Playing adult games with my super chubby best friend

A group of Meisa Kawakita's old classmates got together to hang out and all. They drank and played sexual games, causing her to lose her reputation as a faithful wife. She and her roommate had a really good fight, even though both of them were a bit shy at first. This girl's body is both white, beautiful, and chubby, and if she gets fucked, it's out of the question. How are those attractive love scenes played out?
