ジャッカス！

Keisuke Hara is a blunt high-schooler who lives with his older sister Akiko and has never quite swallowed how easily his rich, good-looking best friend Masayuki Shinoda gets whatever he wants. One rushed morning Keisuke pulls on a pair of Akiko's stockings under his uniform by mistake, and Masayuki spots them in gym class, unleashing a fetish he had kept to himself. What starts as bickering between two friends turns into something neither of them planned, and both have to work out what they actually want from each other.
