I'm stealing the following from AnsemRai: "In the interest of writing a fictional story, I have not included any reference to safe sex or birth control. I imagine it takes place in a world where these things are not necessary."
Content/Spoiler Alert: Primarily Mind Control (sort of), but also heavy elements of Lesbian, Incest, Group Sex, Masturbation, and Voyeurism, in unnecessarily gratuitous amounts, but not necessarily all in the same chapter.

I cleaned up the bathroom well enough, but the entire time, my heart was pounding. I'd just had by biggest jerk of my life, because at the tail end of it I saw my little sister in a hot outfit. It was burned into the back of my eyeballs, and I was struggling not to get hard again.
I call Brittany my little sister because of her height, not her age. She's eighteen, only a year younger than I am, but only five-five, where I'm a little over six feet tall. And I certainly don't call her my little sister for any other reason. The jogging bra she was wearing only managed to push her tits together to create some great cleavage. Her nipples showed through the thick fabric. Brittany has wide, grippable hips and a fine, round ass. Dark brown hair like mine, sexy green eyes, soft lips...
Yeah, I'd stopped trying not to perv on my sister. She's really hot, all right?
And now she wants to talk.
That
thought killed the mood. My nerves were pretty much shot at that point. Oh, well. Time to bite the bullet.
I donned my boxers, shirt, and pants again, and found Brit in her room, sitting on her bed.
"Uh, hi," I said in the doorway.
"Hi," she said, "Sit down."
I did. I was completely at her mercy, and she knew it.
"Look, I'm sorry I didn't lock the door-"
'Bro, that's okay," she said. "I've seen you naked before. Remember the dropped towel last year? And besides, I should be thankful you weren't doing that somewhere carpeted."
She smiled. I felt I could relax a little. I'd forgotten about the towel thing. At the time she'd acted like she'd seen nothing. Apparently not the case.
"Still..." I said. I was genuinely contrite, and totally not struggling to keep looking at her face instead of her tits. She hadn't changed out of her jogging outfit.
"Look, bro, that's not why I wanted to talk."
"It's not?"
"No. I saw... how big you are... now."
"...Oh?" I'm sure my face flushed.
"And you weren't that big before. Nobody grows a cock like that in just a year. Some, sure, but not like that. And how much you came? What did you take, Blake?"
"Take? I..." And then it hit me, what it must have looked like to Brittany.
"No, I didn't take any..." My voice trailed off as more thoughts struck me. She remembered that clearly how big I was from just a towel drop? And how easily those dirty words rolled off her tongue... I shook off the thoughts. My new-found lust for my sister was playing tricks on my mind.
"Come clean, Blake," said Brittany, dead serious. "Or I'm telling Mom and Dad."
"Whoah, hey!" I said. "It's not like that, just... give me a sec, okay?"
My mind raced, but then I decided, "Why the hell not?"
"Brittany, something happened to me today. Do you remember someone coming to the door earlier?"
"Yeah..."
"Did you hear any of the conversation?"
"No, I was... occupied."
I remembered why, and tried not to smile.
"Well, her name was Angela..." I filled her in. About the Organizers, about how they use mortals, about my ability to sense women's libido's and alter them. About how I get a "commission" from the result, an influx of energy I can use in my own sexual life.
"And you decided that a bigger cock and lots of cum was the way to go," Brittany concluded. "Typical
guy
."
"Hey, it was an experiment. I was trying out all the different things I could do. I can also last ridiculously longer and get a damn near solid cock."
I wanted to shock her, or something. Hearing her talk dirty was getting to me.
"You're so full of shit, Blake. I mean, that was an entertaining story, but come on..."
"Kalista McGregor feels differently."
"What?"
"I went to the mall, and..." I told her all about my romp with my high school wet dream.
"Damn. Another good story. But you still could have done that by taking something."
"Have a good orgasm today?" I asked.
"Why do you ask?" She was suddenly nervous.
"First thing Angela had me do was reach out and find a horny woman, and just tweak her libido up. It's how I got proof from her that I could do what she said. I didn't know who it was at first, but then I heard you crying out from your room, in time with what I sensed, and..."
"Stop, Blake," Brittany said. "Just stop. You... you actually believe all this, don't you?"
"It happened. You saw the results. You
felt
them."
"That could have been..."
I didn't have a choice anymore. I had to convince her, or things would go very badly between us. I reached out and sensed her. What I felt was-
"Holy crap!" I exclaimed.
"What?"
"You are really, really horny right now."
