This story begins several years ago. I was 19 years old. It was one of the few weeks my parents actually were out of town. I was very pleased when my sister told me she’d invited her best friend Laura to sleep over that Friday night. Unknown to my sister, Laura and I occasionally messed around. There had been a few times when my sister was in the shower or had run to the store for a short time and Laura and I would immediately start making out, sometimes leading to a bit more than that. We’d never actually had sex, though. The further we’d gone was one time when she went down on me while my sister had stepped out for a minute. That was unfortunately cut short though, leaving me to take care of myself in the bathroom soon thereafter. I was hoping this night would be different. That was why I grabbed the bottle of whiskey, in hopes that my sister (a lightweight when it comes to alcohol) would pass out early and leave us plenty of time to finally do what we’d been leading up to for the past year or so.
My sister went to pick up Laura, and I passed the time by setting up the shot glasses next to the bottle. I was already getting a bit stiff just thinking about the possibilities of the evening. I decided to get a head start myself, and took a few shots before they even got back.
When they walked in, Laura and I gave each other a quick smile, and I knew we were both thinking the same thing. Laura looked amazing. She was fairly tall – about 5’9″ – and thin. She had to bearer length dark hair – almost black – which contrasted her fair skin nicely. She was wearing very form-fitting jeans and a small t-shirt. Her perky breasts – a full B-cup – moved freely beneath the top, clearly unrestrained. They were both chatting up a storm, my sister going on and on about all the gossip she’d heard since they last got together. Laura only seemed halfway interested, shooting me a smile every chance she got, those deep brown eyes sparkling. Laura and I were both steadily taking shots, my sister not keeping up all that well. We both began pressuring her to drink as quickly as we were. She said she knew we could both handle our alcohol a lot better than she could, which was certainly true, but we both wanted her to go to sleep. Of course, we couldn’t tell her that, so we just kept leading by example, taking a shot every five minutes or so.
Before very long, the bottle was empty, and I was definitely feeling the effects. I then remembered the half-full bottle of vodka I’d hidden under my bed and went to retrieve it. I brought it out, taking the long way around the room so I could take a glance at Laura’s nice, round ass. Her jeans had slip down enough for me to see she had on a skimpy little black thong. I felt a stirring in my pants once again. We made pretty quick work of that bottle, too. My sister was definitely fairly drunk at this pointt, but unfortunately, I was now very drunk. The room was beginning to spin a bit, and I knew I had to lie down for a little while. This plan was backfiring. Laura and I shared another glance. She looked very sympathetic, knowing I wasn’t feeling well at all. She looked pretty smoked herself. I knew this opportunity could not be passed up, though, so before I collapsed onto my bed, I set my alarm to wake me up an hour from then. As soon as I hit the pillow, I passed out.
An hour later, my alarm went off. My hand met it with great urgency, silencing it as quickly as I could. It didn’t feel like it had been an hour, more like five minutes. My head was still very clouded, but the spins were gone. I very gingerly got out of bed, hoping it had been enough time for my sister to get to sleep. When I got out into the hall, I was pleased to see that all the lights were off. It seemed I had timed things just right. I made my way back to the living room. I could see by the dim moonlight that the sofa bed had been pulled out, and could just barely make out Laura’s form.
I sat on the edge of the bed and laid my hand on her stomach, which was very flat and tight. I asked if she was still awake in a very soft whisper. She gave the slightest whisper of a response. I leaned in and found her lips, giving her a deep, password kiss. Our tongues danced and she gave a soft moan. We’d both been very patiently waiting for this. I knew we had to be very quiet though. My hand, now on her shoulder, began to slide down her body, first resting on her braless breast for a moment, her nipple very hard now. This was the first time I’d felt her breasts without a bra in the way. I quite enjoyed what I was feeling. I slide my hand down further, once again over her stomach, then down to her waist. Laura’s jeans were now off, and her thong was soft and silky. I ran a finger along her inner tigh, just inches from her crotch. Her hips stirred as I caresed her smooth sexy leg. I could feel the heat from her pussy already.
Her hand then began to search for my crotch. I had on a pair of shorts and had opted to refrain from putting anything on under them. Laura’s hand made its way up the leg of my shorts and immediately found my hardening cock. As she began to stroke and squeeze it ever so gently, I ran my fingers up and down the now damp crotch of her thong. Her legs opened to make it easier to reach. Knowing there was the possibility that we wouldn’t have much time, I grabbed either side of her thong and started to pull it off of her. She lifted her ass and used one hand to help me do so. Her pussy was completely smooth. I ran my fingers up and down her lips, Laura letting out soft moans all the while. When my finger began to tease her clip, her hand squeezed my cock even harder and she let out a deep sight of pleasure. She pulled her hand out of my shorts and went formy fly, unbuttoning it with one quick move. I pulled the zipper down and slide the shorts off a second later. I then climbed onto the bed, my knees on either side of her legs, suspending myself right over top of her.
