POISON CHERRY DRIVE (Poizun Cheri Doraibu), by Modoru Motoni. First published in 2005 and first published in 2006.
PLOT:
There's a site called Cherry Drive that promises to satisfy the needs of any young gay man who applies (although young, virginal ones are preferred), whether that's revenge for a rape or simply to satisfy their most secret desires. If approved, you meet up with the men of Cherry Drive: the frantic president Ai Iidai, the chill Mamezo Takano, and their token straight go-fer Kenny Boy. Their cases never seem to work out quite how they want them to, but somehow things seem to work out.
