She finds herself receiving a massage from one of them, naked! Tatsuki tells her, "I'll show you how good I am," and proceeds to touch her in a surprisingly delicate manner... as he touches her in a delicate spot, she can't help but moan. His touch just feels too good... and she can't keep quiet! Though he tells her, "You're my personal training partner," she starts to fall for him... then her other roommate starts to suspect that she's a girl...!
