You would never cheat right? I mean, sure during your college days you might have been a bit of a slut and definitely a sizequeen, but you'd never cheat! Right? Your fiancé's been great to you! Sure he might be a bit of an asshole at points but he's normally nice, he buys you a lot of presents and he got you *such* a nice ring for your engagement! I mean it had you squealing when you saw it, the gem was **HUGE**! And he's even good enough in bed! So of course you'd never cheat right?

Unless....

What if there was something better? What if you found a guy who had the **biggest** cock you have ever seen? And what if that cock was attached to your fiancé's nerdy brother? A guy you thought was just some cute nerd or weirdo loser turns out to have the biggest, fattest, *juiciest* cock you have ever seen...

Would you be able to resist? Would you give in instantly and seduce your fiancé's own brother? Would you try to resist? What if you were left alone with him? What if he came onto you?

But of course, you'd never cheat.... Right?

Hey there! A bit of a simpler prompt today but if you can't tell from the little intro there I want to play out a naughty, depraved scene focused heavily on cheating and sizequeen tendencies where a woman ends up cheating on the man she only recently got engaged to! With his own, nerdy, brother! It's an idea I've been obsessed with recently so I decided to make a full prompt for it! The cheating itself combined with who she is cheating with just makes it all so hot!

I'd love to brainstorm a bit with this idea and build the scene up with any partner I have but I'll still give a few ideas for how it could go here! And there are many ways! The two of us could end up alone together for a while for some reason, maybe I'm crashing at your place for a bit whilst my brother is away on a trip? Maybe it's the stereotypical 'snowed in' situation? Or maybe something else completely! Maybe we aren't alone, my brother is around or maybe even more family? Perhaps you and him came over to visit and during all of it you find out, having to figure out a way to get with me behind everyone's back? Or maybe it's a family gathering where you walk in on me changing?

There's a lot of ways this could go and I can easily imagine this being long term or short term!

And to finish off, here is my general list of kinks and limits!

Kinks: Bimbos, Busty Women, PAWGs etc, Slutty Characters, Huge Cocks (Even Unrealistically Huge!), Excessive Cum, Dirty Talk, Cock Worship, Cock Shock, Aheago, Cumplay, Rough Sex, Titfucking, Facefucking, Sloppy/Messy Blowjobs and Facefucks, Public Sex, Cheating, Incest, Interracial, Raceplay, Nationality Play, Lipstick Marks, Makeup Ruining, Onomatopoeia (using stuff like GLRK, GLUCK and SLRP to add extra detail to the scenes, just a personal preference), Power Shifts, Begging for Dick and a few others I can't quite remember right now.

Limits: Vore, Gore, Scat, Piss, Heavy BDSM, Feet and other similar things.
