Jar the nymphs

Later that day, you're back in your room. Daisy is looking over your new collection: Four jars, each one containing a naked elemental nymph that has been shrunk down to about six inches in height. The earth, air, and water nymphs are all hammering their tiny fists against the glass, shouting angrily at you, while the fire nymph presses her copious breasts up against her own jar and tries to get the air nymph's attention.

"They're beautiful!" says Daisy. "How did you get them?"

"Morrigan summoned them, and I re-bound them to myself," you say.

"Was that hard? I hear that once a supernatural creature is bound to a summoner, it can be hard to steal that binding away."

"I had their panties, so I win."

"Of course."

"I mean, I could probably only get one wish out of each of them, but it's totally worth it. I wouldn't want to keep them jarred up forever anyway."

"They grant wishes?"

"Sure! Not genie-caliber, of course, but I'm sure we can have a lot of fun with them."

"I think the fiery one winked at me."

"Yeah, I like her. She's cool."

"Here's a thought: If you could bind extradimensional creatures like these by yourself, you could probably leverage their power into binding even more powerful creatures, and so on! With enough work, you could get the goddesses themselves naked!"

"Maybe. Or, we could just get all the girls in the school naked at the same time, or something like that."

"We'll think on it."
