Description: Natasha Nice and her stepbrother Brad Sterling are bored as they hang out on the couch. Eventually, Natasha asks if Brad has heard of the Sis Challenge that's going around online. Brad hasn't, so Natasha explains that they both get naked and if Brad pops a boner then he loses and is a freak. Brad is certain that he can control his impulses, so they get naked together. Indeed, his dick is soft even at the sight of his sister's lush curves and massive titties. Natasha isn't about to accept her loss, so she wiggles her TA until he gives her the hardon she's after. Things escalate when Natasha confesses that she's never seen an erection in real life and then asks if she can touch Brad's. He agrees, but instead of touching him she accidentally starts stroking. Brad hangs on for as long as he can without letting Natasha know, but eventually his moan gives him away. She tries to disengage, but Brad confesses that he thinks she's hot. Natasha is a little bit shy, but she tells Brad that her pussy is wet. He takes the opportunity to lay Natasha down on the couch and bury his fingers and then his face between her thighs. Having Brad finger banging her is great, but what Natasha really wants is the D. She urges Brad to shove it in as she gropes her own bountiful chest. Then she gets down on her knees to suck him off and give him a titty fuck. Brad sits down on the couch and lets his sister ride his hardon, but things are much more fun for both of them when Brad delivers a hard and fast doggy style pussy pounding. His sis is so hot that Brad can't help but blow his load inside her for a creampie that leaves her dripping cum.
