Minxx Marii and her boyfriend Robby Echo have been together for long enough that the sex is comfortable and fun, but not necessarily new and exciting any longer. They're just getting hot and heavy with one another when Minxx's new roommate, Aubree Valentine, decides to both help them spice things up and get a piece of the action for herself. She waits for Robby to finish eating Minxx out and get on his back with Minxx blowing him, then she makes her move.Putting a finger to her lips to keep Robby from speaking up, Aubree sneaks into the room wearing just a sheer bra and matching panties. Getting on her knees behind where Minxx is kneeling, Aubree leans in and laps at her roommate's dripping twat. Minxx is surprised, but she finds it surprisingly hot when she realizes what's happening. After a few moments of discussion, the girls agree to get together and share Robby's cock, much to Robby's delight.After sealing the deal with a kiss, Minxx and Aubree climb into bed together and flank Robby, with one girl kneeling on either side of his hips. Using their hands and mouths, they demonstrate how nicely they can share by sucking and stroking together. Taking turns just gets both girls even hotter for each other, and soon they can't keep their hands off one another any more than they can keep their hands and mouths off of Robby.Robby continues to lay on the bed and let the girls have their way with him as they work out how to fuck him best. Minxx climbs onto Robby's hardon and begins rocking her hips in cowgirl. Meanwhile, Aubree settles her twat on Robby's face and rides his tongue as Minxx works herself into a big climax.Aubree gets to sample the D next as she gets on her knees between Minxx's thighs. Even as Aubree leans forward to eat her roommie out, Robby glides home into her velvet glove. Going deep, Robby makes Aubree squeal even as she gives Minxx the same favor.Minxx winds up on her back with Robby banging her and Aubree rubbing her clit against Minxx's tongue. Watching his girlfriend and her roommate get it on like that brings Robby right to the brink of his control. Pulling out, he nuts all over Minxx's belly, leaving a puddle for Aubree to run her fingers through as the roommates bask in the afterglow of their newfound sexual relationship.
