My friend is ravaging my wife's slit

My friend never stops screwing my wife. Every time I'm not at home for work, he comes to give her a cock and use her as he pleases. There are even days when my wife leaves just so he can screw her in his house. To be honest, I don't complain because I love seeing her enjoy another cock, but what I like most is seeing how someone else enjoys and uses her to get off.
