My partner impaled on cock

I happened all by chance one night in Brisbane, Kim and I were away for a couple of days break we had left on the Friday morning from Sydney and had booked into the Hilton in Brisbane for the 2 nights and were to return home Sunday night. We had spent the afternoon walking through department stores shopping and had gone back to the hotel for a rest, a glass of fiz and catch up on some reading. It was about 7pm and I suggested that we have a shower and go for a bite and a drink, Kim was in 2 minds as she just wanted to have a sip and read, so I said why don't you put on that sexy underwear you bought today and we go out for a couple of hours have dinner and a early night. The thought of her wearing that double D half cup which just covered her nipples excited me and she new it, so she agreed. Kim is a 5 foot girl in her 40's a little overweight which she carries ok with great tits, they are starting to show signs of gravitational force but still great tits and her nipples when aroused stand taught.
We showered and dressed casual, both in jeans and button shirt and her in a v neck top that showed enough cleavage for me to have a little peak when she bent forward. She likes to keep my interested, we had dinner and another bottle of fiz and were on our way back to the room and as we have to change lifts I suggested that we have a nightcap in the hotel bar which we did. We started chatting to two guys who were in Brisbane on business and were from interstate also, the night wore on and Kim bent forward enough times to reach for her drink and every time she did the guys who were sitting opposite had their eyes fixed on her tits as they swung in the looseness of the sexy red bra and loose top. It wasn't long before last drinks were called and we all caught the lift together as they were staying a couple of floors above us, in the lift they suggested that we have a drink in their room and I said no thanks as I was feeling a bit insecure with these two guys and Kim said that our room was first and that we had bought a couple of bottles of fiz while we were out shopping and they could have a drink in our room as it was the first stop. They agreed and we sat down at the coffee table while I went for the drinks, as we weren't expecting visitors there was a bit of a mess with clothes and shopping everywhere and on the table there was a pack of cards that we bought for a present as it had scenes of the outback on each card and we intended to send them overseas to some friends and the conversation had turned to that when I bought the glasses back with the bottle.
We have been swinging for a few years and we have had a threesome before but only with another woman and ever other time its always at a club or with couples, we fantasies about another guy as Kim loves the attention and loves her tits being sucked at the same time by two people, its just that I'm a little insecure about another guy, not to mention two. So needless to say that” why don't we play strip jack poker “came up and Kim loved the attention and had more than enough to drink and said why not. My cock was starting to twitch as I know here fantasy and she loves two guys and I said that I didn't know how to play poker so why don't we take one card each and the lowest card removes one piece of clothing and to add a little spice to the game the person with the highest card removes the clothing of their choice on the loser with shoes socks and jewelry not included, we all agreed and David and John were in their late forties with John being the elder and both nice style of guys .during the time of me getting drinks some how the guys were sitting on either side of Kim with me opposite , David shuffled the cards first and splayed them for us all to pick one , Kim drew the highest card with me the lowest and she was very smut as we stood up she undid the buttons on my shirt and put her hands inside and pushed the shirt back over my shoulders which held my arms she then started to work my nipples and gave them a pinch which made me jump and my nipples were hard which she made mention , the next to shuffle was John and Kim won again with David loosing and she stood and did the same to him only this time she sucked his nipples and I noticed his hand cupped under her tit as she sucked the other nipple and I knew she was hot and wet, it was Kim’s turn to shuffle with David winning and John loosing. David must have known of John's endowment as he walked around behind me and undid John’s jeans and dropped them to the floor where John kicked them to one side, he had boxers on and the cock that they were trying to hide was huge, I looked at it and was feeling very insecure and wanted to say ,ok lets go home ,but my heart was pumping and my breath was ragged knowing that I was going to see this weapon spread the woman I love and make her blow over it and fill her with hot cum. Kim loves a fat cock and I love to fuck her when she is full of hot cum. I looked across at Kim and she had not taken her eyes of it, as John sat back down he edged himself a little closer to Kim who was now in reach of his leg. The next few hands saw Kim down to her red panties with both her tits being sucked by both guys when she lost her bra and I could see the wet spot on her panties when she opened her legs to reach down to the coffee table to retrieve the cards David was down to his jocks and me down to mine also, we all had boners and Dave looked about the same size as me. The next hand saw Kim loose her panties and John had the pleasure of the job which he did so seductively and had a little rub over her clit which bought a moan from deep inside Kim’s chest. With Kim being naked and all of us with still at least one piece of clothing on, we said that if she loses the next hand the highest hand gives the order for the task she is to perform. She lost and David had the highest hand and he said that he wanted Kim to suck John’s cock. She looked over at me and I could see the sexual excitement in her eyes and I knew it was a one way street for her as she was going to get fucked by two guys and I knew that all I could do was watch and have my way with her once every one was spent. This excited me and scared me at the same time.
