IENFA-39401 - A beautiful older sister, feeling sorry for my pathetic self, allowed me to be in a pure state with the promise of 'just rubbing'. We both felt so good that I became aroused and slipped inside! "Huh? Is it in?" But I couldn't stop it and ended up deep inside! Konami Aya

A pathetic man becomes greatly excited by her defenseless appearance! Knowing it's wrong, he can't resist and masturbates while fantasizing about his sister. But he gets caught and the atmosphere becomes awkward! "Don't men have to release when they're full? I'll help you release." She gives him manual stimulation and fellatio, but he can't quite get aroused, and she says, "I can't let you insert, but I'm okay with just stopping!"?
