I had gone into work on the Monday and before long a work colleague Gary from the Workshop came up to see me , to tell me Amy (my wife ) & I were invited to a party at his house on the coming Saturday, as he told me that he had been chatting with Rob & Tina ( who are also work colleagues and have become regular fuck buddies over the past couple or so months ) who were both coming along. I did chat with Rob later in the day and he told me Gary had told him it would benefit him & Tina if he came along and asked him to get Amy & myself to come along as well, I knew what that meant and said to Rob he obviously wants to fuck Amy & Tina again like he did when he bowled in your place the other week back and no doubt the other 2 lads Ryan & Andy will be there to have their turn as well. As Rob said well I felt I couldn't say no really as he showed me some pics on his phone he had taken that day , Rob said I know he has shown some of the pics to the staff here but those were fairly tame to the ones he has on his phone so was difficult to refuse and you know he has a Hot tub as well, I told him I didn't know that . As the week went on Rob kept popping up to chat with me telling me he wants Tina & Amy dressed in some skimpy bikinis and looking good when they walk in dressed , I just said well they always do ! , Rob added I have heard Gary telling a few of the others in the workshop to come along and see these 2 horny bitches and told them that Dave's ( Me that is ) Wife Amy is well fit has a great body and tits an proper horny and can't get enough cock as I expect you can see from the pics he had shown them all. I had told Amy about the party at Gary's and that he had a Hot tub as well, she said ok sounds like could be fun but Rob & I hadn't mentioned that there might be a bigger gathering of people there as well, I think she thought it might be just Rob, Tina, Gary , Andy and Ryan, as luckily she doesn't work in our company and Rob said we don't want to scare her off. I had other thoughts though that knowing my Wife she might just love being the centre of attention along with Tina and any other women who might be there if there were any others , as Tina was aware that it would be a larger gathering , but did come up to me to say I feel safe with you there to me on the Friday at work over our lunch . That Saturday afternoon I watched Amy go off to the bathroom and appear some time later in her robe ,to stand in front of me and open her robe like a male flasher to show me her sweet smelling body her pussy freshly shaven and moisturised with a hint of her juices on her pussy lips , as she asked how do I look , I told her she was gorgeous and she smelled even better as I ran a finger between her pussy lips to taste those juices , to tell her she even tasted lovely as well. I watched Amy dry an curl her hair as she pulled on a bikini I hadn't seen before , she saw me looking and said it was going to be for our holiday next year but thought I would wear it tonight , I told her I don't know what you paid for it but you should get your money back as there is hardly any material covering you, not that I minded as she looked fabulous in it and was hoping to see her tonight and on our holidays wearing it. Amy finished dressing while I showered and dressed and I noticed she had worn some heels with hold ups under her tie belted mini dress. We headed off to pick Rob & Tina up from their house , Amy knocked on their door as Tina came out looking lovely as well, I think the girls must have consulted each other on what to wear and she got in the front leaned over to kiss me and squeezed my cock through my trousers as Rob & Amy got in the back seat , I saw Rob's hand already making it's way up Amy's dress as I drove away. We got to Gary's house and at the door , Gary was there to greet us, well Tina & Amy as we followed them down the hall , seeing Gary with his hands on both their bum's as they walked ahead of us , he led them outside to his garden where a table was piled up with drinks and he had soon opened a bottle of bubbly for the girls to drink. Rob & I had stopped in the doorway to pick up a can of beer each , by the time we looked up again Tina & Amy had been descended on by the other guys there who had been chatting in a group in the corner , Rob said to me God they are like vultures , but don't the girls look great tonight to me , I nodded , as he told me I see all the lads from the workshop are here tonight and a couple from your office , as I got a tap on my shoulder and turned to see Ann who works in the office with me , I gave her a kiss on the cheek as I said didn't know you were coming along and offered to get her a drink. Then Ann told us thought she would come as she had seen the photos that had gone around at work and told us she liked the look of Amy & Tina and hoped maybe she might get to enjoy some fun with them as well , I smiled at Rob as we all knew she liked girls but never thought she would have the nerve to come along with so many Men here. We chatted as Gary came over to turn up the music and saw Amy & Tina being pulled into the middle of the patio to dance with a couple of the lads , as another lad asked Ann to dance as well , Gary chatted with us to say the girls scrub up well , even Ann looks nice tonight. The lads all took turns dancing with the girls , there was a rush to dance with them when a slow number came on and I could see Amy's neck flush red which I knew was a sign she was feeling horny, on the next slow one they came over to grab us both , as Rob held Amy as Tina & I danced , Tina whispered to me I think Amy is going to get well fucked tonight the lads cant get enough of her you should have heard them all at the start of the evening , I told her I think you will get your fair share as well and I hope I get a chance as well , she grinned at me saying you always will , Dave ! Then as the music changed both girls were whisked away to dance with Ryan and Andy who had emerged from the others , when