Yu is normally the perfect girlfriend: always smiling, openly affectionate, and endlessly devoted. But her sweetness starts to feel too predictable, and her boyfriend foolishly cheats. When Yu notices his changed attitude and discovers the betrayal, her angelic demeanor snaps. She berates him as a disgusting loser and glares at him with cold contempt—only to discover that her rage makes him hard. Realizing he is a masochist who wants even more abuse, the furious Yu becomes an obsessively dominant tease and drains his guilty erection with endless titjobs. The combination of her anger and enormous L-cup breasts proves unbeatable, leaving him wondering whether he should make her jealous again.
