This story is completely fictional, all character names are fictional. I prefer to write a story that is sensual with foreplay and pleasure for all parties, if you are looking for hardcore sex then these may not be the stories for you (pornhub may have what you are looking for).
Prelude
John and Brittany had booked a 5 night trip to a lifestyle resort to get away and enjoy some time at the beach and meet some new friends. This was adult time so they were leaving Brittany's two daughters at home to look after the house.
Brittany arrived home from work, "Hey John, are you home?" she called out.
"I'm in the kitchen babe" he replied.
"Hey, I've got some unfortunate news for our trip, work has asked me to travel interstate to help with this new site setup. I'm really disappointed that I won't be able to go away as planned. I can't really say no or change work dates." Brittany told John.
"Oh that's a shame...I was really looking forward to that week away. We can change it to another week" said John.
"I was too, but you don't have to change, we can go another time. You could ask one of the girls if they wanted to go." Brittany suggested.
"Really, you're ok with that?" John asked.
"Of course, I'm sure one of them would love to go. Besides I know they have been interested in going since we told them about it. Why don't we ask them at dinner?"
"Ok, but only if you are sure you don't mind missing out and that I take one of them. If they can't go, then we can just reschedule." said John.
"When is dinner, by the way? I'm starving." Brittany exclaims.
"I will get the BBQ fired up and start cooking and it should be ready by the time the girls get home from work." John replies.
"Great babe, I'll go get out of these clothes and take a quick dip in the pool." Brittany says.
Brittany wanders off to their bedroom to get out of her work clothes. As she goes through her drawer of swimsuits she can't decide which one to wear, as the girls are not home she goes back down to the kitchen sans clothes. The girls won't be home for another hour, she thinks she has time for a quick skinny dip.
As Brittany goes past the kitchen, John is not to be seen so she assumes he must already be out on the patio cooking. It's not unusual when the girls are not around for them to both swim and sunbath naked.
She slides the door open and heads outside, John is cleaning the BBQ and looks around at the sound. As soon as he sees Brittany naked its gets him aroused. "Honey thats daring when you know the girls could be home anytime."
"I can see that's not what he is thinking," as she looks down at the growing tent in his shorts. "Wanna come join me for a quick swim, the cooking can wait. Besides I think I'm hungry for something else now."
Brittany points at John, "You have to take those off first though!" Meaning the singlet and shorts he is wearing.
"What if the girls arrive home?"
"I'm sure it's nothing they haven't already seen and besides you will be in the pool and they won't be home for what, another 45 minutes at least? Just get those clothes off and come join me."
John strips off the singlet and shorts and leaves them on the pool chair and walks over to Brittany. His cock fully erect now, "Damn you are beautiful," as he pulls her close and kisses her on the lips. Brittany's breasts pushing against his chest, her nipples harden from his touch.
John grabs her cute round butt and pulls her closer to grind his cock against her. Brittany moans as they passionately kiss. "Ok lets go for a swim," John says as he pulls out of the kiss.
Brittany now has other ideas and leans in to keep the kissing going. Nibbling on his ear she whispers "I want to fuck you here, you got me all turned on and I don't want to swim now."
His cock twitches at the thought, Brittany parts her legs and lifts herself up to grab his cock between her legs. John's cock is rubbing along her wet slit and nudging her clit as he slides it back and forth.
John sucks on each of Brittany's nipples, teasing both. Massaging her breasts and gently biting her hard nipples. As he pushes Brittany back down onto the sun lounger, all he can think about is getting his tongue onto her clit. Her beautiful shaved lips parting as she wraps her legs around him. A closely shaved landing strip leading to the honey pot.
John massages his cock as he moves down to heaven, kissing his way down from Brittany's breasts to her pussy. Licking up and down each inner thigh, teasing but not touching her clit yet. Her outer lips glistening from the foreplay. "Oh god John, please lick my pussy, stop teasing me, I want to get this done before one of the girls arrives home."
John did as he was told and started to lick the parted lips exposing Brittany's love bud which was swollen and ready for action. Just as John started, the door to the patio slid open and out walked Brittany's youngest daughter, Amy.
Brittany has 2 girls from a previous marriage, Amy, 21 and Heather 24.
"Well what have we here? Can't you two keep your hands off each other for 5 seconds, you are like two teenagers." Amy exclaims. "I must say Dad that cock is looking very inviting and mom you look gorgeous as always."
Amy continues, "Well, aren't you going to continue? Please, don't stop on my account. In fact, do you mind if I stay and watch? I've been horny all day."
Her mother replied, "Sure, you can stay and watch if you want, I don't mind but it's up to John, as long as he doesn't mind."
John couldn't believe what he was hearing from his wife, and thought I'm going along with this, "I don't mind at all, if your mother is ok with it, how can I say no? One condition though, if I may, you need to be naked as well" John suggested. He was thinking that Amy won't go that far, he also wants to see if she will. She might be interested in the week away even though the resort is clothing optional.
Amy starts to undo her top and unzips her skirt letting it fall to the ground. John stares at Amy standing in bra and g-string.
"Well, keep going." John says as he watches Amy undress. "You're not naked yet."
"Are you liking what you see dad?" Amy questions him.
"Let's see it all." John replies. Tempting Amy to see if she will actually go all the way.
John and Brittany often wondered if the girls had been listening or watching in the past when they were having sex. John got up and pulled Brittany up to kiss her again waiting to see if Amy was going to stay or leave. John whispered to Brittany "Do you mind if she stays? Might be our way to ask if she would like to go away to the resort."
Brittany replied, "Of course I don't mind babe, I want to see if she will or not as much as you do. Your cock seems to be harder watching her undress."
Amy comes over to where her parents are on the lounger. She turns around and asks, "Dad would you mind unhooking my bra if it's not too much to ask? I'm sure you have enough practice to do it quicker than I can," as she smirks.
John is not sure what to say, Brittany prompts him, "go on, show her your skill."
At that, John reaches up and in a hot second has pinched the clasp together and its unhooked. Amy turns around and lets the bra fall off her shoulders down her arms, exposing her firm young breasts. Amy's nipples are hard and her areola are larger than her mothers but her nipples are not as long as Brittany's. Amy has her mother's genes and her breasts are larger at 34D, Brittany's are a lovely 32C with slight teardrop shape to them where Amy's are upstanding and firm.
Amy leans forward toward John and says "So dad, you like what you see? As she pushes her breasts together with her arms, your cock seems to like it."
"I do indeed, they look delicious." John says, "but you still have something on," he reminds her.
Amy sits down on the lounger opposite her parents, as she does, she pulls her g-string up her slit and states, "I think I would like to keep them on for a little while, I like pulling them up to rub on my clit if that's ok?" As she demonstrates to John what she likes to do.
John gazes as the fabric disappears, her pussy looks lovely and smooth. Almost as if it was freshly shaven. if there is a landing strip it must be small he thinks to himself. Watching what Amy does, he looks towards Brittany as she nods, "Ok honey, that's fine, sit back and enjoy yourself."
John turns his attention back to Brittany, giving her nipples a suck as he kisses his way back to her wet pussy. He slips a finger in, "damn Brittany, you are wetter than before, has Amy getting naked got you turned on?"
