Marley Brinx and her stepbrother Alex D. have a video channel. Today their video is the Touch My Body Challenge, where you blindfold your partner and have them guess what part of your body they're touching. Marley and Alex take turns, eventually upping the ante so they're using mouths instead of fingers. Marley pranks Alex with a dildo, and in return he whips out his fuck stick for her to suck.
To get Alex back, Marley sticks her little finger in her ass and then puts it in Alex's mouth so he can suck her stinky pinky. Alex sticks his tongue in Marley's mouth so she can taste her own stink, and soon they're making out while Alex rubs Marley's twat. Like putty in Alex's hands, Marley lets her stepbrother finger bang her creamy twat before agreeing to put the blindfold back on one last time. Alex takes that opportunity to start fucking her.
Marley protests at first, but soon the stepsiblings are going at it like rabbits. Marley takes some time to suck Alex off for real before getting on her hands and knees to take him deep in her juicy twat from behind. Once she finishes herself off by riding Alex's fuck stick, Alex gets the last laugh by letting loose a creampie of jizz in Marley's hairy snatch.
