Riho's happy marriage is destroyed when an intruder sexually assaults her in front of her beloved husband and drugs her with an aphrodisiac. Overwhelming pleasure races through her body until she loses control and urinates, while her helpless husband can only listen to her repeated cries of orgasm. The attacker's techniques and drug-fueled sex gradually conquer her resistance; despite her initial disgust, she begins craving his bare cock and even begging him to creampie her.
