Movie description: "She's Got My Back". Two friends, Serene Siren and Lexi Luna, are having fun hanging out when Lexi suddenly winces. Lexi explains that she has a knot in her shoulder that hurts if she moves too fast. Serene offers to help by massaging her shoulder, and Lexi gratefully accepts. As Serene massages Lexi's sore shoulder, Lexi says that Serene's touch feels SO good. Lexi then says that the pain is actually in BOTH of her shoulders. Serene is happy to help, so she starts massaging both of Lexi's shoulders. Lexi then claims that the pain has moved further down her back, so Serene starts massaging down Lexi's back, until Serene reaches Lexi's hips. They agree that massaging Lexi this much would be easier on a bed, so they get up and go to Lexi's bedroom. Lexi strips down before getting onto the bed, which catches Serene by surprise, but Lexi points out it's not really a big deal, since they've been friends for so long. Serene admits that's a good point, and starts giving Lexi a more thorough massage using some oil that Lexi conveniently had in her room. Serene massages Lexi's naked body all over, including her breasts, and they both become increasingly aroused. Lexi then kisses Serene, who by this point is open to the idea of taking things further...
