Florence sighed and laid back on her towel. Normally a week at the beach would be a treat. But this time around she was bored.
And horny. Very, very horny.
She sighed again and looked over to where her parents were sitting with her two aunt's. They were Kelly's sisters, but Melisa had grown up with all of them, and they had been one big family for a long time. They were laughing, sipping cocktails, and enjoying the sun. Florence should've been doing the same, but all she could think about was one, or both, of her mothers dragging her back to their bedroom and fucking the shit out of her.
She should make the most of it, she supposed. At least her cousins were hot. The cousins in question were on either side of her, soaking up the rays. Steph was everything Florence was not, thick and curvy where Florence was slim and flat. Dark and tan where Florence was pale. Her mother, Cynthia, was actually Kelly's oldest sister, but Steph was the youngest of the cousins, just barely nineteen, and just done with her freshman year of college. She'd changed up her look since the last time Florence had seen her, shaving the sides of her head but leaving the rest of her hair long so that it trailed down her back in an inky waterfall. It was insanely hot, and Florence had blasted her clit in the shower the night before thinking of wrapping that hair up in her hands while Steph ate her out.
To her other side, Drea stirred, muttering something about tan lines. Florence could only roll her eyes at her other cousin. Daisy Rae had gone through a couple of name changes before settling on Drea. Just Daisy, just Rae, D-Rae. But she'd landed on Drea in highschool and it seemed to stick. Her mother, Gia, had won a hefty sum of money in her divorce. Enough to buy the beach house they were all staying at, and enough to ensure that Drea never had to find a real job. So she was making a run at being an influencer, which mostly seemed to mean wearing slutty outfits and taking selfies. Florence didn't mind the slutty outfits, and she was massively jealous of Drea's bikini. The top was cut in such a way that most of the bottom and sides of her generous boobs were exposed, while still somehow providing support. And the bottom was small enough that it was very clear that Drea had been waxed recently. Florence's bikini was practically conservative in comparison. She'd had to buy it just for the trip. All the ones she wore at home were inappropriate for a family trip, or so she'd thought. Even at home she only wore them in the privacy of her family's pool.
Well, she would wear them until one of her moms came out, peeled it off of her, and made her cum so many times she forgot her own name.
Not much chance of that happening out here. Her aunts and cousins were cool, but probably not that cool. She sighed again and slathered on more sunscreen. She would burn given the slightest chance, and wanted to avoid that at all costs.
Later, after a long day in the sun, they were back at the house. Florence's moms, her aunts, and Drea were all taking naps. Everyone was planning on a night out at the club, and wanted to rest up. The perfect time to jump in the shower and frig her clit until she couldn't see straight.
She was rounding the corner on her first orgasm when Steph barged in.
"Hey cuz, do you want to share?" Steph stopped short and looked down at Florence's body. "Oh, shit. Were you jerking off?"
Florence slid her fingers out from her cunt and licked them clean before answering. "I was working on it. Why are you in here?"
Steph pushed her way in, sliding past Florence and under the water. "I just thought we'd share, like we used to, you know? Plus we can conserve water this way."
"We used to share baths when we were kids, I don't know about it now." But Florence didn't mind that much, Steph was fun to look at. "Goddamn, Steph, your tits are insane."
Steph turned and slid her hands under her breasts, lifting them slightly. "I know, right? J cups, if you can believe it. I hit puberty and they just ballooned overnight."
"I don't get how they're that big and still look that good." Steph's huge tits had just the right amount of sag, and a perfect shape. Her little nipples were pointing slightly up, capping dark areola the size of quarters. Florence couldn't help herself, and reached out to cup one of them, running her thumb over Steph's stiff nipple.
Steph moaned a little and leaned into Florence's touch. "I'm glad you think so, I've always been a little self conscious about my body."
"Are you kidding? You look like some sort of Sumerian sex goddess." Florence wasn't exaggerating. Steph had her huge tits, and the big round ass and thick thighs to go with them. But in-between her waist was slim and snug, almost comically tiny, with just a hint of abs. And like all the women in their family, she was tall, 5' 10", and it looked fantastic on her.
"You really think so? I like hearing that. I worry that I look fat." The shower they were in wasn't huge, but it wasn't tiny either, and there was plenty of room for both of them. But suddenly Steph was pressed right up against Florence. "I love your nipples," she said, reaching out to tweak one of them. "Just so big and plump. I wish I had nipples like you. I'd put rings through them and never stop showing them off."
At this point, both girls were pressed against each other, faces barely an inch apart. Steph had both of Florence's nipples caught between a finger and thumb. Florence was cupping Steph's tit with one hand, the other down on her flank grabbing her ass. It was inevitable that they would spread their legs and make contact. They moaned together as each clit found a thigh to grind on. The two cousins gazed into each other's eyes, breathing in concert as they began to grind into each other.
Florence released Steph's tit and grabbed her by the nape of her neck, pulling her forward until their foreheads touched. The two girls locked eyes as their hips rocked, stiff clits and slick lips grinding across each other's thighs. Steph came first, a ragged groan spilling out of her mouth, but Florence was right behind her. The climax quaked through both of them, their cores flexing and their thighs quivering as their cunts drooled out a river of sticky lust that was whisked away by the shower.
