Tiffany and Jennifer were best friends and went to the same college. Now it was springbreak and they decided to take a little trip to "Pleasure Island". They believed the ads, promising that "Pleasure Island" would be the greatest place on earth for girls seeking fun and adventure.
It really sounded like fun and the two girls wanted those weeks to become the best weeks of their life.
So now they had reached the island already and were walking around looking for some fun. "Look, Tif! "Fun Ride" That really sounds like, well fun. Why don't we try it out?", Jen asked her friend. "I don't know. I would prefer to hang out on the beach all day than going on some strange rides.", Tiffany replied a bit nervous. "Ah..Come on. You sound like my grandma. We're here for the thrill.", Jen said pulling Tif towards the entrance of the "Fun Ride". They reached the entrance and a smiling young man led them into the large building and into a small empty room. Before he left he handled the two of them glasses filled with something to drink. "Please drink that! It will increase your experience!" He said, leaving the two girls alone.
Not thinking about anything they both swallowed down the drinks. "Okay, Jen. When does your "fun" begin? I can't see anything special here. Just this empty room.", Tiffany said a bit angry. "I don't know. I thought there would be a ride here. But here's abosolutley nothing.", Jen said confused looking around. "Come on. Let's get out of here.", Tif replied but suddenly Jennifer sank down to her knees. "Oh...I'm not feeling well. I think im sick!" She started to cry. "That pain! It's too much!" Suddenly her butt started to swell, ripping apart her tight pants. A small but growing tail appeared above her buttocks. Tiffany stared at her friend in shock. "My God! Jen! You...you're growing a tail! A horse tail!" Jen looked back at her own butt and realised that Tif was right. She was growing a tail! What was in that drink? What was going on here? Just seconds after Tiffany recognized Jens changes she also felt a pain and sunk to her knees. Just like Jennifer her ass started to expand and rip her skirt, revealing a growing tail.
