Mistress' Sissy

“I appreciate you wanting to help, but I don’t exactly see how this is better.”

“It’s simple, babe! That mean old bully can’t beat you up anymore if he’s completely drained from fucking me!”

“I get that, but he fucks you a lot…”

“Well, bullies often have a lot of stamina. Don’t worry, sweetie, I’m sure before long he’ll get bored and just move on!”

Unfortunately for Fred, the bully did not get bored nor did he move on. If anything, he reveled in his new role as a bull and was quite keen to explore this cuckolding relationship! It wasn’t long before he stopped calling Fred’s girlfriend “my slut” and started referring to her as “our girlfriend.”

Shortly thereafter, the bully introduced a “cuck tax” that Fred had to pay him each month to retain sexual access to their girlfriend. It seemed a lot, especially since he’d already been reduced to scraps (disinterested handjobs and the occasional sloppy seconds.) However, their girlfriend encouraged him to go along with it to keep the peace.

Fred decided he finally had enough when the bully took their girlfriend out of town on a surprise weekend getaway to celebrate their cuckolding anniversary. He was going to confront him about this shared girlfriend nonsense and his ridiculous cuck tax as soon as they got back!

But he’d never get the chance.

He’d just finished masturbating to an old video of the bully fucking his girlfriend in a changing room and was about to fall asleep when he got a text. It was the sort of text he’d received more times than he could count; a photo of their girlfriend’s hand wrapped around the bully’s thick cock whilst giving him a blowjob. Only this time their girlfriend’s hand was adorned with a giant gleaming engagement ring!

Then keeping them locked up in stalls where they can be safely milked by hand every day to drain their poor sensitive oversized tits.

Then selling the milk to other trans girls so they have a tasty and nutritious source of estrogen.
