Rob Carpenter has a serious sex addiction problem that has him jerking off in all kinds of unexpected places around the house and leaving cum surprises for his stepsister Chloe Cherry to find. When Chloe steps out of the shower and finds jizz in her towel, she confronts Rob about his predilections. When she reaches his room to find him jacking it with a pair of her panties! In desperation, Chloe offers to give him a handie if he'll agree to stop leaving salty surprises everywhere. Rob does agree, but when Chloe's hands can't get him off he demands her hot little mouth instead. That finally does the trick, and Chloe even does the favor of swallowing Rob's cumshot. It's too bad for Chloe that Rob doesn't keep his end of the deal. When she finds that he has jacked off into her pajama bottoms, she offers to actually fuck him this one time if he'll go to counseling for his sex addiction. Rob has been longing for his stepsister's pussy wrapped around his dick forever, so he agrees. He soon finds himself buried balls deep in Chloe's greedy snatch, with her breathy moans of delight acting as music to his ears. He can't hold back as he fills her soft twat with a creampie of cum, much to Chloe's surprise and dismay.A few weeks later, Chloe seeks Rob out in his room. He's defensive at first since he's been going to counseling as agreed and hasn't slipped up, but Chloe bashfully confesses that maybe he's not the only sex addict in the house. Rob isn't about to turn down his stepsister's offer for another go, and soon he is happily paddling away at her as she kneels face down on the bed. When Chloe rides Rob to climax, he does her the favor of pulling out this time to cover her muff in jizz.
