愛しのXLサイズ

Aoi Yamamoto is 20 years old. Determined to get his first girlfriend, he joined a Nihonshu Club...only to find it chock-full of men. Disappointed, Aoi overindulges, and is taken home by a fellow club member to recover. This club member is also a virgin, even though he's had many girlfriends, and when he shows Aoi why, well...Aoi finds he wants to try it out for himself. (Source: Kodansha USA)
