She stood up and made her way to the sun lounger, as I rolled over onto my front to hide my cock.
"One other thing." she said, "Tell anyone about this and I'll murder you in your sleep, got it?"
"Yes, absolutely." I replied. Who the hell would believe me if I did? I thought.
"Tell anybody about what?" asked mum as she walked around the corner of the house with a plate and a glass for Carolyn.
"About me borrowing this skirt off Sarah." Said Carolyn, quick as a flash.
"It's not that big a deal, surely" stated mum, completely oblivious to what Carolyn had really been talking about.
Mum sat in one of the chairs, which left me lying on the floor with Carolyn to one side and mum to the other.
"You should get changed and get some sun on you." mum said.
"Naaah, I'm OK." Said Carolyn.
"Go on! Where's that nice bikini you begged me to buy for you weeks ago? I've never seen you wear it once!" said mum.
"OK, OK, I'll go and get changed once I've finished this." I heard from my other side.
I was still on my front, with my head resting sideways on my folded arms. I was looking at Carolyn as she sat on the edge of the lounger facing me. More specifically, I was looking at her knees, which were held tightly together as she rested her plate on them.
I was willing them to open, but nothing. Is she really going to purposely let me see her panties? I wondered to myself. How is it going to happen? How often?
She kept glancing down at me every now and then as she ate but said nothing.
When she had finished, she took hold of the plate and then looked over towards mum. Her knees slowly opened, just for a second or two, then she stood up.
It was just a flash, but I was sure she had meant to do it.
She looked down at me with a little smirk on her face as she walked past me.
"And don't even think about stealing my place." She said, as she headed inside.
After about ten minutes, she came back outside, barefoot, wearing an oversized tee shirt. She raised the back of the lounger so she could sit back, slightly reclined and lay down.
I turned my head and watched her again, waiting for her next move in this exciting game we had started to play.
After five minutes or so, she sat up and removed the tee shirt.
The bikini was tiny! It was white, with strings that tied around her back, around her neck and on the side of her hips. As she lay back down, the bikini bottom, which sat really low on her, stretched across her hip bones, leaving a gap between the skin of her lower abdomen and the edge of the bikini of almost an inch.
After a couple of minutes, she sat up and, taking a bottle of sunscreen that was at her side, poured some into her hands and rubbed them together. She stretched forward and covered her legs in the oily liquid, glancing in my direction for a second, as she did. Once she had done her legs, she lay back and squirted a big pool of oil on to her stomach. Quickly putting the tube back down by her side, she scooped up the oil with her hands and began to rub the lotion into her skin. I watched, fascinated, as she started with her arms, shoulders, face and neck.
As she moved on to the tops of her breasts, I felt my cock begin to stir again. Next, she stroked her way across her belly, slowly working her way down to the edge of the bikini bottoms. I could feel my cock hardening even more.
When her fingertips reached the edge of the bikini bottoms, she slid them under, inside her bikini, just for a second. Her fingers disappeared past her second knuckle and I could see the outline of her fingers moving under the material. She seemed to push them all the way in, then paused, just for a split second, before pulling them back out. She brought her hand up to her face and inspected her fingertips before continuing and rubbing her belly for a couple more seconds.
I noticed that the outline of her nipples had become very visible, and they were pushing against her bikini top. It took me a while to realise what she had just done, but it was obvious to anyone (which was only me) watching. She had just given her pussy a quick rub.
I must have seen my sister applying sunscreen to herself a hundred times, hell, I'd even done her back for her a few times. But now it had transformed into some seductive, sexual ritual.
Nothing else happened for the next couple of hours. We all just lay in the sun. I was, however, a bit disappointed when mum offered to oil Carolyn's back for her after she had turned over. It caught me completely by surprise and I'd been imagining getting the chance to do it myself.
The rest of the afternoon was pretty uneventful and after I'd had enough sun, I went back inside leaving Carolyn and mum chatting away. I didn't see much of Carolyn until later in the evening.
I took an early bath and got changed into PJs. In my new-found state of sexual self-awareness, I decided not to wear any underwear. As soon as I pulled up the PJ bottoms, I felt so much more, horny. The feel of my cock freely swinging around and the added danger of the possibility of my cock slipping out of the fly at the front just heightened the sensation.
Later on, I was laying on the sofa watching TV with dad. Carolyn came into the room, dressed as if she was going out somewhere. She had a black silky shirt on, with quite a few buttons undone, and a wine coloured, knee length, pleated skirt.
As soon as she walked in, I began imagining what she was wearing underneath. Had I held the panties and bra in my hands when I was exploring her 'special collection?' Was it the wine-coloured set to match the skirt?
Her legs were encased in sheer black nylon and I wondered if they were stockings or tights. Her painted toenails poked out of the 3-inch heeled, strappy shoes she had chosen.
"I'm off to the Fleece (a local pub) with Sharon." She announced.
Sharon was probably the wildest of her best friends, whom I'd had a bit of a schoolboy crush on over the years. She was blonde, about the same height as Carolyn, but was a bit more, curvy, and, she had (in my opinion at the time) huge breasts.
I suddenly found myself thinking about what underwear Sharon wore. Did she have a special collection? What did those huge tits look like in a lacy, transparent bra?
"OK, don't be late." Said dad without looking up from the TV.
"I will." Joked Carolyn. "Bye!"
As she walked past me, she leaned over and bringing her head close to mine said "See you later Alligator." The act of leaning over caused her blouse to fall away from her body, giving me an unobstructed view of her breasts, cupped in the tiny wine-coloured bra I had been looking at earlier. I had been correct. The low-cut style of the bra barely covered her nipples. I could clearly see the top half of her areola and could just about see her nipples pushing against the lace at the edge of the cups.
I only saw this for a second, but it was long enough to give me an instant hard-on. I had to sit up and stop it escaping out the front of my PJs as she left the room.
Carolyn got back at about 10.30 as we were all watching the TV, she seemed a bit tipsy, but not overly drunk.
Both chairs and sofa (I was laid across the entire length of it by then) were occupied, and rather than asking (or telling) me to move up, after removing her shoes she sat on the floor with her back to the wall, next to the fireplace.
In this position she was directly facing me on the sofa, with mum in her chair on her right, and dad in his to the left.
She chatted a bit with mum and dad about the events of her evening. I wasn't paying much attention until she mentioned they had been talking to a couple of cute guys.
I glanced over to her and my attention was immediately drawn to her skirt. She was sat with her feet flat on the floor about a foot and a half apart. Her knees were together, drawn up towards her chest. The front of her skirt was resting on top of her knees, the back of it was on the floor by her feet.
Now, all dad and mum saw, was the skirt side on, which from their angle covered the entirety of her legs. However, I was staring at a gap between her feet, through which I could see the backs of her thighs. Her stocking covered thighs! I could see black suspender straps to the outside of her hamstrings, and I was mesmerised by the stark contrast between the black of the stocking tops and suspender straps, and the pale flesh of Carolyn's skin.
Unlike all the other occasions I had seen her panties over the past couple of days, this was so much more seductive, and it wasn't over in a flash. As she chatted away, I studied in great detail what was on display. I let that sink in. What my sister was displaying, for me.
I had to grab a cushion to cover my erection before I could then take my time, as I studied the tiny patch of wine-coloured panties in between her legs. It had been compressed into a thin strip and hung quite loosely in front of her pussy. I could clearly see hairs poking out from either side, and I could just make out little strips of loose, wrinkly skin on either side of the material.
