Manga: The Wiches of Adamas (Vol. 9)

Yukinari swaps one disaster for another when Riamu, his insatiably horny roommate, is replaced by a prissy brat.

Yukinari, the man whose life depends on not coming, must now wage erotic war against Hiro, a succubus determined to make him come by any means necessary!
