FPRE-217 | I live alone and my sister is a sex-challenged sister who hangs out in my room, but I've finally discovered her arousal nipple switch that unleashes her sexual desires! She's awakened as a slutty bitch and milked me of every last drop of semen. Himari Kinoshita

I'm a college student living alone near my parents' house, and I have a big sister named Himari who's also a college student.

Perhaps because of her flashy looks, my parents don't allow me to live alone, so I'm forced to live at home. To relieve stress, she comes over to my room and lazily plays her favorite games.

Today, Himari played games until late again, and I tried to urge her to go home, but she refused, saying that her parents would nag her if she went home. Himari, who has noticed that I've always had lustful eyes for her, made a suggestion.

And that is... she'd lend me her pussy while I was playing a game in my room.

Himawari, who has yet to experience the pleasures of sex, has an extremely low threshold for sex, and despite my virginity getting turned on, she casually made this suggestion...

As I was shaking my hips with gusto, my sister was the complete opposite, completely unresponsive. "I really want to hear her sexy voice..." I thought, so I studied hard and finally found what turns my sister on!

After discovering a pleasure she had never known before, Himari started coming to me for sex instead of games...