She grabbed my cock again, much more forcedly this time. As she did so, she bent her knees and lifted her legs out from between mine, then extending them once again on either side of me, wide open and obviously ready. She slide her ass closer to me and, still holding my cock tightly, began to guide it towards her pussy. She teased her clip with the head for a few seconds, then ran it up and down her slit, which was now very wet. As she did so, I gave a little thrust and inserted myself a few inches inside. She let out a louder moan this time, which she immediately realized and clapped her hand over her mouth. She was warm and tight. Her hips rocked again, telling me she wanted me inside her deeper. I thrust myself in further and pulled out a bit again, but not all the way. I could tell this teasing was getting her even more excited. With one more thrust, I slid myself inside the entire way, then positioned my knees so that I was right on top of her.
Again, I began kissing her as I slowly started fucking her hot little pussy. Laura met each thrust with a thrust of her own. My hands moved to her breasts once again, this time lifting her shirt off. As we built up our rhythm, I pinched and teased her nipples, causing them to grow even larger. Her breasts were so soft and full. I knew with all of this stimulation, I wasn’t going to last very long. I leaned in right next to her ear and asked her softly if I should cum inside her. She whispered yes in an almost urgent tone. Knowing I was nearing my climax, I grasped her hips and began fucking her at full speed. It was still very dark, but I could desperately see her pale breasts bouncing with each thrust. Within minutes I was shooting loads of cum inside her, grasping her ass and holding her hips close to me. I was spent, and collapsed onto her body, both of us panting as quietly as we could. We kissed again, and I laid there, still inside her, my cock still twitching, for a few minutes. Slowly I slide out and rolled over next to her. We continued kissing and caressing each other’s bodies, my hand eventually coming to rest on her breast again. Her hand made its way down to my cock again, which was not a very impressive size at this point. She held it for a minute, slowly stroking, apparently attempting to get me going again.
She sat up and leaned in so that I felt her hair brushing against my leg. Her tongue teased the tip of my cock, and then she put her mouth around it, her lips against the base. It took no time till I started growing again. Before long, her head started to rise, as she could no longer manage to keep the whole thing in her mouth. She ran her tongue up and down the shake, stroking with one hand thewhole time. I was sure I wasn’t very far from climaxing again. She then slipped it out of her mouth and positioned herself over top of me. In one quick motion, she enveloped it in her pussy again. Back and forth she rocked, building my erection to its full potential. My hands ran up her body, teasing her nipples and exploring her tight abdomen. In no time, I began to cum again. She let out a whimper as I Felt her cum in unison with me. She collapsed on top of me this time.
We kissed for several more minutes, but I knew we were already pressing our luck. I had no idea how my sister would react if she found us lying here like this, so I slowly got up, slipped my shorts back on, and handed Laura her thong. She slipped it back on and grasped my hand, giving a short squeeze which I knew meant “Thank you.” I leaned in for one more kiss and cares of her breast before I Disappeared back down the hall and into bed. I didn’t know if this would everhappen again, but I was glad we took full advantage of the chance. I passed out once again, very satisfied.
When I awoke, the sun was shining brightly in my eyes. I squited and winced from the inevitable headache I now had. I knew I needed coffee. I walked into the kitchen and started brewing a pot. Then I came out to the living room. I wondered if I was the first one up. I wasn’t getting my hopes up too much, but thought there was a possibility of having a little more fun with Laura before my sister woke up.
She was still in bed, lying on her stomach. Her perfect ass was in plain view. My eyes took it all in, this time in full daylight. The night before I could have sworn her thong was black, but now realized it was really a dark blue. My eyes followed her back and all its curves up to her disheveled hair. Then I went pale. Her hair was not the near-black color it was supposed to be, rather a dirty blonde. The erection that had been growingg suddenly stopped. This was not Laura. I went back down the hall and glanced in my sister’s room and found Laura lying on her bed, fully dressed. Her jeans were still on, and it looked like she’d passed out and not stirred since. The blankets weren’t disturbed at all.
I came back out to the living room, and apparently had made enough noise that my sister was now awake. She squited in the sunlight too. She greeted me and asked how I’d slept. Without even answering her question, I asked why Laura was in her room. She explained that shortly after I’d passed out, Laura started feeling a bit too drunk too and had gotten sick in the bathroom. My sister’s room being the Closest to the bathroom, she had simply walked Laura into her room and had her lie down there. She then took the sofa bed so Laura wouldn’t have to go too far if she got sick again.
She again asked how I slept. I didn’t know how to answer, but saidI guessed I’d slept all right. She said that was the most she’d ever had to drink at one time and didn’t really remember going to sleep. It seemed that was not the only thing she didn’t remember. I didn’t know what more to say. I’d unintentionally fucked my sister and she wasn’t even aware of it. The waves of guilt and worry started to come over me. I knew I would have to keep this a secret. But I also I could not help looking at her perky breasts filling up that tight little t-shirt and that skimpy little thong just barely covering her crotch. To my surprise, she parted her legs slightly as I stared. Then she gave me a huge grin.
“So how was I?” she asked.
