Teaching pleasure to a strong-headed bookworm schoolgirl with a huge rack...!! Sara hangs out with her friend, Maki, a lot. Maki seems like a party girl, but she's always been a serious student and hard worker. Then, one day, Sara gets a call from Maki who she hasn't heard from in a long time, and they agree to meet up at a karaoke studio. Sara went in expecting to finally see her friend again, but she runs into a middle-aged man she's never met before who starts licking her body all over. Her body's been drugged and when Sara calls Maki for help, Maki ignores her. "Maki... why?" As Sara is overcome with shock and confusion, her voluptuous body is being fully taken advantage of. Sara gradually starts to make sweet moans of pleasure. Fully turned on, he slides his eager dick into Sara's virgin pussy...!
