Zac Wild and his girlfriend, Scarlett Bloom, are cuddling on a couch and doting on each other while Kasey Miller, Scarlett's sister, rolls her eyes in the background. The couple are always SO lovey-dovey with each other and it annoys Kasey. Especially since she's attracted to Zac... However, when the couple starts talking about doing a nuru massage, she can't help but to be a little intrigued.The couple parts to get ready for the massage, with Scarlett sending Zac ahead to the bedroom to strip and get ready. 'Don't forget the blindfold!' she playfully reminds Zac, wanting this session to be extra special. But Scarlett's sexy plans are interrupted when she gets an urgent phone call while gathering the massage supplies. As soon as she hangs up, she asks Kasey if she can tell Zac she'll be out for just 20 minutes, which Kasey easily agrees to.Once Scarlett leaves, Kasey curiously picks up the bowl and gel, then grins to herself. She heads to the bedroom, where Zac is already naked and blindfolded on the bed, eagerly waiting for his girlfriend. Kasey mischievously strips down and straddles Zac as she begins the massage, rubbing oil and her gorgeous body all over him. Zac, thinking that he's getting this sensual rubdown from his girlfriend, is in heaven as he urges Kasey for more. She stays as quiet as possible all throughout until she finally can't resist sinking down onto his dick with his encouragement. Once she does, the jig is up as Zac realizes that's not his girlfriend's pussy!Although Kasey's been caught red-handed riding him, Zac is too horny to think straight. Even though she's his girlfriend's sister, they both want to have a happy ending, so they promise they won't utter a word to Scarlett... While this wasn't exactly the extra special session Scarlett had planned for Zac, he enjoys it to the fullest!
