Keep It.

You consider you decision for a long while. Ms. Reacher and Nala wait patiently but keep their eyes on you. You look at Ms. Reacher. Could you really put this onto her? Onto anyone else? And Nala said you were doing well! You damn near caused a traffic accident and, more than once, seriously considered ripping someone clothes off with your teeth today. And that was someone with good control, apparently!

You shake your head and say, "I can't. I can't let you do this to yourself, Ms. Reacher."

"And I can't let an eighteen years old girl hold this much responsibility!" she counters.

"You don't understand. I can barely keep this under control. But I can manage it. Who knows how it'll interact with you? What it'll turn you into?" You turn to Nala and say, "I'm keeping it. That's my final decision."

"Are you certain?" she hems. "After too long I will no longer be able to remove it. This will be your life until your dying day. Consider how you once saw your life going. Marriage. Children. All this will likely become impossible."

You don't normally consider that far into the future. But you have tonight and are fully aware of the consequences. You give a firm nod of your head and can almost feel that life, a normal life, die with that simple motion.

Nala smiles and says, "You continue to impress me. I have an offer. It will take some convincing of certain powers that be but I believe I could register you as my apprentice. I could show you how to use this power for good. If you are willing."

Your eyes go wide, "You want to teach me magic? And have me fight monsters, like you?"

She nods, "In time. If, that is what you wish."

You smile and give another firm nod, this one feeling much lighter than the last.

Ms. Reacher reaches out a hand and places it on your shoulder, saying, "I'm proud of you, Rebecca. This is a big burden you're placing on yourself. If there's ever anyway I can help you, just ask."

"Actually," Nala chimes in. "I believe, based on what I've seen, that you could prove to be an invaluable ally to her..."

A few years later you find yourself, once again, at Carol Reacher's house. You're a frequent guest these days, though few people know it. Currently you're ramming your cock into the third high school girl of the night. She's a lot shorter than the other two but her tits are massive, especially for her tiny frame. You had her sit on the sidelines and watch while you fucked her friends senseless, the two of them kissing and rubbing against each other while you switch between their pussies. She nearly exploded in her seat, especially since you ordered her not to touch herself. But now she was smiling and moaning as she finally got what she deserved. You lift up her legs to pile-drive into her, her eyes crossing even as she grins and moans and cums all over your cock. Feeling cheeky, you pull out and shower her in cum, covering her from head to toe. Even after cumming four times with the others, and once before with this one, you can still produce a crazy amount of cum if you want to. Nala says it's a sign of your power growing. The Council doesn't like to hear about you getting more powerful but you also don't like to kiss and tell so it all works out. Your fuck buddy is in a pleasant sex coma like her friends now and you gently place her in bed with the others.

"Is that gonna be okay?" Carol asks from the doorway. Apparently she's all finished with her two students from down the hall.

"Relax."

You wave a hand over the sleeping girl and the semen vanishes into little glimmers of light. Just to be safe you check the perception filters you placed on their minds. It's delicate work and Carol recognizes the look of concentration on your face and doesn't disturb you. The filters are mental magic you place on all of Carol's students in her "club" so they don't realize they're sleeping with a woman with a penis. It's better not to spread that information around so fewer people could possibly learn about magic. The Council doesn't like security breaches.

"There. All good."

Carol rolls her shoulder, "I still can't believe you're so chipper after all that. I feel so old standing next to you."

You put your fists on your hips and say, "You only just turned thirty! If you want me to prove just how young you are..."

With a thought you flip her switch and she gasps at the feeling. You technically aren't supposed to do this against someone's will but you know Carol enough to know she won't complain. She bites her lip, considering. Your phone rings in your jeans on the floor and makes the decision for you.

"Sorry," you tell her as you scramble for the phone. "Duty calls! Nala? Yea, I'm on my way now. Just had to stop for a bite to eat. No, no one was injured! Much... I'm kidding, Master. Right. Be right there."

With another thought you dampen Carol's arousal to a little lower than her usual horny self. She just said she was tired after all and you doubt any of her girls are gonna be good for another round until morning. You get dressed, gather your gear, and head off into the night. There's a monster to hunt down and you are teeming with energy. You love your job.
