"Kyle!" My sister, Kelly, called to me from her room.
I was down in the kitchen, rummaging through the cabinets looking for something to have for breakfast. Kelly and I were both home from college for the holiday break. I was a graduate student and Kelly was a sophomore, being three years younger than me. Mom and Dad had left early this morning to drive up to Oklahoma City to go Christmas shopping and they told us they'd be gone all day -- so, Kelly and I were left to fend for ourselves until sometime late this evening when Mom and Dad returned.
"In the kitchen!" I yelled back to her. "You want some breakfast?"
"I'm right here," I heard her say, standing right behind me. "You don't have to yell."
I turned to see Kelly standing behind me in one of her short sleep shirts. It was barely long enough to hide her panties from my searching eyes. Her nipples were poking out from under her shirt and I could easily see the bulk of her breasts straining against the thin t-shirt material. I tried very hard not to stare at her, since I definitely didn't want her to get self-conscious and go back to her bedroom and put something else on. Besides, I didn't need to stare - I'd seen her naked enough times to know exactly what she looked like underneath the shirt.
Kelly and I made small talk as we had a breakfast of cold cereal and juice. Once she was finished eating, Kelly asked, "Can you come up to my room for a few minutes? I've got something to talk to you about."
Figuring she wanted to talk about Christmas presents for Mom and Dad, I told her I'd be up in a few minutes. The last few years, Kelly and I combined our meager earnings to get Mom and Dad a present from the both of us, and I was sure she wanted to see about doing the same thing this year. So, after I cleaned up our dishes and put them in the dishwasher, I went up to Kelly's room.
She was still in her sleep shirt, brushing her hair, as I stopped in her door way and looked in. With every stroke of her brush, I could see her breasts jiggle and the tips of her nipples graze against her shirt. Kelly was an amazingly beautiful girl, completely unaware how stunning she was, or how her tight, lithe body affected me. She seemed to blossom into womanhood almost overnight when she was a senior in high school. One day she was my scrawny, knobby kneed little sister, and the next moment, she was an eighteen year old knock out, and she didn't even know it.
Looking at her, I felt a little guilty about fantasizing and thinking about by own little sister in a sexual way, but, it was really her own fault. She wore the skimpiest outfits around me, and it was unbelievably easy to catch her dressing and undressing behind her almost closed door. She was completely oblivious to the incredible shows she'd been giving me for the last three years, and I'd even stroked myself numerous times standing out in the hallway outside her door after Mom and Dad had gone to bed, watching her undress -- even seeing her touch herself one night after a late night shower. Kelly was a walking fantasy for me and the primary reason I came home to visit as much as I did. If I knew Kelly was going to be home, I'd be there, too.
One thing I really loved about Kelly was that she was incredibly carelessness with her panties. She'd leave them in the bathroom or in plain sight on the floor of her bed room, just begging me to inspect and examine them closely. It was never hard for me to get a pair of her warm, moist panties -- and if I timed it right, I could usually have them in my hands within ten or fifteen minutes of the time she took them off. Believe me, they were something to behold, and I enjoyed them immensely. I would simply hide them in the big laundry basket in the laundry room when I was done with them, Mom would wash them up and no one would know. I'd done it probably a hundred times.
Although Kelly and I go to different schools, and I only see her at home for holidays and school breaks, she was still my faithful eye candy and I measured every girl's beauty against hers. She was truly an alluring and sexy girl, and she quickly became the center of all my fantasies and masturbation sessions.
When Kelly saw me standing in her doorway, she pointed to her bed and asked me to come in. As I sat down she asked, "Do you know what the term 'Quid Pro Quo' means?"
"Sure." I answered. "It means if you do something for me, I'll do something for you."
"Exactly!" Kelly exclaimed, followed by, "And I'm glad you defined it in those terms because I think there's a little Quid Pro Quo you owe me. Since Mom and Dad are going to be gone until late, I thought today would be a good time to collect."
"I'm not following you." I replied.
"Kyle," she explained, "whether you believe it or not, I'm not blind or stupid. I know you've been peeking at me and stealing my panties for at least a couple of years. I've never said anything or tried to stop you. But, it's time for you to pay me back."
It took me a few seconds to comprehend what she said, and I knew it was time to make my exit to the safety of my own room. When I started to get up from her bed, she took a few steps and stood in front of me. "Not so fast, big brother." She warned, with a serious look in her eyes.
"You're going to hear me out." Kelly advised. "I've let you watch me in the bathroom when I take a shower or a bath. I leave my bedroom door cracked open so you can peek in and watch me get dressed and undressed. I've left my panties where you could find them and given you ample opportunities to see me naked."
"Kyle," she continued, with her hand on her hips, "I even shaved my pussy, and kept it shaved so you could see it better. I've let you watch me play with myself and I always gave you enough time to make yourself cum when you were peeking at me."
