I became aquainted with the owner of a small sex toy shop in the city when I went to buy a metal chastity cage.  In order to get the proper fit she took me to the back room and had me get naked.  Unfortunately I got erect.  She had me masturbate and once I came my cock shrank.  She sized me up, found the proper cage and locked me in it. She wouldn't give me the key and sent me home for a trial period.  I returned the next day.

     She had me go to the backroom, get naked and wait.  After an hour she came in, had me bend over and spread my legs, exposing my hole and the cage.  She commented on how my hole gaped and I informed her it had been used quite a bit.  "So, you're a faggot," she commented.  I replied I was.   She wanted to know ho much of a faggot I was.  She handed me some lube and a huge butt plug and told me to work it in.  She left the room as I went to work.  When she came back I had just got it all in.  She smiled and said,  "That is pretty impressive."  She had me stand and I could only walk with difficulty.

     Just as I got up someone came into the store.  She went out front and talked for awhile, then the person left.  She came to the back leading a rather large Doberman.  "Do you suck cock," she asked?  I replied I did.  "This my dog.  It is trained to have sex with humans.  Suck it's cock," she ordered.  I got down on my knees, found its sheath and soon its cock emerged.  I started licking and it soon grew in size.  After a few minutes I could barely fit it in my mouth.  At this point she got behind me and yanked the plug from my ass and applied more lube.  The dog came around back and mounted me.  Once its cock found my hole it plunged forward, skewering me on it.  After a few minutes I could feel its knot moving in and out of my hole.  Eventually it grew too big and we were knotted!  I started to whine as it continued to grow.  Mistress got a ball gag and gagged me so I couldn't make too much noise.  It had a huge knot, softball sized!

    The Doberman turned and we were soon locked, ass to ass.  I was getting used to its size and the pain was subsiding.   "So, this is the faggot you texted me about," a male voice said.  "It certainly is the lowest of the low if it will fuck a dog.  Did it suck it also," he asked.  "Yes, it did and I got it all on video," the owner replied.  Meanwhile the guy had gotten naked, removed my gag and shoved his already erect BBC down my throat.  He fucked my throat viciously with no thought for me.  I was just a faggot hole to use.  When he came deep in my throat I had cum coming out of my nostrils.  He held his cock in my throat as it softened.  Once soft he withdrew it, pissed on me and said, "he'll do," and left.

    I was still knotted with dog when the owner came over and informed me of what just occurred.  He had hired her to perform with her slave at the Tabboo Sex Show that was coming up soon.  Unfortunately her slave had just died and she needed a replacement.  I was going to be that replacement.
