He got to watch from the hallway, when he came over on weekends to screw her: the guys was built and had incredible staying power. Over time, Bob was getting to fuck Dianne less and less. She liked it best when he went down on her after dates and would sometimes jerk him off while telling him about how the guys really seemed to enjoy fucking her pussy.

She told him it turned her on when the guys would shoot their sperm into her. She thought about how he would soon be going down on her and licking it out. She said it turned her on to cuckold him and wanted him to try not having sex for awhile. He could lick her pussy, but no fucking for him; only other guys would get to screw her now.

Bob went along with it, but found it very frustrating to watch some guy fuck his wife, cum inside her, than only get to lick her pussy himself. After a year of this he complained to Dianne that it was not fair that he was not getting to fuck his own wife, but other men could have her any time they want.

She knew it had to be hard on a man, and had a solution. If he would get sterilized, she would let him fuck her all he wanted. They had been talking about having a child so this was a suprise to him. Her plan was to get him fixed, go off birth control and take her chances with getting pregnant by the other guys. This way he could fuck her, but not be able to knock her up. She would enjoy cuckolding him by letting other men father their children!

Bob was so frustrated he eventually agreed to her offer and she made the arrangements with a woman doctor a friend had told her about. The night before his surgery, Dianne joined him in the bath tub and shaved his cock and balls. She joked about how he would be shooting blanks after tomorrow and other, whole men would have to father their children!

The next morning she drove him to the clinic and went in with him to see the Doctor. Dr Mary was younger than he expected and very beautiful. She had him strip right away and lay back on the surgery table. He got an erection as the nurse spread a disinfectant over his entire scrotum. The doctor injected a pain killer in several places around his sac and assured him he would feel nothing. He was suprised when the nurse straped his arms and legs to the table, she reassured him saying they did not want him to move at the wrong time. He felt very vulnerable with his pride and joy fully exposed as these women rolled a table with sharp scalples and clamps into place next to him.

Dianne held his hand and reminded him that after his sterilization, she would let him fuck her as often as he wanted to. The doctor picked up a scalple and began cutting below his dick. He could not see what she was doing but watched as the nurse handed her clamps, sutures, etc. His wife watched intently and he noticed a video camera on a stand to one side, recording the event.

The doctor spent a length of time sewing him up and announced finally that she was done. She lifted a tray from between his legs and sat it on the table next to him. At first he could not understand what the two oval objects laying in it were, but suddenly realized that they were his testicles! His wife saw the shocked look on his face and told him that yes, he was now castrated! She said he would still be able to fuck, at least for a while and she would fuck him for as long as he could get it up. She told him that by the time he went totally impotent, he would not want to fuck anymore, because his testosterone and sex drive would be gone! Bob could not help but cry as they put his testicles in a jar for Dianne to take home with her.

She said several of her girlfreinds had brought their husbands to Dr Mary and they were now perfectly content to let other men satisfy their wives.

Bob was in a state of shock for the first few days. He would go to the bathroom and just stare at the bandage below his cock, where his balls used to hang. After a week, he went back to the clinic to have his stitches out and felt very humilitated as the pretty nurse worked on his castrated sac. His wife did let him fuck her that night and encouraged him to fuck her as often as possible the next few weeks. She loved to fondle his empty sac and tell him he was no longer a whole man anymore. She said it felt strange to get fucked, but not feel a pair of nuts slapping against her.

He soon started finding it difficult to get hard and she would just laugh when he went limp soon after entering her pussy. She told him his manhood was fading fast and to enjoy any erections he could get from now on.

After sucking on his limp dick for an hour one night, she told him he had to accept that his sex life was over and his dick was going to be useless from now on. From now on the only sex he would be having was to go down on her after a real man had deposited his sperm in her pussy.

She often had him drop his pants and show her girlfreinds his empty sac and limp cock.
