My name is Ming and I just turned 19 yesterday. My family and I moved to Switzerland from China a few months ago. I woke up this morning feeling nervous and excited and with a really hard penis. The reason for my excitement - we'd all been invited by my parents friends Jia and Tom to join them at a spa today. This might not sound that special but it's a nude spa it and would be the first time my twin sister and I would be naked in public!

Actually, that's not totally true as I once visited a bathhouse in Beijing with my father - but that had been men only. The place we were visiting today was mixed! When we'd spoken about it, I'd acted cool but in reality I was incredibly aroused at the idea of seeing real naked women for the first time. At the same time I was terrified of being naked myself. OK, I'll admit it, I'm still a virgin and the only naked women I've seen have been on the internet. Sure, I've caught the odd glimpse of my mother and sister but I've never seen them totally nude or for longer than a few seconds.

My parents spoke to us last night and told us a bit about the spas they had visited before. They'd asked if we had any questions and both Siyue and I had said "no, everything's clear". What a lie! I knew it wasn't clear at all for me and I guessed it was probably the same for Siyue, but maybe it's easier for a girls.

I decided I better do something about my erection so I lowered my pants and grabbed an old sock from the floor pulling it over my cock like a condom. I pictured myself naked in front of my mother, sister and Jia (who I thought was really hot). I imagined them all looking at my cock and being impressed with its size and wanting to touch it. After a few tugs I filled the sock. It felt better but my erection barely softened and I started to worry I'd be hard all day! What if I had a boner in front of everyone!?

As I lay there contemplating this, I heard a knock on the door. It was Siyue asking if she could come in. I quickly pulled up the blankets and lay on my side to hide my arousal before saying "Sure."

She came in and closed the door, then sat on the edge of my bed, I could tell she was worried about something and said "What's wrong?"

"Can I ask you something personal?"

"Ummm, I guess so."

"How do you feel about today? You know, about being naked?"

I was surprised by her question. Despite being close we'd never really spoken about anything like this before. "I'm kind of nervous, what about you?"

"Me too, I could hardly sleep last night thinking about it."

"But you said you always wanted to try skinny dipping and being naked was no big deal!"

"I know what I said but that doesn't mean I'm not worried about it. I've never been naked around anyone except mum and after sports at school and it was always just girls. I've never even seen a naked man before."

"Yeah, well it's the same for me! I mean, I've never seen a naked woman."

"But I've seen you peeking at mum and me sometimes!"

I blushed and said "I never really saw anything properly! You must have also seen dad before?"

This time she blushed "I always got embarrassed and looked away if I caught him undressed."

"Well it's too late to back out now, we both asked to go and now it's going to happen!"

"Just promise you won't make fun of me or laugh at me."

"What are you talking about?"

She blushed even more and began to chew her thumbnail which I knew was a sign that she was really anxious. "It's just... I'm not the same as other girls..."

"Huh? I still don't get it?"

"You know, here..." she said, pointing at her chest, "I got teased a lot at school, I'm not like mum or most of the girls."

She was almost crying now and I didn't know how to react, "Oh... um... well, I'm sure you're fine and I promise I won't do anything mean." I thought I'd cheer her up and added "You know all my friends think you're hot!"

"Hmm, well, that's just because they haven't seen me naked." She sobbed.

I glanced at her chest and couldn't make out anything through the thick and loose fabric of her pyjama top. I'd never really noticed anything unusual about her breasts before as they were always hidden by a bra or towel and I guessed she was probably just worried they were smaller than our mum's.

I sat up and put my arm around her "Don't be silly. Anyway, today it'll just be mum, dad, me, Tom and Jia. No one else will know who we are and we'll probably never see them again, so who cares!"

She considered this and then seemed to cheer up a bit, "You're right and it will be exciting!"

"Yeah!" I let go of her and lay down again as she go up to leave.

At the door she turned and said "Thanks Ming, it helped talking to you."

"No problem!"

I followed her gaze and noticed her she was looking at the lump my boner was still causing in my bedsheet. I blushed and quickly rolled onto my side again.

