I want to but something stops me

"Is... is there anything else you'd like for your birthday present, Phil?" My older sister, Jenny's, words echoed in my head as I looked down at her, kneeling on the floor in front of the couch, a small dribble of my semen leaking out of the corner of her mouth. There definitely was something I wanted, something I'd been dreaming of for a long time... but the problem I faced was whether I should ask for it or not. I'd been fantasizing about my sister Jenny since I first hit puberty, and now, tonight, I finally had the power to make those fantasies reality... but seeing her ****, hearing the hesitation in her voice despite my control, raised the question. Should I push her further?

Glancing down at my still hard cock, the preternatural erection refusing to subside, feeling the strong lust coursing through my body, I knew what I had to do, knew that I was going to take what I wanted. And what I wanted right then was her! "Yes, Jenny, there is." I assured my sister, my eagerness clear in my voice. "I want you..." I started to say as a wave of dizziness washed over me, a feeling of vertigo so strong that I almost fell to my knees. "I want... "I stammered, trying to clear my head as my eyes suddenly became incredibly heavy.

As I felt another wave of dizziness wash over me, I saw the assembled women stir, Stephanie and Stacy looking around the room as if unsure how they got there. "Aunt Marcy..." I stammered, my lips feeling heavy, my speech slurring as if drunk, "what... what is happening?"

"You need rest," my Irish aunt assured me simply, her voice sounding even more natural than before. "You've overextended yourself and now your mind needs to recuperate."

"Why?" I asked as I fought to stay conscious, the room seeming to spin slowly around me.

"Your power allows you to bring your dreams to life, but you still need to sleep, to dream. Without rest, your mind will shut down. You've done a lot tonight, especially for the first manifestation of your power, and now your mind and body are in dire need of rest," Aunt Marcy informed me, a slight knowing look in her eyes.

"I see," I slurred, the edges of my vision blurring, a dark grey cloud encroaching into the corners of my sight. "I think... everyone should go back to bed," I managed to command just as I lost consciousness, falling back onto the couch in a deep slumber.
