Each of you chose a different dish from the menu, you chose Sauerbraten, Jenny the Stir Fried Snake, Tina gotEgg Omelet and Kylie got Cow Milk Kylie. The four of you found the food much tastier than you expected from camp food and ate it until you couldn't eat any more.
Once satisfied, you returned to the cabin talking about the food. After arriving at the cabin you felt too awake to be able to sleep, so you looked for something to do. You opened a door at the back of the room that led to a small storeroom, where you found some board games that you picked up some to kill time.
During the game you started to feel a little discomfort in your belly, but you believed it was because you had eaten too much before and continued playing as if nothing had happened. As time went by your panties started to bother you, which made you straighten them, but the discomfort always came back and you straightened them better, even so it became more and more difficult to make them comfortable.
You also felt that something was different between your legs and were already thinking about asking permission to go check what was privately when Tina said "But what the hell is this? Why are my panties so uncomfortable? No matter how I fix it, it keeps bothering me."
'You too? I've also been fixing mine for some time but I can't solve the problem." Jenny said
'I am also having the same problem." you said
"Me too. This is weird, what are the chances we all have the same problem?" Kylie said
"This is really weird." you said and started to think, kind of instinctively looking at the other girls' pants, where you noticed they had a bulge in their crotch. "Hey guys, what are these bulges in your pants?" you asked. The other three girls wondered at the question and looked between their legs, just like that seeing the bulges in their pants, before looking at you.
"I don't know what it is, but you have one too." Jenny said and you looked down seeing there was a bulge in your pants too.
"Hey, what is this?" you asked and put your hand over the bulge in your pants. You felt like there was something big in your pants that filled your panties, something that you could feel was part of your body. Whatever was filling your pants reacted to your touch and began to get even bigger and stiffer, now stretching your pants as it continued to grow.
"How funny, it looks like you've got a dick and you're getting a hard-on." Kylie said
"Don't say that, not even jokingly." Tina said, hating the idea as she was a lesbian and liked pussies, just out of fear that Kylie's speech would prove true to be real.
How the girl said, what was growing in your pants won out through the waistband, and coming out so much that it was impossible for you to hide. It was undeniably a cock, but it was a horsecock that grew to become a 16-inch pole of meat between your legs.
"Kylie was right, I did grow a cock, and a horsecock on top of everything else." you said
"You mean the bulges in our pants are horsecocks too?" Jenny asked
"No, that can't be true. I don't want to have a dick, I don't even like dicks." Tina said
"Don't be a crybaby, it shouldn't be that bad." Kylie said taking the bulge of her pants, feeling her own dick which, like yours, started to get hard immediately. She held her new 13 inches member as it achieved full erection, but she didn't have a horsecock has she expected, but a different one that she didn't recognize.
"You have a bull's dick, I had already seen it on my aunt's farm." Jenny said
"Interesting, so each of us have a different dick." Kylie said, stroking her cock slowly
"That doesn't interest me. I don't want to have a horse's cock, or a bull's cock, or a human cock, or any cock." Tina said
"Don't be a whiner. It's better than you think. Let me help you and you will see that what I am saying is true." Kylie said and grabbed the bulge in Tina's pants.
Tina tried in every way to get rid of the other girl, but Kylie was stronger and in the dispute pulled Tina's pants and panties, letting her new Human member harden fully in view of all of them. With that everyone saw that her vagina had practically disappeared completely, leaving only a shallow line where it should have been.
Jenny, who already had her hard cock because she had gotten horny just watching the others and also had a different cock, with none of them knoeing what kind it was, said "Tina, your vagina is disappearing."
Tina, who was already finding it bad to have a dick and expressed how much worse she felt to be losing her vagina. In the meantime you, Jenny, and Kylie stripped the undersides of your clothes, all in time to see the last vestige of your vagina's existence disappear, leaving only smooth skin in its place.
"I knew I shouldn't have come to this camp. There's something really wrong here that made me lose my beloved pussy and I have a huge cock. Now all I have to do is have balls too." Tina said and, as if to confirm what she said, the smooth skin where her vagina was has loosened, starting to form a ballsack while the same thing happened to you and Kylie and Jenny.
"Enough of that. Tina, I'm tired of hearing you complain. You haven't even tried your dick yet and just complain." Kylie said angrily.
"I am forced to agree with her Tina. I admit it's weird what's happening to us, but despairing won't help you at all. I'm actually finding this a little interesting." you said. Soon afterward you felt pressure between your legs only to see your ovaries descend into your new ballsack, after becoming your testicles, exactly the same as with the others.
Just like you said, you found it very strange that you had a male equine genitalia between your legs now, but at the same time you found it very interesting, so you used both hands to jack off.
Jenny and Kylie did what you did but Tina didn't, instead she stood up saying "I can't just accept it like that. I will look for the councilor, she will take action on this problem." and tried to put her pants back on, but now it was more difficult due to her new manhood, especially with her erection that wouldn't go away.
Kylie got up immediately and got behind Tina, where she grabbed the girl's cock and started to stroke it while saying "If you won't take care of your hard cock then I'll do it for you."
"I already said I don't want this. Now let go of me." Tina said trying to get rid of the bimbo, but not only failed but made things easier for her, who with that rubbed her own bull-cock between her buttocks.
You and Jenny just jacked off while watching the duo dispute, and before long you felt something traveling through your horse cock as a sensation began to spread through your body, which was your first male orgasm. The cum fired by your dick landed on the board of the game you guys had interrupted, and you saw more cum joining yours, which belonged to Jenny, who was also cumming. When her orgasm ended, the dispute between Kylie and Tina also stopped, because the bimbo made the other girl come against even with her saying she didn't want to, just for herself to come on Tina's back.
When everyone's orgasm was over, Tina started arguing with Kylie, complaining that she didn't want to and that she was now dirty with cum, while bimbo tried to convince Tina to be honest with her body and admit that she enjoyed the experience.
The discussion attracted attention from outside, and soon the councilor entered the cabin saying. "What's going on here? The fight in this cabin can be heard in much of the camp."
You and Jenny helped explain the situation, not trying to hide their dicks by trying to use it as proof of what happened.
"Are you finding this strange? Didn't you guys see the camp flyer before signing it up here? It is very well written that this is a 'Shemale Monster Girls Camp'." Frankie said
"I saw it, but that's because the girls here are dressed up as monster girls isn't it? The shemale is because you are transsexual, at least I think." you said
"Tolinhas, the monster girls in this camp are real and everyone who becomes shemale monster girls. All are girls who have exclusively male genitalia, and anyone who spends a few days here transforms too. You have already started to transform." Frankie said
