My law's in-law, a married woman with a hunger in her eyes, corners me in the kitchen. "You're just like your brother," she purrs, her hand reaching out to stroke my growing bulge. I'm taken aback, but my body responds, my cock hardening at her touch. She leads me to her room, her tight pussy already dripping with desire. She pushes me onto the bed, straddling me as she grinds her hips, her wetness soaking my cock. "Fuck me, like you would your own sister," she commands, and I do, pounding into her, her tight pussy milking my cock as we both come undone.