"Well, see ALL OF YOU later then!" she said as she exited.

After she'd gone I peeled back the sheet and pulled of the now very sticky sock. My penis remained stubbornly hard and I really needed a pee. I thought about risking the walk to the bathroom but then heard voices in the corridor and decided to wait a bit longer.

"Ming, Siyue, get up!" called mother.

I've been UP for ages already! I decided to take my pyjama top off and use it to cover myself. I stood up and tucked my penis under the waistband my pyjama shorts and held the top loosely in front. This would have to do and I really couldn't wait anymore to empty my bladder.

I walked out my door and made it to the bathroom without meeting anyone. I quickly went in and locked the door. Assuming the position before the toilet bowl I pushed down my resisting cock and tried to pee. It was very uncomfortable and almost painful and I wasn't rewarded with a single drop.

This is hopeless! I decided to brush my teeth and wash my face in the hope things would calm down. No such luck! I was left with no other choice but to jerk off again. I grabbed some toilet paper and held it at the ready in my left hand then used my right hand to perform the well-rehearsed motions needed to come. To help things along I closed my eyes and tried to picture Jia naked.

The image that formed in my mind was of a tall, slim lady with smallish breasts and a nice round bottom. I pictured her bending over in front of me and wiggling her bottom seductively. That did the trick and I covered the tip of my spurting cock with the tissue until the last drop was squeezed out.

I was relieved to feel my penis begin to soften and once it was facing down I was able to aim and release a long stream of piss. It felt almost as good as the orgasm! I shook the last drops off and flushed.

"Hurry up in there!" said Siyue.

I washed my hands and then opened the door the let her in.

"Finally!"

I didn't respond and went to my room to dress.

Breakfast and the rest of the morning passed quickly and without anything noteworthy happening. I couldn't help but look at my mother and sister and imagine what they would look like naked. I knew my mum had largish breasts but they were always well hidden by her underwear. When I looked at Siyue I could clearly see the swell of her bra under her t-shirt and couldn't really understand what she was so worried about.

As we were packing our bags I realized that I hadn't been swimming for ages and that my swimsuit was pretty old. I hoped it would still fit properly and wasn't too unfashionable. Siyue looked like she had the same problem as she held up her suit and said "God, this thing looks terrible! I haven't worn it since middle school."

Our mother looked at the suits and, as mothers always do, said "They'll be fine..." She then added something that most mothers probably don't "... and anyway, you won't be wearing them for long!"

It wasn't long before the doorbell rang - Tom and Jia had arrived! My heartrate increased and my palms were sweaty as we went down to meet them. Jia was looking especially nice and I felt my penis swell as I realized I would be seeing her naked in a couple of hours. I climbed into the third row of seats in their car next to Siyue. Jia and mum were in the row in front of us.

During the drive I let Siyue do most of the talking. I sometimes leant forwards to better hear what Jia or mum were saying and realized that when I looked down I could see the shape of Jia's breasts quite clearly as her t-shirt was being pushed down by the seatbelt and she wasn't wearing a bra. They looked smaller than I had pictured but she seemed to have really big nipples and I could see the impressions they made in her shirt.

I tuned out of the conversation for a while and enjoyed the view inside and outside the car. My attention returned when I heard Siyue ask if anyone had ever made any comments about our mothers or Jia's bodies. Mum said it hadn't happened to her but Jia said she'd experienced it once. She then went on to tell a story about what happened in a hotel sauna when some guy made some rude comments about her.

My cock stiffened as I listened to how she had purposely exposed herself to get the guy aroused and how he was ridiculed when others had seen him. It was really funny and I laughed along with the others, but at the same time I was in a panic that this would happen to me as well!

Jia went on to explain how we shouldn't stare at other people or make comments about them. When she was done I decided to ask about what happened if a man got aroused.

It was a relief to be in the back as I was embarrassed to ask and glad they couldn't see me blushing. Jia just said that if it did happen, people usually ignored it and the guy with the problem just covered himself with a towel until it was over.

