Mari accepts a job as a nude drawing model for a certain perverted artist, but she is constantly asked to pose in embarrassing poses, saying things like, ``I'm not feminine enough, so please let me fold your nipples,'' and although she feels doubtful, she does as she is told. A lewd painter who makes her legs open and draws her close enough to see the wrinkles of her pussy. This time, she asks for a thick vibrator to be inserted to create a sense of dynamism. Mari was holding back, but when the power was turned on, she started convulsing and cumming continuously. She requests a blowjob because she wants to draw a better expression. I can't resist the sticky licking fellatio and plump and elastic titty fuck, so I ejaculate in my mouth. When Mari reaches climax in face sitting position, she can no longer hold back and inserts the dick herself in cowgirl position. Mari is completely excited and convulses many times on the pervert artist's dick. As per the request of the perverted artist, I let the sperm cum inside her, and Mari was very satisfied.
