MIDE-733 — On That Day, While I Was Visiting My Parents' House, My Girlfriend Was Having Sex With Her Best Friend In The House Where She Was Living Together, And She Was Having Multiple Orgasms.

Mizuki, my best friend's girlfriend who lives with him, is so cute that I'm jealous... I happened to peek at them having sex and discovered the spot where Mizuki cries out "that spot" - her sensitive weak spot. I want to have that sensitive body myself! Unable to suppress that desire, I decided to make my best friend's girlfriend cum while he was away at his parents' house! At first I f** myself on her, but as I accurately hit her weak spot, she gradually started to ask for it herself.
