Knocking on my door woke me up the next morning. My room was bright. I had slept long after sun up. Looking at my arms I could see the dried latex and if the person knocking came in I'd have some explaining to do. Ripping it off as fast as I could, I answered the door.
"He is alive, Mr. Sleepy Head!" Lisa said standing in the hall.
"Yeah, Yeah," I replied to her mocking.
"Mom and I are going to the mall; you're welcome to join us."
"No thanks, following you two around for hours doesn't sound fun."
"You're loss. See ya later."
After they left I was alone in the house. I got some food, showered and went up to Lisa's room. I was going to find her stash of patches and condoms, maybe see what else she had. They weren't easy to find, she had pulled out her dresser drawer and hidden them on the floor under the drawer. It was clever but I knew that trick, it's where I used to hide my porn, before I got a computer. I took a patch and one condom. She wouldn't miss either, since she had a boat load.
I started my daily summer chores, feeling a little run down from last night but I managed mowing the lawn and my other stuff. I was watching the video where I left off when Mom and Lisa got back home. Lisa had definitely fucked my cock with her ass. The second time it took me a long time to cum catatonic and she rode me for over an hour according to the time on the screen. She just didn't keep my cock in her ass the whole time; she let me out only to slide down on me into her pussy for a few minutes before going back to her ass. I really wished she would have done that last night and you never know she may tonight when Mom and she come back to my room.
I was playing with myself, enjoying the way my sister enjoyed screwing me and watching her cum but was unable to get myself off because they came home. Putting my cock away I turned off the video and left my room.
"Oh, good," Mom said when I came downstairs. "I was just telling your sister I have to leave again. I'm meeting your father for his company party. You two are on your own tonight."
"I'm sure we'll manage," Lisa said. "I'm exhausted from all the walking; I'm going to take a nap."
I watched her head upstairs, knowing she was exhausted from lack of sleep not the mall. Mom left soon after and I went to my room to finish tossing off. As I got started I remembered the patch I had stolen from Lisa and the condom. The idea for a little payback followed. I took both, put them in my short's pocket and crept to Lisa's room, listening at the door to see if she was asleep or not. Braving it, I twisted the doorknob and quietly went into her room. She was balled up on her bed, breathing deeply, apparently out cold.
Moving slowly toward her I took the patch out of my pocket, pulled the adhesive cover off and gently placed it on my sister's upper arm. I looked at my watch, timing ten minutes like on the video, to wait before seeing if she was unconscious or not. It seemed like time crawled, my cock was rock hard with anticipation. I couldn't wait to fuck my sister and actually be able to touch her like I wanted last night.
Finally, I moved forward and shook her, "Lisa! Lisa, are you awake? Lisa!" I shouted. Nothing, the patch had knocked her out just like me.
Rolling her on the bed to her back I began to unzip her shorts and tug them off her body, pulling her panties down slightly so I could see the top of her shaved slit. My heart was pounding again and I made quick work of her underwear, dropping them on the floor and admired the view. Big sister had a very pretty little pussy, perfectly formed and shaved to perfection. I spread her legs, and went head first into her sex. My tongue spread her open easily and I tasted her wetness and savored my sister's essence. My hands crawled up under her T-shirt, finding her bra covered tits. Going under the bra I quickly found her nipples hardened even when she was drugged, as did her clitoris as I licked it.
Just like me her body reacted to the sensations I was causing. She felt and tasted wonderful to me, her breasts were firm and her nipples were perfect to play with. I stopped playing and finished undressing her completely, before taking my own clothes off. My cock was raging and oozing big time so I put the condom on to keep the evidence from getting all over her bed. Once I was covered up I went back to eating her and decided to finger her little ass since she liked to take my cock there like Mom. Before long, though I was too horny and needed to use my cock.
Pulling my big sister's legs up I held her ankles with my left hand and bent my cock down to ease it into her very wet pussy. I knew it wasn't just my saliva that had made her so wet. Somehow the patch allowed the body to be stimulated and respond accordingly. She was so hot and wet, smothering my cock in heaven. I let out a long moan as I slid each inch in slowly until my balls were up against her ass. Big sister's pussy was oh so nice.
"Pay back feel's good, Sis. Really good," I said to her closed eyes.
