Elena, lounging on the bed, feels an unexpected sensation against her friend's pussy. As she looks up, she's met with a sight that leaves her breathless - her friend's lover, still in socks, is fucking her friend from behind. Elena's eyes widen as she takes in the sight of the hard cock sliding in and out, her friend's wetness glistening. She watches, frozen, as her friend's body responds, tits bouncing with each thrust.
