Allan our next door neighbour was approaching his 50th birthday He had been my sucking mate for some years and my wife knew but was happy as long as I kept her well fucked as well She thought about it but said how could we let him without him knowing that she knew. After some thought and conversation we came up with an idea and this is what happened. On his birthday I invited him round and the three of us had a couple of drinks. Then I took my wife upstairs where she stripped then lay on the bed, I tied her ankles and wrists so she was spread eagled and put a blindfold on her, closed the curtain so the room was very dark then finally before leaving I went down on her and gave her oral bringing her to a nice climax. She was nice and wet as I knew Allan was well endowed with a good 7 inches and nice and thick against my 5 and a half but fairly solid. I went down, Allan was sitting expecting us to have a sucking session and was already stripped naked. I told him his dream had come and to follow me. In the bedroom my wife's outline was just visible in the darkened room and he just couldn't believe his eyes. I whispered to him that she didn't know it was going to be him but he could do anything he wished. Without a pause he dropped down and began to suck and lick between her legs. I stripped as he did and then fondled his prick and balls. He was already fully erect My wife had a massive orgasm and as she did Allan eased up and lay on her his prick entered her fully without any effort. He went wild thrusting hard and deep every stroke and it only took about 30 seconds before with a final thrust he shot his load into her and lay flat still on top of her gasping as she was having had another massive orgasm she told me later. As he slackened off he rolled off her and lay beside her, his limp prick wet with her juices and his spunk. I then got on the bed and took over entering my wife's wet sticky cunt, an unbelievably feeling as I fucked her. I let her know it was me and she said she knew as he had felt so big. I brought her to a final climax then Allan went downstairs leaving me to untie her. Downstairs when I went down Allan was sitting still naked on the settee and I couldn't resist going don on my knees and sucking him even though he was slack The taste of her and him was out of this world and I soon was erect again so Allan took over and sucked me to completion. He had just finished when my wife walked in fully dressed. The outcome is that now she wants regular session with Allan and we have a threesome on an average once a week. Both her and my sex life have improved dramatically and Allan is a much happier guy
