Chapter 30 Your Cock Feel Good(Incest/Taboo Sex)-4

Her hips chased me, trying to keep me inside. "F-- faster, Matty. I-- I can-- oh oh god-- please!" My resolve had already been straining, and this put it near the breaking point. I didn't fuck my sister, not in the rough way that I might have wanted to as she urged me on. But my lovemaking became less gentle, more rapid than perhaps it should have been. She winced in pain once, and I tried to slow, but then she grunted, "Fuck me, big bro! Fuck-- AH!" She got her wish. Sammy was so tight that when her climax started to come, it was like being gripped by a silken fist. She moaned loudly, finally begging, "In-- in me! S-- Safe, pill!" I only had to hold a little longer, just a little-- and then I felt her contract around me, felt her whole body go rigid as she fell silent. Sam held there for a moment, paralyzed, then exploded into motion, shuddering violently as she cried my name. I buried myself to the hilt in her as ropes of semen painted my sister's cervix. My body pinned hers to the mattress, and my mouth muffled her moans.
