All the time we were together the two dogs stayed with us, occasionally trying to sniff us and always following us if we got up to go somewhere. Marija blushed when the smaller of the two actually got his nose between her legs and I began to realise there was a possibility that she might have done the same thing as me with this one, or perhaps both. You wont believe this but my first thoughts were of jealousy! After all, the big dog had made me cum twice and I felt he sort of belonged to me. But these thoughts soon passed because the smaller dog was actually trying to fuck her leg and she was doing her best to get him away. She was flustered and I asked her if he had done this before (meaning just being naughty). I cant remember her exact reply but it was something like, oh my god, please don't say anything to anyone!

We talked, and it turned out that not only had she experienced both dogs (at different times) but the person who taught her was none other than my older sister. My older sister, the sophisticated snobbish intellectual who my parents treated as a princess. We talked about our experiences and she had done a lot more than me. Apparently my sister had taught her how to get a dog erect, how to fold the skin around his cock back, how to hold him so he didn't loose his erection and then how to pull his cock through his legs so it was pointing backwards behind him. Why, I asked. So you can play with it she replied. Play? Yes, sucking it. Your sister puts it up herself like that and fucks herself on it. She tried to get me to do it but I didn't want to because its pretty big and I have still not had sex. I didn't know what to say, more because I realised my sister was not the angel she pretended to be but something of a pervert (these days I consider her to be enlightened and something of a role model).

It was about then that we realised we were on our own - the dogs had disappeared. I admitted to Marija that I felt really horny and wanted to try to do some of the things she had described. We grinned at each other and agreed to go find the dogs and help each other have a bit of fun. We looked everywhere for the dogs but couldn't find them. We didn't want to call out for them in case we raised suspicion so we turned to go back inside the house. There was a large outbuilding just before the main house that my uncle used to store stuff in and as we walked past it we could hear muffled voices and what sounded like my sisters voice repeatedly saying no, no no! We opened the door of the building but there was no one there so we crept around the back to the little room that was used for grain storage. My sister and cousins were inside but there was no window and the door was locked. Marija pulled my arm and we found large cracks in the wooden wall to look through. What I saw basically changed my life and to this day I still get flushed thinking about how it affected me.

There were candles burning in the small room. My two cousins were holding my sister over some sacks. She was completely naked and protesting. But, she let them bend her forwards over the sacks with her arse in the air, sort of on all fours but her tummy supported by the grain sack. They moved so one was by her head and one at her feet. She didn't resist any longer and my older cousin unzipped himself, pulled his clothes down and got his cock out. He moved to her face and she started to suck him. She looked like she knew what she was doing and I guessed this was not the first time the three of them had had sex together. I had sucked several boys at this stage but never seen anyone else do it and was fascinated. Marija tapped my on the shoulder and pointed. I thought that her other brother was about to fuck my sister so stared at him. Wrong. The two dogs were in the room with them and he was getting the smaller one up between her legs. My dirty bitch of a princess sister had actually spread her legs for him. I couldn't see what he was doing properly but now know he was wanking the dog's cock to get him ready.

Then it happened - the dog just lifted itself on to my sister's back and moved forwards with its hips, thrusting at, first, thin air and probably her legs, then into her pussy and the most amazing thing happened that I had ever seen in my life. He fucked my sister, hard, fast strokes, deep in her, she, crying out but still with my cousins cock in her mouth, the dogs thrusting moving her whole body with every push of his cock as he tried to get deeper in her. She cried out at each thrust and was gasping. I couldn't take it all in!! But the dog suddenly stopped and jumped down, walked around the room for a few seconds and returned to do the whole thing again. It mini-fucked her four times before sniffing at her pussy and licking his juice from her. My beautiful sister (I had now decided that actually she was a goddess) never moved, just rolled her bottom as the dog licked between her legs, and kept sucking on my cousins cock.

The boys swapped places. My sister took the second cock as if she was used to being spit roasted. Never moved an inch just took it in her mouth and started working at it. The older cousin moved the dog out of the way and fingered my sister and I thought he was going to fuck her, but no. After a few minutes he grabbed the larger dog by the collar and pulled him between my sisters open legs. He already had the scent of the other dog's sperm and started licking at her, to groans from my sister. Within a few minutes he too was mounted on her fucking her so hard my sister was being pushed forward on the sacks and the cousin was pushing at his arse to help him get deeper inside her. He mini-fucked her twice and then (I know now) he knotted her and my sister cried out, but stayed where she was.

I now know the dog was pumping large amounts of dog cum into her but I thought he was going to sleep and couldn't work out why she didn't just get up, and why she was moaning quite loudly. They brought the other smaller dog round to her face and I watched as they worked the dog's cock the way Marija had described it to me. That's probably when I fell in love with dog prick. The sight of it, red and pink, veined, fat and slightly pointed, spitting jets of cum everywhere, so primitive, so absolutely deviant, so disgustingly dirty made me go weak at the knees.

Marija and I were already masturbating, my panties thrown into the bushes somewhere, but as they moved the dog's cock to my sisters mouth and she just opened her lips and swallowed it without any hesitation, deeply, I felt the familiar sensation of an orgasm welling over me. The boys were moving the dog backwards and forwards, basically fucking her face with the dog prick and her pussy was locked onto the larger dogs cock filling her with sticky dog juice. I came, and so did Marija, though we managed not to make any noise. We continued watching till the dog dismounted and my sister let out a scary shout. She never took her mouth from the other cock so now I know she swallowed all his cum. The boys rolled her on her back and one started to fuck her, the other at her mouth. Marija and I crept away guessing that my sister was going to have them both, which was far less interesting to me than watching her with the dogs.

Back in the house we went to Marija's bedroom and watched each other masturbate. Its crazy but there were no inhibitions. What we had seen, what we had admitted to each other, meant that we were quite relaxed about doing things in front of each other, but not to each other (that came later!!). I asked her what had turned her on the most and she said watching my sister suck one dog whilst the other had knotted her. She explained knotting to me and it just sent my mind into a spin. You will probably wonder why, as a 15 year old teenager, I didn't get scared or was repulsed. But it was because I was so young that it had this impact on me.

I wanted to do everything my sister had done, and any other dirty thing besides, in fact the more dirty and depraved the better. Marija told me what it was like to suck dog cock and I desperately wanted to do it. We carried on masturbating as we spoke. I told her I wanted to do what my sister had done (but without my cousins!!) and asked her if she would help me. She agreed that we would ask our uncle if we could stay a few extra days and plan how we would go about it. That's when I realised I did not have my panties!!"
