[HUNTC-514] 'Big Brother Punishment Game' Begins! This is a penalty game where the younger sister and her friend suddenly barge into the room of the older brother, whom he always finds creepy, and suddenly show off his panties! 2 Escalating Further

The older brother is considered creepy and avoided by his younger sister. The sisters use their older brother as a punishment game and get excited with their friends. The first punishment is to lift her skirt and show her panties right in front of her brother. It was something light. But the excited sisters give... Fingering... Sex... And the punishment game content gets tougher and harder! My brother simply accepts those actions, without understanding any meaning. But inside, my brother gets excited too, and his play becomes more and more aggressive! At first, the older brother was creepy and turned into a-and-desire state! Usually a cheeky and annoying little sister, but honestly, I'm grateful that she offers such a delicious punishment game!
