Natalie Knight has noticed that her adopted sister Emma Starletto and their half-brother Codey Steele have a very close relationship. She suspects that they are more than friends. He brings Natalie a gift for Valentine’s Day as they lounge around the room together: dick candy and anal plugs with his cock hidden deep inside. Natalie is a little hesitant to do anything with Codey’s gift since Emma is there, but eventually Codey persuades her to give him a handjob. Once Natalie gets her hands on Codey’s cock, she knows she’s going to suck it. She continues until Emma notices Emma blows up her stepbrother and loses her shit! Codey tells Emma her panic is exactly the reason they didn’t include her in their Valentine’s Day club and storms off.
Later, Emma and Natalie walk into Codey’s room hand in hand so Natalie can tell Codey that Emma wants to join the Valentine’s Day club. Codey is reluctant at first because he thinks Emma will eliminate them, but Emma just wants to be included. He decides that the foster sisters should start kissing while he watches so he can assess Emma’s sincerity. Codey is still not convinced after this demo, so he tells Emma that before she can join her she has to watch him kiss Natalie and make her suck his cock without looking back. Emma gets away with it, and soon Natalie got Emma to have a taste of Codey’s fuck stick as well.
Turning around, Natalie pulls up her pajama shirt so Codey can put it on from behind. This upsets Emma, but Natalie is determined to form a happy family. She brings Emma closer so she can eat her while Codey fucks her doggy style again. Next, Natalie helps Emma overcome her fears as Codey creeps inside her for the first time. Soon Emma realizes that there is nothing to worry about and Codey’s fuck stick feels great! Once Natalie knows Emma is engaged, she sits down with her pussy over Emma’s mouth so Emma can be fully included in the middle of a sibling sandwich. Natalie and Emma then swap places, Emma testing Natalie’s mouth as a cowgirl and reverse cowgirl as Codey rolls Natalie’s party. Then Emma does another round on the D, this time doggy style as her adopted stepbrother brings her to orgasm. There is only one last step before Emma’s formal initiation into the Valentine’s Club. She and Natalie make Codey work with their hands and mouth until he rewards them with a double facial flowing in their mouths.
