About two years ago Carol and I agreed to let a thrid person [ male] to join us in the bedroom.I have been asked her to do this for sometime wanting to share her for the night with another man.She finaly agreed on if he was Black[ this sent me over the top ] I could wait for it to happen. I was 51 at the time and Carol was 50, shes 5foot 5inches tall, short blonde hair 34ff tits slim waist. Geoff was the man who came to the house we invited him back from a pub we go to out of town. We had been talking to him for serveral weeks and i noticed how he kept looking at Carols beautiful big tits, so we thought why not lets do it. It was a friday night when he came to the house he was 61 big strong and had acertain eye for the ladies, Carol insisted that she would be in control of the event and that I wasnt allowed to interfear as she was feeling real horny.We let geoff in to the house he was very smartly dressed standing 6ft we started talking and the drink started to flow. It was at this time that carol said thta we men should play strip poker and the winner will be taken to the bedroom so she can fuck the winner. Carol left the living room and after 10 mins returned waering a black strip dress, g string and had placed black tape over her nipples.I looked at Geoff and his face was a picture, my cock now was very hard thinking that in our home was the 61 year old blackman who was feasting his eyes on my wifes beautiful 34ff tits.I got up and kissed her telling her that I love her and that is she sure that she wants this to happen, oh you bet i do she replied.Carol started to walk around the room shaking her big tits at geoff and I saying that the one who loses their clothes can have me for 10 mins before the other person joins in. I made sure that geoff won and he kissed caol in front of me feeling the weight of her tits he told me to stay outside the door and not to enter until i was told. Off they went into the bedroom i stood outside cock in hand listening to the noise coming from inside.Carol was begging him to lick her pussy and make her cum saying how much she loves older men, it was then Geoff shouted to me to open the door and look into the mirror [ I could see the bed though the mirror ] . Carol was on her back and geoff had both of her legs in the air while geoff eat her pussy. He then made her sit up on the bed and she took his cock in her mouth, sucking it and looking at me thought the refection of the mirror. He was feeling her tits though the string dress, however she still had the tape on her tits. I asked Geoff if I could enter the bedroom , fucking stay there I will tell you when you can enter not until then.He openly fingered Carol while she was on her knees making her cum very loud and causing her tits to shake.He then told me to go the shop to get some more wine. When I returned Garol was resting next to geoff holding his cock and still in the string dress.Geoff then said that he was going to get Carol to ride him without any clothes on.I said to carol is that what you want to do, she replied yes now leave the room but keep the door open Carol was ordered off the bed and told to strip off her dress but leave the tape on her tits, then she sat astride his cock and started to slowly ride him.After Geoff been in control this is where Carol took the lead, she bent forward shaking her tits at him calling him a dirty old bastard and tell me how much you love my tits ,and how many times have you wanked off thinking of them when we was in the pub. She told him that she would be his white bitch and that he could stay the night if he wanted to and that I would sleep in the living room. I begged carol not to remove the tape has I didnt want him to see her big dark nipples, [ knowing that she would ] but she shocked me by shouting get in her now and remove it while am riding a real mans cock. I slowly get on the bed and cupped her heavy tis while she slowly rode him, kissing her neck and shoulders I removed the tape of each breast , geoff loved her large dark nipples and I fed them into his mouth while carol was moaning am coming. Geoff stayed the night and I was sent to the living room while he took her all night, the next day geoff left and Carol was in the shower, she told me that tonight she will have another suprise for me. When we got into to bed Carol was wearing a shirt of mine tide just under her braless tits we were talking about Geoff and how he had fucked her all night and that he loved her riding his cock and that he would be comimg around again soon.I asked her what her suprise for me was, with that she sat on my cock and started to ride me slowly telling me how Geoff could keep his hands or mouth off her tits and that he wanted me to let her go to his house for a weekend which I agreed if she told me the suprise, close your eyes she said, now open , when I opened my eyes I saw that her tits where covered in love bites 11 in total I came straight away and said let me know when you going to see him again.
