My Bisexual Teacher and His Wife SeXStoRY

So I just posted about the first time I made love with a man. We had been having sex for about six months when what I am about to write happened. He was married and he had a very attractive wife. She had red hair, a nice thick body and big natural tits. My cock always got hard when I saw her and sometimes when he and I were having sex I would sometime imagine her being there. I even asked him about the possibility of her joining us one day and he said no as she did not know that he was bisexual and was fucking the k** who lived next door. But this one day......I was home alone and was doing some chores in the backyard when he stuck his head over the fence and whistled at me. I went over and stood there with the fence between us and kissed for a few minutes and he wanted to know if I wanted to come over and go to bed with him. Of course I said yes and very soon I was in bed with him naked and in his arms. We kissed, sucked and had lots of foreplay (which he loved) and he was ready to put his cock inside me. I got on my hands and knees, he enjoyed fucking me doggy style the most, and slid his big cock inside all the way. After six months of sex, at least once a week with him, he was able to slide in me real good. My own six inch cock was hard as he thrust in and out of me. I was in pure lust and didnt hear the bedroom door open. I just happened to turn my head and saw his wife standing there totally naked. I was a bit shocked and was about to say something when he told me not to worry, that this was planned. He told me that his wife knew along that we had been fucking and was eager to join us but they werent sure about me. She said if I like her naked body and of course I said yes. They had a couple grown k**s and you can tell she had been pregnant. Those big fucking tits of her were just too much for me and her husbands big cock was working my ass soooooo good. She came over and lay down and spread her legs and I started eating her pussy. I had only eaten pussy twice before and never from a woman old enough at the time to be my mother....She tasted so fucking good and she got so wet it looked like water was being poured on her pussy. She then moved down and took my cock and put it inside her. I started fucking her. My ass and hips moving up and down pumping my cock into her pussy and also working her husbands cock. I couldnt believe this was happening and it didnt take me long before I shot a thick wad of cum into her womb. I guess my orgasm brought on his and just as I was coming down from ejaculating he emptied his balls into my ass. After.....I lay there between them and we kissed and fondled each other..... They became very close to me and I enjoyed them both, sometimes together, sometimes separately for a couple of years. They moved away but I sometime still hear from them.....
