Don’t come yet.”
“Wait for me… just keep moving your hand… slowly… I’m almost there…”
Her panties felt amazing on my cock and my balls, soft and silky and naughty as hell. Better still, Melissa was sprawled out across the couch from me, skirt bunched up around her waist, legs spread wide apart, juicy pussy spread wide open and totally exposed, her long delicate fingers busily petting herself. It was the hottest thing I had ever seen in my life, and my dick twitched involuntarily. I was going to come, and come hard, whether she wanted me to or not. I bit down hard on my lower lip.
“Fuck, that’s sexy!” she said, slipping a finger up inside her red-hot pussy. “Don’t You Dare Come. Stop it this instant!” I removed my hand, and my cock waggling helplessly, captured by her lacy pink panties. My balls ached.
“Mmm,” she said, rubbing herself languidly, up and down her slit, parting her plump labia. “Who would have thought you were such a nasty, nasty boy? Pull your panties down in the back, I want to see your asshole…. Yeah…”
“I want to see your boobs!” I blurted out like a fool.
Melissa smiled. Smirked, really. “Oh you do, do you? I think that could be arranged.”
She lifted up her top, pulling it carelessly over her head and tossing it aside. It was one of those black stretchy ones that had built-in holders for her boobs. Her breasts were free now, naked and even more glorious than I had imagined.
“Put a finger in your butthole,” she said.
She nodded emphatically, her finger rubbing faster now. I could actually see the wetness drooling out of her.
I did as I was told. It felt weird, and my cock swelled even harder. I could feel the intensity of her gaze on me, hear the squishing sounds her pussy was making.
“Now come for me Babe, come hard!” Her fingers were a blur, her breasts shaking and jiggling, her face flushed red.
“Where should I come?”
“Wherever you want Silly Boy… On my tits… Come on my tits… Now!”
I came and came hard, shouting out loud as the hot sticky semen squirted out the end of my engorged cock, splashing all over her beautiful tits. I came and came, my cock pulsing in my hand, my balls drawn up tight, my anus strangely sensitive and squeezing my invading finger. She came at the same time, head thrown back, eyes squeezed shut, her clit pink and bulging out, captured between two fingers, too sensitive, apparently, to be directly touched.
We were both sweaty, panting. Melissa scooped up a glob of my come, brought it to her mouth for a taste, and smiled. “If you wear those to school tomorrow, I’ll have a very special treat for you after class…”
She wiped herself clean and retrieved her stretch black top. “Now where were we? Oh yeah, we were talking about derivatives and limits. Let’s try a problem.”
