Her whole body moved with me now, her legs tensing and relaxing on each stroke and her pelvis shifting beneath my mouth to enhance the pleasure I was giving her. I reached a hand up between her legs and used my fingers on her pussy in addition to my lips, instantly feeling her wet heat. She was vocalizing almost continuously, but my cock in her mouth kept any words from forming.
The intensity was building. The pressure of her mouth, combined with the knowledge that she was melting under me, led me to feel an orgasm beginning to brew within me. But I wasn’t ready yet. Reluctantly, I pulled away from this dual oral stimulation and reoriented myself so our mouths lined up with each other, and our sexy bits lined up with each other.
With the intent to let my overheated arousal cool, I went in for a kiss, this time tasting my lube fresh from her tongue while she must have tasted her own too. With our lips engaged, Allie wrapped her legs around my waist and squeezed, pulling our bodies together until our flesh was in maximum contact. My achingly hard cock was pressed up against her slit, our entire bodies slick. Without breaking the kiss, she started to grind against me, and my intent to cool my arousal was suddenly not so effective.
The feeling of my cock sliding along her pussy was pure ecstasy. I broke our kiss and watched her face. Her eyes were closed and they squeezed tight with every stroke of our bodies against each other. Her skin was flushed red, and her lips were parted just enough to show the corners of her front teeth. She was the same adorable little sister as ever, sexier than I could have ever imagined.
After a downstroke longer than usual, the tip of my cock was poised at her entrance, and on the next stroke I was inside her. She said, “Oh my god, yes, yes,” while at the same time holding still with about half of my length inside her. She opened her eyes and we locked on each other’s gaze in stillness.
I’m having sex with my sister, I thought, and I wondered if she was changing her mind about this. I studied her eyes, looking for an answer, but her expression was sultry and deep like I’d never seen before. At last I said, “Allie, is this-”
She didn’t even let me finish the question. Almost imperceptibly, she started to move beneath me, and I took the cue. My shaft began to penetrate her more and more deeply until it was fully embedded and we stopped again. I continued to watch her eyes, and right before they snapped shut I saw the faintest trace of lust.
Allie moaned deeply as we started to move together. I kept myself inside her all the way but moved my body up, down, around, relishing the sounds of excitement from her that were building in intensity.
I stopped and withdrew from her entirely, my cock coated with her cream and throbbing. I plunged back inside her and my instinct took over as I fucked her in earnest. Her moans turned to wails as she squeezed her legs around me harder than ever, our bodies slamming against each other with abandon.
