Chap 4 - by A week later I was back at work doing the usual shit churning out computer reports. Only I knew that under my white shirt and tie were cock studs, nipple rings and tattoos. I was always aware of them, however, and they kept me in a semihard state all day. Since I was now required to always wear my cock and ball harness with no underwear, I had to be careful that the bulge in my pants was not too noticeable. So a mild panic came over me when I was told that a new company policy required drug testing and a physical for all employees. We were told not to worry. It would only take a few minutes and was necessary for the company's insurance. Late that afternoon I went down to the nurse's room and waited my turn. When a late 20's babe in a white coat came into the office, I assumed she was some kind of assistant. When she introduced herself as Dr. Susan Fisher, I must have turned red since she asked me if I were afraid of women doctors. "No, of course not" I replied. "Well good, let's get this done." "You're my last appointment of the day and then I get to go home." "Take off your clothes and put on the gown in the other room." "I'll be there in a few minutes." "Here's a bottle." I did the bottle thing then sat on the examining table. She entered wearing her gold framed glasses and her long brown hair pulled back. Even under the white coat, I could see that she had quite a good body. After taking my pulse, she told me to take off the gown and lay on the table. I hesitated and she giggled "Come now, most men love to get naked in front of women." "I could bring a male doctor in if it would feel better for you." "No, I'd rather have you do this I guess" I replied. As I took off the robe her back was to me but when she turned around, I could see her eyes grow large as she saw my gold nipple rings. Her gaze slowly went down to my stomach and there was the black whip with the red tip. My cock was in a semi-hard condition in the leather harness. "My, my, someone has had their way with you haven't they!" "I need to check you for a hernia if you don't mind." I noticed she didn't put the rubber gloves on when she slowly placed her hands on my balls and gave a small squeeze. "Now cough" she ordered and I did. She left her hands around the balls for a few seconds and with her other hand traced the whip on my skin. "Nice work." "I hope you had your nipples done by a professional." I told her I did. Her breathing was getting harder and she took her fingers and felt the rings on my chest. "You know there is a danger of infection." "Now turn over and let's check you for prostate cancer." "Men over 30 should be checked." When I turned on my stomach, my cock pushed into the leather and I squirmed to find a comfortable position. The feel of jelly on my ass was followed with the feel of a probe going into me. "What does this say?" the doctor said. "Sex slave?" "What does that mean?" I explained that I had no choice but to do whatever my mistress told me to do. She asked if this applied to all women in an amused tone. I told her that my mistress did lend me out to her friends if she felt like it. "How about me?" she asked. I turned around to see if she were serious and got a shock when I saw that her lab coat was now open and her glasses were on the counter. Her right hand was on her breasts and her left hand was under her skirt. "How about it?" "Would you do it for me?" She looked so horny that I could not say no. I watched as she took off her lab coat and let it drop to the floor. She looked at my crotch as she unbuttoned her blouse and removed it. Her white lace bra unhooked in front. When she pulled it back, her beautiful breasts hardly moved at all. They were large and white with dark red nipples. The points were already hard and there was a flush on her chest. She unzipped her skirt and let it slide down her legs. The white lace g-string was pushed down and I saw a small black strip of pubic hair above the pale little lips between her legs. She slowly walked over to the table and started to stroke my cock that now was at full length and straining in the harness. Her warm lips found mine and her hot breasts crushed against my chest. My hands went to her firm round ass and I squeezed her cheeks in my hand. Soon I moved up to her breasts and started to suck on her long nipples. They grew even harder as I ran my tongue over them and sucked on the growing hard nubs. I changed places with her and she sat on the table. Pushing her legs open, my tongue now was sucking on her hard little clit and the pussy juice was running into my mouth. The pressure of her thighs was growing around my head as I continued to stick my tongue into her hot cunt. Her moans were getting louder and I was having trouble breathing. One of her hands was digging into my back while the fingers of her other hand were running over the harness on my balls. She couldn't stop touching the stud in my cock or pulling on my nipple rings. They seemed to fascinate her. She pulled my head up and drove her tongue into my mouth. "Let me taste my own pussy juices" she moaned. It felt like she was trying to drive her tongue down my throat. Soon, she slid off the table. When she got to her waist, she grabbed my balls and pulled my dick into her open mouth. I felt her teeth slightly on the shaft of my cock and then she began to suck hard. Her tongue was playing with the stud under my dick head and her hands were grabbing and squeezing my leather-bound balls. Slurping sounds were mixed with moans as she brought me closer and closer to coming. "I love the taste of prick and leather" she softly said. "I want that cock in my pussy now" she said standing up and leaning over the counter. "Fuck me from behind." I got behind her and slowly pushed my throbbing cock into her hot wet pussy. I pushed and pulled while grabbing her heaving breasts. I was going to come hard and I started to ram her as hard as I could. My thighs were smacking against her hot ass when the come blasted out of my cock into her hot box. My cock had swelled so much I felt like the harness would burst. She tensed and arched her back. I stood still and felt the walls of her pussy contract around my still hard cock. "Your dick is still hard" she whispered. "Fuck me in the ass." I took some of the jelly she had used on me and put a glob of it at the entrance to her tight ass. Pushing my leather bound cock slowly into her took a long time but then I was in. It felt like a hot vise. She started to moan again and her hands went between her legs. She was grabbing and pulling at her cunt lips and saying softly "yes, fuck my ass baby." "I love to get backdoor sex." It took longer for the pressure to build this time but I found myself again blasting hot come into her hard body. She finally relaxed and sagged against my body. When she got her breath back, she turned around and put her arms around my neck. "Tell me, does a sex slave leave a lady with all this gooey cum running out of her pussy?" "Not if you order me not to" I told her staring into her lusting dark eyes. "Then get down there and clean me out" the horny Doctor Fisher told me. I picked her up by her waists and placed her ass on the counter. She leaned back and I dove into her hot sticky cunt. I licked and sucked at the cum that I had just pumped into her. When her pussy lips were clean and shining, I stood up and gave her a sloppy kiss so she could get a taste of what I tasted. "I guess you'll have to come back to finish this physical another time." That prospect sounded good to me but I knew that when I told my mistress what had happened that she would use this as an excuse to punish me. Of course, this is the reason I would tell her.
