My wife and I were invited to a Barbeque/pool party this past summer. We had been working so hard the previous weeks leading to the party, that we said that we would ask the host, Kim and Mark, if they would put us up for the night (so we could drink and not have to drive). They said, "Sure!!".
The party started around 5 PM, with many couples coming and going over the course of the evening. By 10 PM, everyone was gone except, our hosts, us , another couple (Dean and Dale) and Sherry, a busty redhead, who had recently dumped her boyfriend.
Obvously by 10PM, we were all a little toasted, and feeling real good. We were all chiding Sherry that she must be horny not having a boyfriend...to which she responded, "yeah!!...no kidding!!"...eventually the talk got raunchier and raunchier, and Sherry decided it was time to skinny dip...so we all took off our bathing suits and jumped into the pool. My wife has a great body, and at 150 lbs, all the weight is well placed and contributes to her sex appeal. Though she has smallish tits, they are perky and well shaped. Kim had a tinier body, but she was kind of shy about showing it off. Sherry is a plus-sized girls who flaunts herself and is quite an exhibitionist. Dale is tall and is a little chubby, but makes up for it by being incerdible pretty and vivacious. Mark and Dean have average bodies, with average cocks, my self included. during all the naughty talk, Mark asked Sherry if she has been diddling herself too much, Sherry responded that she masturbates quite a bit, and that she has a little help from a vibrator called, "The Flicker". she also said that she liked to lick her own nipples (she has nice big tits). My wife, who has small tits, asked for a demonstration. Sherry showed us, and as she was performing this erotic scene, my wife grabbed my cock under the water and I heard her moaning at the view. Kim and Dale tried to do the same with their breasts, laughing that they were not able.

Mark asked Kim if she would like it if he did it for her,...she gladly accepted and maon as her took one nipple, and the the other in his mouth. By this time, we were all groping each other without embarrassment. Sherry responded by saying, " this is too much...I' sooooo fucking horny!!!....With this she proceeded to sit on the pol deck and started diddling her clit right in front of us. My wife suggested that I sit on the edge of the pool so that she could suck my cock. she didn't have to ask twice!...Mark and Kim were in an embrace and she was obviously playing with his cock and he was sucking her tits. Dean joined me on the deck and got a great blowjob from Dale. It was then I noticed that Dean had a much bigger cock than I thought. Sherry moved closer to them and stared in awe as Dale bobbed her head up and down on his shaft. With some frustration, Sherry yelled, " I could use some of that cock!" Dale stopped sucking and said, "Well get over her girl and show me how it's done" Sherry is a big girl and when she got on her knees to suck Dean's prick, I had a great view of her tits and her ass. I commented to my wife that I could use a little of her myself. My wife Robbi said, " let's both do her". We got out of the water and Robbi proceeded to lie down and suck her tits. I went behind Sherry and spread her big ass cheeks and revealed her pink pussy and her asshole. Hmmmm it sure lloked delicious. I layed my tongue on her pussy hole and gently placed my thumb on her asshole....I got a greatful "Aw...YEAH" for Sherry and I continued the assault on her wet pussy. I finger-fucked her pussy for a bit and every so often liked her clit. Glacing over at Sherry doing her sucking, I noticed that Dale was also feasting on her husband's cock at the same time (lucky guy!!) Dean groaned, "I'm gonna CUM!!!!!" and both girls got a fountain of cum obver their hands and faces. Two seconds later Sherry's bodyshook and she came with a squeal. Robbi continued sucking her tits and I noticed that she was rubbing her own clit too. I reached over and massaged Robbi's clit for a bit and decided to take a chance and jerk off with one hand, while finger-fucking Sherry with the other. I stopped pumping myself because I was so close to cumming. Sherry decided to remove herself from the action because her clit wa too sensitive and she wanting to watch the action for a bit. I then told Robbi to get on all fours and proceeded to fuck her from behind. I pumped her about 4 or 5 strokes and had to stop. I did't want to cum right away. Robbi begged me to lick her pussy and I responded by maiking her stand up in front of me and told her to open heg legs so I could have tongue access to her clit. She was dripping wet and tasted sweet. Out of nowhere, Kim appeared behind Robbi and started playing with my wife's tits...saying how hard her nipples were ...Robbi closed her eyes and was loving the attention. Mark in the meantime was urging me to lick Robbi really good. He was watching the whole scene and playing with his cock. Sherry started to fiddle with her clit again, and asked if Mark wanted to get blown. Mark looked at Kim for premission and Kim said, " I think she needs cock...give it to her". Sherry squealed with delite and grabbed his rock-hard erection and started pumping him and ogling his prick with lust. She must have been quite good because within seconds he told her to slow down or else he was going to jizz. Kim asked Sherry to let her finish him off, so Mark moved to Kim and Kim said, " you are going to come in my mouth big-guy." Sherry stood behind Mark holding his cock and guiding to Kim's mouth. Jerking him off while his cock was in Kim's mouth, Sherry said, " yeah....c'mon...cum in her mouth, cum in her mouth..." Mark erupted and filled Kim mouth with hot sperm. Obvious Kim didn't like to swallow, so she spit the jizz out onto the deck and got some pool water to rince her mouth, leaving Mark panting and saying, " fuckkkk...man..."....Sherry grabbed his cock and licked him clean. By this time Robbi was cumming hard and I was ready to blow. Robbi turn around and gave me a hand job, spraying my cum all over her tits...Sherry said, " Fuck man,....can you cum any more?"....my jizz was plentiful and covered my wifes chest pretty good....I responded to Sherry, " well, if you let me fuck you, I will cum some more"...She put her hands on a table, lifted one leg on a chair and said, " come and get it!" I was still hard, and entered her with ease, as she was dripping. My wife stood next to me and played with my balls while I fucked Sherry. She had a big ass, but well rounded and a pleasure to look at. Robbi, from time to time would grab my shaft and take it out of Sherry's pussy and suck on it, then re-insert it in her cunt. Within five minute I came again, tho not nearly as much as the first spray. Robbi pulled me out as I came and jerked me off onto Sherry's ass.

That was pretty much the end of our evening, though we did have a foursome in the morning with our hosts!
