[F4M] Ruining your rival by destroying his sister.

NSFW

To say that Zain was respected would be an understatement. In some circles, people practically worshipped the ground he walked on. Those same people wouldn't give you a second look even if you bumped into them. That had always pissed you off. Always. The way you saw it, there wasn't much of a difference between you and him. A few percentage points on a few tests? So, what if your thesis wasn't "groundbreaking" or whatever? It was bullshit.

It was also a one-sided rivalry, and you knew it. Hell, Zain didn't even consider you a rival. He just thought of you as a strange acquaintance. What could be more humiliating than that?

Yet your anger had never faded. Even as he overtook you in life. Even as you became just another Professor at the College he was a damn department head at. There had to be something.

God answered your prayers.

You found out he had a sister. Not just any sister, but a gorgeous sister with a fat ass. If that wasn't enough, apparently you might even get the chance to meet her soon. There was even some talk of her joining the campus as a Professor!

Apparently, she was almost as smart as Zain himself was. That didn't matter. You knew the perfect way to both destroy Zain and reclaim all the glory you deserved.

You just had to get your giant cock into her asshole and make her squeal. You didn't know how long that would take, but you would make it happen.

Thanks for reading! This is meant to be a more manipulation and corruption focused role, rather than a cnc/blackmail one. This is also meant to be a very detailed role, so do keep that in mind.

This role is also pretty open-ended, so I'd love to discuss it in a lot of detail before we start. One question is:

1: How do you even find out about this sister? Maybe you see her and realize after the fact. Maybe you trick Zain into revealing she exists. Maybe you stalk him on your own and discover her.

If you can come up with fun plotting and worldbuilding questions like this, then we're going to have a great time.

I'm looking forward to building on this with someone!
