Sadism overflowing from beneath his smock

"You don't like it? But your body is enjoying it." He rubs my most sensitive, wettest part with his finger as my legs are spread wide open... I cum over and over again, so much I feel like I'm going to faint... Asahi is a doctor in training who reunites at a hospital with Yamato, her classmate from middle school. Yamato used to be nice, and they promised that they'd become doctors, but for some reason he's transformed into an unbelievably cold-hearted heart surgeon... "I'll train you," he says, and starts to teach her medicine know-how, but then adds: "I need to relieve some stress. You can pay me with your body," and starts erotically teasing her... Or so she thinks, until he suddenly gives her a long deep kiss just a like a lover would! What is Yamato planning!?
