IENFH-019 I was messing around with my little sister who goes to an all-girls school while she was sleeping, but then she demanded raw sex. I was about to cum, but she locked me in place with a crab pincer and I couldn't escape, so I ended up ejaculating

A brother helping his sister Fuka with her love problems. She likes a guy from the same club and can't sleep at night. The brother asks, "Are you hungry?" and goes to the convenience store. When he returns, his sister is asleep. Noticing her panty flash through her uniform skirt, he can't help but peek and even touches her body slightly. Suddenly, his sister gives him a deep kiss. "I think I like you, big brother! It's not the classmate anymore, it's you!" she says. "You told me to be more proactive, right? I'm going to be proactive now!" She then performs fellatio and even makes him lick her private parts until she orgasms. She inserts his penis into herself without protection, and when he tries to pull out, she locks him in place with her legs like a crab's pincers!
