In a twisted game of one-sided phone sex, Diana Grace unknowingly becomes the center of her daughter's depraved fantasy. Sheena Ryder, the insatiable stepdaughter, watches her mother's body language, the subtle shifts and gasps, as she teases her pussy with expert fingers and a ravenous tongue. Diana's voice quivers, her words faltering as Sheena's relentless assault on her clit brings her close to orgasm. The tension between Diana's conversation and the illicit pleasure she's experiencing is almost too much to bear. Sheena, however, has no mercy, intent on making her mother cum while she's still on the call.
