[FPRE-217] I finally found an estrus nipple switch that releases the sexual desire of my frigid older sister who is not interested in immersed sex in my room who lives alone! I was awakened to a lewd and squeezed out every drop of sperm Himari Kinoshita

As a college student who lives alone near my parents' house, I have a sister who is also a college student. Perhaps because of my flashy appearance, my parents didn't allow me to live alone, so I was forced to live at my parents' house, and as if to relieve that stress, I would come to my room and play my favorite games. He urges Himari's sister, who was playing games until late today, to go home, but when she returns to her parents' house, her parents will be nagging her, so she refuses, saying she doesn't want to go back. And Himari, who had noticed that I had been looking at myself with erotic eyes for a long time, made a suggestion. It is... While renting a game in the room, he will lend me his. Himari, who still doesn't know how good sex feels, has extremely low hurdles to sex, and despite being a virgin, she makes this suggestion even though I'm a virgin... My sister is the exact opposite of me, who shakes her hips hard while getting so excited, and is completely unresponsive. I thought, "I want to hear a naughty voice after all...", so I studied hard and finally found the switch that my sister felt! Himari learns the pleasure she didn't know before, and from then on, she comes to have sex instead of a game...
