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."
