What would her son do without his mother. She teaches his girlfriend how to properly please her son. It all starts with a gentle sucking of the cock. Then it goes into a deep throat blowjob. And then the fucking begins in all positions. Missionary. Going in from behind doggy-style. Bouncing on the dick from above. Girlfriend's as flexible as a twig. Bends well in all directions. And moans with pleasure. But the whole video does not leave the thought of when to fuck the mother already.
In fact, it's a proven fact. No one would refuse such a training session on boxing, see how she was furiously sucking his big dick, and she seems to be enjoying it as well. In general I think that such a fuck will be a norm for them now, because they are unlikely to stop at the received emotions, they will want more and more, and there more and more, we just have to watch.
