-------------------
The hotel room was quiet to the point where the rustling of the duvet seemed deafening. Anna tossed and turned and eventually threw it off. Her sister, Mia, who had already kicked hers away, was still trying to sleep on the other side of the double bed.
"Stop moving!" Mia groaned.
They had both spent the night topless in very skimpy panties.
"We've been asleep all morning," Anna groaned back. "I can't just lie here anymore."
They weren't twins, but you'd be excused for thinking they were. They both had straight, blond, shoulder-length hair and were endowed with very similar large, firm breasts and perky asses on their tight bodies. There was one year between them, and Anna was the big sister at 23.
"Noooo," Mia continued to whine. "No talking! I'm hungover. I'm too horny to think. I can't take it. I just want to get away."
Yesterday evening the sisters had been to a small town wedding.
"Yeah right, we're fucky!" Anna remembered out loud. "We were supposed to fuck someone last night and make it better!"
Now they were staying outside town at some sort of nature resort that doubled as a hotel. A wedding was big business for such a small place.
"Yeah, well that wouldn't have helped," Mia complained. "I'm too sick and horny when I'm hungover."
The sisters had shared a naughty streak while growing up, but they had been raised with authority, keeping them well-behaved and even shy around each other. Then, Anna had moved for college with Mia following the year after, although they had never really reconnected.
Meeting up now, going to this party, Anna had sensed a new closeness. Over three days -- planning, traveling, and partying -- they had shared memories and secrets. The latter had seemed to excite them both quite a lot. Anna had never known just how wicked her little sister could really be. In just a few days, they had gone from detached sisters to intimate best friends.
"Hungover horny?" Anna smirked as if confirming a suspicion. "I guess it runs in the family. I can never control myself either."
If you looked close, you'd see both pairs of panties being soaked through the hems of the crotches, glistening from purely physical responses to the hangovers.
Anna was actually more aroused than usual, and she wondered if it was from lying so close to a smooth, perfectly curved, almost naked body. You weren't supposed to feel sexy things about a sibling, but it was impossible to deny that those bare tits and that barely clothed ass were fascinating. What if Mia felt the same way? Anna's nipples were hard as pebbles, aching for touch, and the idea of Mia wanting the same kind of touch made her big sister unreasonably excited. She had to knock these thoughts out of her head before she said or did something stupid.
"Is it only when you're hungover?" Mia asked with a naughty interest. "Because to me, I kind of have to... distract myself, all the time. You know. And when I'm hungover, all I think of is sickness."
"Yeeahhh, sicky feels!" Anna agreed. "Days like this, I just wanna do and say the sickest fuck-stuff I can come up with."
It wasn't really a secret between them that Anna was obsessed with wicked words and perverted playing, and now she had an idea that Mia might be the same. Over the last days, they had already spent whole conversations in baby-talk, and you could tell they both got off a little bit on it. But right now they appeared to have hit a limit. There was a whole day in a bus ahead of them, and it wouldn't be fun spending it crazy from arousal and frustration. They sat in silence and wondered how to handle their aching heads.
Finally, Anna had an idea that gave her some hope. It was a long shot, and it was desperate, but she really couldn't see that she had anything to lose.
"Maybe we don't have to sit in a bus all silly and sick," she ventured, sitting up now. "What if we ask to stay?"
"But they're closing," Mia protested. "Season is over, remember? They only stayed open because of the wedding."
"Get dressed! We're going down to ask!"
And the two of them walked down through an almost empty establishment. It turned out they had missed breakfast, and they had missed everyone leaving, and they were well on their way to miss lunch by now.
The only member of staff was one woman, who came out from a room behind the counter to talk to them.
She was about 50 years old. She was heavy in the kind of way that made you imagine perfect massages. Unfortunately, they wouldn't be getting any massages today, because the spa was indeed closing for the season, and the stocky woman with fat thighs and enormous breasts would do the work, which was mostly cleaning, she explained. She offered them sandwiches left over from breakfast while she considered their request to stay another night.
