Riley is horny all the time. seriously, ALL the time. She loves to use her Hitachi to get herself off. Her older brother heard the noise of it vibrating and peered through her door. He saw his younger sister on the bed bare ass naked, moaning with nothing on except her favorite rainbow socks. He couldn't resist stroking his cock as he watched. Without her noticing he strips his clothes off and lies beside her in bed. Shocked she asks "What are you doing"? He tells her "You're getting off so why not help your brother out"? She stares at his hard cock and quickly agrees.Can Riley multi-task and get her and her big brother off before mom gets home? I guess we'll see..
