HUNTA-044 — "When There's An Age Difference Of More Than 20 Years Between Me And My Sister, She's Practically A Stranger, And Even Though We're Siblings, It's Not Really Perverted If I Get An Erection..." My Sister Is In High School, And I'm A Middle-Aged Man Who Has Never Had A Girlfriend.

I'm a useless old man who's never had a girlfriend, but I have a cute little sister who's more than 20 years younger than me. She's grown up in body but young inside. She wanders around the house in light clothes and is defenseless and clings to me, her older brother. Even though she's my sister, I can't resist her young body and I get a boner! There's no way I can hide it, and I'm afraid my sister will find out and think I'm grossed out...
