These days, Koo and Taehyung fucked whenever they could — usually once a week when Taehyung sneaked over while Namjoon was at the university or busy with meetings. Sometimes he arrived to find her already getting railed by random cocks — the delivery guy, a neighbor, or even Mr. Kim again. Each time he caught her, he punished her hard, fucking her rougher, slapping her pussy and ass red, and calling her every filthy name until she squirted and begged for mercy.

But now final exams were approaching. Taehyung had been too busy studying to satisfy Koo’s constant hunger. Namjoon, on the other hand, was extremely excited and nervous. He kept telling everyone that if Taehyung scored the highest marks in university history, he would finally become the youngest Head of Department.
