[Akimoto Karma] Gael Gael Chicken (COMIC Aun 2012-06) [desudesu]

A friend-zoned boy with an eye-covering bang takes his romantic frustration out on strangers, picking the quietest schoolgirl he can find to expose himself to on a public bench—only for her to turn out to be friends with a bold, dark-skinned gyaru and her circle of merciless classmates. They corner their hapless flasher, mock how tiny he is, and decide his nuisance charges will be settled when their very busty, long-haired ringleader straddles him and demands his virginity as payment. What begins as punishment spirals into a full harem of dominant girls claiming every one of his firsts—and by the final page, his chief tormentor is the one calling him back for more.
