As often happens with true stories the beginning always leaves an immoveable imprint in the mind but if it irrevocably  shapes the future I am not qualified to answer that, readers are free to make their own minds up.

At twelve hormones were rushing through my body and naturally I thought my first uncontrollable erections were unique to me and kept that part of my life a secret. My best playmate was a neighbouring girl, my age, who was tomboyish and great at joining in, shall we say, boys only games so we were inseparable. Her uncle was great friends with a local man the bread and showed rabbits and lots of folks in the area saved scraps of vegetables that we often delivered to him. We enjoyed being in the large shed that he had on an allotment and became regular visitors for an hour in the early evening after school and eventually we were asked if we would like to help him one Saturday afternoon.

It was great fun changing the hay in the cages and giving the rabbits food and we were all laughing when at last we had finished. Rabbit-man told us to take our clothes off and give them a good shake and as he was old enough to be our grandfather we thought nothing of it and were soon stripped to our pants and doing his bidding. We both looked at each other and reddened however when he said we should shake our pants as well and our reluctance made him laugh again and tell us that it was ok as it would be our secret forever.

We just stood stiff, looking at each other and by that time we were crimson with embarrassment so he went to the girl and gently eased her last protection down while telling me to join in. I just stared at my first naked girl as I very slowly dropped them, displaying an erection that made her giggle and point to it, he telling her that that was what happened when a boy got excited. He sat on a bale of hay and sat her on his knee, patting the bale and telling me to sit and as soon as I did he ran a finger up and down her slit and she squirmed and giggled as she said it made her feel funny. 

He carried on for a while and the parted the flesh and showed me what she looked like inside the pink flesh exciting me even more and I marvelled at the small hole at the bottom and an even smaller funny looking swollen bit at the top. She was having a good time and did not take her eyes off of me, telling the man how big my thing looked on such a small boy. Rabbit-man was beaming now and left the girl and put two fingers an his thumb onto my penis and drew the sheaf of skin right back along it, showing the mushroom shaped end to the girl and making her blush this time as she stared at it. It took him no time at all to move his hand back and forth along my flesh and cause a very funny feeling to well up inside me, making the sac below my penis throb and the tube of flesh swell and pulse as a few blobs of white sticky fluid ooze from it.

Neither of us spoke as we went homewards, too embarrassed to tell each other what we thought about what had happened with the man but we were at our usual meeting spot on the Monday evening and hurried to the shed. From then on for the next couple of months things were much the same, I liking our Saturday visit's the best though as we two youngsters were naked when the man played with us. He was now getting most of a finger inside the girl and I was all a tingle as I watched ready for when he masturbated me and the stuff that came from me increased and started to shoot quite forcibly, much to the delight of the girl. There was to be a change late in the summer as rabbit-man told us he was going on holiday and the man who had the next allotment to him was to look after the rabbits for him and he hoped that we would help him at the weekend. We obviously wanted to keep in his good books so agreed, especially as we were not to visit during the week.

We were at our best on Saturday afternoon, wanting to impress Mr. Green with our knowledge of looking after the rabbits, cleaning the cages putting the fresh hay and food in and at the end we were both exhausted but laughing and happy. The man was grinning from ear to ear and he told us to clean ourselves up as usual, laughing at our gaping mouths but quickly telling us he knew all about it and he could keep secrets. I was very cautious and not sure what would happen with a new man, the girl on the other hand giggled and was soon naked and showing herself of to the stranger. He took no notice of me and laid her along a bale, running his hands over her body and almost drooling as she eagerly spread her legs in this new position gasping with excitement as he started to finger her. He told me to hurry and sit on a bale to watch so I too stripped and sat, quietly watching as his finger disappeared into her hole, happier when she wriggled and sighed with satisfaction. 
I perked up when he started working in and out of her as she writhed, gasped and let out a squeal that changed into a long gurgle as he went quite fast but I realised he was not hurting her. He paused for a while to let her calm down, the puffy lips of her crack though still pouted open and I was still thrilled with the sight of her and my penis was very hard by this time so I played with myself adding to my own pleasure. He pushed the finger right up her as he restarted and as she gasped his thumb went to the swollen lump at the top of her crack and he waggled it across it and then up and down. All the flesh of her body rippled and ooohhss! and aahhss! escaped from her lips between pants as she wriggled her bottom on the bale and even when she squealed and gasped for breath he did not let up.

I wondered what was happening to her insides but my attention soon focused back on her nakedness as she lifted herself right off the bale and with a loud scream thrashed about so much she nearly fell to the floor. The man removed his hand and watched her contortions and with a broad smile calmly told me she had just had her first orgasm. I watched eagerly as an almost unconscious girl gradually came back to normal and was obviously more pleased than frightened and she let out a long sigh and looked at us both with a weak smile on her face and I think neither of us kids  really understood at that moment what had just happened.

