I am still not sure how this happened and to some degree I am still in shock. I have been married to Jean for thirty years and although our sex life isn't perfect I had no idea until recently that Jean thought otherwise. I found out by accident when I returned home early from a golf match and found that my wife had girlfriends round for afternoon wine and biscuits. Not wishing to disturb them I went to the kitchen but couldn't help overhearing their conversation. I was quite suprised at the gist of their discussion as it concerned sexual relations with their husbands. As Jean is quite reticent when discussing sex I was amazed and concerned when she started discussing our sex lives. Far from being satisfied with it, Jean explained to the others that I was quite small in the penis department and it was a long time since she had had an orgasm during sex. I could hear her friends sympathising with her and one of them 'Sue' she would talk to her later to see if she could help. There was now much laughter and as I slipped away I was hoping that it was just the drink talking. Later as we prepared for bed Jean must have sensed I was upset as she asked me what was wrong. I had to admit that I had overheard her conversation and I asked her if she had meant what she had said regarding our sex lives She said that whilst she regretted what she had said, and it was due to the drink, she was being honest and was sorry that I had overheard it and been hurt. I asked her what was the main cause of her concern and she said that I didn't get properly erect anymore and my penis was so small she hardly felt it, and it never gave her pleasure. We discussed what we should do and she said that one of the girls 'Sue' had suggested that she goes with one of her ex boyfriends who was extremely well endowed. I said to her that she should never do that but she said that she had already asked Sue to arrange it. Although upset by this I was suprised that my cock was getting hard and this was noticed by my wife who said perhaps you'll enjoy watching me get fucked. I asked when the meeting was to take place and she said it was to have been at the weekend in a local hotel but now that I knew about it, it could be at home. I asked if she wanted me there but she said 'no' I would have to book into a hotel for the night. When Saturday arrived Jean was really excited and she had bought new underwear for the occasion. I told her it was not too late to cancel but deep down I was hoping she wouldn't. She took ages getting ready and at the allotted time there was a knock at the door. I answered it to find a good looking black man in his late thirties accompanied by Sue who made the introductions. His name was Jerome and he was really pleasant and from the conversation you would never have guessed the reason for his presence. When he was introduced to Jean he kissed her on the cheek in a manner that seemed to promise more. I asked if she would be alright and she said not to worry and I had better be going and she would see me in the morning, Sue said that she would also go and we left together. Once outside Sue told me not to worry as Jerome was a gentle person and he would make my wife very happy. I had a sleepless night imagining what Jean was doing although I have to admit I had a wank at the thought of it. The following morning I rang Jean who said that Jerome had just left and it was alright to return home. I found my wife still in bed and from the wine glasses and the disarray around the room I guessed she had had a good time. I asked how it had been and she said brilliant do you want to see and she opened her legs so that I could see a very red and swollen vagina. She was laid on a towel which was soaking wet with what I guessed was a mixture of their juices. She said that before he left Jerome had fucked her one last time. I asked if he was as big as she had expected and she smiled and said he was enormous and had cum gallons as could be seen on the towel. She said that she was seeing him again the next Saturday and that Jerome had agreed that I could be present. She asked if it excited me to see her like this and that I could have a wank and she laughed when I took out my cock and started to masturbate in front of her. She said that Jerome's cock was three times the size of mine and this seemed to send me over the edge and my sperm soon joined that of Jerome's on the towel. In the days before Jerome's next visit we even had sex although it seemed that this was guilt trip on behalf of my wife as she didn't seem to enjoy it, and I found that she was not as tight as usual. Saturday came and Jerome arrived at the allotted time, once again he was very pleasant but this time there was no peck on the cheek but a full bloodied kiss for my wife. After small talk Jerome and my wife got a glass of wine and went to the bedroom and I followed about ten minutes later. They had both removed their clothes and Jerome had his hand on my wife's breast and she was holding his swollen cock. I was shocked at the size of it. It must have been ten inches long with a massive mushroom head which was leaking lots of precum. My wife felt the tip of his cock and quickly stooped down to lick off the precum and suck out any remaining juice. Seeing me standing there she told me to undress and stand next to Jerome so that our cocks were touching. This really demeaned me as I found it was true that Jerome's cock seemed three times the size of mine and he said to Jean that he could now understand why she had been so frustrated. Jean and Jerome then got into the sixty-nine position with him on top. This gave me a perfect view of his massive egg shaped balls that hung down in a loose sack. I compared them to mine which were small and did not hang down at all. My wife noticed me looking and said why don't you feel them and Jerome said go ahead and I tentatively cupped his balls in my hand. My wife was now gasping and asked Jerome to fuck her whereupon he gave her a kiss and positioned himself between her legs. I found it difficult to believe that she could manage such a cock but he positioned himself at the entrance to her vagina and she put her hand down and guided him in. He was very careful and inch by inch he entered her until he was fully inserted. He stopped then and my wife moved her body so that she was the one doing the lovemaking as this was what it surely was. I was by now rock hard and couldn't resist wanking my cock which made my wife smile. After a while my wife said she wanted it doggy style which was her favourite position, and as they changed position Jerome said I should get underneath my wife so that I could see what was happening. He also said that I should squeeze his balls as he came as he liked this. I positioned myself underneath my wife and had a perfect view as he forced his cock up my wife's vagina. As they moved my wife was having multiple orgasms and before long Jerome indicated he was about to cum. My wife now told him to give it to her and forced herself back onto his cock for maximum penetration, this sent Jerome over the edge and as instructed I squeezed his balls as he emptied them into my wife. He seemed to cum for ever and I could feel the movement as his genitals contracted with each load he deposited. He remained in my wife for several minutes and when he withdrew his softening cock flopped onto my face. This amused him and he told me to suck it and I tasted the mixture of their cum. As I moved to get up my wife lowered herself onto my face and pretty soon I was swallowing large amounts of Jerome's cum. When I was eventually allowed to get up Jerome and my wife were laid in each others arms. She noticed that my cock was still hard and said that I should stand next to them and have a wank. As I did this Jerome put his hand between my legs and pulled sharply on my balls. My wife said I know what he likes and she told me to bend over. As I did so she inserted a finger in my arse and moved it back and forth whilst at the same time Jerome squeezed my balls. My wife told me to continue wanking and to tell them when I was cumming. Every now and then Jerome would have a pull on my cock and it was not long before I told them I was on the verge of shooting my load. My wife now inserted another finger in my arse and Jerome squeezed by balls hard. This sent me over the edge and I had the best orgasm I had ever had. Jerome and my wife spent the night together and the following morning I was made to lick her out whilst as a joke, Jerome tried to see how many fingers he could get up my arse. I am still not sure where we go from here, for in some ways our sex life has improved. I guess its a wait and see situation but Jerome seems to have become a permanent weekend fixture.