Leaning over I began sucking her tits, pulling on her nipples with my mouth and thrusting gently over and over. The excitement of what I was doing was off the charts. My heart pounded in my chest and I had the rush of adrenalin in my head making things slightly fuzzy. I feasted on her wonderful breasts and just kept the same steady in and out thrusting of my cock for a long time. There was no rush, it was early evening and I had plenty of time to enjoy my big sister.
Her room began to get dark from the sun setting and before I realized it I couldn't see much anymore. Pulling out I turned her light on and flipped her over onto her stomach. I tried to get her ass of the bed more and ended up putting a pillow under her because she would just fall flat on her own.
I wanted to fuck her ass badly, and feel what it was like. Mom's was so tight and hot, I was sure Lisa's was going to be even better. Problem was I didn't have the lube they used. It wasn't hidden with Lisa's patch and condom stash. Mom probably had it unless it was something I didn't realize. I didn't pay attention watching the video to see what Lisa used. Once she was in position, I tried saliva and her own juices to lube her up but there wasn't enough and it dried out too quickly. I did notice a lot of pre-cum in the condom from the time spent slowly fucking her pussy. Taking the condom off, I began to squeeze my juice out of the condom onto Lisa's tight ass. There was a lot and it was very slippery, perfect for ass fucking.
My fingers penetrated her easily and then I moved my uncovered cock into place. Slowly pressing in, my head disappeared into my sister's ass and it was glorious, tight and hot, just like I knew it would be. Slowly moving forward, I buried my cock into her up to my balls. Without the condom on it felt even better, my flesh wrapped completely snug with my sister's ass flesh. I basked in the sensations it caused, loving her tight fit and the image of my cock sliding smoothly in and out.
"Damn, Lisa, your ass is fine! Even better than Mom's."
After the time I spent fucking her pussy and now her tight ass I was soon ready to drop my load, but since I didn't have the condom on anymore I couldn't exactly cum in Lisa's butt. She'd know something was up for sure when she woke up. Slowing my thrusts, I tried to enjoy the sensations just a little longer. It felt so good, my big sister's body was a wonderland of delight and I was doing things I had only dreamed about doing before that evening.
Her ass seemed to hug my cock perfectly, especially the tight ring at the entrance. I could feel it latching on to my shaft as I slid in and out. Reaching under her I got more breast time in and even shoved some fingers in her very wet pussy while I fucked her ass slow and deliberate. Heaven was right there in my big sisters room and I was taking full advantage.
Soon the pleasure was just too much and I had to cum. Pulling out I shot my load onto her back, making sure to keep the ropes of cum centered so they wouldn't run off onto her bed. The excitement and thrill produced more than I thought after being so used lately and by the time I finished, I had several stripes and a good sized puddle on Lisa's sexy tan back.
Now I had to clean up and hide the evidence.
It took some time but I toweled her off, got her dressed and back in her original sleeping position before taking the patch off and leaving her room. I figured I'd wake her up in a half hour once the drug had worn off. All the work was worth it.

"Lisa? Lisa, are you planning on sleeping in your clothes all night?" I asked, waking her up.
"Huh? Wow what time is it?" she asked.
"Ten, now who's the sleepy head?" I asked.
"Wow, I really crashed," she said sitting up.
She adjusted her bra and shirt but didn't say anything about it. I figured she assumed sleeping had done it to her.
"Did you have plans tonight?" I asked.
"Sort of, not set plans I was supposed to call Lacy if I wanted to get together. I guess I'm not doing that. It's really ten? I might as well just go back to sleep," she said laying back down.
"Whatever you want to do," I said, leaving her room.
She had no fucking clue! Who had the upper hand now, Sis?
*****
Mom and Dad got home late and Dad was overly touchy with Mom so I assumed she wouldn't be in to visit me and if Lisa never got up I might have the night off. I was watching a zombie movie on the big screen and didn't go up to bed until 2 A.M. I put the latex on my arms just in case but fell asleep anyway. I figured when they shook me awake, to test the patch, I would hopefully not freak out and ruin the fun I was having. But I wasn't expecting anyone tonight.
All of a sudden I heard voices in my room, waking me up before they shook me.
"Are you sure this is going to work?" a voice whispered.
I didn't recognize it, but I did recognize Lisa respond, "Yes, Lacy, I've been doing it all summer."
