Back in the 70's when i was a lad of 18 i used to work for a small building firm attempting to learn the trade,most of the time i used to work with a big burly bearded bloke called Bill,he was alright, but i mainly just got to do labouring with him. Anyhow ill never forget the eyeopener i got one day on a job we where doing at this posh couples bungalow.The woman 'Francis' was really quite snooty and i don't know if you have ever seen the 'good life' on tv,that's exactly what she was like and even dressed and looked the same as Penelope Keith.Bill used to laugh about it,but she seemed quite a good sport,always bringing out cuppas and she seemed quite fond of Bill.One afternoon Bill couldn't wait to get rid of me it seemed,and not really needing telling twice i buggered off home as he said it'd be ok. But would you bloody believe it? I was half way home when i realised i had no bloody keys,i'd put them down in Francis's (Margo's) shed.Having retrieved my keys i noticed no sign of Bill and i thought 'Ah the crafty sod wanted to go home early himself'. I was about to leave when i heard noises inside the bungalow,i thought Margo had gone out and i suspected burglars,however as i peered through the window of the bedroom i saw something altogether different.Margo was in her bra and knickers and i could see she had a whopping great pair of tits on her and a big arse as well and big Bill was undressing her,as i watched i saw Bill take off his pants and out sprang the biggest thickest cock i've ever seen in my life,Margo shrieked in fright at the size of it, but Bill soon cajouled her into wanking it as he led her to the bed.The size of Margo's tits was phenomenal and Bill had a lot of fun wih them once he'd got her bra off,i was by now stroking my own cock through my jeans as he got her knickers off, he made her suck his cock too the dirty bastard and she looked like she loved it.There was a lot of snogging then Bill lifted her legs and pushed his big chopper right up her tight cunt,Margo really made a racket as he lifted her into different positions and fucked her every which way,it seems the toffee nosed lady loved big cocks,perhaps hubbies was too small.Bill even fucked her up the bum,i wasn't sure what he was up to at the time when he put vaseline all up her big arse,but i felt sorry for her as his giant member started going deeper and deeper up her shithole 'Oh Bill Bill' she kept saying in her posh voice,and he kept saying 'that's it Fran take it all the way' soon Bill was bellowing at the top of his voice and i'm sure the lucky sod was shooting his load up lady muck's arsehole. I never quite was able to look him in the eye again after that though. Eddie
