Why not?

While Ashley explains the mana system in more detail to her still-unnamed friends, with increasingly raunchy noises, you try out Jill's ideas.

"First, just feed some of that energy into my hand. Not too much! It's just an experiment. Ohhh, it's tingly and warm. But it's gone instantly. What does it feel like for you?"

"It's a weird fullness or pressure in my groin, mostly my testicles but not at all painful."

"Ok, try again here" She moves your hand to just below her belly button. "Woah! That was different. Definitely fullness and energy, but only lasted an instant."

You remember how the power was leaking out of you rapidly until you tried to close it off.

"I'm going to do it again and keep it up for a few seconds, this time focus on how you can keep it constrained. Imagine it's fluid and running in every direction."

"OK, ready. Oh, my. Yes! It worked. Give me a bit more now?"

You still have a fair amount, so try to give her a small diamond's worth.

"My, god, Ed. This feels amazing. Give me a kiss?"

You don't hesitate. She's shy, but excited and cute. You also get a surprising amount of energy from it. Apparently first times are valuable.

"Nothing! I mean. That felt great, Ed. Magical, really. But no gain of energy. Was it worth anything to you?"

"Probably almost half an orgasm."

"Wow! You're going to love the rest of my firsts, then."

You notice that Julie has taken you out of her pussy, because one of Ashley's friends immediately sucked it, hard. Everyone looks at you because you yelped.

"You taste good, Jules."

Jill looks at you then reaches a hand down your pants.

"You've seriously taken your cock off? And they're passing it around?"

"I think - unh - that they are competing to make me react right now."

"Hey Theresa, hand it here for a second I have an idea."
