Monica groaned, twisting the sheets of her bed in her fists as I butt-fucked her, but made no intelligible reply. Taking her silence as license to cum inside her, I doubled my pace, sluicing in and out of her cornhole while she screamed and writhed like a whore beneath me. She let out a bellowing "Fuck me, Ross!" just before her asshole clamped down like a vice around my cock, and I could feel her pussy spasming orgasmically through the wall of her rectum.
My little sister's orgasm triggered my own, and I groaned loudly as my brain liquified and slid out my ears, while my cock exploded in the depth's of Monica's bowels. She let go of the sheets and wrapped her arms and legs around me, the feeling of my load shooting inside her asshole obviously triggering another orgasm.
As our orgasms waned, I pulled my cock out of her ass (luckily not covered in any "love mud") and rolled onto the bed next to her. We lay there for a few moments in post-orgasmic bliss before I felt the bed shifting slightly. Not opening my eyes, I felt Monica stand and then walk to the door of her bedroom, closing it to a crack as she slipped out into the living room. "Probably going to shit," I thought idly, and simply relaxed on my little sister's bed, trying not to think too much about the incestuous act we'd just committed and focus on the pleasure I'd felt while doing it.
A few minutes later, I heard the door open. |
