Derek’s fingers slipped out of Stiles’s spasming asshole, leaving her pink winking hole gaping slightly, slick with her own cum and his saliva. She lay on her stomach on the couch, trembling, her fat ass still quivering from the intense orgasm he’d just forced out of her with nothing but his digits buried in her untouched backdoor. His cock throbbed painfully hard, pre-cum dripping from the tip as he positioned himself behind her, the thick head of his nine-inch monster pressing against her tight, virgin asshole. The office was filled with their heavy breaths, the scent of sex hanging thick in the air like a fog.

Stiles felt the pressure and froze, her porcelain skin breaking out in goosebumps. “Derek… no, wait! Your dick’s too thick… it’ll never fit in my ass! Please, not there… it’s my first time!”
