The next day you meet up with your girlfriend after school. Many of the girls were walking strangely now as they got used to their new meat sticks, and your girlfriend was no exception, clutching the front of her black skirt and trying to take as small steps as possible. You call her name and she turns to you smiling and waving you over.
"So how did it go?" You ask.
"Yeah, it went well, it just wasn't exactly what we expected." your girlfriend said
"What do you mean by that?" you asked
"I'd rather show than tell. Let's go to my house and I'll show you there." your girlfriend said
You went to your girlfriend's house, and there you went straight up to her room.
"Now I want you to see this." your girlfriend said and turned her back to you, took off her skirt and panties and slowly turned around facing you again. Her ballsack was huge, with testicles the size of oranges, but you didn't see any dick, just a hole that was just above her balls.
"Where's your dick?" you asked
"It's inside me. In the procedure they gave me a horse dick. He has been manipulated to have the colors of a human cock, but is otherwise purely equine. He stays inside me except when I go to pee or have an erection." your girlfriend said
"And you didn't question? They must have made a mistake." you said
"I questioned yes, but they said it was exactly what the school had asked for. All girls should walk out of there with a horse dick between their legs." your girlfriend said
"Can I touch it?" you asked
"Are you not disgusted? I know you said you didn't care if I had a dick, but we were hoping I had a human dick." your girlfriend said
"I already said I won't dump you because you have a dick, I don't care if it's human or equine." you said and grabbed your girlfriend's balls.
She moaned and jumped back in surprise, and the tip of her cock was visible protruding an inch or two from the hole above her balls.
"You don't want me to touch it?" you asked
"That's not it. It was just too sudden and I can't help but feel insecure about your reaction when you see the full size of my cock." your girlfriend said
"Don't worry about these details, just relax and leave it all to me." you said and put an arm around your girlfriend, and with your other hand you grabbed the exposed part of her dick.
She reciprocated and hugged you tight while you caressed her cock, which was coming out as it got harder, demonstrating all its majestic size. When you felt that her member had reached the maximum erection, it already displayed all of its 25 inches that pulsated in your hand.
"Ohh, it's huge." you said
"It is. They said it was so we wouldn't miss out so we couldn't fuck anyone so we couldn't get anyone pregnant." your girlfriend said.
Her cock was too big for your hands alone to be enough, so you took off your clothes and stood in front of her, pressing her cock between your legs. You then moved your hips to simulate that she was fucking you, while stimulating the rest of her cock with your hands. you also rubbed your own cock against hers. With a spasm, your girlfriend held you tight and pushed her hips behind you, and she came squirting her cum forward.
