Beautiful wife Aiyuki, who wakes up her sleeping husband by sucking his cock, is an outright nymphomaniac. Drooling profusely, she devotes herself to an intense blowjob, her husband fully aware of her actions through his body. Yet frustrated by his refusal to let her cum, she secretly brings herself to orgasm alone. Her face turns deathly pale in panic. However, she has a secret pleasure—she starts roughly groping her large breasts at the entrance, so desperate that she immediately takes out a ruler. Aiyuki, now completely reduced to a sex slave, seems oddly thrilled. One provocative scene follows another—ropes biting into her soft skin, nipples being pinched and tormented. But unexpectedly, her husband, who should have been at work, suddenly returns home! What action he takes upon discovering his wife's true nature...? Be careful not to jerk off too much.
