With my friend's cheating boyfriend fucking my big ass

I swore that her boyfriend is a faithful saint, but he's been touching my ass for a long time when she's not seeing him, he also says very provocative things to me, I also like the idea that he wants to fuck me so much but I had to do something to let my friend know what kind of boyfriend he has, so I fucked him, I sucked his big and handed him my huge ass.
