BLK-630 The little sister who recently debuted as a gyaru chose her brother — me — as her SEX practice partner. Two people with little sexual knowledge and double runaway pistons — 倉本すみれ

About this work

The little sister decided to become a gyaru. She figured that once she became a gyaru she had to act flashy/flirty, so she decided to practice sex! The partner she picked for that was her brother — me! She watches AV, but even I have no real-world experience... Still, if we can't do it well when “the day” comes it would be embarrassing, and there's the dignity of being the brother, so we practiced piston thrusting as siblings! Maybe because we're blood-related, our compatibility is surprisingly perfect! Our strong stamina is inherited too! Not noticing that the other is coming, and even with backflow, our double runaway pistons continue with massive follow-up creampie ejaculations inside!
