At the time of this story, it's actually been a while since my rival, Kim, had tried to strip me and humiliate me, which naturally made me simultaneously disappointed and anxious for when the next (probably successful) attempt might be.
That isn't to say that I wasn't on the receiving end of more stripping and humiliation; my other classmates and acquaintances seemed to be picking up more of the slack that had been left by my rival's absence.
It did mean I was pretty excited when I got a call from my rival, inviting me to a pool party on the weekend, I knew in my gut that this party would probably involve an attempt to humiliate me, possibly in front of a whole group of people.
I got ready by putting on a nice skimpy bikini, it wasn't the fact that it was skimpy that got me excited about it, it was that the strings were quite flimsy actually, which means that it would make it easy to remove by accident, and this might be the perfect time to use it, in fact, it was similar to one I'd used previously to expose myself on swimming challenges against Kim, since she was on the swim team, the outcome was a given humiliating and naked loss for me.
I also put on a pair of jean shorts and a simple t-shirt on top for the trip over, as well as a pair of flip-flops, my rival's house wasn't that far, so I could walk to it quite easily.
When I got to the party, I walked into the backyard to find that everyone was already in the pool, that included Kim, two of her girl friends from the swim team, and the two boyfriends of said girls, as well as maybe another four or five girls and boys that I didn't know.
"Come on in Luna, the water's great!" Kim said, swimming in the pool.
I looked around, there didn't seem to be a place to take my clothes off, at which Kim seemed to sense my hesitation:
"Just take your clothes off here, we wouldn't mind." Kim said, a grin forming on her face, all while mine started developing a decent blush.
even though I was only taking my shorts and shirt off, it still felt pretty embarrassing to strip in front of Kim and her friends, all watching me quite intently, it was almost like I was giving them a show, I was pretty aroused already when I finally took my flip flops off and tried to get into the pool, but Kim stopped me before I took even two steps:
"Take your bikini off Luna." I was surprised by how openly she just told me to do it, so much so I was flustered and didn't know what to say "We're all naked in here, so you have to strip too."
I looked down into the water, but from my angle, I couldn't tell if she was lying; they had all strategically chosen to hang by the pool's edge not to mention that none of the girls seemed to be showing any straps to indicate if they were wearing a top, however, I didn't really care, she was probably lying, and it was my intention to get stripped anyways, so I was loving the idea that I would be falling for such a trick.
I reached back and undid the flimsy strings on my bikini top, putting it with the pile that comprised the rest of my discarded clothes, exposing my breasts to everyone, already my nipples were rock hard, and I could feel the eyes on them as I stood there.
Next I did the same to my bottoms, pulling the strings apart and placing them on top of the pile, now I was standing completely naked in front of Kim and her friends, I hoped my pussy wasn't wet enough to give my arousal away, but I was sure I was quite turned on at this point.
"Alright Luna, jump in." And with that, I jumped into the pool with everyone else.
As soon as I was in the water, I saw Kim climb out of the pool, and just as I expected, she was wearing a swimsuit with a strapless top. she immediately collected my clothes.
"It's getting pretty easy to strip you, Luna, now step out of the pool." Kim watched as I obeyed her command, I stepped out of the pool, now fully aware that I was the only one naked there, wet, humiliated and extremely horny "Maybe you'd actually strip on command from now on?"
I blushed, hard. The idea that she would just call for me out of the blue and arbitrarily demand I strip for her and her friends made me feel like a slut, especially since I know I would seriously consider it.
