Heidi isn't happy that her mum is marrying David's step-dad. She can hear David jerking off through the walls and thinks its disgusting. She wants to know what is so good about it and why he does it three times a day. She asks him to show her and when he refuses she starts stripping off to encourage him. The sight of her amazing G cup tits has him yanking his trousers down and her eyes widen as she sees his huge erection. She talks dirty and begs him to cum all over her ass before laughing at him when he shoots his load on her floor!
