MIAA-112 I can't relax even for a second! - Touka Rinne, a busty slutty older sister who takes advantage of the moment when her younger sister is gone, whispers to her younger sister's boyfriend and cuckolds her.

If she leaves her seat even for a moment, the older sister will become a slut! - When shopping, going to the toilet, taking a bath, you can reach your crotch in every situation! - Even though I think I might get caught, I end up getting caught every time. - The older sister's time-saving sleeping technique is too amazing! - Every time she leaves my seat, I get a tingle in my crotch, and I'm looking forward to seeing how she'll treat me as a slut this time. She's a woman's enemy, but from a man's point of view, she's an erotic god! - Even though I think it's bad for her, I'm defeated by the eroticism of the older sister!
