Since that stalker got me banned from E621, feel free to post this there with a link back to here.

Summer was ending, days were shortening, and Kate was on one last family trip to the beach.

Kate was undressing in the women’s changing room. She peeled off her slacks and polo, her toned body revealing itself as she went, until she was totally naked. Then she tossed them in the locker before turning to her mother, Claire, “Hey mom. You said you got me a new suit, right?”

Claire was similarly undressing. Despite being older Claire had maintained her own attractiveness to the point that mother and daughter could almost pass as siblings. Claire was shorter, true, but no less curvy and toned. “I did yes, dear” She said once she was also naked, “for both of us.”

Kate looked over the tiny piece of fabric her mother handed her. It was a bikini, bright green and just barely enough to be considered decent. Kate chuckled and slid the bottoms on. They seemed to only have a front, splitting into a pair of strings in the back that went around her tail. The design clearly trusted her tail to maintain decency on the back side. “You went all out huh, mom? OH, and can you help with the top? I’m always crap at tying these things.”

Claire was slipping into a similar dark blue number. It seemed to be of the same basic design, but almost matched her fur color, so the bottoms were almost not noticeable against her fur, “I figured we’d give the boys a treat.” Claire said coming over to her daughter and picking up her top. Claire reached around form behind Kate to pull the strings around her tying them then reaching back around to lift up the front and get it in place. In the process she gently caressed her daughters’ large bust sliding what little fabric there was over her nipples until it was in place then likewise tied around her neck to affix it, “Now can you help with mine?”

“Do you need help? Or do you just want me to play with your boobs” Kate said casually reaching over and giving her mother’s left tit a gentle honk.

“Ah you know me.” Claire said gently giving her daughter a bit of underboob pinch in response, “You like it too.”

“Perhaps” Kate grabbed her mother’s other tit and started to rub them both, “Our men will miss us if we take too long though.”

“So openly calling your brother ‘your man’ now?” Clarie asked.

Kate turned red, “Well, uh… well we … I mean there is a girl too.”

“Ah yes your girlfriend, who is also your brother’s girlfriend. Good cover…” Claire smirked, “I’m not judging though, I do hope you both will find your own mates eventually, but family fun is fine by me.”

Once both girls were dressed, they headed out. Kate’s brother, Daniel, and her father, Marcus, were waiting for them. Both wore more standard swim trunks, and were showing off their musculature to passing women. Though their attention switched back to Kate and Claire as soon as they arrived.

“Well, you two look hot as hell” Dan said looking both girls over.

“Indeed” Marcus agreed, “I think I may just want to take you both for a three-way.”

“Oh dad” Kate giggled, “If you did that Dan might die of blue balls.”

“No I’d be fine.” Dan said, “I’d just take you both next.”

“Gentlemen” Claire said holding up her arms, “There will be plenty of time for that later, for now let’s enjoy the beach.”

And they did. There was boogie boarding along the waves. There was sandcastle building, and finally some sun bathing on the beach watching the sun drift by. Kate was relaxing on her back, purring softy in the sun. Her purring intensified as a hand started to rub her belly. She wasn’t sure who’s it was and barely cared. Then a second hand joined the first and both started to rub her belly before sliding upward to her bust.

“Ohh boys, mmm getting handsy are you?”

“We aren’t both boys” Claire said.

Kate blinked and opened her eyes. Sure enough, one of the hands now sliding its fingers under her bikini to belonged to her brother, the other belonged to her mother. “Heh, you wanted to feel me up some more huh mom?”

“Always dear” Claire said lifting Kate’s top away entirely. Kate did nothing to stop her, and moaned at the touches instead, getting louder when Dan took advantage of the situation to lean down and start to suckle on one of Kate’s nipples. Claire soon followed, suckling on the other one, and Kate found herself moaning on her back with both her mother and brother on top of her, lips on her nips, and hands sliding rapidly down to her crotch. They both wiggled to remove their own bathing suits in the process.

“Ohh lord” Kate moaned out between gasps, especially when multiple fingers started to invade her pussy, “heh, which one of you is planning on fucking me first, this time?”

Dan pulled off Kate’s tit long enough to reply, “Perhaps I’ll take mom first. Make you watch after getting you all horny.”

Claire chuckled, “Normally I’d say yes, BUT maybe I should stick with Marcus for now.”

Kate was going to ask why, when suddenly Claire was all but tackled off of her by a very nude Marcus. He wasted no time pinning his wife down and slamming into her. It seemed Marcus couldn’t stand watching what was going on for one second longer and just had to get his. It worked out well though as Claire gasped and shuddered happily at the sudden intrusion. They both started humping each other hard, sand getting tossed around as they moved and kicked while going at it.

Kate smiled watching them go. Marcus’ nude body grinding on top of his wife, pumping her over and over while she moaned and squirmed under him. She was so distracted by what she saw that she didn’t notice her brother getting into place on top of her.

“AHHHH” Kate cried out in surprise as a familiar cock hilted in her with one hard thrust. Her legs instinctively lifted and spread in response, and her brother wasted no time gripping her hips and pumping away.

Kate transitioned to moaning and humping back after her surprise quickly waned and was replaced by intense pleasure waves from her mate working her over. Dan hugged his sister close and sped up, pumping harder and harder while she moaned louder and louder. Kate felt like she was being humped deeper and deeper into the sand of the beach and moaned all the more in response, urging him on and working his dick with her pussy muscles and clit hood.

It took almost no time for her to go over the edge and start to cum. She cried out as did Claire as both orgasmed, and their respective men responded by pumping them both full of their cum before all four collapsed in panting exhaustion.

After a long moment of purring and moaning in afterglow Kate turned to her mother, similarly laying on her back with an exhausted man as a blanket, “Say mom. Why did you say earlier that we should stick to our own men for now.”

“Oh that.” Clarie replied, “Well, more that I should only get filled by your dad for now. See I’mm off the pill.”

Kate blinked, as did Dan as he heard that, “Oh, my god why?”

Claire chuckled, “Well, now that you two have moved out, Marcus and I are going to try for another kid!”

“Oh… oh lord, really?” Dan said in surprise.

“Yep. We have the means, but don’t worry, once we know I’m pregnant I can have fun with you again.” Claire winked, “Or in the meantime, if you want I can suck you off.”

Dan blushed, “I think I’d like that.”
