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.
He was a modest guy, and his sister took him and corrupted him, made him lick her, and in return she did not even take his dick in her mouth, just masturbated him and he cum copiously. But her cum is arousing. So she squirted just from the toy. It's a good thing she didn't put it in her brother's mouth, or he wouldn't have realized it at first. But I think she will teach him all the positions and he will become a professional cunnilingus.