"I'll stay here until tomorrow, cleaning out the rooms," she pondered. "I guess you could use the spa and I can clean your room last."
This was pretty much all the sisters could have wished for. A horrible day of hungover travel was turning into an afternoon with a spa all to themselves.
"So how does it work out there?" Mia asked. "Do we get some kind of bathing suit?"
"Well, you can, for the pool," the woman replied. "But now you don't really have to. I'm washing all the rentals up for storage. You'd be doing me a favor if you went without."
"What, we can go naked?" Mia asked in shock.
"In the sauna you'll go naked either way," the woman replied. "Today, it's fine for the pools too. The only one you might see in there is me, cleaning. You decide!"
Anna felt no need to question things, and Mia seemed to just appreciate their good fortune as well. Their hostess appeared to wear nothing but a very comfortable and white robe, and now she left them with robes of their own and pointed them in through a door, leading them right into the jacuzzis. She explained that they didn't have to shower unless they wanted, because no one else would be using the pools before they were sanitized for winter.
"Just take anything you want from the fridge!" she called out after them as they walked in to the warm pool hall. "I'll put it on your tab."
And then the siblings found themselves alone in a big hall with two heated tubs and a big pool with a number of strange fountain-like contraptions. Although now, the whole room was quiet, because everything was activated by buttons or sensors. The hall had enormous windows out to a sunny lake just outside. The effect was startling, making you feel that you were out in public. The idea of taking your clothes off in this environment felt perverse.
They changed while trying to be discreet on instinct, giggling to each other a bit about how weird it was to get nude for the whole world to see. Once in robes, they spent a few minutes walking around, inspecting the gigantic wooden deck and sunchairs outside. Beyond the lake there were trees. No one was around for miles.
"Look at me!" Anna whispered, and when Mia turned around she saw her sister's robe pulled aside to reveal a naked, stiff-nippled tit to the chirping tits of the forest.
They both grinned. They were building courage.
"It's wicked," Mia responded. "It feels hot to have nothing on under this."
In response, Anna pulled the belt of her robe open and showed both her breasts and her pubic hair for the surroundings. She gasped from the breeze on her naked skin. It was very liberating and intense to be so exposed and so completely safe at the same time. She could feel wetness between her slippery labia, and knowing Mia could just look right at it made everything twice as arousing.
Then, they turned back inside, going for the pools, and by the time they dropped their robes on chairs their last modesty had disappeared.
"Stare much?" Mia blurted out when she noticed sister-eyes glued to her well-trimmed crotch.
"You're so horny you're dripping," Anna taunted back without managing to hide her excitement.
It was really almost impossible not to stare at the glistening strand of lubrication dangling down from Mia's meaty cunt lips. Anna didn't have to worry about being too horny today, since her little sister seemed to be in an even worse state. To be fair, you could clearly see Anna's cunt glistening in this bright daylight too. The biggest difference was hair everywhere, soaking and smeary all around the fuck slit.
"Yeah, I'm reeaally bad right now," Mia groaned back. "I just wish I was by myself so I could do something about it, all fucking day!"
"I'm the same," Anna admitted. "Maybe a bath can distract us. Maybe we can go to the room in turns to... relieve it. Or a drink could fix it. At least, I want a drink now, but alcohol only makes me more cunty."
She walked up to the nearest bubble bath, which started on its own.
"Well, you gotta do what you gotta do," Mia answered cryptically.
Anna experienced the heavenly sensation of lowering her naked body into the warm, tickling bubbles, while Mia came walking over from the fridge with a small bottle of sparkling wine and two plastic cups. She popped the cork and poured, spilling on the floor, before she lowered her smooth ass into the water as well.
"Oohhh, yeaahh, it's amazing," she verified.
Anna invited her sister to sit down side by side and enjoy the view, and Mia accepted the offer by scooting as close as she could, pressing their bodies together. The feeling of naked flesh caught Anna by surprise. It felt luxurious to be here, and it felt shameless to be naked with your sister. Mia handed over the cup.
