Blonde milf gets involved in fucking

Imagine you come home after a long and tiring day. You take off your clothes and get into bed, but you just can't fall asleep. Then you hear noises from the next room. A moan and a soft laugh. You get up and go to the door. The sounds get louder and you realize it's your neighbor having fun with her boyfriend. You peek through the crack in the door and see him fucking her passionately. Her eyes meet yours and she smiles as she continues to ride his cock. Then she opens the door and lets you in.
