YSN-484 I jokingly told my sister who was short on cash, 'Lend you money in exchange for watching you masturbate!' Unexpectedly, she immediately started seriously masturbating and tried to make me cum, then demanded money from me.

My sister, even though I'm her younger brother saying this, is beautiful and has a great figure. However, she spends money recklessly, frequents host clubs, gambles, buys expensive items, and then comes to me saying 'I have no money.' This happens every time, so when I jokingly said 'If you show me masturbation, I'll lend you money!' she started seriously masturbating right in front of my eyes. Furthermore, she pushed down the virgin me and skillfully made me cum... If it feels this good, maybe I should lend her money every month!
