Right, to the music wing

The gymnasium didn't seem like a very good choice. It was too open and you would probably get swarmed in there, so you turned right toward the music classrooms. You tried every door, but none of them budged until you got to the band room.

You yanked it open, but right then a very attractive nun with huge tits hanging out of her habit grabbed hold of your suit jacket.

"FUCK ME PLEASE!" she shouted tearfully. You only just ripped the suit open and sacrificed it to the pack of lustful young women. Finally you kicked the door closed and blocked it with your own body, but there were a lot of women on the other side. Their combined weight was enough to slowly **** the door open, and your dress shoes didn't have enough friction to stop them. Suddenly, a clarinet smashed into the door next to your head and you held up your hands to block any more flying instruments.

"Don't come any close- oh wait, it's a man," a young girl said.

"Oh thank God!" another girl said.

"Help me out here!" you shouted, "Find something heavy!" The two of them grabbed a leather couch and heaved it into position. It still wasn't enough, so you piled a cabinet on top of it, and finally the teacher's desk. After that the door remained shut.

"That was close," the girls said. At the same time, in the same voice. Oh dear, you thought, twins. sure enough, they were like blonde reflections in a mirror. The only way to tell them apart was one wore a pony-tail while the other let her hair down.

"What are you doing here though?" the one with the ponytail asked.

"I was in a wedding on the church side of the building," you said.

"Must have been some wedding," the other twin said, "I'm Alexis, and this is my sister, Bethany."

"Hello," you said.

"What's happening out there?" Bethany asked.

"You saw what happened," you said, "Every woman has turned into a sex monster."

"Every woman?" they asked in unison. You confirmed it by showing them the newsfeed from your phone.

"We were in AP Geometry when it happened," Alexis said, "The teacher just started stroking herself in the front of the class, then all of a sudden all the senior girls started **** all the boys. We ran in here to hide."

"And you didn't lock the door?" you asked, "Nevermind. If you had, I wouldn't have made it."

"Why aren't we affected though?" Bethany asked.

"As near as I can tell, it's only adult women," you explained, "18 and up. What?"

Bethany started balling her eyes out and her twin sister held her tight to console her.

"Today is our 18th birthday!" Alexis cried out in terror.

"So why aren't you affected then?" you asked, "Hmmm, maybe you have be exactly 18 years old to the minute."

"I don't want to hurt anyone!" Bethany cried, "I don't want to become a sex monster!"

Is that really the worst thing in the world, you thought. But you made an effort not to ogle the to sexy teenagers, that wouldn't have been cool.

"Hey, hey, it'll be ok," you said, "I won't let you two hurt me."

"You're locked in here with us!" Alexis said.

"You haven't gone insane yet," you said, "And don't take this the wrong way, but I'm not really worried about the two of you being able to overpower me." Forget a head taller, you were almost an entire torso taller than the twins.

"Well, what about you?" Bethany asked, "Why should we trust a strange man who wandered into a high school?"

"I mean, you got me there," you admitted and went over to sit on the other side of the room, "Feel free to keep your distance if I make you uncomfortable." You still grabbed a music stand to defend yourself when the time came, but for now you didn't think you needed it.

Alexis and Bethany sat down across from you and held each other's hand. You watched each other intently until that started to feel uncomfortable than just being in each other's presence. It was Alexis who broke the awkward silence.

"Oh this is ridiculous!" she said, "We're locked in here together, so we have to learn to trust each other!"

"Says the literal time bomb in the room," you muttered under your breath.

"Whose wedding was it?" Alexis asked.

"The girl of my dreams," you said with resignation.

"You and her?" Alexis prodded.

"No."

"Oh, I'm sorry."

"I don't know which part was worse," you said, "Watching her marry some other dude, or when she turned into a ravenous sex fiend." The twins shivered when you said that, which was understandable. The situation was pretty unnerving and that would be them sometime today.

It wasn't fear though. The way Alexis clenched her thighs together and Bethany subtly bit her lip... wait were they turned on by the idea? Were they starting to lose control now too? No, they weren't acting like all the ladies had during the wedding,

"Nice suit," Bethany said.

"Yeah, thanks," you said without much enthusiasm.

"I mean, even for a wedding you're well-dressed," she said and laid her cheek in the palm of her hand. Was she checking you out without turning into a feral nympho?

"I was the best man," you said.

"Wait," Alexis said, "So the woman you love asked you to be the best man at her wedding to someone else?"

"Yup!" you said bitterly.

"Wow," she said bluntly, "I am so sorry. That sucks." Bethany opened her mouth to speak, but shut it immediately.

"Something to share with the class, Bethany?" you asked.

Her cheeks flushed bright red and she asked, "But then after, you know, did you and she..."

"Did I take advantage of the woman I love at her wedding to another man?" you asked, suddenly mad, "NO! No, I did not!"

"But... you wanted to," Bethany said, "Didn't you?"

Did you ever. As soon as you saw Diane humping every dick she could get her hands on, in her wedding dress no less, you had considered doing just that. With nothing better to do, you started fantasizing about fucking Diane in her wedding dress at the altar while she screamed her wedding vows to you.

"Was that before or after the 'I do's?'" Alexis asked.

"During," you said, "Actually she never actually said it, hold up. She never said 'I do!'" That epiphany made you jump to your feet in excitement.

"She's not married yet! Not technically!" you said.

"Yeah but she's one of those sex monsters now," Bethany pointed out, "I don't see what there is to get-"

Before she finished, she jolted. Her eyes flashed pink as she stared blankly at you from across the room and there was no doubt, she was exactly 18 years old now.

"Oh no," both twins whispered in terror. You ran to her side and laid a gentle hand on her shoulder.

"Hey, Bethany," you said, "Look at me. It'll be ok, I won't let you get hurt."

"I don't wanna hurt you!" she shouted.

"Beth, we'll get through this togeth-" then it was Alexis's turn. Her whole body twitched suddenly and just like Bethany her eyes flashed with pink light.

"I feel so hot," they said in unison and started petting their breasts through their school uniforms. Now you really were alone with two psycho nymphomaniacs.
