Yoshikawa, who married her husband at work, is approached by her ex-boyfriend, who came home drunk and rapes her at night. She indulges in pleasure without her father-in-law or husband finding out. Meanwhile, her father-in-law, who is turned on by his wife's amazing body, notices her affair but turns a blind eye to it and inserts his cock into her hole, wanting to get in as well. The wife is raped one after another, but the pleasure she lacks brings her to orgasm.
