Chapter 7

Krista raised her eyebrows. "So you want to practice that sometime?" Her voice seemed to raise in pitch a little, like she was surprised, or even hopeful.

"Sure. We've still got time before Mom and Dad get home."

"But, you've already cum…"

I was confused. "So?"

"So, guys hate doing that. The only reason a guy does that is so you'll do something back. But if they've cum, they won't bother."

"What?" I shook my head. "Is that what Tommy did to you?"

She shook her head. "Just what I hear from friends. Tommy's never licked me down there. Actually nobody has. Guys just think it's gross to do that."

I shook my head in wonder. "The evidence for Tommy being a closeted fag is only increasing." I didn't really know if eating a girl out was gross or not, having never done the deed. I'd heard people say it was, that it tasted like strong fish, but I'd also heard people say it wasn't at all, that they even enjoyed it. The one thing I did know was that girls were supposed to like it, really like it. And if you're like me, full of self-doubt about your own abilities in other areas, you don't want to shy away from something that supposedly makes a girl cum better than anything else. If I could somehow get good at it, it would be like a secret weapon. Even if it really was gross, I imagined I could fake my way through it. Fish wasn't so bad. "I've never done it either, but I'd like to. Even now."

Now she was blushing and looking all over the room except at me. "Okay," she said as she got to her feet. "If you really need to practice it, I guess we can start now."

She dropped her shorts quickly, then, more slowly, the pink panties beneath them. I'd already seen it so I didn't know why she felt she had to tease, waiting a few seconds before the final reveal, but maybe girls are just built that way. It wasn't long before they were gone, and she climbed on the bed. She removed her socks and looked at me. "So, on my back?"

I nodded, got out of the way so she could stretch out, and then went to the foot of the bed so I could rest myself there. She lay back, looking at the ceiling, but her legs were spread slightly. I lowered myself down between them, my face right in her crotch.

It was even more beautiful close up than it was when I'd seen it the other day. It seemed to glisten a little, the light hitting her wetness just right. I didn't detect any smell except a little bit of sweat, but it didn't smell bad, like B.O., either. I took in a deep breath, and the scent, elusive, faint, seemed to escape from my lungs and go straight into my heart, causing it to flutter a bit and pump faster on this strange new fuel.

I took an experimental lick, from the bottom of her hole to the top of the little nub, and Krista shuddered violently in surprise. "Is that okay?" I asked, suddenly freaked.

Her voice seemed a little weak and wavering. "Yes," she said. "I just wasn't expecting it." She was quiet for a moment, and then added, "You can keep going, if you want."

It didn't taste bad. It didn't taste like much of anything, like licking bare skin, almost, but there was something in the not-taste of it that was arousing all the same, so I took another lick. I spread her lips aside with my fingers and licked the edges, and then, trying to imitate what I'd seen on videos of the Internet, flicked my tongue from side to side rapidly.

Krista's mound rose and fell in undulating waves, she must have been flexing and releasing her butt to pull that off, but since it looked like she was trying to meet me, I had to assume she was enjoying it, and kept up my work. I tongued around the clit and then went down to the hole, which seemed to have a faint metallic tang to it, but nothing too unpleasant. It had been a while since I'd last seen a porn movie, but I remembered guys, or girls, usually used their fingers too, so I stuck a couple in her hole while I licked closer to the top of the slit.

A few minutes in, my tongue started to get tired, but Krista, who had been whimpering softly in pleasure, was bucking more and more against me. I wasn't about to give up… if I sprained my tongue, so be it, at least I'd have done so in a good cause. I realized I could give my tongue a little bit of a break by focusing more on my fingers and using my lips to kiss her softly and even provide a little bit of suction. She yelped out a little when I tried to suck on her clit, and I looked up at her. "Was that bad?"

She spoke through deep breaths. "No, it was good, but… too much. It's too sensitive there."

I took the advice, figuring it might be like the head of my penis. It felt great, but too much pressure right on it was just too much… but then, at the right time, it was made it so much better. So, I waited, keeping it in reserve, licking her in other places and keeping up a steady motion on the inside with my fingers.

Soon, she began to speak, urging me, "Keep going." As though I was planning to stop. "Keep going. That's it… mmm."

She seemed to be clenching more and more, both her ass, so she grinded up into me, but also inside, on my fingers. I figured she was close, so I returned to her clit, and kissed on it, letting just the top of my tongue through to tease it.

"Oh god…" Krista cried out, and rose once more into me, practically shoving her cunt into my face as she let out a wordless cry. Then she dropped, and was still, and she let out a deep, content breath.

"So, how was it?" I asked.

"That was great," she said finally. "I never thought it would feel like that. I don't think you need…." She trailed off. "I mean, it was awful, Bobby. Just horrible. I think you need a lot more practice on it." She sighed. "I guess I can help you out with that though, since there's nothing else to do in this house without all our electronics."

I grinned, not taking her seriously. "Okay. Thanks, Krista. I really want to get it right, as long as it takes."

We didn't want to risk anything else, because our parents would be home soon, and I guess we were feeling a little awkward around each other again, being naked around each other even after we'd both cum, because she dressed and went to her room and I stayed in mine. After a good half hour of lying on my bed, staring at the ceiling and savoring the memory of what had just happened, I started looking for something else to do. Eventually, I chose homework. On a Friday. I was that bored. If only Mom knew that taking away everything fun left us nothing to do but homework and incestual oral sex with each other, she never would have started us on this challenge
