Yu-Ri leaves her husband alone for days to be at her parent's home to clear her head. She had called Yu-Mi in advance to take care of him in the meantime. Su-Heon takes the opportunity to make advances on her.
Driven by his cuckold kinks, Batino hires Tae-Yang to "train" his wife, Verdia, over a marathon session using 16 condoms. Since Verdia has never had truly passionate sex, Tae-Yang takes his time teaching her everything until she’s completely overwhelmed. Once all the condoms are used up, Tae-Yang uses a cute, childlike act to convince her to go raw. The encounter peaks with Batino checking in from outside the door while Tae-Yang finishes deep inside Verdia. After Batino leaves, they continue to have sex for hours until Verdia is exhausted from the pleasure. Afterwards, Tae-Yang presents a thoroughly worn-out Verdia—now adorned with multiple condom belts—back to her waiting husband.
