Lily Larimar and her friend Jewelz Blu are doing their homework on the computer while Lily's stepbrother, Tyler Nixon, hangs out in the same room on his phone. The girls attract Tyler's attention with their giggles and then ask for him to help them out. Eventually Tyler agrees to give them a hand. Coming to sit behind the girls where they're on their knees, Tyler tries to be helpful but instead he's just distracted by the way their asses look beneath their short skirts. Jewelz knows what's up. She lifts her skirt and invites Tyler to get as handsy as he wants while Lily remains oblivious.
Flipping Jewelz's skirt up and pulling her thong aside, Tyler sees his sister's friend is nice and wet for him. Jewelz encourages his attention by grinding her ass against Tyler's hardon. Tyler doesn't need a further invitation. He grabs a fistful of that ass and slides on home as Jewelz tries to hold the moan to keep from alerting Lily. Eventually, Lily does figure out what her friend and stepbro are up to. She doesn't say anything, but Tyler sees her peeking and realizes that Lily is wet, too. He agrees to let Tyler finger bang her as she keeps working on her assignment. When Tyler asks if he can put another in, Lily agrees. Tyler tries to trick her by using his dick instead, but Lily is game to play.
Now that all three of them are in on the fun, there's no reason to be coy. They all start peeling their clothes off as Tyler and Jewelz make out and Tyler keeps Lily's party going with his dick. Jewelz masturbates as she watches the stepsibs in action, keeping her buzz going as she waits for another ride on Tyler's dick. He gives it to her when she hops on the couch and spreads her thighs, diving deep as Lily licks her nipples. Lily gets another chance to enjoy Tyler's charms as she climbs on top of him and takes him deep inside so she can bounce away in a stiffie ride. Now that the girls have had their orgasms, they get on their knees to deliver a double BJ that concludes with Tyler busting a nut in their waiting mouths. The girls enjoy a kiss that lets them share their salty treat.
