I paused.
If I made myself too hung, I'd never meet a guy who was bigger than me. I didn't really want that, I realized — as much as I was turned on by my new size, I still wanted to feel like the little spoon sometimes in the dick department. I did decide to change one thing, though:
"Penis size percentile: 70
Penis size percentile (erect): 60"
My percentile soft had been 20, smaller than 80% of men in the world. I liked being a grower just fine, but I wanted to try something new for a change.
I set down the pen, and, leaving the book open, I walked over and sat on the couch, leaning back like I was settling in to jack off, and so that I got a good view of the package straining against my underwear. Then, I held my breath, and waited for it to happen.
Just like last time, it started with a tingling, throbbing feeling, but now it was much more intense. My dick shifted and twitched under the light cotton of my boxer briefs, and I let out an involuntary moan as shivers of pleasure shot up my spine. Fuck, this felt good. I found myself absently wondering whether every man on Earth was moaning along with me. Would they all think it was normal? In that moment, I barely cared. Something about the magic of the book made me take this new power I had for granted. Instead of freaking out, I was fucking horny.
My eyes glazed over with arousal, but I forced myself to keep them fixed on my package. It was noticeably bigger now. I remember when I was 15 and first coming into my size kink stuffing socks down into my bulge and looking at myself in the mirror, imagining it was all me. The package I was sporting now would have taken more than one pair. More than two. And it was still growing.
By now my dick was so hard and so big that it was lifting the strap of my underwear on its own, and I saw its head poking out, leaking precum over my pubes. I grimaced through my arousal at the mess — I wonder if I can get rid of the hair down there? — but before I could really get annoyed a final wave of pleasure ten times as strong as the others shot through me.
My dick rocketed upwards. Where just minutes ago it had nearly reached my navel, it now easily passed it, growing with each pulse until it sat bobbing just below my chest. On impulse, as the wave of growth subsided, I leaned forward on the couch and locked my lips around the head. Even after the bliss and dopamine of the growth, it felt amazing. I felt the head, thicker now, so wide I could barely fit the tip in my mouth without scraping it against my teeth, and, before I even had a chance to probe it with my tongue, I came. My mouth was full of cum within a moment. A moment later, and it was overflowing, semen leaking out between my lips as I refused to take my mouth away from the head of my dick.
As the orgasm subsided and my new monster began to soften, I let it fall from my mouth, eyes wide, panting.
For what felt like the tenth time that day, all I could think to say was: "Holy shit."
