As Jules slept his cum began to alter that which it had hit. For you see the flashlight Jules had gotten was somewhat defective. Even the shop owner had no idea. Whenever its beam hits the reproductive organs of an individual it causes an excess of magical energy to be held in them. This causes their cum to be more magical than normal. That on its own would be concerning but because Jules has a mythical cock already infused with mystic energy it is more powerful than the others. The first was Jules's underwear, the synthetic fabric became more natural as the leg holes became undone. The tears ran up to the waistband as the cloth became leather which soon got covered in brown fur. In a matter of moments, Jules now wore a loincloth that barely hid his balls.
Next to change was the mattress. Below Samantha her covers became silk and her mattress became incredibly comfy. However, the excess of residual magic needed something to be absorbed into. It soon drifted into Samantha's sleeping form. It's unclear what made the magic change her to be the following. First, her ears began to grow pointed. Beneath her eyelids, her irises became yellow with a slight glow. She felt a pain race throughout her body but was unable to awaken. Her teeth sharpened within her mouth as she tossed and turned. Her nails then grew into sharp claws tearing through her blanket.
Except for most of her lower half her body began to grow a light dusting of hair. This began to thicken rapidly as the changes continued. Her nose pushed out a little as her ankles rose. The hair she currently had softened into fur as it grew even thicker. Her muscles began to thicken as her breasts began to shrink. When they were about halfway her cock began to take on a canine appearance as a sheath surrounded it. By now her feet had become paws. Her already large cock then tented her panties as it grew larger. Pads appeared on her paws Sam's torsos thickened out. Her breast was almost gone as she moaned in her sleep. Her mind was filled with female werewolves to breed as he humped the air. His cock slipped out of its confines as his face pushed into a muzzle. His breasts were barely noticeable as his pecs grew in. That was not the only thing as a tail grew straining his panties even more. His face pushed into a canine muzzle as his hair began shrinking into his scalp. As the changes began to finish Sam grabbed his cock and began to cum. he let out a loud howl as he did. The last bit of magic eats away at his tearing panties leaving him naked. The noise stirred everyone but him awake. Jules barely had time to get out from under his mattress before the support beams broke sending Sam through both his and Jules's bed. This woke him and he looked around startled.
"what the..." Miranda whispered as she looked at the 7'4" werewolf in the remains of a bunk bed. Sam looked at himself in shock, which shifted to horror as he realized he was naked. He quickly tried in vain to cover his new canine genitals. Given how they were almost as large as Jules it did not even remotely work. Thankfully Miranda snapped out of her shock and ran to the bathroom. She came back with a towel to give him some modesty. Everyone was confused about what was happening, especially Jules. As best he could remember he never used myth on Samantha. Theresa then pointed out how the destroyed mattress looked nicer than Sam's original one. Her sister Maria then pointed out how Jules's boxer shorts had changed too. Jules was shocked and explained she had no idea how he could've caused this.
Sam however smelled Jules's scent mixed with salt and followed it to the bottom of his mattress it wasn't long before it was revealed Jules had caused this with his cum. The 19-year-old was horrified at what happened. She never had this problem before she changed it. Just as Alex was saying they should punish her Sam stopped them. "we shouldn't blame her for something that she had no control over. Besides we were all put in this room together because of our unique looks" Jules was stunned at the fact that Samantha had spoken on her behalf like that. While Sam was telling them what it felt like to be a werewolf man he pulled out his flashlight. Shining the highest blue setting on IN he hoped it would fix the bunk. He didn't want to be in more trouble than he already was. It took a bit but eventually, the damage was undone. The entire thing looked like it was made for heavy-duty things.
When she returned to the group he learned that they had all wakened up by the howl and the bunk was undamaged. "it's a good thing we got the heavy-duty one right" said Sam, he could smell the aroused scents from Susan. He found himself wanting to mate with her. This sudden thought shocked him and he quickly made an excuse to leave the room claiming he needed to do werewolf things. Everyone else just stood there until Susan began to yawn. One by one they all fell back asleep and it was only when the day broke that Samantha came barreling inside her brown fur disappearing as she returned to her previous human form. She let out a yawn herself as everyone was getting ready for the morning. The classes were optional so Samantha decided to rest after her change. Jules hung back after everyone had left to apologize to Samantha one last time. Looking at the flashlight in his purse he wondered if he could return Samantha to human. Jules then decides to...
