The latest work from the cute, bashful, and adorable girl-next-door, Mariko Ueda, features her being playfully teased by her senpai on a girls' dormitory bed, with a thermometer inserted, then onto her breasts, belly button, pussy, thighs, and finally her ass, leading her to ecstasy. She's then handcuffed and leashed, dragged around, forced to crawl on all fours, and made to squirt. Despite her confusion, she starts to enjoy it and tries to hold back, but ultimately gives in to her masochistic nature.
