Her best friend, the busty girl... Koiro-chan tempts me with her breasts whenever she gets the chance, creating a troublesome relationship. "I liked you first." I realized she had a sexy appeal that she didn't have, and my dick was succumbing to the temptation of her best friend's 'boob pussy'... "It's not cheating if it's just a titjob, right?" The devil's whispers easily blow away my rationality. I give her a titjob every day when she's not looking. The sense of guilt makes me want to do it more than usual...
