Brother and Sister

My little brother Billy is two years my junior and of course I've always loved him, though at times he is ridiculous with the things he does and his rough-house play. When we were little Mum explained to me that it was only because he's a boy, and boys do silly things because of their testes. Mum raised us by herself. I never knew my Dad, and Mum always assured us we didn't miss out on anything by not knowing that arsehole.

Mum never discussed her sexuality with us but I know she has definately had relationships with other women, and no men that I know of. She was definately off men.

So I grew up with no exposure and developed a fascination for penises and testicles, and in particular - Billy's testicles. The other boys at school would never let me anywhere near their privates. But Billy was, I think just as fascinated as me. He has always let me touch his testes even though sometimes I accidentally hurt him, he always forgave me.

For example we were younger, I was much bigger than Billy but sometimes he would get a bit rough when we were playing and would wack me or hurt me, I would just reach down and grab his little balls between my fingers. If he didn't stop being ridiculous I just squeezed them enough to make him cry. I remember one day after I came home from school Billy was carrying on, Mum had the shits with both of us and Billy hit me hard on the head, he knew what was coming and tried to get away but I caught him by his collar, grabbed his nuts in his shorts with my right hand and asked him "what now little man?" Well he managed to get another one in with the back of his elbow, so I gave him a real good squeeze. Poor Billy dropped to the floor crying so hard that Mum came in. She was cross at both of us, so I told her what had happened. Billy was still wimpering so we had a look at his testicles to make sure they were alright, he said they were sore but mum said that they were OK, and explained that I shouldn't sqeeze my brothers testicles so hard even if it does quiet him down. We put Billy in bed and pampered him but I think he was bunging it on.

Anyhow Mum never really minded me keeping him under control in my special way, and more than once I heard her threaten to squeeze his little nuts, though I don't think she ever did.

Around this time, our pup Roger started causing mischeif whenever we weren't home, chewing our stuff and barking constantly but Mum didn't muck around with him, she took him to the vet and got his nuts cut out while we waited. She explained to us about testosterone and how roger will be sore for a few days but after that he'll be a nicer dog. She was right.

As Billy got a little older, about 9 or 10, when we'd get home from school he'd take off his jocks and put his shorts back on, then sometimes he'd annoy me until he got his just punishment - I'd grab his nuts and pull them out of his shorts, especially on a hot day, and find out how far he wanted to go and tease him that one day I would fix him up like roger. I was a bit ruthless with my punishments and occasionally he'd end up in tears, but he always forgave me once his testes stopped hurting. I always enjoyed making him beg, and sometimes I noticed that Billy got a stiffy while we were sorting out who was boss.

A couple of years later found me in High school and Billy still a junior. We started to develop a game when Mum was out. I'd take off Billy's shorts, grab his balls and get him to do things for me like brush my hair, and to make it better he would always have a stiffy the whole time. I was fascinated. Then I realized that I could tie a piece of string around his nuts and still have 100% control over him. This gave him a wider range and made him heaps more useful. For example he could clean my room, or give me a bath. One night I was in my bath, and he was supposed to be washing my hair, I had my end of the string in my hand under the water when he stopped so I gave him a good jerk to snap him back to attention, still nothing, I wiped the soap of my face and looked up at him just as he came all over my breasts which were starting to develop and I was very proud of. Then he explained to me he didn't feel like playing and untied the string off his nuts. I was excited by this and after he went out I fondled my breasts and masturbated in the bathtub.

Billy was a darling from this time on, whenever we had a chance I would tie him up by the nuts, I could make him do absolutely anything and when I was finished with him, I'd pull hard on the string and make him masturbate himself in front of me. If he begged nicely enough or promised me something sometimes I would let him see my breasts or my fanny while he wanked.

Mum was amazed at the control I always had over Billy, but warned that this would be short lived. I may be bigger now, but soon his testosterone would take over, Billy would soon be a lot bigger than me and all he will think about is women and that I would have no control over him at all. It all comes back to the testicular problem she said.

One day I found him wanking in his room with a rubber band tightly around his balls, so I grabbed hold of them and jerked him so hard that he stopped, I took him to my room and I also tied my string around his balls which I noticed were already turning an exquisite purple colour and I made him tell me what was going on and why he should come to me when he wanted to masturbate. He explained that all he could think about all day was my tits and my fanny and that he wanted to be free of his cursed nuts like roger our old dog. Then he explained about how an elastrator was just a tight rubber band and how it worked. Wow, so simple, and he would never grow bigger than me or want to be with other girls. I wanted him castrated too. Billy was a darling and I wanted him to stay that way. I could see his rubber band was getting painful, so I pulled off my skirt and panties and made him masturbate. He seemed to come even more than usual, then I untied him and took off his band.

Next day I bought and elastrator and bands from an agricultural suppliers shop on the way home from school. We were both so excited when I showed Billy what was in my bag when I got home. We just kept looking at each other all afternoon, he'd come to my room, then I'd go to his. Billy wanted to fit it straight away but I wouldn't let him. After tea I made him wash my hair while I had a bath, and then I fitted the rubber ring, it was so easy! He was already hard in anticipation and I made him masturbate while I toyed with his testicles. We all went to bed and I snuck into Billy's room. He said his balls were starting to hurt, and let me have a look. Yep, they sure looked sick, I asked if I could help and he said maybe if I gave him a bit of a rub... so I started to rub his penis the way I'd seen him do so many times, he got stiff imediately and I played with him for a long time until eventually he came again. Then he said his balls really ached. Billy was in so much pain I decided to get Mum. Mum was pissed off when I told her what we'd done and when I told her the band had been on for 3 or 4 hours she rang the doctor. We took Billy to the hospital and the Doctor had to amputate his testes.

We're older now, we love each other so much and Billy says he wishes he was a bit bigger than me so he could bash me up, but he's only joking. He's definately the nicest man that I've ever met.
