Pulling up her miniskirt to show off her thong, Cielo teases Ricky with her bottom. Then she turns around and pops her titties from her shirt. Eventually, Ricky gets a boner just as Cielo had hoped. He doubles down that he can still control his cum, so Cielo gets on her back and rubs her pussy in an invitation for Ricky to give it to her and show that he's right. Ricky is only human, so with that much urging he's happy enough to stick it into his stepsis.
Cielo climbs on top of him and rides him in cowgirl while rubbing her clit so her orgasm can milk Ricky's shaft. Ricky is feeling pretty confident now, so he gets Cielo up on her hands and knees and fucks her in doggy as Cielo rocks back to meet every stroke. Ricky does manage to hold out for a bit, but eventually he gets too close and knows he needs to pop.
