Karen brought out a bottle. "This is the best option for your fur, Chad. Rick, mind giving us some privacy?"
"Fine. I'll be showering over there if you need me."
Karen led Chad into one of the stalls and threw up the curtain. Chad still found it awkward to stand and walk on four legs, but the moment he felt warm water washing over his fur and Karen's soft hands working in the shampoo, his worries melted away. She smiled and knelt down, water pooling up around them, looking into his deep eyes with the large, dog-like pupils.
"You know, Rick wants me to harvest your sperm. For research purposes, he says. He thinks that he can make more hybrids from your DNA, or so he's told me. Well, I have my own ideas about what to do with you, stud."
Chad no longer had the mental capacity to understand a word she was saying. Instead, the few thoughts that passed through his animal brain were directed at Karen reaching underneath him. There, she found what she was looking for: Chad's penis and testicles, both of which now hung loosely and swung in the air like a trapeze suspended from the top of a circus tent.
Wrapping his arms around his midsection, Karen suddenly flipped Chad onto his back, giving her the access needed to start licking the tip of his cock. Within seconds of sucking on it, he was fully erect and his red raw meat emerged from its thick foreskin.
"Now let's do it doggy-style, Chad", she snickered. Putting her hands on the floor, she mannered Chad until he was on her back, and his tip was aimed right at her vaginal entrance. With one swift motion, he entered her.
Karen began to move in and out as Chad found that, to his surprise, he wasn't entirely enjoying himself. Sex was not the same when you had a foreskin. And what was that feeling?"
Suddenly, Karen interrupted. "Yes, yes!! Now that you're getting into the hang of things, it's time to seal the deal!"
Chad could feel his tip starting to inflate, until it was too big to remove from Karen's pussy. At the same time, he could feel semen start to travel up the length of his urinary tract.
Without a noise, he ejaculated right into Karen. By the time his tip deflated and he was able to pull out, the amount of sperm leaking out of her hole was enough to make a small puddle around her.
Karen fell over, and petted him. "Good boy, Chad. Mommy likes it when you impregnate her like a bitch."
Suddenly, the curtain came flying open. Rick stood there, his own erect cock sticking out. "Then how about a second round?"