Siyue laughed and made some comment about her being glad that she wasn't a boy. I ignored her and continued to think about what I'd do if I got hard. Jia turned around in her seat and smiled at me saying I shouldn't worry about it because everybody knows that young men can't control these things. I smiled back and thought to myself that she's really nice.

Time passed quickly and soon Tom was parking the car and everyone clambered out. We went inside the building that looked old on the outside but was brand new inside. Once the tickets were bought, Tom asked Siyue and me what we wanted to do first. It looked like the special connection between twins was working as we both answered "the pool" at the same time!

Now the next hurdle was here, we had to get changed. I was imagining some big open changing room where everyone had to get undressed together and was relieved to see that there were small lockable stalls. I took my suit from my mum and stepped into an empty stall.

OMG! This is worse than I'd expected. The suit was small and tight and when I looked down I could see a clear imprint of my penis. If I got hard wearing this thing it would easily be visible and in the worst case something would even break free. There was nothing I could do so taking a deep breath I opened the stall and stepped out.

I was first and stood waiting for the others at the entrance to the pools. Tom and my dad were next followed by the 3 ladies. I tried my best not to look but my eyes were drawn to the three women as they approached. My mother and Jia were both wearing bikinis but their bodies could not have been more different. My mum had really big breasts and quite a lot was uncovered. They jiggled around nicely in the bikini that was struggling to contain them.

Jia's bikini on the other hand seemed to serve no purpose but to cover some skin. As I'd noticed in the car she had very small breasts that didn't need any support. Her nipples however looked huge and caused large cherry sized bumps in her top. Her small breasts suited her slim body and she looked very sexy as she approached us. I looked forward to seeing her from behind as the small triangles that made up the bottom half of her suit wouldn't cover much!

My cock was growing and I wanted to get into the water as quickly as possible. I tore my gaze away from Jia and looked at my sister. She was the only one of the trio not wearing a bikini and she looked to have a similar problem to me. Her red suit was too small and the fabric looked worn and thin. She blushed as she noticed me looking at her and I couldn't help but check out her chest. I was surprised by how different it looked.

Instead of the round bumps about the side of half an orange that I usually noticed when she wore a tight top there were just two pointy cones sticking out. I wasn't quite sure what to make of that and wondered if this was what she'd been so worried about. I waved her over and we both rushed ahead to get into the water.

The pool had a nice temperature and it was great fun playing around with Siyue. Her suit became slightly transparent when it was wet and I couldn't help but stare at her breasts. She noticed me looking and said "Stop staring at me like that!"

I blushed "I'm sorry, I just can't help it. You look different than usual."

"You promised you wouldn't be mean!"

"I'm not being mean!"

"You said I look different and you keep staring."

"I keep staring because you look great."

"What?"

"Look, I'm your brother and I'm not meant to feel like this but I think you look hot. There, now I've said it."

Siyue looked surprised "Are you making fun of me?"

"No."

"So you really think I look good?"

"I've already admitted it."

"But why did you say I look different?"

"I mean, um, usually your, um, your top looks different to now."

"That's because I always wear a padded bra."

"Oh... well how am I supposed to know that?"

Siyue seemed pleased with my answer and stopped the interrogation. "Shall we try the slides again?"

I was glad to change the subject and followed her out of the water and up the stairs. She looked good from behind as well and I had to look away before the bulge in my tight trunks became even more noticeable.

The slides were great and each time we rode them Siyue's suit seemed to pull tighter and expose more of her body. She noticed me staring again but this time she didn't complain and I also caught her eyeing my crotch a few times. I noticed that our parents and Tom and Jia had already left the pool and were lying on some loungers outside.

"I've had enough, shall we go outside?" I said.

"OK"

We left the pool and walked outside to join the others. I immediately noticed my mother and Jia lying on their tummies enjoying the sunshine. They both had much bigger bottoms that Siyue and Jia's especially was stunning. Her small suit had slipped between her fleshy cheeks and it almost looked like she was naked. The two large globes stood out proudly and I imagined grabbing them and pushing them apart to reveal the treasures hidden beneath. My mum's bottom was much flatter and hardly raised up above her back. Jia's is a lot sexier.

