Filling In At The Last Minute

Dee wanted River out of the house. Fast. She had a night planned with her husband, and the last thing she needed was her stepdaughter hanging around. River said fine, she'd stay in her room. Ten minutes later she got a text: he wasn't coming home. River headed back to tell Dee, swung the bedroom door open, and froze. Dee was on the bed in black lace, blindfold on, tits spilling out, waiting like a gift. She heard the door, figured it was her man, and purred for him to come fuck her. River stepped inside. Dee reached out, grabbed River's wrist, pulled her close, and slid River's hand straight between her legs. River felt how wet she already was, heard Dee moan, and didn't stop. Fingers sank in deep while Dee arched, tits bouncing, still thinking her husband was the one working her open. River kept going, pumping harder, thumb rubbing her clit until Dee came hard, gasping and shaking, completely unaware it was her stepdaughter making her drip.
