My roommate's big, black cock was a temptation I couldn't resist. I teasingly asked him to help me cum, and he eagerly accepted. His huge dick pushed against my tight asshole, slowly inching inside. I could feel every vein, every throb as he filled me completely. My pussy swelled, aching for attention, as he started to fuck me. His big, round balls slapped against my clit, driving me wild. I begged him to fuck me harder, and he delivered, his thick cock stretching my ass beautifully. I came undone, my ass milking his dick as he grunted and filled me with his hot cum.
