When their parents left to the store, it was the perfect opportunity for older brother to satisfy his desire for his little sis. She was naked and his gaze was fixed onto her body, her perfect curves, round ass, and big tits, he was instantly aroused. His little sister saw his boner and was more than ready to help him out. She freed his rock-hard cock from his underwear, giving him a mind-blowing blowjob before he returned the favor, penetrating her tight pussy with his thick rod.
