I had been sucking the cock of my office rival Gary. He was arroused from beating my ass everytime my ex wife sucked cock better than I did. Then Mistress Dianne stepped forward and said:" Now for the finale. Step forward Julius." The large Black man accompanied by two female slaves then stepped in front of me. He was HUGE...his cock looked like was as large as an empty paper towel tube. perhaps ten inches long and very thick. As he stood there, the girls were licking and sucking his HUGE tool. This caused it to become erect and jut out its full ten inches. Dianne then said:" Julius is going to fuck slave 13 tonight. Slave 13 has never had a cock this big in his ass before and the entire event is being video taped. "Fuck the white slaveboi Julius"! I struggled in a vain attempt to get free of the fixture i was attached to. No hope.....Julius stepped behind me, his HUGE cock bouncing . I felt his large caloused hands on my waist. A line of male guest had lined up in front of me...waiting for me to suck them off....and this HUGE Black cock was about to split me in two. I was helpless to resist. I felt pressure as he pushed his HUGE member into me....then he encountered my pleasure ring like it was a brick wall. My body recoiled jerking forward ...the cock in my mouth was jammed deep in my throat as my lips rebounded off his stomach......the crowd cheered ...someone yelled "fuck that ass" and the crowd began to chat..."Fuck that ass", Fuck that ass". i was wiggling to try and get away from the big cock buried in my mouth as Julius lifted me by the waist like a toy doll and with one massive stroke buried his HUGE cock deep inside me, popping past my spincter, his HUGE thick cock opening up my pleasure channel for all time. I was gagging from the thick cock in my throat and a I tried to scream as Julius buried his big thick cock deeply inside me.My cock got immediately hard again shooting off and jerking from the sensation......i was cumming from being butt fucked by this HUGE cock......then waves of pleasure moved through me...and i began to fuck back......moving my hips in response to the powerful thrusts that were the source of both intense pain and pleasure. I could not get enough of that BIG BLACK COCK that was hammering me like the piston in a big diesel rig. I had become the total butt boi for a Black Master and a room full of former co workers all of whom has used my mouth or my ass. Julius pulled my hips to him as he buried his cock inside me for the last time, ejecting his cum deep inside me. My erect cock, puny in comparsion to his was jerking and spurting......and the fifth of my six former co-workers was emptying his balls in my mouth, cum overflowing and dripping down my chin as i moaned and beggged for Julius to both stop and not stop....then.....as forcefully as he took me, he withdrew....leaving me aching for his big cock......the last of my former co-workers presented his dripping cock to my mouth and commanded me to suck his dick.....i did so eagerly.....i was now totally converted.....pussy boi....being used and abused had excited me in a way that had never occured before....As the crowd began to depart, i was released from my restraints and commanded to clean up the mess on the floor....cum had pooled there.....i knelt to complete my miserable task....and as I knelt there, Gary mounted me once again, fucking me as i licked up cum from the floor......"Make sure this gets on my version of the video!" he said. i had forgotten that this entire evening had been captured on video and would be sold on the internet. The conversion of Jim to Slave boi 13. Gary finished came in a few minutes, gave me a few swats and commanded me to clean his cock with my mouth. I was just finishing up as Dianne came into the room with Trainer from Chuck's Neu bois.......i was hosed off, chained and loaded into a van to be returned......on the way back, Trainer commented; "you apparently did good this weekend bitch. Master will be pleased, you made a lot of money for him. This week you will be trained and prepared for an auction. Master doesn't keep bois after they are fully trained.....he sells them to the highest bidder.......congratuations on your graduation.
