As the water heats up, so do the sisters. One leans back against the cool tile, her sister kneeling before her, parting her thighs to reveal her glistening pussy. She dives in, tongue flicking against her clit, drawing out moans that mingle with the sound of the shower. The standing sister grips her own breasts, pinching her nipples as she watches, her body writhing with pleasure. They switch places, their bodies sliding against each other, their hunger insatiable until they both reach their climax, gasping and shuddering in each other's arms.
