Seolyeon, the wife, is unsatisfied with her night life with her rigid scholar husband, Jinheon. One day, Seolyeon receives "Toryeomsul," a treatment said to help achieve satisfying union with her husband and aid conception. But this Toryeomsul is somehow strange.

"How can you tell me to commit adultery with another man, not my husband!"

"This is not adultery, Madam. It is Toryeomsul solely to loosen your gyeonpo."

"Hee-euh, aah! Ha, euh, euheut!"

"As your po was so stiff, it's natural you couldn't respond to your husband's penis."

"Ha, aah! St-stop... Now, aah! Stop...!"

"Didn't the physician tell you? If you stop Toryeomsul midway, your po will stiffen even more."

Baekhyang forcefully thrust his penis, thoroughly soaked with vaginal fluid, repeatedly deep into Seolyeon's cervix.

"Never stop."
