It had been a long hot summer and I had just pased my 12th wedding anniversary when John,a friend for 15 years told me hed got a caravan on the coast and he and is present girl friend Diane where spending a week in it,would Dee,my wife and i like to join them on the final weekend for a party.John winked when he asked and hinted that if Diane was up for it partner swopping could well be in order!!

We joined them on the friday night and the party started well,due to the heat the girls were wearing very little,bra and panties to be exact,so john and I wore only G string briefs,it was at this point that i first felt a strange desire to get closer to John despite my wife and Diane showing off 36d breasts and very cheeky bums,the evening wore on and the girls got drunk and gave us a topless display and insisted john and i felt both sets of boobs to decide which girl was best when we couldend decide off came the panties so we could decide which girl had the closest shave.

John was making wood fast and i was happy with my hard on,so when the girls wanted to see who had the best hard on my G string was off in a flash,diane stroked it and made a purring noise and rubbed the bell end between her breasts,Dee fell on john a proceeded to suck his hard knob throught the fabric of his G string,I fealt a pang of jealosy,Diane stroked me gently till I came on her stomach,Dee sucked john till he came staining the his white G string dark grey,I moved to get diane on her back but she shook her head and said no sex,this.

Dianes refusal to go for sex swapping made John angry and started a row between them so diane refused to sleep with john that night,so he and i had to share a sleeping bag in the "spare room",an awning shelter hooked to the out side of the caravan,as we got ready for bed John peeled off his spunky G string,this was the first time Id ever seen him completley naked and was stirred by his firm athletic body and firm "fluffy" butt cheeks,itwas with excitment i slipped in beside him and felt his warm bodie against mine.We slept back to back at first,then john rolled "in his sleep" brushing his arm across my sholders and then cuddled up close,my penis stretched and lifted,I was aroused and didnt it didnt feel wrong!

I could feel his now hardening penis rubbing the small of my back, imade a comment about him being happy to see me,he chuckled and said he needed a wank but didnt do himself!!I was supprised to hear myself say "I dont mind trying to suck cock"!To my shock he said "Go for it"

With that I found my lips round a hard but smooth "rubbery" cock,all 7 inches.I let my tonge rub round the helmet,licking smoothly as if he was a spunky ice cream then sucked the tight helmet like a lolly pop,it didnt take long and I was warned a cum was rising as John started thrusting at my mouth.With this I held him against my lips and wanked him fast,the cum spurted across my lips hot at first,then it cooled to be a salty gell dripping down his softning cock and pooling on his dark pubic hair,his breathing calmed and he rubbed him self against me! We didnt know it but we where now hooked!!!
