In the dimly lit living room, Alli Rae and her stepbrother, David Loso, share a bottle of wine, their parents still out. Alli, tipsy and bold, asks David about his "biggest fantasy." David, hesitant at first, admits his curiosity about her. Alli, grinning, stands up, letting her robe fall open, revealing her naked body. She straddles David, grinding on his lap. David, hard and eager, lifts Alli up, impaling her on his cock. They fuck wildly, the sound of their bodies slapping together filling the room. Alli comes first, her pussy tightening around David's cock. David follows, pulling out and coming on Alli's stomach, their taboo act complete.
