I arrived at my apartment in a state of fear and arousal. That strange wobbliness in my limbs was still there making me feel unsteady on my feet. Even on the drive home, I kept feeling dizzy.
As I got out of my car, outside of my apartment block, I attracted the attention of a neighbor's dog, a golden retriever named Sissy. She kept jumping up on me as I unsteadily made my way to the lifts. Licking and barking and sniffing at the strange bulge in my pants. I tried to keep my dignity intact as I ran into the lift, pushing the animal away.
The owner, a young blonde gym girl who was way out of my league, ran to collect it. As she grabbed Sissy by the collar, she looked up at me. Well, she tried to, at least. Her eyes stopped on my bulge.
"I'm sorry I...," she trailed off.
Mercifully, the lift doors closed, and she was gone. My cheeks burned. I hope I never, ever see her again. How would I even explain any of this? I was vaguely aware of the dog hair and saliva on my clothes, but honestly, none of that mattered right now.
I stumbled through the door of my tiny apartment, feeling the growing stiffness in my pants. My mind was flooded with lewd imagery. I was aching with need -- all I needed was a wet pussy to sink my new, big cock into.
I didn't bother closing my door, I just dropped my bag and started undoing my pants. The change was very real: skin from my pubic area to halfway up the shaft was pitch black, from then on it gradually shifted to a bright red. The same red that stone had been. The head of my cock was broad and amber colored -- hard and see-through. It was growing stiffer and stiffer, standing at a proud 18 inches. The bulging veins along the shaft throbbed with my heartbeat.
I threw myself on the couch -- there was no way I would make it to my bedroom -- and started stroking along the shaft. Waves of pleasure flooded my body -- it has never felt this good before. I rubbed the foreskin with both hands -- up and down, up and down. I thought of the young blonde girl with the dog. Her lithe, athletic body, her eyes on mine... What did her pussy look like, and would I even fit all of me in there? As the pleasure intensified, something strange started happening. Little by little, the new amber head of my massive cock started glowing. It brightened with each stroke until it was almost blinding.
