This story may be a little long, but like the fantasy the real thing was worth the wait. With Julie always being up for taking cock, and with the stress of my job perhaps taking its toll on our sex life, I decided to spice things up in the bedroom. Mutual masturbation is guaranteed between us when we are both too tired but still need a good cum. Realising that Julie\'s pussy was not getting serviced as often as it needed I started bringing another cock into the bedroom in the form of imagination of another man taking her from behind. As we lay facing each other I would gently rub her wet pussy whilst she tugged furiously on my dick. Moving my hands onto her arse cheeks I would pull her bum apart revealing her wet gash, and spread it further open before telling her that there is a guy with a big cock standing behind her and he wants to put his big cock in her opened cunt right now. Julie would wank me harder hearing this, and I would spank her bum, telling her that she is a dirty bitch, but does she want his cock. Yes she would reply. Reaching to put my fingers inside her from behind I tell her the other man is touching her and he is going to fuck her now. Do you want his big cock........always Julie would say YES! I would at this point normally shoot my spunk all over her, then taking some of my cum rub it into her pussy and clit and she would have an immediate and explosive orgasm. I would finish my self off by getting Julie onto all fours and fuck her from behind and empty my next load of cum inside her. Lying beside Julie one night after doing this I asked her if she enjoyed the fantasy. She said she did and I told her I liked the thought of seeing her take another man\'s cock whilst still pleasuring me. Julie started to touch herself, but said nothing. She continued wanking as she lay, her legs tightly closed. I kneeled at her face and wanked my cock into her welcoming mouth and told her she was so beautiful that she should share her fantastic body and let someone else make sure that her pussy gets the pounding it so rightly deserves. Julie came quick, and licked me to cum over her face and mouth. We cuddled and fell asleep. Our fantasies continued in the bedroom over the next few months, and Julie became more willing to involve \"others\" in our sex life fantasies. Julie had at first worried that by her wanting someone elses cock I would think she did not love me. We started having sex outdoors, but we were never so brave as to carry on when other people were about. Last weekend however brought a change in our lives. Julie and I were going out on the Friday night separately with our own friends. Julie had 2 of her pals staying over, Kim and Fiona, whilst John, a good friend of us both was staying in the other guest bedroom that night. During the evening I got chatting to John about him and Kate (his partner) and were they getting married etc...and he came back with saying that he thought the relationship was over. He said that Me and Julie looked great together and envied us being so happy. I assured him that we were strong but that there comes a time when things aren\'t so great, and that even our sex life has been needing some fantasy and role play to get some spice back. Mike came back to say that Julie is gorgeous. Lovely tits and ass, and when she wears denims her camel-toe pussy mound looked meaty enough to eat. I laughed, but agreed with him. I told him about our fantasy of Julie being taken from behind by another guy whilst she pleasures my cock. I told him that Julie cums by the bucket when we do that. I hold her pussy open and tell her another man\'s big cock is going to fuck her. Just the thought of it happening has Julie cumming I explained. John jokingly said if I needed a volunteer look no further, and laughed gauging my reaction. I told John I may like to take him up in his offer, could we suck it and see? We arrived home about 2am. Julie and the girls were getting ready for bed, so I kessed Jules goodnight and told her I would be up soon for a cuddle. Julie snogged me hard and said she would still be awake. I got John a beer and sat with him for 5 minutes getting back to what we had talked about earlier. I said if he wanted he could stand and wait at our bedroom door, and if Julie becomes so horny that she would take another guys cock then to move in behind her and become that guy. John asked if I was sure. I told him that the fantasy gives amazing orgasms and I would like to attempt the real thing. I told John that Julie really likes him so there is not a problem with intrusion..............John agreed he would see what happens. We both went upstairs. In bed Julie started kissing me and quickly reached down to my cock. I was already hard and Julie asked me if I was ready to give her a good pounding. Sensing John at our bedroom door I told her that I was not going to fuck her unless she exposes her bare arse. I told her I wanted her to show off her opened cunt from behind to the guys (imaginary) behind her who want to fuck her hard. I rubbed Julie\'s pussy, she was wet and she trembled. Julie bit my right nipple and said Yes that she wanted fucked by them. I told her that they have gone. Where have they gone. Away I told her, but John is here and he is looking at your gorgeous arse and wants to fuck your pussy from behind. Does he have a big cock she asked. Oh Yes, his cock is long and thick and he will stretch you. I touched her opened fanny and I could feel Julie flow. Do you want John to fuck you. Oh Yes she said, still thinking this was fantasy. I slapped Julie\'s bum and told her she was a dirty bitch for wanting another cock. I want John\'s big cock in me. Do you really? Yes! Are you sure? Yes! Do you want me to get John Bring him into our bedroom and fuck you. Yes! Julie was cumm was building, and I told her he is standing naked and is going to touch her bum. At that John stroked Julie\'s round bum and then slid his hand through her moist pussy to her bumhole. Julie came hard. I told her it was okay can John fuck her. Yes! John entered her and Julie lifted her back up to dictate the length and speed of John\'s strokes inside her. With both hands she stroked the front of his thighs. John reached around and put both hands on her small firm tits and squeezed her nipples hard. Julie then went down onto my prick and sucked it hard whilst wanking me. Are you okay babe I asked her, to which she replied she was. Julie told John to cum inside her. John\'s thrusts got harder and faster and just as he was about to cum Julie reached down through her legs to squeeze John\'s big balls. John flooded her making Julie orgasm again. The noise in the bedroom had alerted Kim and Fiona, who were sharing a room. Julie was slumped on her back whilst I wanked over her tits and pussy. Fiona had her hand over her pussy and was obviously wanking, whilst Kim had gone over to John and had started sucking his cock back to erection. Kim was frigging herself whilst doing John. Fiona had moved over to the bed and was stroking Julie\'s wet cum soaked body. Fiona continued wanking as she sucked at Julie\'s nipples, before Kim parted Fiona\'s legs and guided John between them into her cunt. Julie started wanking furiously herself and lay besides Fiona as she was getting fucked by John\'s big dick. John sprayed his sperm over both girls, whilst Kim brought herself off with a little help from me sucking her tits and fingering her bumhole. Party over me and Julie stuck to each other in bed....shattered. John left to join the other girls in their room. How do you feel I asked Julie. Good, she replied. Would you do it again? With John Yes. In the morning we were all a bit sore and hung over, but agreed to keep our secret safe. Well I can\'t keep that secret. John is willing to do it all again, when the timing is right, and Julie is very open to the idea of other experiences outwith fantasy as she enjoyed the reality just as much. Secret spilled on SH, but I want to share Julie and fulfill her sexual desires which were always there. Julie was just afraid of upsetting me should she voice them. Watching Julie getting pounded from behind by John\'s thick cock, and seeing her tits swing and bum recoil was heaven. The memory of that night as written above makes me want to do it all over again.
