Codey Steel has been daydreaming about his stepsister's Emma Starletto's BFF for a long time. Eventually, when Codey wanders into the kitchen to see Emma hanging out with Lilly Bell, he can't help but daydream about the sexy possibilities. Emma isn't very nice as she snaps Codey out of it, but later he tries to make nice by asking her to help him hook up with Lilly. Emma agrees to put in a good word for Codey, but only if she can watch them fuck if he manages to seal the deal. Codey doesn't think Emma is serious, but he agrees to her terms.

A month later, Emma is certain that Lilly and Codey have been hooking up. She decides to collect on their bargain by snooping when they go to the bedroom together. Lilly doesn't spot Emma, but Codey does. He tries to get Emma to go away as Lilly sucks him off. Instead, Emma just unsnaps her shorts so she can diddle herself as she watches her BFF blow her stepbro. When Lilly sits up and then impales herself on Codey's fuck stick to start riding, Emma slinks into the room. Lilly is still oblivious to Emma's presence as Emma begins licking Codey's balls. When Lilly finally catches on to what's happening, she's eager to invite Emma to join in for a stepsibling threesome.

The girls seal the deal with a kiss, and then Lilly climbs off the D so that Emma can enjoy Codey's nice cock. Lilly gets another go when she gets on her knees to have Codey fuck her in doggy, a position that makes it easy for her to go muff diving for Emma's sweet juices. Scooting forward, Emma spreads her thighs for Codey to go to town fucking her. Meanwhile, Lilly climbs on top of Emma's mouth to ride her bestie's face. Lilly hops off as Codey shoves deep and gluts Emma with a big creampie, then leans forward to lap the salty treat from Emma's cooch and snowball it with Emma.
