Naive Girlfriend Cheats With Bully

My boyfriend has been coming home depressed, I fuck and suck and ride him back to a happy mood, but I can't stand that he hates going to work now.
Turns out he's being bullied at work, so I'm going to solve this problem, I invite his bully and I'm gonna make him stop.
I figure out he started bullying my boyfriend after the corporate get together where I met this guy for the first time.
He's bullying my boyfriend because he's jealous of him. I start showing off what he's missing out on because he's such a jerk. He could've had a girl like me, could've been receiving amazing blowjobs, if he was nicer.
When he says my head game is probably weak, I'm not gonna take that, I'm not gonna be bullied by him. I'll just have to prove how amazing I am.
Okay, he's a lot bigger than my boyfriend, but I'll show him how good I suck cock. Though as I start blowing him and trying to take it down my throat I realize this is way harder.
After I suck his cock for a while he admits that I'm pretty good, but says that sex with me has to be boring.
Ugh this guy, guess I'll just have to prove him wrong. I straddle him, taking my tits out, and letting him know that my boyfriend gets to do this all the time.
Of course now he just has to say that I can't even twerk on his dick, He has a big dick and he is a big dick. So I show him that he's wrong.
I get down on all fours and as he starts to fuck me, I admit he fucks me much better than my boyfriend does.
I remind the bully that my boyfriend gets to fuck me whenever he wants, but this just gets him to pound me harder, working me closer to orgasm.
As I'm cumming on his cock I can feel him cumming deep inside me. What the fuck. I didn't say he could do that.
Oh well, as long as he's learned his lesson, otherwise I'll just have to keep inviting him over until he does.
