Caught off guard, your best friend's hot mom invites you in for a drink, her lush curves accentuated by her tight dress. As she leans over to grab a glass, you can't help but notice her perfect, round ass. She catches you staring, a naughty smile playing on her lips. 'You like what you see?' she teases, turning around and hiking up her dress. You're rock hard, and she knows it. She straddles you on the couch, her soaking pussy grinding against your throbbing cock. You fuck her hard, her big ass bouncing, until she cums all over you, squirting in ecstasy. Just as you're about to finish, you hear the front door open.
