Teen Natalie Knight has noticed that her Emma Starletto and their stepbrother Codey Steele have a very close relationship. She suspects that they're more than friends. 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 believes Emma will rat them out, but Emma just wants to be included. He decides that the should start kissing while he watches so he can gauge Emma's sincerity. Codey is still not convinced after that display, so he tells Emma that before she can join in she needs to watch him kiss Natalie and have her suck his dick without flipping out. Emma makes it through, and soon Natalie has tugged Emma in to take a taste of Codey's fuck stick, too.
