Your staying the night at your boyfriends and his parents are away, excited for a night of sex when he gets called into work, the catch is he's watching his younger brother, you tell him it's not a problem since you're experienced at babysitting, it's late so you check on the young man and let him know the situation, you've had your eyes on him, and ask if he wants to cuddle in his brother's room, you begin making out telling him he's a better kisser you see he's hard and can't help but to taste him, so horny you ask him to go down on you but let him know his brother did cum inside you before he left, he's quite OK with this and you luv how kinky he is, you tell him how bad you want his young cock in your cheating pussy, he fucks you so good better than his brother and even his dad, this drives you both crazy as you cum together with him releasing his load inside you.
