Stepsiblings Lucky Fae and Kyler Quinn have a little brother who needs a babysitter. Lily Larimar is the new sitter, and as soon as Lucky walks in he begins to hit on her. There's an obvious attraction between Lily and Lucky as they set up a date for later on. Before they can finish chatting, though, Kyler walks in and wants to know what's going on. Lily leaves to go prepare a bottle for her charge since the jealousy oozing from Kyler is obvious. Once she's alone with Lucky, Kyler puts out there that her stepbrother doesn't have to look to the babysitter to get some.
Later, Kyler walks into the living room to find Lucky and Lily making out. She responds by announcing that she's doing laundry and she needs Lucky's pants. Dropping to her knees, she pulls Lucky's pants down to expose his big boner. Lily claims Kyler only did that to get to the dick first, which Kyler doesn't deny. Not one to go down without a fight, Lily pulls her shirt down while saying she thinks her tits are nicer. Kyler tugs her shirt down to try proving Lily wrong, which gives Lily the chance to take over sucking Lucky off. Kyler isn't about to give up her BJ, but she's at least willing to share with Lily.
When Lily escalates things by climbing onto Lucky's lap and sinking down for a reverse cowgirl stiffie ride, Kyler initially pouts. It's actually really hot to watch the babysitter ride her stepbrother, though, which leads Kyler to eventually begin flicking her clit and finger fucking her pussy. Lily notices and cedes the D to Kyler so she can go for a reverse cowgirl ride of her own. When it's Lily's turn again, she gets on her back so Lucky can dick her down on the couch. Kyler opens her thighs for the exact same treatment as Lily takes the opportunity to climb on top of Kyler's face for a full on threesome. Lucky keeps it up until he's sure both girls are satisfied, at which point they share him one last time until he pops into both their open mouths.
