Part 3 of the making you cheat on your gf series! 
So, me your insanely hot, addicted to your cock neighbor; is throwing a holiday party and invited a bunch of people including you and your hot girlfriend. You have a few drinks and you notice me eyeing you from down a hall to the bedrooms. You sneak away and I convince you to come "see something" in this room with me. You tell me we shouldn't do this it's too risky but I get pouty and threaten to tell your gf if you don't fuck me right here and now! Your dick decides for you, once I start taking off my clothes you just want to suck on my huge tits again. I talk about how much huger my tits are than your gf's and how jealous she would be if she caught us! You see how wet and hungry my pussy is and you can't help but bury your horny cock into it, so eager to fill me with your cum. I start riding you, dangling my huge tits in your face, it feels so good but you're afraid someone will walk in and see me riding the fuck out of your hard cock. I start riding harder making the bed squeak! You're hoping your gf won't hear it but at this point you don't care that much because my body feels so fucking good. I cum hard on your dick trying not to be too loud, and then turn around and start riding you in reverse. The sight of my bubble butt bouncing up and down on you sends you over the edge as I'm telling you to pump me full of cum! We quickly get dressed and go back to the party unnoticed.
Lot's of dirty talk about cheating, being obsessed with your cock, talking about your gf and the possibility of getting caught, bed does squeak a bit loud but not too much, also no actual creampie just implied.
