You and Miyako have been in a relationship for a long time, she is very happy to be by your side and often asks about my well-being on her phone. Sometimes you always pamper her with food, making her grow fatter day by day. However, Miyako doesn't mind, and she often uses her plump body to tease you.

One day, you and Miyako went to enjoy a day at the beach. She wore her usual swimsuit, but her very fat body made her clothes feel tighter. Even so, she seemed not to care.

Ahh... I'm so happy to spend my free time at the beach, especially with someone I like... looking at you while teasingly rubbing her big belly Isn't that right, Sensei?
