A NEET who stayed shut in at home was constantly nagged by his stepsister to help with housework. One day, finally getting off the couch, he started doing laundry and accidentally tossed in his stepsister's clothes. Her clothes shrank drastically in the wash, and when she realized what happened, she noticed her huge breasts spilling out of the fabric. Confronting him angrily, she caught sight of his erect cock and suddenly changed her attitude, growing closer to him. Perhaps because they weren't blood-related, creampie became no issue between them.
