I was sitting out at a park, taking in the fine greenery around me on my walk when a Particularly Attractive Woman strode by me, winking and smiling to me as she did. I watched her pass, my gaze obviously stuck to her as she hips swayed and her hair was swayed by a gentle breeze. She gives me one last glance back before disappearing around a corner. I smile and log it into my memory for later, then continue on my walk.
I only get a few paces before I start to feel something. Not sure what, but something feels off. I doesn't feel like arousal itself, though I can feel that welling up from my loins as well. I glance around for a bench and don't see any, so I quicken my step. That woman was really sticking in my mind and I was going to need to sit for a bit to calm back down, I could already feel my penis becoming erect in my shorts. At least I thought I did, I felt the familiar feeling of the fabric of my boxers against the head as it slowly slid down ward, and of the arousing swell of it increasing in girth as it grew. As I walked on, becoming more aware of my own size by the second, I realized I wasn't erect, or getting erect.
I stopped and looked down to see a more prominent bulge in my shorts, but no sign at all of any hardness. I reach a hand down and touch it, then cup it. It's me, and I could now feel it press against my hand as my dick continued to grow. I resumed walking and now could feel that my balls, too, were growing. I could feel them rub against my thighs and how my cock was now resting against them as it swung freely in my shorts. With every step I could feel my shorts becoming tighter, my cockhead reaching lower, and my balls growing rounder. I felt anxiety well up alongside my increasing arousal. Where was I going? Could I get to my car? What then? My mind raced with thoughts of what to do as I became increasingly aware of how award it is to walk with such large, and still growing, genitals.
