She seemed like a gentle and quiet girl, but her younger sister Yuuhi was incredibly erotic... It all started when I was teaching her. I stole a touch of her body while her sister wasn't looking. Suddenly, she began to greedily suck my dick, oh shit, her sister is right there... Tortured by the sense of taboo yet climaxing from the pleasure! Later, while she slept, I jerked off with her feet, carefully licking and sucking her ears and balls, even her ass which she had never been licked before, was licked rapidly. I felt bad for her... but that feeling vanished as I got too aroused. No matter how many times I came, her insatiable sex drive made me insert my dick! With copious amounts of love juice, making lewd sounds while riding on top and cumming inside during her sleep... I thought she was a kind and innocent girl, but she turned out to be a psycho sex killer who loves thrills and pleasure. Before I knew it, I had become Yuuhi's captive.