"You must be out of your mind, Kelly." I argued as I tried to get by her and out the door.
"I hope you're not trying to deny any of this," Kelly answered sternly, "because if you are, you're going to regret it."
"Kelly...." I said, about to try to defend myself. But she stopped me and told me to let her finish.
"Look, Kyle," Kelly said sympathetically, "I don't want you to think I'm mad, because I'm not. I know you've been doing this for a while, and honestly, I could have stopped it any time if I'd wanted to. The truth is, I let it go on because I enjoyed teasing you and making you hot for me. But, it's time for you to pay me back, and if you don't, I promise you'll never see me naked again and you'll never get another pair of my panties as long as I live. I mean that, Kyle.... I'm not kidding."
One thing about Kelly, she knew how to express herself, and the words she'd chosen to chew me out left no question in my mind where we stood. I was busted and she wanted some thing in return.
"So," she continued, "today, you're either going to start paying me back, or it's all over." Kelly said, crossing her arms over her chest, cradling her breasts in front of me. "Today, you're going to even the score and we're going to get this out in the open, or.... you've sniffed your last panty, big brother."
Seeing I had no choice other than to capitulate, I simply said, "Okay, fine."
"Good." She replied. "And, I expect you to cooperate fully. You can start by taking off your clothes - all of them...... and I mean right now."
Kelly took a few steps back and shrugged her shoulders at me. "Go ahead." She said calmly. "Start undressing. I want to see you naked."
I was stunned and shocked at what she asked me to do, but, fearing what would happen if I didn't start taking my clothes off, I grabbed the bottom hem of my shirt and I pulled it over my head. When my shirt was off, Kelly held her hand out and asked me to give it to her. "Hmm," she moaned in satisfaction, "I can't wait to see you naked, Kyle. You don't know how long I've waited for this."
"Here," she said, reaching out to grab my wrist and pull me out to the center of her room, "stand here so I can sit on the bed and watch you strip." Giggling, Kelly moved back to the bed and sat down, crossing her legs indian style. Unconsciously, I glanced between her legs hoping to see her panty covered crotch, and when she saw me looking, she smiled and pulled her sleep shirt up to her waist. "Can you see now?" Kelly asked as she smiled up at me. "Go ahead..... I don't mind if you look. In fact, I want you to look. I bet you recognize these panties, don't you?"
It was true. I'd seen those panties many times. Most recently, I saw them the night I arrived home from school, just five days ago. Kelly was already home, having arrived a few hours ahead of me. As soon as I walked in the door that night, I had to pee after my long drive. So, after hugging my Mom and shaking Dad's hand, I ran up the stairs to the hall bathroom and found those exact same light blue panties lying on the floor next to the bath tub. I looked down at them while I peed, and I remember smiling to myself -- thinking what a nice home coming present my sister left me. Without thinking, I picked them up and looked inside at the crotch panel for the signs of Kelly's natural wetness. Sure enough, there was a small spot of clear, slick pussy juice -- still wet and fresh from Kelly's pussy. Chuckling to myself, I stuffed them in my pocket not even the slightest bit concerned that Kelly might miss them. After all, I'd taken her panties so many times and got away with it each time, I didn't even consider the fact that she might find them gone.
"Jeans next." Kelly said, smiling at me and pointing to my pants.
"I'm sure you didn't realize it," she giggled, "but, I was wearing these panties when I heard you come through the front door the other night. You know, it only took me about thirty seconds to take them off and toss them in the bathroom. No more than two minutes later, you went in there. Funny thing, though," Kelly added, "I looked in there after you left the bathroom and guess what? My panties were gone. These exact same ones, Kyle, the ones I'm wearing now. Surely you remember?"
Kelly had a shit-eating grin on her face. That night, I'd kept her panties in my pocket until I went to bed. Then, in the seclusion of my own room, I pulled them out and laid her silky panties across my face and jacked my cock. Even as I stood there in front of my sister, about to unfasten my jeans and step out of them, I could still remember how good her panties smelled. And, I was starting to get hard recalling the way I sniffed and licked her panties while I jerked myself that night.
Snapping me back to reality, I heard Kelly say, "Just to prove that I'm a fair person, I'll take my shirt off so you can see my boobs after you take your jeans off. Then after you take your underwear off, I'll take mine off, too. You'd like that wouldn't you, Kyle?"
I nodded my head up and down as my hands unfastened my jeans and pulled the zipper down. Kelly, seeing that I was about to take my pants off, adjusted the way she was sitting so that she was half laying down on her side with one of her knees bent way up. Again, she pulled her night shirt up, this time almost to the bottom of her breasts and then she lewdly thrust her pelvis out at me.
"Come on, Kyle!" She hissed. "Hurry up. Can't you see I'm waiting to see what you've got in there? Do you have a hard-on now?"
