I make no excuses for the length of this “story”...it is my fantasy after all.... LoL, I hope you enjoy reading it as much as I enjoyed writing it.... :o) We turn up at the house, it is a large house with large gardens and a long drive, it looks like it must have seven or eight bedrooms.....very impressive, looks like it should be a good night if the house is anything to go by. We meet the hosts, a very nice couple who invite us in and make us feel very welcome...they offer to take our coats and let us know that they are putting them all in one of the spare bedrooms...funny all that space and they still put the coats on the bed just like the rest of us.... The house is packed, lots of couples as well as many single girls and guys. It’s a great party, we drink a little (not me obviously) we dance a lot and we mingle and have a great time. My friends and my partner are enjoying the hospitality...drink is flowing freely and I can see that I’ll be looking after three tipsy party goers again later lol Much later in the evening my friends are curled up in a chair, they have reached their limit and are just zoning out...my gf is just dancing, she loves to dance and is getting more than a few admiring stares from some of the younger single guys. As she dances around her short little black dress hugs her curves nicely...it shows off her great legs and cleavage....no bra again, and a lovely little G-string. Time goes on and more dancing, more drinking....we dance and she also dances with a few of the other guys, she likes the attention...to be honest, who wouldn't love the attention...it’s a lovely compliment. Soon though the inevitable drink takes its toll on my gf as well and she says it’s time to leave, she says she will go and find the coats...I’m not sure that's a good idea but she insists...and I go and look for our friends. Luckily they are still where I left them some time ago and chatting drunken babble to the other guests. After a while I wonder where my gf has gotten to and go and look for her....finally I find her curled up a sleep amongst the coats in the spare room....so I decide to leave her to have a little nap...she is always better after a nap. I return to the party and enjoy another Coke...living life to the max....lol ...our friends are still in the same place, they aren't going anywhere anytime soon so no need to get them moving right now. I leave it about half an hour and my gf hasn't wandered back yet so I go to recover her from the coat stack...as I get near the room the door is slightly ajar and I can see a couple of the young guys from the dancing earlier also in the room....must be looking for their own coats to go I imagine....crap, I hope they don't wake her... lol As I get closer I can see that they have discovered my very drunken, very sleepy gf in the coats and are gently trying to wake her, that's sweet but I know that isn't going to work with her having drunk that much. As they gently try to rouse her she rolls onto her side and pulls her knees up and curls into the ball position she mostly likes to sleep in, in that dress though it just almost eases her lovely tits out of the top of her dress...but more importantly shows off her entire ass and G-string now pulled very tightly across her bottom and pussy....the guys can’t help but notice. I know I should go in and intervene...but my feet do not seem to be answering and I am rooted to the spot and watch why one of them gently stokes her exposed ass...her body quivers a little, not sure whether it is the gentle stroking or some dream she is having...the other guy moves closer and starts to stroke her tits gently through the thin material of her dress....she moans gently in her sleep and pulls her knees up tighter which pulls the G-string up between the lips of her pussy....again not unnoticed by the guys.... One of the guys has slipped his hand into the top of her dress and is gentle stroking her tits and tweaking her nipples...even through her drunken haze, and although she doesn’t appear to be coming to very much, I can see she is getting turned on....so can the guys so they step up the pace...one is kneading her tits and playing with her nipples...the other has moved his hand around between her thighs and is stroking her pussy though the very thin material of her g-string.....which I can now see is very wet.....he increases the pace and she wiggles and gently moans in pleasure....she appears very turned on... I stand there in a daze, it is such a horny sight, I should do something....but all I do is stand and watch.... Whilst in that daze I almost missed that the guy has now slipped his fingers past my gfs g-string and into her very wet pussy...and is now gently wanking her off with two fingers in deep and his thumb pressed hard against her clit...her breath is coming in shorter shallow gasps as she reaches the point of no return...she still seems to be in a dream like alcohol filled state but she is just about to orgasm.... As the pleasure slides through her body she holds onto her knees tightly and arches her neck back as she opens her mouth and lets a quiet low pleasured moan as her orgasm take complete hold of her body....I think I hear someone coming down the corridor past the other bedrooms so quickly check...thankfully no one... I return to the door