Juan Loco walks in on his stepsister Harley Haze and her friend Scarlet Skies having an interesting chat. He tries to insert himself into the conversation, but it just annoys the girls. They dismissively tell Juan that they were talking about how easy it is to get a guy off. Harley looks Juan in the eye and tells him she could get him off in two minutes, which is scandalous to Scarlet but in a really titillating way. It's not long before Scarlet gets Harley to admit that she has sex fantasies about her stepbro. Juan tells the girls that they can't get him to cum. Scarlet and Harley both insist they can.

In a do or die moment, Juan pulls down his pants to reveal his hardon and tells them to prove it. That leaves both girls scrambling for a second, but once they get their bearings they're down to clown. Scarlet pulls out a stopwatch and Harley gets on her knees. When the timer goes, Harley gets to work with her two minute countdown. Her handie fails to deliver, so Scarlet takes a shot at it. She can't make Juan pop in two minutes, either! Now that Juan has stood strong, he tells the girls that it's his turn to try to get them off in two minutes. Harley tries to say her mom is in the next room, but Scarlet is into it and convinces Harley to try.

Getting on the couch and laying side by side, the girls take their shorts off. Juan tugs their thongs aside and goes to work, one hand in each pussy. He manages to succeed as both Scarlet and Harley do their best to hold the moan. When they've come down, the girls decide they should get Juan off for real. They start by sharing Juan's cock in a double blowjob. Scarlet takes the first stiffie ride in reverse cowgirl as Harley helps her out, and then Harley goes for it in cowgirl as Scarlet watches and masturbates. It becomes a true threesome when Scarlet takes a doggy style pussy pounding while feasting n Harley's snatch. Harley takes the last spin on Juan's cock, letting him pump her full of the D until he pulls out and blows his load on her twat.