there was a countdown from the rest of the lads from 10 and as they got to 1, Andy who was dancing with Amy and Ryan who was with Tina suddenly pulled off their belts holding their dresses together , so everybody could see what they had on underneath , as 2 of the lads moved behind the girls to pull their dresses down and off of their arms . That was when we heard a gasp amongst the lads , then the clicks of a ocean of flashes from cameraphones and a big smile on Ann's face as they all saw Amy & Tina stood there both in hold ups and their bikinis, we saw the smile on the girls faces at the lad's reaction to seeing them dressed like that, you could hear the voices being raised as they all spoke at once at seeing the girls , even Gary came across to us both to say Fuck ! they look ravishing tonight , these lads want to fuck these girls tonight after seeing those pics I took before at your place Rob ! Then Gary announced its Hot tub time for anyone who wants to go in there, Rob & I looked on to see Andy leading Amy over to the tub along with Ryan & Tina by the time they had got the few yards to the tub both lads were naked then we all watched as Tina & Amy took their heels and hold ups off and to whistles as both girls climbed in the tub, while some of the other lads began to strip off as well now and headed over . Then Gary announced there are condoms around the place and some in a waterproof container in the tub feel free to use and enjoy yourselves boy's an girl's , we watched Amy's & Tina's bikini tops being thrown in the air as Andy threw Ryan a condom but I was sure they were just going thru the motions in front of every body else there and don't think they made there way onto their cocks as they fucked the girl's bareback before . As all eyes were now diverted to seeing Amy and Tina stepping out of there bikini bottoms now as they were thrown in the air as well by the girl's , who were swiftly grabbed by Andy & Ryan and pulled down to straddle their legs and sit on their hard cocks . Then as all faces looked on at the tub and the fucking going on with both lads kissing the girls and then sucking on their boobs an nipples, right in front of us we saw Ann stripping off to reveal a firm pair of boobs as well as a shaven pussy with a heart tattoo above, also a lovely bum as she flicked her dark hair back to head over to the tub as she got in one of the lads Nathan followed her in sat next to her and they were soon kissing and he was sucking on her boobs as well. We looked on to see Gary had stripped now making his way to the tub a couple of lads were sneaking photos on their phones of the activities , both Ryan & Andy had filled Amy & Tina with their cum now as it seemed Gary had timed his arrival perfectly and told everyone that both girls were going to suck his cock before he took turns fucking them as they bent over holding the side of the tub , he had the attention of everybody as he stood in the middle of the tub and both Amy & Tina worshipped his cock licking and sucking it as he wanted . Then Gary called time and said its my party so you can all watch as I fuck these 2 sluts with my bare cock and fill them with my cum , but the rest of you must wear condoms , Right Girl's !!! Tina & Amy said Yes ! Gary !!! , Rob & I had moved closer now to hear a couple of the lads saying fat chance if he gets to fuck them bareback so will we , how will he know , when the lads realised we were next to them they looked on a bit sheepish saying you alright, Rob, Dave ! Yes , fine we both said ! All eyes were on Gary now stood behind the 2 lovely bums of Amy & Tina , taking turns to slide his cock in and out of their already cum soaked pussy , as we had noticed Andy & Ryan laughing at Gary's words earlier so we knew they had done the deed , I had to admire Gary's stamina as he fucked them both, I said to Rob think I would have cum in them by now . Rob just nodded as I thought Rob also has a case of being able to fuck for quite some time as remembered watching him in the past with Amy in the their tub and on their sofa , I think that was part of Rob's attraction to Amy , that he could fuck her for ages making her cum many times before unloading inside her warm pussy. Even Gary could not hold back for long and we all watched as he announced he was filling Tina's pussy as he pulled out splashing some cum on Amy's bum before he pressed his cock inside her hot pussy as well , the lads who had been taking pics on their phones had filmed Gary cumming in both girl's and congratulated themselves on the photos , as Gary moved away he was quickly replaced by the 2 lads Leigh & Alun who worked with Rob and had said about not using condoms earlier , They hadn't given the girl's time to move as they slipped their cocks inside them both , then as if feeling eyes on them they both looked over at Rob & myself to see our faces , but in a split second they were fucking both our girl's in front of us , Leigh reached under to feel and rub on Amy's boobs while Alun followed tweaking an pulling on Tina's firm nipples making her cry out she was cumming again. I enjoyed seeing Tina cum like that as I loved to see her cum when I did that to her , where as I think Rob was always a bit jealous of whoever was making Amy cum on their cock as he looked on, I must admit I have always enjoyed seeing another man's cock filling my Wife's pussy I look on loving the idea that a guy wants to fill my Amy with all his potent sperm and as he does he owns her body for a short while and love that she has the power to make a limp cock into a throbbing monster that wants to fuck the life out of her. I think that is why I love to see her on Rob's big cock as he so enjoys her body to use for his and her pleasure, as due to his size he can give her something I cannot match and I know she loves the feeling of his big cock , even though she tells me she still wants and loves me. I will carry on with this in Part 2 as the night lasted a lot longer, hope you have enjoyed so far ?
