Shinobu Kasagi, who was once a huge hit as a loli masochist actress, makes a splendid comeback! She appears in the popular series Forbidden Caregiving! A wife is frustrated because her husband is busy and they haven't had sex for over a year. One day, the wife suddenly gets a fever and is bedridden. She feels gratitude towards her father-in-law who devotedly nursed her back to health, but she also feels something else. The frustrated wife continues to seduce her father-in-law at all costs. The father-in-law can't resist his wife and finally bites into her body. They passionately entwine their tongues, lick each other's crotches, and move on instinct, becoming one.
