I got married when I was 20. My wife had never had sex before our marriage. She also had not seen any other penis. That was a blessing for me because I have a small, little penis. My dick is only 4 inches when hard. I keep it shaved smooth so that my little thing looks even smaller. I am into comparing my dick with other guys and getting humiliated because of my tiny clit of a dick. I had no idea how my fantasies would impact my sex life.

My wife and I had sex regularly. I was able to stick my little boner into her pussy and we had a few kids so I know that my little thing was working. After 20 years of marriage we moved back to our hometown. It was a small place with about 2,000 residents. There was one doctor for the whole town. He grew up with us and we knew him well. His name was Kerry and he had two boys, ages 18 and 15. Their names were Keith and Stephen. His wife died 10 years after they were married. She got breast cancer and fought hard but, in the end, lost the battle. He had not dated anyone and regularly jerked off. I remembered seeing his dick in the showers at school. He had an extra large penis that was uncut.

One night when I was staying overnight at his house he invited me to jerk off with him. His dick grew to 10 thick inches. He compared our dicks and then asked me if I wanted to give him a Blow Job. I agreed and sucked his cock. He shot his load all over my face and hair. He liked my wife when he was in high school and dated her through high school. When she and I went off to the same college we started a relationship that got serious and finally ended in marriage.

A few weeks after we moved in I cut my finger with a knife. I needed stiches and my wife took me to see Dr. Kerry Randall. He saw the blood and worked his medical magic. I needed 4 stiches. The three of us talked while he was doing his work. He told me that I had stolen his first love. He told my wife that he enjoyed their time together and shared that he was heartbroken when she ended it to be with me. He instructed me to come in the next day for a complete physical. I went into his office late in the afternoon. No one was in the office. He explained that he worked late and couldn’t afford to have a full time assistant.

Then he took my blood pressure and listened to my heart and lungs. Then he told me to remove my boxers. He immediately got a good look at my tiny, shaved penis. He smiled and said: “I see that your male parts are no bigger than when we were in high school together. Both of my boys have bigger dicks than you. You could never satisfy your beautiful wife with that little thing. I bet she would be surprised to see how big I am compared to you.”

He felt my balls as he checked me for a hernia. Then he instructed me to lay on the exam table with my legs in the stirrups. Then he put on a glove and put a glob of lube onto his fingers. Then he moved his fingers to my anus. He pushed one and then two fingers into my ass. I could feel him make contact with my sensitive prostate. He informed me that he wanted to do some tests on my prostate and my testicles. He gave me 3 different medications to take home. Then he gave me a shot and told me to come back in 2 weeks. He scheduled appointments with specialists that were about 45 minutes away from my house. Then he instructed me not to jerk off, fuck or orgasm until after my appointment with him. I didn’t know if I could go without cumming for two whole weeks. I lived to cum and jerked off 4-5 times a day. I also fucked my wife at least twice a week. I loved getting off.

The doc must have read my mind because he looked at me and said: “I know it will be hard for you to keep from jerking off. If you get to the place where you just have to cum, then come over to my office or my home and I will give you something so that you can go the full 2 weeks without orgasm. It is essential that you follow my instructions and get help from me if you need it.”

After three days I was going crazy with lust. My dick was hard and dripping all the time. I couldn’t keep my mind off sex. I couldn’t stand it anymore after the fourth day. I went over to the doctors house at about 10pm. I knocked on the door and he answered it right away. He had just taken a shower and had a towel wrapped around his waist. He told me that his two boys were away for the week and that we were alone in the house. Then he went into his bedroom but did not close the door. “I know why you are here Mike and I can help you. Please go take a nice hot shower and then meet me in my home office and bedroom. There is a towel in the closet. You can use my youngest son’s bathrobe. See you in a few minutes.”

I showered and gave my dick and balls a fresh shave. I dried off and then put on the bathrobe. I walked to his room and entered. He was in his office chair working. I was shocked to see that he was totally nude. He heard me come in and got out of his chair. His huge, fat, long, uncut dick was hanging down limp. It was at least 6 inches soft and he had a thick nest of sex hair. Then he took me into his master bathroom and gave me an enema. When it all came out, he repeated the process. He told me that he could only help me if my anal cavity was clean. He gave me another shot in the butt and then numbed my penis and my prostate so that I could not get hard or cum. He instructed me to increase the doses of the meds he had given me and then invited me to give him a BJ like when we were kids. I don’t know why I did it, but I sucked him.

He came in my mouth and then kept his huge dick in my mouth so that I had to swallow his wad. Then he inserted a butt plug into my ass. It felt strange but good. He gave me a series of butt plugs that got larger and larger. He told me that they would help me from getting to orgasm.

After the two weeks were up I went back to the doctor and he brought me to orgasm with a prostate milking. I came as my prostate was pounded. He gave me another shot and then increased my dose of meds again. He told me that I was free to jerk off, orgasm and fuck. I couldn’t wait to get home and do my thing. However, when I tried to jerk off I was frustrated by how hard it was to keep hard. I also found it maddening to get close to orgasm but not be able to cum.

Over the next month my desire for sex continued to go down. I was neglecting my wife and she wanted to get fucked. My penis and balls were getting smaller and smaller.

Then at my next doctors appointment my friend Kerry told me that he had been chemically castrating me since my first visit. He told me that if I said anything to anyone he would tell about my cock sucking.

He came over to my house on occasion to fuck my mouth and then my ass. During one of those sessions, my wife caught me with Kerry’s big dick in my mouth.

My wife got fucked by that huge cock that very evening. He told her about my chemical castration and let her know what medication I needed to take to never allow my sex drive to rise again. I was chemically castrated by my doctor. He did it so he could fuck my wife.
