Step siblings Alex Coal and Codey Steele have been getting it on in what they think is secret. They are getting it on when Alex's Mom, Artemesia Love, comes home with some takeout. The stepsibs believe that they've kept their secret, but they were definitely loud enough for Artemesia to know what they were up to. She decides to play a trick on them and tell the stepsiblings that they're actually cousins. Horrified, Alex and Codey wait until Aretmesia leaves and then agree they can never bone down again.
The stepsiblings really intend to stick to their promise to not get it on, but later Alex joins Codey in bed saying that it's too cold in her room to sleep. Codey agrees to spoon with her just this one last time, but Alex starts rubbing her ass against his morning wood. They both get flashbacks of all the times they've gotten together, and Alex gets Codey to agree to do it one more time. On her knees, she mewls in delight as Codey pulls off her panties and sticks it in. They do it in doggy, but Alex isn't going to be satisfied with just one position.
Alex urges Codey onto the bed so she can slide down on his fuck stick and kick off a stiffie ride. Her moans of delight are long and loud as she bounces away on her personal toy. This position is one of Alex's favorites since Codey can knead her tits and rub down her clit to make sure she cums. As soon as she has come down from her orgasmic high, she rolls onto her back and spreads herself wide open for Codey to dive deep. They've been together so often that Codey knows just what his stepsis needs. As she cums around him, Codey shoves deep and gives her a creampie. Alex freaks out that he came inside her, and the noise brings Artemesia in. She reveals that she was joking about them being related, but then demands to know what they're doing getting it on when they're still step siblings.