Tom said "So are you guys ready to try a sauna? It's quite busy so we can just take a look first and if it's crowded we can head over to the quieter part."

We all agreed and walked to the sauna entrance. "This is it!" I thought to myself and but was disappointed when I saw the long queue. Tom said "it's too busy and there's no point waiting in the queue, let's have some lunch and then go to the high-end spa, we can always come back here later."

Oh man, now I'm going to have to wait even longer to see some naked women. I followed the rest of them to the small restaurant and ate my meal as quickly as possible. I was glad to see that no one was very hungry either and just had small dishes. About half an hour later we were heading to the entrance of the other spa. It was much quieter here and there were no other people around.

We scanned our bracelets at the turnstile and walked through a door with a poster showing crossed out swimwear, cameras and phones. Jia took the lead and led us into a changing area. This time it was just a room with a few benches, hooks and cubbyholes. There were no stalls and nothing to hide behind!

I froze. My parents, Jia and Tom began to strip off their clothes as if it was nothing special. I didn't know where to look. I glanced at Siyue and saw she was also just standing there staring.

I saw dad and Tom's cocks and noticed that Tom had no foreskin. They didn't hold my attention for long as far more interesting things were being revealed. Jia had removed her top and I saw my first real live breasts. They were very small (as I had expected) and were topped by large brown nipples that poked out a couple of centimetres. My mouth felt dry and I licked my lips as she turned around, bent over and quickly pulled the bottom half off.

This was fantastic. I was standing a few meters away from a really hot women and SHE WAS NAKED!! I noticed some movement next to her and realized I had missed my mother stripping. She was already placing her suit into a cubbyhole and was totally naked. Her very large breasts were hanging down and swinging gently as she reached over into the cubbyhole. Her nipples were smaller than Jia's and only stood out a little bit.

Two lovely bottoms wobbled nicely as their owners moved around and I had the opportunity to compare their shape when standing. Jia won again as hers bulged out nicely whereas my mother's was rather flat. When they finished stowing their gear they both turned and faced me.

My eyes dropped to the two naked pussies before me. Jia's had no hair at all and I could see everything! There were two brownish wrinkly looking flaps hanging down I had the sudden urge to reach out and pull them apart. My mother on the other hand had quite a lot of longish black hair. It covered everything and I couldn't make out anything underneath.

When I looked up I noticed the four of them were staring at Siyue and me. Tom looked like he was about to take Jia's hand and leave the changing area but then my mother said "Wait!" before switching to Chinese and telling us "Don't just stand there and stare! Get undressed."

I could tell she wasn't happy so without really thinking about it I quickly pulled down my pants. I was surprised that I wasn't fully erect and quickly moved forward to stow my suit before standing next to my mother and turning around. Poor Siyue wasn't as quick to react and was now the last one dressed.

She had an audience of five watching as she slowly reached up and pulled down the straps of her top before turning away from us and pulling her suit down. The suit was wet and tight and it was difficult for her to get it down. Her small, pale bottom was revealed but the suit got harder to move as it bunched up at the top of her legs. She bent over as she pulled on each side trying to get it off.

My eyes widened as her butt cheeks parted and I could see her small pink asshole and pussy. She had hardly any hair and I could see every detail. Unlike Jia she had no protruding flaps and just a lovely looking cleft.

I felt my cock expand rapidly and stand straight up with the tip pushing past my foreskin. It was harder than ever. Oh shit! This is so embarrassing and my parents are sure to kill me. Things got even worse when Siyue turned around and tried to cover herself. It was a hopeless endeavour and I could still see her breasts as clearly as everything else. They were very unusual and I'd never seen anything similar when looking at pictures of naked girls on the internet!

There weren't really any breasts at all, just these giant nipples coming out of her chest. Pinkish in colour and shaped like fat cones - they were fantastic!
