Alexis Fawx and Penny Pax are both engaged in a yoga routine with Alexis leading the way. Penny is having trouble keeping up with Alexis but tries her best, following her into poses such as downward dog. The various poses lead to them showing off their bodies, but especially their sexy butts!Meanwhile, Kira Noir has a perfect view of those tight butts through their tight yoga pants. She doesn't say anything but sneaks looks now and again. Who could possibly resist the temptation?Then Alexis pauses the routine and breaks out a rose quartz healing crystal, mentioning to Penny how good it is for the whole yoga and meditation process. It's all about self-love, after all! Maybe so, but Penny's more interested in if its mystical powers will help her butt get bigger. Alexis cheekily runs a hand over her own butt and says it's worth giving it a try -- look what it's done for her!Penny is not convinced, even as Alexis does squats in front of her to show off that butt. It's just the yoga pants making Alexis' butt look big. Alexis exclaims that yoga pants can't do that and wants Penny to take a closer look. They both get distracted from their yoga routine as they compare butts, wondering whose is bigger and firmer. They even slap their butts to test said firmness, which really gets Kira's attention.They are going nowhere fast, so Penny invites Kira over to be the judge. Kira eagerly slides in behind them as Alexis and Penny go down onto their hands and knees, ready for the inspection. Of course, Kira takes her time when choosing which butt looks better -- there are a lot of things to consider, obviously! She's aroused by both of them as they both vie for her vote.Kira says it's hard to tell who is the ultimate winner because they're wearing yoga pants. Penny then throws out there that she's game for naked yoga, which Kira insists is good for the chakras. Since Alexis and Penny were just talking about healing energies, their attention is drawn back to the healing crystal. Penny suggest that whoever can hold the crystal between their butt cheeks obviously has the bigger butt.Kira picks up the crystal, marveling over it and how its vibrations speak to her. She then asks Alexis how best to absorb the healing powers of the crystal, which Alexis responds that its by holding the crystal close to you. Kira asks if Alexis ever tried to absorb its power internally and she says, oh yeah, all the time! Penny then volunteers, wanting to have this experience firsthand.Instead of trying to hold the crystal between their butt cheeks, they instead make a contest out of who can take the crystal deeper inside them. Of course, the girls can't help having a little extra fun by eating each other's pussies out at the same time. Surely this will somehow prove once and for all who has the biggest butt.
