First I decided make nice whole numbers that were easier to work with.
"Average man's penis size statistics:
Flaccid length averages at 6 to 8 inches, with a girth of around 6
Erect sizes range, on average, from 7 to 10 inches, with an average circumference of 7"
I felt my dick shoot up in size once again and felt my underwear tightening around my cock. I took them off completely and allowed my 9 inch cock to spring out in all its glory. Just as I was admiring myself and contemplating what to do with my new found power I heard the sounds off footsteps and jangling keys outside my apartment. Dammit not again. Larry, my landlord had been coming around frequently to "perform routine maintenance" with loud power tools or show the apartment to potential tenants. It started a week ago when a friend sent me a dildo as a gift (A 6-incher for the record) and it was accidentally delivered to him instead. I couldn't believe what he said to me when he found out I was gay.
"Yea I figured you for a fairy the second you moved in. It's been years since we've had a cocksucker in the building. I know you queers are always hungry for the hog and I'm feeling generous. Why don't you get down on your knees and suck me off. It probably bigger than that toy you bought. I ain't no fag but a holes a hole."
Anyway I don't remember my exact response but it was something along the lines of calling him a disgusting pig and claiming I wouldn't want to touch his dick even if it was 10 inches long.
Anyway, while I can't prove anything I think he then started targeting me specifically. After I declined to suck his cock, he started making frequent, annoying visits to my apartment under the guise or repairs or showing tenants around the apartment. Often he didn't give me any warning and it was starting to get on my nerves.
An idea suddenly popped into my head. Maybe if he comes in and I'm stark naked, swinging around a massive 11 inch dick he'll think twice next time before he shows up unannounced. And added to that if I shrink his dick down, maybe it'll make him more insecure and less cocky, figuratively and literally. It'll kill his ego knowing a "fairy" had cock that far out measures his. It sounded like he was outside fumbling for his keys, I didn't have a lot of time.
