Stepsisters Zoey Foxx and Gia Derza are hanging out in their living room, talking about their next test for a massage certification course they're taking, and what area of the body they've been focusing on. While Gia talks about how she enjoys massaging the legs because of all the muscles and bone density, Zoey retorts that her favorite part is the back because it's so strong and fragile at the same time. They both receive a text at the same time. Gia picks up her phone and tells her sister that her friend canceled. Zoey responds that her friend canceled too and now they have no one to practice on.After a second, Gia has an idea. Maybe they could practice on...each other? Zoey feels a little weird about it since they're sisters but Gia reminds her that they're just step-sisters and anyway, they don't have time to find replacements to practice on. Zoey agrees and they set up the table. When Zoey asks who should go first, Gia suggests that Zoey take off her clothes and lie down. Zoey takes off her clothes and lies down on the table as Gia oils up her hands and starts working on her. Gia rubs her sister down and wastes no time in working her way down to Zoey's plump ass. When Zoey asks if she should be doing that, Gia tells her that there seems to be a lot of stress in that area. Zoey agrees that there is a lot of stress there and gives Gia the go-ahead, who slathers oil on Zoey's juicy ass. As Gia works her glistening bottom, Zoey begins to gasp with enjoyment. But, feeling like she may be enjoying this massage a little TOO much, Zoey abruptly suggests that she turn over. Gia begins massaging Zoey's breasts, and it isn't long before her hand creeps down to Zoey's pussy. Zoey stops Gia, saying that she shouldn't be doing that. Gia isn't sure what the big deal is. Zoey says that if it's really no big deal, then why doesn't she lie on the table and let Zoey massage her? Gia eagerly agrees and takes off her clothes, lying down on the table.Zoey moves her hands on her stepsister's beautiful body and finds herself enjoying it more than she anticipated. Zoey's not the only one enjoying it, and Gia tells her so, commenting that Zoey is very good with her hands. Zoey thanks her, turning her attention to Gia's ass, pouring oil on it as she lovingly squeezes it. Gia is in heaven but mentions that there's an even better angle to relieve tension. She flips over onto her back, spreading her legs wide and exposing her shaved pussy invitingly. Zoey can definitely take a hint and lowers her face between her sister's legs, gently licking her pussy. She can't handle it for long, and as Zoey flicks her clit with her tongue ring, Gia cums, screaming in ecstasy. But their practice session is far from over, and these two sisters are about to learn much more than any massage class could ever teach them.
