Tristan Summers and her friend Madison Summers are just chilling in Tristan’s room and enjoying themselves reading all the Valentine’s cards they’ve each received. When Kyle Mason, Tristan’s stepbrother, comes in to give both girls his own Valentine’s gifts, Madison is just floored. She really wishes she had a brother that would be that nice to her. Tristan has been noticing how much Kyle dotes on her and she has come up with an idea that she thinks Madison might like. Working together, the girls make up a “Free Use” coupon that Madison then gives to Kyle as a Valentine’s gift. She tells Kyle he has to cash it in within the week, though.Kyle hangs on to his gift for a few days, then waits until Madison is over hanging out with Tristan again. The girls are just making popcorn to watch a movie when Kyle approaches Tristan with the card. Tristan is happy to comply. Kyle begins by asking if he can get his hands on Tristan’s big tits, which she happily allows. Madison is initially happy to eat some popcorn and watch the show as Kyle gets the green light to go lower and tug his stepsister’s thong aside so he can rub her pussy. When Kyle makes a move to whip the D out to fuck Tristan, though, she makes him pause just long enough to lead him to the couch and make it clear he has to pleasure Madison as part of the deal, too. How could Kyle say no to that?At first, Tristan keeps Kyle all to herself as she licks him like her favorite lollipop. Eventually, though, she beckons for Madison to join her. The girls share beautifully in a double BJ, but Tristan is the first to get to climb aboard for a stiffie ride as Madison lays back and masturbates as she watches. The girls swap spots, with Madison going for it in reverse cowgirl as Tristan diddles her clit. Getting on her knees, Madison mewls with delight as Kyle does her in doggy. She eventually muffles her moans by feasting on her busty BFF’s dripping twat. Already on her back, Tristan easily slides forward so that Madison can cradle her shoulders and watch as Kyle fucks her in missionary and then gluts her with a holiday creampie.
