Over the next few days, Stiles and Derek couldn’t keep their hands off each other. Every “tutoring lesson” at his penthouse turned into hours of raw, filthy fucking—him bending her over the kitchen counter, pounding her tight pussy while she screamed “Daddy,” or her riding him on the couch, massive tits bouncing as she milked his cock dry. Derek was obsessed—texting her nudes during meetings, canceling plans just to bury his face in her fat ass, eating her out until she squirted on his tongue. He ignored Kate completely—dodging her calls, brushing off her desperate texts for hotel hookups. She had no idea why her lover had gone cold, pacing their mansion frustrated and horny, wondering if work had him stressed. Little did she know, her own daughter had stolen him, fucking him senseless under the guise of math help. Stiles smirked every time she saw Kate’s sour face at home—revenge tasting like Derek’s cum down her throat.
