Reiko calls for a repairman to fix a leak in her bathroom, but the worker becomes intensely aroused by her mature body and suddenly rapes her. Though Reiko feels guilt for having sex with a man other than her husband, she can't suppress her pleasure and repeatedly gushes with orgasm after orgasm. For the "repair work," the workers restrain her and bring her to climax using vibrators and electric massagers. Then, the hungry workers thrust their cocks deep into Reiko's womb, making her scream in ecstasy as she undergoes repeated, intense squirting orgasms, climaxing wildly until she's finally released.