Kim by this time had been rubbing the inside of Johns leg and I'm sure every now and then giving the head of his weapon a little passing rub, John stood up and walked over and laid on his back on one side of the bed and Kim positioned herself on her knees and elbows on the other side and started to free this fuck stick from its cloth confines and as she got the boxers down and it raised its head out the top I’m sure I gasped , the veins that were down the side of it looked like pencils and its girth was that she could only just touch her finger to her thumb when she had hold of it, she started to lick the sides of it and ran her tongue down around his balls, and started to moan which broke my gaze as I was totally fixed on watching Kim sucking this cock I hadn't noticed Dave who was licking her cunt and sticking his tongue in her arse, I have never done that much before and she was loving it. Kim gives the best head and I've seen many a bloke fall victim to her tongue and when they blow she swallows it all and some times lets a little cum run out the corner of her mouth and it looks so hot, she was working on this cock like a woman possessed and I could hear the moans coming from deep down and I knew she was going to blow , David by this time had his cock out and was rubbing it up and down her wet slit and as he entered her she started to shutter and she made this slow hissing sound and blew to an orgasm of such intensity that she started to fall into John's lap, that didn't worry Dave as he put his hands under her belly and pulled her back up and started to give her a good hard fucking . I could feel the precum oozing out the end of my cock and sticking to my stud which was glistening in the light ,David was starting to make all the noises and I knew he wasn't far away and when he blew he slowly pulled out of her and cum was running down the inside of her legs, I reached down to feel the hot cum and I new it was not my turn, by this time Kim was starting to crawl up John's torso, my emotions were so mixed as I had no control yet I wanted to play stud master so I held John’s cock and started to give it a little rub and it was so hot, rigid and thick, I was so excited by this time knowing that Kim was going to be impaled on this weapon that I thought of giving it a quick suck just to taste the precum , instead I started to rub the head up and down her cum oozed slit and was making sure that it was well lubed for the task that it was about to perform as she pushed against the head, her pussy started to dilate and the head was forcing it way in and the moans started to come from deep inside as she started to ride this vein ridden monster and inch more of it into herself each time until she slipped down to his balls and would leave a residue of Dave’s and her cum on the shaft each time she rose off it. Dave by this time had his cock in Kim’s mouth and she was sucking and licking him clean and her continual moaning was starting to intensify and I knew that another orgasm was going to rattle her bones more than the first , John was increasing his tempo and Kim’s tits were bouncing and Dave and I had a nipple each which we were squeezing and the big fella blew and rocked the bed at the same time as her moans turned into deep throated short stroke sounds that reflected the intensity of each blow that was hitting her like a hammer and forcing into her own cunt and Kim was fucked , She gave John's cock a lick and a suck to get the last of his cum out and she laid back on the bed exhausted . The guys knew it was time to go and said good night and I slipped my cock straight in her sloppy and stretched hole which felt fantastic and lasted about three pumps and had a great orgasm, I wanted more but Kim was content and tired so she drifted off to sleep while I supported another erection which I gently stroked and rerun the night through my head.
The next night Kim said lets call into the bar on our way back to the room and said no because I knew what was lurking behind her innocent nightcap and I didn't feel like a night cap and she convinced me just to have one and when we walked in she had an instant smile on her face as she saw Dave and John over in the corner she walked over to their table while I ordered drinks from the bar, when I arrived at the table they were all standing with Kim in the middle with her arms around each of the guys waist and she said to me that she had invited John and Dave up for a night cap and their friend Vlad as coming too . Oh no I thought but deep down my cock was starting to twitch.
