After a argument my wife went to her office party at a hotel in town without me as she left home she was looking so very hot! little black dress, black stockings and suspenders, tiny thonge and killer heals. Sometime in the early hours she rang me to say a friend would be coming back with her and staying over at ours as they had drank to much and could not drive,so it was arranged and they arrived in a taxi however what she had not mentioned and i hadn't realised until they entered the lounge was her friend was a bloke she had met at the hotel. He thanked me for being so kind in letting him stay over. My wife put on some music we had drinks and chatted then she started dancing first with me then with Mark, her dress kept flying up giving glimpses of her stocking top and the flesh above,I noticed he couldn't take his eyes off her she started flirting with me and fondling my penis which by now was erect and in full view of him she started to wank me and i soon shot my hot load. This was her plan to make me cum first as it takes time for me to recover after cumming, she glanced at me with a smile and then in front of me turned her attention to this man who by now was also sporting a erection through his trousers, they danced very slowly hands allover each other then she beckoned me and wispered for me to unzip her dress and it slipped to the floor revealing her sexy black stockings and suspenders his eyes nearly popped out of his head. She then undid his trousers and he was down to just his boxers in a flash she knelt and slid them down and out sprung his large erect cock, about 2 inches longer than mine leaking pre-cum she took hold of his cock and started to wank it, then while looking at me took it in her mouth and started slurping and sucking hard, she looked so sexy with his cock in her mouth until he could last no longer and shot several heavy spurts of hot spunk into my wifes mouth and she sucked and lapped every drop up,I was mesmerised as she has always been reluctant to swallow my cum. She came over to me and kissed me hard forcing some of his cum into my mouth which took me by surprise (warm and salty) she laughed and said hope your enjoying the night, because your going to see your wife get a proper fucking from a decent size cock. We cleaned ouselves up and then retired to the bedroom were she told me to sit and watch and learn he then fucked her hard from behind until she gave several loud moans and orgasmed then he came and filled her pussy with his hot semen, as he laid back exhuasted i took his place and slid my cock into her slimey pussy and very soon added my own hot load, she then surprised me by putting my head between her thighs and i licked the mixture of his, mine and her juices from her engourged pussy. During the rest of the night i watched as he fucked her twice more his spunk was everywere and in the morning before he left she gave him another fantastic blow job she was loving it and later said it was fantastic being shagged by a larger cock and asked me had i enjoyed watching her being well and truly satisfied by another guy?. I had to admit it was a turn on after the first pangs off jealousy had worn off when she first sucked his hard cock,i was forced to accept i could not satisfy her like he had. She now wants to repeat this again !!!! saying it will keep our marriage fresh and happy and her feeling sexy and fullfilled.
