Riley held his breath as his step-sister's skirt inched higher, revealing more of her shapely legs. He couldn't help but imagine what she looked like underneath. Their parents were gone for the weekend, leaving them alone in the house. It was Friday night, and he knew she was supposed to go out with friends but decided to stay home instead. He found out when he accidentally walked in on her getting undressed in her room, exposing her foamy pussy.
She finished tying up her hair and came out of the bathroom, wearing just a tiny bra and panties. She caught him staring and smirked, petting her shaved pussy through her panties. Riley felt his cock twitch in his pants. He couldn't believe what was happening.
Before he could say anything, she moved towards him, pressing her lips against his in a soft, passionate kiss.
