The lady clearly got on the cock of the sex-starved male! See with what pleasure and strength he fucks her, and besides when they started it was a bright day outside the window, and in the final shots of the video outside the window at night! How many hours in a row did he pull on the lady?
I love a tender and gentle blowjob like that! The lady's tits are great, but her asshole's all flabby and pimply. So it's better to lie on your back during sex, it'll be nicer!
