Julia and I had been together for a few years. Besides being intimate with each other, we were also best friends. We had tried all the usual sexual stuff - missionary, her on top, riding her from the back, oral, and so on. We also had fantasised about other things, threesomes, and gang bangs, but never quite mustered up the courage to take these things through beyond some play acting with each other. We had both become very busy with our work lives and did not have much time to be with each other. She and I both worked late and were not able to give much attention to the other. This normally would lead to a couple splitting up, but it ended up being a great thing. I got to live out my biggest fantasy and we now have the best sex life in the world. The following is what led to this new life for both of us.
I had come home from a long day and week at work. All the lights in the house were off, which was surprising since I knew that Julia had been home for a few hours and that is was Friday. I went back to the bedroom and found Julia asleep in bed. This was also surprising because she is usually awake to greet me if I get home after her. I just thought that she had had a long day and was exhausted when she got home. I was pretty tired too, so I decided that I would just go to bed with her.
I pulled back the covers and admired the beautiful body that Julia had. She was lying on her back with her legs slightly spread. I climbed into bed and snuggled up next to her, she murmured quietly in what I presumed was acknowledgment of my arrival. Being a typical male, I got aroused feeling her naked flesh and I started to lightly caress her.
Eventually my hand passed over her thighs and brushed against her mound. She was soaking wet. I guessed that maybe she was awake and was just enjoying the message, but she was still passed out. I thought "what the heck" and decided that I would go down on her and maybe wake her up through pleasure. My face made it's way down to her pussy. I started to lick up the side of one of her lips. I circled my tongue up and then down over her clit until my tongue was in her pussy. I stopped for minute realizing that something seemed different. She tasted great and had a deep musk scent to her pussy, but the only time that she smelled and tasted this great was after we had made love. Someone else had fucked my girlfriend!
At first I was upset and felt hurt. I realised though that I actually enjoyed going down on her after another man had fucked her, this had been one of the fantasies we had talked about in the past so I was really turned on. I became aroused again and put my face right back to her bush. I worked my tongue as deep as I could into her pussy. After a few minutes of this, her hips began to move, so she really was awake now. I felt her hands grab the back of my head and bring my face more into her crotch. Julia began moaning and had a great orgasm. She quickly pulled me up to her face and began to kiss me deeply. My dick quickly found her hole and I began to hump wildly.
I was having the time of my life. Julia's lover's semen was being shared between our mouths and my dick was being lubricated where another man had recently been. After a couple minutes of this I could not hold back any longer and shot my hot cum into her already full pussy. This had to have been one of the biggest orgasms I had ever had. I pulled out of Julia and rolled off of her. I was truly physically exhausted. Julia moved closer to me and into my arms. We both fell asleep feeling great.
The next day I woke up and found that Julia was not there. I started to think about what happened the night before and how to react if it was brought up. Even though Julia and I shared the threesome fantasies and even used fake cocks on each other, I was not sure how she'd react to how turned on I was about another man's cock being inside of her. I decided to just let things come out however they might and not worry about it.
I got up and went to the kitchen. Julia was standing there in her silk robe. She smiled and came over and hugged me. Julia told me how great I was and that she had really enjoyed me the night before. I wondered if she knew that I knew she had slept with someone else. Did she love last night because of me accepting her fucking another man or just because I had been good in bed? She answered my question without me even having to ask and completely shocked me!
"Darling, I want you to know that I love you and always will. I just hope you can accept that I need to fuck to feel good about myself, and if you and I are to busy to make love, then I will find someone else to keep me satisfied in the bedroom. I don't want to break up or anything, I just want more sex. Obviously you knew that I had been with someone else before you last night. I even saw the broken condom and wrapper lying on the ground when I woke up. It was a real turn-on having you lick my pussy after another man had cum in me. I hope you don't mind if we can do it more often. I think you would like Brad. He is Australian, he's absolutely huge and he is bi. I know you had messed around some when you were younger with guys and had experimented, so I guessed that if you were cool with it, we could all have each other in the bedroom."
My jaw just flopped open, I tried to speak but nothing came out, after a short pause Julia continued
