[Yoriu Mushi] Forest Of Puberty (COMIC MoeMax 2008-03)

In a hidden wooden clubhouse, Urara is stripped bare and put through her paces—naked jump rope to a children's song, trembling climaxes counted on command—while Iyo relishes every second of control over the sweat-glistening girl's small body. But Mori has been playing his own game all along, and when he catches Iyo off guard, he orders Urara to strip her domineering friend down and expose just how soaking wet the bossy girl really is. What follows is a breathless three-way where the line between mistress and plaything dissolves, ending with Iyo panting and thoroughly welcomed as one of us.
