A moment to collect myself,then "wait what!"

Despite my exuberant erection I wasn’t aroused. I felt that distinct break between the person I’d been a minute ago in the midst of sexual ecstasy and the person I was now who was asexual as I ever got. Which wasn’t that asexual given that I was a generally perpetually horny teenager. But the point was that I was currently saner and I was sort of freaking out about my situation.

Why was my sister acting like a sex-crazed maniac? Did I really just get a double blowjob from my sister and her roommate? Was I experiencing a psychotic break? Was I dreaming this?

I pinched my left wrist hard as I stared Imogene on her bed across from me. She was on all fours and waving her ass back and forth at me, her dress falling down her back to reveal her cute little butt clad in only her striped thong. She looked back over her shoulder at me with a dirty smile, “Axxxelll….aren’t you gonna fuck meeee?”

I blinked and shook my head as if to ward off this surely false scene. I turned my head to look at Jane behind me at her desk. She was lounging in her chair, shoulder blades against the edge of the desk and one leg casually draped over the chair back. Her ever-present smartphone was back in front of her face; apparently the internet was a lot more interesting than her roommate trying to entice her brother into some taboo sex. Though I did note her nipples were clearly poking at the relatively thin material of her Nirvana t-shirt.

“Come on, Axxellll….” My sister’s teasing sex voice drew my attention back to her and I had a front row seat to her thong coming down and her thighs parting on the bed. The glistening lips of her slit lay exposed to my eyes amongst the perfect tight little globes of her ass. I could feel my horny id threaten to take over so I made an awkward b-line for the on-suite bathroom, pulling at my jeans and underwear as I went.

I closed the door and mostly failed at putting my boner away. It was generally too large at the moment.

I spent a few moments trying to excise my brain of sexual thoughts but the erection was stubbornly resilient. All the normal tricks failed and I got the feeling that my ability to maintain an erection was more dependent on Imogene’s will than mine at the moment. That begged the question whether she was actively willing it to stay hard or if the way her power worked meant it would just stay this hard until she decided otherwise.

Wait. What did she do with that semen she’d been playing weird telekinesis games with?

Why was I worrying about that now? Something decidedly strange was going on and had been ever since I’d encountered that silver haired lady obsessing about earrings. Everybody was acting off. Those students at the pool table. Ms. Braddock. She’d gone into that secret passage with me right there and that didn’t make sense now that I thought about it. Why have this hi-tech hidden doorway and then let some random dude see you use it? And then there was Jane. She’d never revealed her true form in my presence the other times I’d been to the school and now she just couldn’t be bothered to tap her wrist watch before I came in? And then Imogene just casually hanging about in the nude in front of me?

It felt like… it felt like everyone was just sort of ignoring me. Not completely though. It was more like they just didn’t care about me or anything I did. I remembered Imogene’s casual disinterest when I told her I was going to show Jane my dick. But wait. How did that explain why my sister was suddenly all about getting drilled by yours truly?

I thought about that silver haired woman again. Mental powers. There were mutants here with them. Telepathy and mind control. That had to be it.

There was this senator on tv always going on and on about how dangerous mutants were. I was maybe starting to believe he might have a point. Except, you know, I couldn’t really muster up any real concern cause my mysterious mind controller was apparently using her powers to get me laid. Wait. Shouldn’t I be indignant that this person was messing with my sister’s head? Making her think it was okay to have sex with her brother?

Yes… yes, I should. My mental voice was less than fully genuine in tone.

I opened the door to the bathroom as I made a decision.

“-you know I could impregnate every girl who’s got an egg ready with these? Like heat seeking missiles.” Mused my sister as she lay upon her bed. She stared at a point a foot in front of her face and the orb of semen grew from thin air.

“Gross.” Said Jane, “And really, through clothes and up the vagina without seeing?”

The sphere of jizz seemed to burst and then abruptly vanish as Imogene replied, “Yep. I’ve got the same awareness and control over a girl’s eggs. Guiding them to each other is a cinch. And an individual sperm cell is microscopic-dead easy slipping through clothes.”

“Huh. Totally makes sense now why you having sex with your brother isn’t an issue. You can cockblock his little guys with your mind.” Said Jane as she absently swiped at her phone’s screen.

"you want to impregnate every girl in school with my sperm, you think that's normal" I said meaning it as a question but it came out as a statement. I quickly closed the bathroom door whatever decision I thought I had made forgotten I was back to freaking out. I spent the next two minutes thinking in circles about a school full of pregnant mutants and getting slightly aroused, but stopped when I noticed my erection had gone down not by a lot but by enough for me to realize my sister wasn't controlling it. my face paled as I burst out of the bathroom not even trying to put my penis away to find my sister gone and her roommate sitting there still on her phone "wear is my sister" I practically yelled. not even looking up from her phone "she went to impregnate the whole school" she said in a mater of fact way that both scared and aroused me I immediately left the room to find her.
