A Condom Big Enough for a Futa Ch. 02

Fetish

Hello! It took me awhile due to some unforeseen illness, but the second chapter of this story is finally done. This contains all the same elements as the previous chapter, but now includes futa on male, anal, and all the way through. As before I will give a warning: this story is unrealistic. The sizes in it are extreme and it is generally ridiculous. Do no...

"You get what you fucking deserve, bitch." The police officer said, raising her voice as she slapped Kasey across the face. Her cheek stung, but she enjoyed the stinging sensation.

Everything was a blur. Vague shapes came and went, colours smeared into one another and voices echoed nonsensically. Only one thing was clear to her dulled consciousness; pleasure.

"Liz," Bianca groaned into the phone after yet another beep, "It's been a week. Pick up already." She hung up and set her head on the table, breathing heavily while her hands gripped her shirt. Her knuckles were white, and her nails dug deep into her palm. It was the only way to stop herself from relieving the brutal ache between her thighs. A week without...

"You're really gonna wear a dress to a movie?" Amanda asked. Amy smoothed out her only dress, "Hey, I don't know if or when I'm gonna grow again. This might be my last chance to use it." Even if she didn't grow, the fabric struggled around her curves, threatening a tear whenever she breathed too deep. Her cock stood out unclasped, so Amy used a few straps t...
