It was a sunny day in the tropics. My family was taking a vacation in a resort notorious for its sandy beaches and vast cave systems. During our stay there, my parents wanted some 'alone' time to themselves (I knew they just wanted to fuck around, literally) letting me and my twin roam free around the resort with some cash. We were already 18 and responsible enough to look for ourselves, so we immediately did what kids our age did.
Janice, my twin sister, and I were white-skinned people just like our parents. Most people didn't rarely think us twins, seeing as Janice had waist length red hair like our mom and I had blond hair like my dad. My eyes were green like my mom's, while my sister had light blue eyes with flecks of green in them.
You could see us being siblings, but definitely not twins. It didn't help that I was 6'2" while Janice was 5'10" tall. Sometimes people even mistook us for a couple, especially with how "cute" we looked together.
The first three days we spent our time hanging out with the locals. They loved us, and I especially liked how the brown ladies of South East Asia would just flock to me like moths to a flame. I spent most of my time during those two days of freedom flirting with the women but not once did I get to score, which left me very frustrated.
My sister must've been hit on too, but she was the shy type and didn't do well under all the attention from the guys. She just wasn't used to it, I guess. To be fair to her though, her chest was flat as a board and her body being naturally skinny didn't help her cause. The only thing she had going for her was her heart-shaped ass and long legs, which was more than enough for the horny bastards looking to score with some foreign flesh.
By the fourth day Janice had had enough of the attention. She begged me to stay with her while she played under the sun, and being the caring sibling I was I obliged. Having a guy tagging along definitely helped keep other horny boys away.
On the fifth day, we spent most of our day relaxing in the hamocks under the shade. Trying to get a tan was pointless for Jan, seeing as all it would do was make her slightly less white and more red. I wasn't really one for tans, so I didn't bother.
I was wearing my Hawaiian print swimming trunks, while Janice wore a pure white string bikini top with a floral skirt for bottoms. I remember that I found this strange as she usually wore the matching bottom pair for the top, just like the day before, but didn't mention it.
What I also found strange was that Janice refused to go swimming that day. This was weird because my sister was an avid swimmer, diving into any body of water any chance she could get. I didn't ask why, but if I had it would solved a lot of problems.
The afternoon was spent just walking around, looking at the sights and people. Janice was the one who found it first, a cave entrance with a small shop in front of it.
It looked like one of those cave tour things I saw in the brochure. Janice wanted to go, and I remember thinking, "Why not?"
We lined up dressed in our swim wear, like most of the folks in the line.
"For two people, please." My sister told the pretty girl manning the stall when she asked how many there were in our group.
"Would you like the couple's discount, ma'am?"
"Oh, we're -"
"Sure! Right, dear?" I interrupted Janice. One of the most important things in life was a good discount.
The stall girl smiled and took out a basket filled with dried mushrooms. "Then, can you please feed these to each other using only your mouths, sir?"
I shrugged, and did as told. Janice seemed embarrassed about it, but ate the mushroom anyways. Our lips touched for a short moment, and I couldn't help but notice how soft her lips were.
A lot of our problems would've been none existent if we just didn't take the discount, but I didn't know that back then.
We followed the map given to us for about ten minutes when Janice suddenly pointed at a tunnel to our right.
According to the map, it lead to a "Crystal Cave", but there was a no entry sign put up in front of it.
"Come on, Jay." My twin said to me with pleading eyes. "Please? It's almost our last day here. Don't you want to do something daring?"
I was a sucker for following her. We walked the long tunnel until we reached the end.
The Crystal Cave was exactly what the namesake would let you picture. The walls and ceiling were covered in beautiful crystals that glittered from the sunlight pouring through the small holes from the top of the cave.
"Wow..." I exclaimed, admiring the sight.
"It's beautiful." My sister was as awestruck as I was, a goofy smile on her face as she stared at the crystals.
Her face was flushed red, and I thought it was from the happiness at getting to see something like this. I smiled and my eyes instinctively zoomed in on her lips. They were pink, and opened slightly like she was panting. She didn't look exhausted, so I didn't say anything. Next, they moved to her chest, which were still flat A-cups.
I shook my head when I started getting thoughts of fucking Janicr. Sure, I just realized my sister was hot, and sure, I was checking her out, but that didn't mean she wasn't my sister.
Our joy only lasted for a few minutes when we started hearing voices coming from the tunnel we just came through. We were trapped, and both of us looked at each other with fear in our eyes. There was a clause in the contract that we were made to sign at the cave entrance that guests who didn't stick to their tour plan, or guests who lost the ID tag they were wearing, were fined what amounted to $30 in US currency.
It was pocket change, but we didn't want to get in trouble.
"Told you this was a bad idea." I whispered to Janice while we looked for another way out.
"Shut up..." She hissed, face red from guilt, exploring the other end of the cave. "... Just look for somewhere we can hide."
The voices were getting closer, and I was afraid that there actually was no place to hide in when I found it. There was a small crevice at a dark corner of the cave. It looked like the roof of it curved downwards towards the end, but I figured we could both fit if we got on all fours and squeezed in tight.
"Jan!" Jan was a nickname only I was allowed to call my twin. "Over here!"
I motioned over to the small hole in the wall I found and squeezed in as far as I could go. I had to basically be in push-up position so my twin could fit. Janice followed soon after, slipping in between my arms. There was so little space between me and the rough floor that she had to lie flat on the ground. It was such a tight fit that I felt her skirt flip against my stomach when she pushed herself in.
"Can you move a bit." Janice squirmed underneath me, trying to get comfortable. "It's too tight."
"I can't. The tunnel doesn't go that deep." I was also trying to get comfortable, the strain on my arms wasn't much now, but I knew it would only grow in time.
We settled down when the owners of the voices could finally be seen. It was a tall white guy, and some petite brown chick he was with. They walked in holding hands, admiring the view.
"Are you sure this place is off-limits?" The white guy asked.
"I told you already," the brown lady replied. "There was an accident a couple days back so they shut this corner off for safety reasons. Besides, only lovers with some business like us ever go hear."
