When stepdad comes back home earlier, he bumps into the girls chilling by the pool. They are getting ready for the pool party and ask what he thinks about their outfits. Eva sees that he has caught their bikini vibe and his dick is becoming hard rock. Girls start flirting, flashing their tits and wiggling firm asses. Since Eva loves showing off, they propose a kind of challenge to see who cums first while masturbating. Her stepdad is confused but at the same time there is no reason at all to pass up such an amazing opportunity. Their long legs and tight asses are nice, but it is their perky breasts that really grab his attention. Seeing them play with their nipples and pull their bottoms aside to expose their wet pussies is too much for him. But all they want is to watch him taking out his cock and enjoying himself while they are playing with each other. With their legs in the air, the girls finger themselves in turns, watching stepdaddy pumping his throbbing tool. Stroking it faster he watches them, waiting to see who cums first. He can no longer hold it and shoots his load while Mandy cums. This time the girls won the challenge, but next time they will let stepdad fuck them in turns.
