Last year my wife Shauna and I move home and bought an apartment in North London. We soon became friends with the couple living below us, Linroy and Debbie. Like us they were both in their forties , previously divorced and have no kids. Linroy is a 6 ft Jamacian while Debbie is Scottish with a petit size 10 figure , short blond hair and big boobs. My wife Shona and I are Irish . Shona is a busty size 14 with shoulder length red hair while I am 5.ft 10 going grey. Debbie and Shona became best friends and frequently visited each others homes. Linroy and I would often grab a few beers and watch sport upstairs while the girls would have a bottle or two of wine togather at Debbie's place. Linroy's father Noel would often visit . He is divorced and lives near bye. He is a randy old git and never misses an opportunity to pass a saucy comment or pinch Debbie or Shauna's bottom. Linroy told me his dad is known to be hung like a donkey and is pussy mad which is why Linroy's mum divorced him, especially when she found out he was shagging her sister. We noticed Debbie and Shauna loved to tease him by wearing low cut tops and short skirts when ever he was due to visit. And they would deliberately bend down near him to give him a flash of their boobs or knickers knowing this resulted in him get a hugh bulge in his trousers. It was soon going to be Noel's 70 th Birthday and Linroy wanted to throw a surprise birthday party for him at his place . Debbie and Shauna agreed to do the food for the party. Linroy invited about 10 of Noel's mates and arranged a striipagram . Debbie wasn't to happy about the striipagram at first but agreed Norl would love it so she finally agreed. On the night of the party all was arranged when the striipagram cancelled due to illness . The agency couldn't get s replacement in time and Linroy was very disappointed . Jokingly he said to Debbie you will have to do it. The girls had been on the wine all evening while preparing the food and were quite merry but Debbie said no way ! Shauna and I were calling her chicken when she said ok but only if Shauna joins me and we only strip to our undies? Shauna was forced by us all to reluctantly agree. So by 8pm the guests had arrive and the girls after more wine for Dutch courage were dressed and waiting in the bedroom for Noel to arrive . Noel's mates were a mixed bunch of West Indian and english guys all in their sixties or early seventies. The birthday boy arrived at about 8.20 pm expecting to be comming for a birthday dinner and was very surprised to see all his mates there. He asked where was Debbie & Shauna but we said they were in the kitchen preparing food . After about half an hour Linry put on some strip music and out came the girls dressed in St Trinian style white blouses , short skirts , stockings and high heels . As they started to dance and slowly undo their blouses all the guys clapped and cheered especially Noel. Debbie and Shauna were clearly enjoying the attention especially after having several bottles of wine between them . Soon their skirts were off to the sound of loud woolf whistle's Linroy and I expected them to stop at this point but they continued to dance I just in their underwear and heels . The other guys were shouting for them to get them off. And Debbie teased them by loosing her bra and Shauns followed suit. Both women werr simply holding their bra's in front of their breasts giving the guys a glimpse . The guys were loving it and begged them to to take their bras off and Linroy and I joined in the encouragement . Debbie suddenly grabbed Shauna's bra and her own and flung them to the guys. Noel was loving it as both women danced around him topless. And all eyes were on the two womens large boobs which were bouncing as they danced and both women were clearly loving the guys reaction. They started to undress Noel and he to was only in his boxers. He had a hugh bulge in his pants as he danced with the girls and he was grinning like a Cheshire Cat as they teased him about it. Debbie reached over and yanked down Noel's boxers and this huge black cock sprung to life which looked to be about 10 inches . The girls were clearly surprised by Noel's dick as them stopped and stared and Shona said bloody hell look at the size of that ! Noel just laughted but danced around the girls and when he got behind them reached over and grabbed each by their knickers and ripped them off. Leaving them with on their high heels and stockings on. Debbie and Shauns screamed and covered their now bare pussies with their hands but Noel was prodding them with his erect dick as he danced around them. Debbie grabbed him by the dick and theire were chants of Blowjob, . Both women pushed Noel down on his back on the carpet then bent down and pretended to lick his dick ! But Noel wasn't going to miss an opportunity and pulled their heads towards his cock to loud cheers by the other guys . Debbie and Shauna didn't object , instead they started both to lick his cock ! As they bent down it give the other guys a perfect view of their moist pussies and soon both women were on their knees taking it in turn to take his cock in their mouth . Some of the guys shouted to sit on his dick and Debbie obliged by slowly impaling her self of his big black cock. She give a loud moan as it slid into her pussy and she rode him cowgirl style while Shona sat on his face as he eat her pussy.. The other guys cheered wildly as a very drunk Debbie put on a show by moving rapidly up and down on Noel's 10 cock. as her breasts bounced . Soon Debbie had an very loud organism and Shauna and her changed position . She didn't disappoint her audience either as she bucked wildly. She let out a scream as clearly Noel filled her as she came. Both women got a round of applause as the birthday boy staggered to his feet. They went to their beds to sleep of the wine while we continued drinking. Next day they were a bit sheepish but that night we ended up swapping partners and now on occasions Noel and a girlfriend join us for a fuck party.
