Molly Little and her best friend Jade Maris have figured out how to make exercise fun. They've attached dildos to their bikes and cut holes in their bike shorts. They're really enjoying their workout when Molly's stepbrother Jodie Johnson begins staring at them. Jodie tries to make conversation, but the girls mock him until he leaves.

Jodie returns when the dildo bikes have gotten the girls moaning so loud that they can't contain it anymore. Now that their horniness has overwhelmed them, Molly talks shit about whether her stepbrother is going to just watch or actually come in and fuck them. She doesn't have to ask again. He comes up behind the girls and sticks into them in turn, first dicking Molly down as she rides and then giving Jade the same treatment.

Hopping off the bikes, the girls go for a blowjob that lets them each suck Jodie's cock and balls with enthusiastic glee. They sit Jodie down on the couch so that Jade can ride him in reverse cowgirl before she swaps out with Molly. Then Jade gets on her back so Molly can ride her tongue while Jodie dips his dick between her thighs. Molly is right there as Jade pulls out to cum all over her BFF, licking the jizz from Jade's stomach and sharing it with her in a deep cummy kiss.
