You just let yourself go
Telling a girl to go with the flow is simply a way of telling her that you are going to fuck her. The good thing is that she of course let him do everything he wanted, so it was quite easy for him. There on the couch he began to slowly undress her, she was very excited. Once he could see her pussy, he began to eat it and masturbate her like a bitch, later she ate his cock. He got on top and started fucking her, she certainly liked it. Almost all of the fucking was done with her on top, although almost at the end he put her on all fours so he could take it deep inside her. To do this, he even raised one of his legs, so he was sure it would fit as far as it would go.
In the end the milk was poured on her face, but she was so impressed that she even closed her eyes for fear of that bombardment of milk.
