My niece, Mai, was going to stay at my place for a while during her tennis club trip. As I watched her sleep on the couch, her erotic ass peeking out from underneath her sportswear, I couldn't resist any longer and started jerking off. When she noticed what I was doing, she tried to call home, but I quickly stopped her. Oh shit! If things go like this, my life might just end here... Unable to resist anymore, I pounced on Mai's irresistible ass!
