I’ll pull it out for my sister ~My girlfriend’s sister has no choice but to let me do it~

Original Name: お姉ちゃんの代わりに抜いてあげます ～彼女の妹は、仕方ないからと絶対にヤらせてくれる～
Summary: ❤️❤️❤️ My cool little sister is reluctant but will give in to pressure and let me do it!? I, Uchiki Kyoya, missed the chance to have my first experience with my girlfriend, Mikuna, again today. So sad that I’m getting close to her little sister, Moeru. We’re masturbation buddies. Ever since I witnessed her sniffing my jacket while masturbating, we’ve made a promise to jerk each other off. Moeru is reluctant, but she always gives in in the end. Today, I’m being spoiled and following my instincts, seeking out “her little sister” again.