to find both guys have now removed their trousers and have their hard cocks out....again I know I should intervene, I know I should step in but I am mesmerised by the incredible horny sight of my gf being unknowingly pleasured by two horny young guys..... The guy who had been playing with her boobs had moved in closer and was offering up the end of his cock to my gfs slightly open lips...his cock is a fair size, similar to mine and currently leaking a little precum...even in her drunken state her lips know when a cock is being offered up and her tongue licks the precum...and then her lips close around the end of his swollen cock as he starts to gently fuck her mouth, she automatically latches on to his cock and starts to suck him urgently. I now notice the other guy, so caught up had I been in my gf sucking cock....his cock is far from average, at least 9 inches and very thick...I doubt I could get my fingers two thirds around it...he manoeuvres around and starts to rub the end of his cock against her pussy through the material of her g-string...she moans in pleasure and angles her bottom up slightly to allow more access...he pulls her g-string to one side and slides his cock into her very wet pussy...it is so long and so wide I cannot see how it could fit in my gfs pussy...but in and in it goes, right the way to the hilt...as he reaches the point of his whole cock being sunk in my gfs pussy she lets out a small trembling sigh...and returns to the almost automatic task of sucking the other guy off.... The guy who is fucking her grabs her upper hip and thigh and starts to slide his large cock in and out in a gentle but determined motion...the sight is unbelievable, I could never have imagined it would fit....but in and out it was sliding without seemingly any trouble at all.... Now it was the turn of the guy who cock was in my gfs mouth to start with the deep shallow breaths and I knew he was very close to emptying into my gfs throat...she also seemed on the verge of another orgasm if my guess was right...one, two, three more strokes and I could see the guy stiffen and pull my gfs head onto his cock as he shoots his load into her mouth....she clamps on tight and swallows down every drop....almost as that happens she also twitches as another orgasm flows through her whole body.....but the guy who is pushing that huge cock into her doesn’t let her rest and ups his pace and keeps her on the edge of that orgasm with those long deep strokes....until at last he also can’t hold back any longer and empties his load deep deep in her pussy.... After they have finished they wipe their cocks off, they return my gfs g-string and dress to their normal positions and hunt out there coats and get ready to leave....time for me to make a quick exit back to the party..... When I get back not much seems to have changed, my friends are still in the same place, although she is now asleep on the chair with mate. No one seems to have noticed or cared about the elapsed time and I just pick up my drink and pretend to listen to the conversation. A few minutes later the two young guys appear with their coats and start to say their goodbyes....as they pass I wish them a safe journey and shake their hands....the hands that a few moments ago were pleasuring my gf...I almost couldn’t suppress the quiver of excitement...I know they recognise me and for a second look a little concerned that I might know something...but I smile and say what a lovely party it has been, and ask them if they had enjoyed it too....both smile back with the look of “he knows nothing” on their faces and say that they had had a great time... (Indeed you have I smile to myself..). After a while my gf appears with the coats....she looks a bit dishevelled and still very tipsy...she apologises that she took a little while, I say “it’s not a problem, I came to find you”....is that a very sheepish look I see, but continue with “but you were having a little nap on the bed and I didn’t have the heart to wake you so left you there for a little while....”.... We collect our friends and I drop them home first and then return to ours....I am still very turned on and cuddle up to my gf and she can clearly feel my cock pressing against her...I know she must be tired but I need some release after watching those young guys cum in her....she turns around and strokes my cock and then slides down and starts to suck me off just like she had done the young lad earlier....the memories come flooding back and I know it will not be long before I cum...I reach around to stroke he pussy like I always do when she sucks my cock...at first she seems a little reluctant and keeps her legs closed but I am insistent and need to feel her...she relaxes and I rub her gently and slip my fingers into her pussy....it is still very wet and sticky and the other memories return of that large cock sliding into her and filling her full of cum...which my fingers are probably soaked in now....instantly I shoot my load which has been building all that evening, and for the second time that evening I see my gf swallow every last drop..... After my orgasm subsides a turn to my gf and say “your turn...” but she says she is too tied and still quite drunk so would rather have a cuddle....so we curl up together a drift off to blissful sleep....
