Tatsuya is married and lives with his wife and mother-in-law. His heart wavers at the occasional cuteness of his mother-in-law. One day, she buys an aphrodisiac cream. After trying it, its effects are perfect. Hard nipples and a ripe vagina make them unable to stop. The two begin their forbidden relationship. Overflowing love juices, seeing his mother-in-law in pleasure drives Tatsuya to ejaculate inside her. Hooked on the intense pleasure, the two indulge in each other in the bathroom, Japanese-style room, bed... repeatedly, in this tale of incestuous debauchery.
