Mystery girl part 2

But then suddenly a voice interrupts us. It was the voice of an older woman. We quickly let go of each other, her pulling her top back on and me closing my belt.
I think I managed fine. Except for my dishevelled hair and my red face, there was nothing hinting to what just happened. What I didn't manage to hide was a visible expression of frustration, but who can blame me for it?
The girl looked a lot less innocent. Her hair messy, face red and lips still glistening from our kiss. She just pulled the top down over her jeans when the woman appeared around the corner. The girl had her face turned to the women, from the back it was easily visible her bra was still open, but from up close I could still see the open wings of her waistband protruding, forming a slight hill near the rim of her top.
The woman was holding a phone up to her ear, giving the girl a quick smile as she looked to the floor, walking past us.
The girl just smiled back. I laughed as I followed the woman's glance to the packed condom that had fallen to the floor.
I picked it up and put it in my pocket.
The girl turned to me and blushed. I hugged her, sliding my hands under her top as I did to close her bra. Then I slid my hands down to her hips and pulled her in for a kiss. I drove my hands down the front of her pants, feeling the damp spot on her slip before she could break the kiss.
I pulled my finger back out before she said something and laid it on her lips to silence her, before turning away and leaving.

I wouldn't see her for a few weeks. Long weeks for me as she never left my mind even once, my desire for her only growing. I found no relief whatsoever and was starting to get frustrated. A few of my friends decided to hang out at the beach and invited me to join. **** at first, I eventually gave in.
We took my car, actually. It has enough store room to hold us four and our beach stuff in the boot, and when we pulled up at the small cliff side that marked the coast, we were quick to unload everything. The car was parked right next to the trail that leads down to the small sand patch, in a sort of 'micro-bay'. There were a few bikes parked at the end of the trail and we spotted the owners laying on their towels as we headed towards the water. We put our stuff down at a place where boulders obscured the view on the strangers as well as the trail back. Surrounded by stone, we changed into our bathing suits. Amy had simply worn her red bathing suit underneath her shorts and blouse. The rest of us had no problem changing in front of each other.
I was the first to dive head-first into the water, quickly joined by Amy and the other boys.
While they splashed around, I spotted a figure swimming in the water about a hundred yards out. Somehow this got my attention to such a degree that I excused myself and got out of the water, climbing onto a boulder to look where the figure went.
I saw it leave the water right where the sandy patch ends and merges into a small cave entrance. It was a girl, clearly. She entered the cave and I lost track of her.
I climbed down the boulder and walked across the burning sand towards the cave, passing the older couple laying in the sand.
Although a little shadowy, the cave was still well lit enough to see clearly, the water reflecting the sunlight onto the cave's ceiling, dipping it into a sort of blueish light.
I cleared my throat, to announce my presence. A pair of legs that protruded from a crack in the wall of rock left the ground and a girl jumped out of a sort of natural bunk of stone. I knew this girl, her hair was still wet and drops of water fell to the ground as she stepped out of the shadows. It was then that I knew for sure that I knew her.
She came towards me, opening her mouth. I suppose she wanted to introduce herself, but I didn't let her. Instead, I grabbed her by the neck and kissed her. In the beginning, she was hesitant again, and it almost felt like she wanted to push me away for a second, but then wrapped her arms around my back.
We made out for what felt like an hour before she made the next move, running her hands down my back, towards the brim of my swim shorts. She opened her eyes and looked at me while slowly pulling them down. She grinned when they finally dropped to the ground. I pulled off my beach top and stood naked in front of her. But when I made a move to remove her bikini top, she stopped me and smirked. She kissed me again and pressed herself against me, rubbing her bikini bottom against my groin. It was driving me crazy, so I eventually pushed her off me and against the crack in the wall she climbed out in the first place, forcing her to sit on the cold rock. I felt the goosebumps on her legs as I slid my hands across her thighs. My fingers rested on her waist with my thumb lay on her bikini covered mound, caressing it through the wet fabric. With one arm, I slid back down to her ankle, lifting it to my lips and planting a kiss on it. I made my way up her calf and thigh, planting a kiss every other inch until I planted my last kiss on the cloth of her bikini. It was still salty from the ocean water, but I didn't care. My plan was to get rid of it anyway. I undid the ties at her hips and let the fabric fall down by itself.
I laid another kiss on her mound. This time connection to her skin. I moved my lips down a little and laid another kiss on her, feeling the stubble of her body hair, tasting the ocean's salt on her skin.
My next kiss reached the soft flesh of her clitoral hood. My tongue started to move on its own, extending downwards, tasting the sweet folds of hers. She shivered and gasped when my tongue curled up and brushed her most sensitive spot. I nearly moaned in excitement myself but then shouts echoed through the cave. The girl quickly pushed me off her and had me stumbling backwards, resulting in me falling into the water that filled the cave. She shoved my clothes into the water with her food and wrapped a towel around her waist before Amy appeared at the cave's entrance. My friends have been worried about me and come to look where I've disappeared to.
When I briefly explained how I met this girl, Amy took a hint and left. But not without winking and smirking at me first.
The girl sat down at the edge of this little 'cave bay' and let her legs down into the water. She put her towel next to herself and gestured me to come closer. I swam over and slid between her thighs, resting my arms on them. I looked into her eyes.
