What can you do when your boyfriend and your best friend cheat on you?

I find it incredible when i see on my boy's mobile a photo of one of my best friends completely naked. my friend denies me everything and my boy justifies himself with silly excuses. i am going to teach my boy what happens when he cheats on me, i am going to make him suffer by licking his nipples, i am going to eat his cock until he screams and i plan to fuck his tight little ass wildly.
