You're fucking your first as hard and fast as you can but nothing seems to push you over the edge. You don't hear the door open, you have no idea you're being watched, until you hear a soft moan. Your sister is there, looking hungry and horny and all dolled up from her night out. She's curvy and jiggly and looks good enough to fuck up. Turns out, she wants you just as much as you've secretly wanted her. Keep quite or mom and dad will hear. Take what you want.
