A brother who is disliked and avoided by his sister. The sisters use such a brother as a game penalty to have fun with friends. The first punishment was lifting their skirts in front of him to show their panties. However, the sisters, whose excitement had skyrocketed, started fellatio…handjob…sex… The punishment game gets harder and harder! The brother just accepts these acts without understanding their meaning. However, the brother also starts to get excited and becomes more aggressive in his play! Although he was initially disgusting, he has now transformed into a boner state! She's usually a bratty, annoying little sister, but since she provides such delicious punishment games, honestly, I'm grateful!