We left and as we walked down the path she was trying to tell me what it had felt like when the man played with her like that, giggling as she said she wanted to play with me like rabbit-man did. I was all for it, still excited at what I had witnessed and we saw a small shed that had no lock on it and as soon as we were inside she pulled my shorts and underpants down to reveal my already swollen penis. She was giggling with pleasure as she slid the foreskin back and had a long look at the bell shaped end sporting the tube of hard flesh then as she worked on it asked if she was doing it like the man did. I was gasping with pleasure but managed to say it was even better and she gleefully carried on until with a long moan jerked and pulsed as my sticky liquid spurted out onto the floor. It was a happy and laughing couple that ran home, both itching for the next weekend to come.

We were very expectant from the moment we arrived and soon set about the chores, wanting the fun to begin. Mr. Green thwarted our eagerness as he did not prompt us to undress when we had finished, instead he told us he was taking us to his shed for a change. It was different to the other one and half of it looked more like a sitting room and he laughed at our surprise, telling us this was where came to get away from his wife. There was even a large curtain covering the window and one wall and he said he would show us why it was like that when we were undressed. As before he took little notice of me but looked longingly at the naked girl then, producing a Brownie box camera said he wanted her to behave like an adult while he took some pictures of her in front of the curtain.

She danced and pranced about sat, lay exposing herself to the lens fingering herself when he asked until he was satisfied and put the camera away. His hands were all over her body at last and he did much the same to her as last time except every time she was very worked up he stopped short of tipping her over the top. She was bathed in sweat after fifteen minutes or so of this treatment and begged him to make her feel funny and at last he brought her to a body wrenching orgasm. Her panting and moaning lasted as long as the shudders that played over her naked flesh until at last she sighed deeply and began to relax and I knew how much of a thrill she got from having a man do this to her.

He was obviously not satisfied yet and put me at her side, kneeling me down and telling her to wank me like rabbit-man did and make my spunk shoot. Now we both knew what these words meant from older boys and girls who liked using them when others were listening so with a smile she took hold of my already hard penis and played her hand up and down its length. The man looked happy and his hands gently stroked her belly, inner legs and even her slit but he did not attempt to push a finger into her this time. It was my turn to moan and gasp as my peak quickly rose and a happy girl watched my ejaculation spurt over her belly and slit.

I was pensive on the way home, telling her we ought to stop going before someone found out about what we were doing, she though said rabbit-man would be there next time and she wanted to tell him what we had done. I was still not keen but she said she would be to frightened to go on her own so I must go with her. I relented and promised to meet her the following Saturday and we parted, she smiling happily at my change of heart and as I slowly walked home had still not convinced myself that I would turn up.
I dragged my heels as I went to meet the girl, hoping that she would get fed up of waiting for me and go home but she was there, all smiles and looking forward to being reunited with rabbit-man. He greeted us warmly and told us that he had been there since early morning and had already done the hutches so we would have a lot more time for fun. There was no rush from him to have us naked and we just sat on a knee apiece divest of clothing from the waist down as he played with out genitals in turn. The reason for his slow start became obvious when Mr. Green arrived and we were soon naked then, much to the delight of the girl as she watched my erection grow as I looked at her.

Rabbit-man went to the girl first and enjoyed fingering her and making her squirm and squeal opening her up so that we could look at her pink inner crack and finger filled hole. Mr, Green was eager to take over and as I sat on rabbit-mans knee he manipulated me while we watched the other man take the girl to her peak, once more resting so that she took a long time to orgasm. Long before she came to her climax I felt my mans penis swelling in his trousers and he adjusted me so that it was in between the cheeks of my bottom and the first pangs of uneasiness crept into my stomach as he had never shown these signs before. The girl came to a noisy orgasm and thrashed about on the bale as Mr. Green told her to let it all go, obviously excited by the strength of it, panic set in with me as rabbit-man pushed my naked body along his hard flesh and I squirmed, more to get out of the way than to give him encouragement.

Mr. Green told his friend to put me near her and wank me so that my spunk shot over her and it did not take him long to bring me to ejaculation and her belly and crack became the target for my deposit. The girl and I were both recovering but I heard him say that she was definitely ready for cock, rabbit-man smiling in agreement. I did not enjoy the walk home especially as my friend was her usual buoyant self after enjoying all had happened to us both and I did not tell her how rabbit-man had behaved but knew in my heart that I would not visit the shed again. Fate took a hand and I passed an exam for one of the city schools and lost track of most of my local friends and it was to be quite a few years before I came across her again.
