This has to be one of the most beautiful videos I have seen. She gets aroused by his oral and starts squeezing her breasts. His hands reach up and replace hers on her breast and she lovingly puts her hand on his head and also to make sure he stays there. He squeezes her breast as she also squeezes her. her arousal increases and you can see when she starts to cum. The best part for me was when she bent over him and embraced him.
That is what sex is all about. The union of two people who know how to give each other happiness :-)
