blake’s?”
Grinning a little she said, “I like his a lot, too.”
“Can I touch it, also?” Blake asked suddenly.
“Yeah, go ahead.” I was very happy with that idea!
Blake put his hand on my penis as Ashley let go of it. I watched this cute little teenage boy masturbating me and felt very pleased indeed!
I could sense that both children were relaxed enough to take this to the final stage. To actually have them fuck. If I succeeded, it would be one of the most amazing sexual things I’d ever been involved in. If I failed… well, at least I’d have memories of what had already happened.
Time to get moving. I took a breath to calm myself and said, “So now I’ve shown you two how to make one another feel good by taking turns doing stuff with each other. Would you like to learn something that will make you both feel great at the same time?”
“Ok!” they both said at the same time, and then giggled.
“Ashley, turn so that you’re laying on your back. You can put your head on my lap.”
“Ok,” said the teen girl as she moved the way I’d told her. Looking up at the shaft of my penis she gave it a little lick and giggled. I smiled at her.
“Blake,” I then said, “you go ahead and kneel between Ashley’s legs.”
“Alright.” He got up off the floor, rather awkwardly positioning himself between his sister’s legs, his almost hairless, virgin teenage penis pointing up at the ceiling.
“Ok! You two are doing really good.” I smiled at both kids. They smiled back, looking a little nervous, but also looking incredibly horny. “Now, Blake. Take your penis in your hand and rub it up and down against your sister’s vagina. Just like a paint brush.”
“So… actually touch it with my dick?” He said after several quiet moments. I’d say it was a pregnant pause, but… no.
“Yeah. Don’t try to stick it in her or anything,” I hastened to add. “Just… well, here, let me show you. Switch places with me.”
I got up and Blake moved over, letting Ashley rest her head on his lap. I saw her hand wrap around his penis, almost of it’s own volition. A very positive sign! As for me, I got between Ashley’s legs and stared down at the virgin vagina of this beautiful sixteen-year-old girl. I was about to be the first person to ever touch a penis to that most magnificent part of her young body. Wonderful!
I took my penis in hand and, as I described to Blake, began moving the head of it all over the young girl’s bare vagina. Each time I brushed against her clitoris, I put just a little pressure against it, and each time I came across the entrance to her vagina, I pushed slightly into her. Not enough to really even justify the word “penetration”, but enough.
“You see what I’m doing, Blake?” I asked quietly.
“You think you can do it like this?”
“Oh, hell, yeah.”
“Ok. Let’s switch places again.”
We moved around again, and when I sat back down and Ashley put her head on my lap, she also took my penis in her hand, just like she’d done with her brother. Damn, that was nice!
Blake settled down between Ashley’s legs and began to slowly rub his penis against her, doing his best to copy all the moves I’d used, including pressing against her clitoris and even doing his best to poke the head against the entrance to his sister’s vagina. I wondered several times if he’d just try to stick it in her on his own, but apparently he wasn’t that bold.
As for Ashley, she had her eyes closed, and several times as her brother’s penis moved along her slit, she would tighten her grip on my erection. It was pretty obvious that she was really starting to get into this.
I now knew instinctively that this was the time. The kids had become comfortable with the idea of their most private parts touching each other. They’d learned the pleasures between their legs that they could give one another. It was time to take this up to the next step.
“You guys wanna try one last thing?” I asked softly, not wanting to break the mood.
“Like what?” Ashley asked, looking up at me.
I reached down and gently cupped one of her breasts. “Well, if you want, you could try letting Blake slide his penis into your vagina. From every girl I’ve ever heard, being fucked by a boy is the best, most wonderful feeling in the world.”
“Really?” She looked from me down to where her brother was rubbing his penis against her vagina. He wasn’t moving around as much as he was, but he was still getting some motion in.
“Oh, yes. You’ll love it. Look at Blake’s face. He really wants to do it, don’t you, Blake?”
Silently, the boy nodded. He swallowed hard and said, in a slightly cracking voice, “Yeah, Ashley… if you wanna let me, I’d love to try it…”
“I’m not sure…” she whispered, lust warring with nervousness.
I continued to massage her breast while Blake kept rubbing against her. “Just try it, Ashley. If you don’t like it, you can just have him stop.”
Ashley bit her lower lip and considered this. She looked at her brother. “If I want you to stop, you will, right?”
“Yeah, of course I will, Ashley. You’re my sister. I don’t want to do anything you won’t like. I love you.”
My heart sang at that last sentence. That was the best thing Blake could have said during this sort of situation.
“I… well… alright. I guess. We can try it.” She sounded a little scared, but resolute. I could tell Blake’s comment had done the trick.
“Cool!” Blake said in a hoarse whisper, his crooked smile returning. He looked over at me. “So, like, do I just put it in, or what?”
“Well, here, let me help you.” I moved out from under Ashley’s head and put a couple pillows under it so the girl wouldn’t be uncomfortable. I crouched down on the floor next to the kids. “Ok, now… Ashley, spread your legs as wide as you can and sort of lift them up a little. That way it’ll be easier for Blake to get his penis into you.”
“Ok.” She did so.
“Right.” I reached down and slid a finger into her tight vagina. She was good and wet. “It’s really nice in here,” I said with a smile.
“Thanks,” she said, giggling.
I pulled my finger out and took hold of Blake’s penis. Leaning down, I rather awkwardly sucked him off for a few seconds, getting him good and wet. With my other hand I used two fingers to spread open Ashley’s vagina, pulled my face up and placed the tip of her brother’s erection against it.
“Are you ready?” I asked Ashley.
She took a deep breath and let it out slowly. “Yeah, I guess so.”
“Are you ready?” I asked Blake.
He opened his mouth like he wanted to say something, but only nodded silently.
“Ok. Just push it in her really nice and slow.”
Blake began applying a gentle pressure and at first nothing seemed to happen. But then, with a suddenness that surprised me, I saw the entire tip of his penis, and about an inch of the shaft, slide into Ashley’s wet vagina. She let out a little gasp and I saw her wince slightly.
“Hold still a moment, Blake.” I turned to Ashley. “Are you ok? Does it feel alright?”
