Alex Coal goes above and beyond for her stepbrother, Jay Romero, particularly in light of the recent wrist injury. Lilly Bell, one of Alex's friends, finds it really strange that Alex helps Jay so much. Lilly can't help but believe that Alex's desire to look after Jay isn't the only thing going on between the stepsiblings. When Alex gives Jay a bath and then chases Lilly away so she can give him a bath, Lilly becomes even more suspicious. Lilly interrupts Alex as she is about to really soap Jay's dick up, saying she knew there was more going on between the stepsibs. Lilly won't have it, even when Alex insists there isn't. She gives Jay a hardon by flashing her tits. Alex is not amused by this, as he feels that Lilly is now putting in more work. The stepsiblings go to the bedroom, where Alex begins to pet Jay, taking care of his needs while keeping him from having to think about anything unpleasant. She begins sucking Jay's cock since it causes him to climax more quickly. Lilly's reaction to seeing Alex suck her stepbrother off surprises her a little. She begins massaging her crotch before declaring that she can get Jay off more quickly. Lilly makes it a competition by pushing Alex aside. Lilly can't win, so Alex pushes her way back in to set up a double BJ.Since Jay hasn't climaxed yet, Alex coaxes him into lying down on the bed so she can go on his dick and cowgirl-ride him in reverse. Lilly finds it hot enough to finger bang herself while watching, even though she insists it's still just business. When Alex approaches to kneel in front of Lilly so he can slam it in, she gets to experience his dick next. Alex seizes the chance to have a different kind of ride by climbing inside Lilly's mouth. As she feasts on Lilly's snatch, Alex gets down on her hands and knees and enjoys a pussy pounding in the dog. To ensure Lilly receives the same treatment, the girls trade places. Just before pulling out and cums all over Lilly's ass and Alex's face, Jay manages to satisfy Lilly. As long as Lilly can assist, she swears not to tell anyone how Alex looks after her stepbrother.
