It's going strangely well

"Yes, really hot !" Said Elizabeth between her moaning.

The guy trusted his dick even deeper with harder pushes, making her cry out of pleasure. But on the other side of the glass, they didn't even seem to hear her. The girl almost disappeared into the man's cock that he pushed it into the other girl, stretching her pussy wide. Elizabeth could see the bulge of the man's cock on her belly and she clawed the floor under the obvious pain. But the cry out the girl made seemed both from pleasure and pain.

"You love to watch, uh ?" Asked the man.

"I... I was curious... that's not..." tried to say Elizabeth. But she got cut from the man.

"Bullshit, you were enjoying yourself when I came in..."

"I-I... Yes... it was so hot... those bitches, turned into fuck toys and sluts... I... I love it !"

On the other side of the window, the belly's girl started to grow round, and the sex turned more pleasurable for the girl and easier for the man. Soon, she looked like she was months pregnant. Elizabeth could feel that her partner was about to come, but she didn't want his sperm in her vagina... So she pulled him out and turned to him. He was quite handsome despite his salt and pepper hairs, pretty fit too.

"Don't come yet, I want it in my mouth !" She told him.

She crouched and took his cock in her mouth, his juice mixed with hers tasted wonderful and she sucked it with passion. It didn't took really long before he exploded in her mouth and she swallowed everything to the last drop.

"Thanks..." She said, licking her lips.

"You seem to be quite the gal, so I'll give you something." He told her.

He pulled from a pocket a collar with a leash. And gave it to her.

"Here, with that you'll have your own bitch to use." He explained.

"I-I don't..." Tried to say Elizabeth.

But he put a finger on her lips. "No one will judge you here, so, let yourself loose."

He then left. Elizabeth stayed a moment looking at the leash. Wondering what she should do. Some part of her though it was wrong. But another part of her wanted to get free, to have some girl to watch getting fucked and turned into anything she wanted.

Behind her, beyond the glass, the man had left, and the now pregnant girl was looking at her belly, confused.
