Let me start by saying that this is a true story and that only a few names have been changed. You never know who might be reading sex stories on watchers web!!

I was engaged to a gorgeous girl for about 3 years. We had dated for almost 3 years before getting engaged also, so we spent almost 6 years together in total. During that time we came to know each others family very well. Kara had 2 sisters, one was a couple years older and the other a couple years younger. Her oldest sister, Lea, was away at school for quite a while and was not around much. Lucy was her younger sister, and she was still in high school when Kara and I began dating. All three girls are gorgeous, my fiance was brunette with bright green eyes, a slender nose and perfect smile. She was an athlete and had an incredible body also, slim but with perky 34C tits and a fantastic heart shaped ass. I considered myself a lucky guy, I had definitely out kicked my coverage on her. Her sister Lucy was also a beautiful girl, but was totally the opposite of Kara. Lucy was tall and blonde with brown eyes. Her face was more round, but she had the same perfect smile. The biggest difference was her body though. She was almost as tall as me (5'9") and was much thicker than Kara. She had big tits that were still perky, and a big round ass. She wasn't fat at all, but she definitely had a few extra pounds in the right places. Both girls similar bubbly personalities and my god did they like to flirt, which of course is where it all starts...

Like I said above, when I started dating Kara her little sister was in high school. After around a year and a half, Kara moved out of her parents which was about 20 minutes from town and moved into my place downtown. Because of the close proximity to everything and because she hated her parents (like every teenager does), Lucy was at my place all the time after school. I worked a lot of overnight shifts, so Lucy stayed with Kara quite often at the apartment. Her parents trusted Kara and I, and so our place had basically become Lucy's second home. Needless to say, I got to know Lucy pretty well.

About halfway through her senior year Lucy turned 18, and almost immediately I saw a change in her. She had always been flirty, but it was harmless stuff and I chalked it up to her being a young and dumb girl. But after becoming "legal" Lucy began to push things a little further, so much so that even Kara noticed. Prior to this point Kara had just laughed it off and thought like I did, dumb kid. On top of becoming more flirty and open about sexual stuff, Lucy had developed into an incredibly sexy young woman. She knew it, I knew it, everyone knew it. She loved dressing in next to nothing in public, and it only got worse when she was in the privacy of MY apartment. Both Kara and Lucy would walk around the apartment in just their bras and panties unless we bad company, which was rare. It was all but normal for Lucy to sit beside me on the couch in a thong and one of my shirts, most likely no bra underneath either. On one of the more memorable occasions, Lu walked out of my bathroom with only a towel on. Now normally a bath towel covers as well or better than what a lot of girls wear in public, but this was not a normal towel. This was an Army issued towel, not much bigger than a hand towel. Anyways, Lucy walks out of the bathroom in the smallest towel I own and has to walk across the living room where I'm sitting. Of course I about shit, and as if her entire ass hanging out isn't enough, she drops her dirty clothes right in front of me. Without a second thought she bent over and picked up what she dropped. I got a perfect 2 second view of her 18 year old pussy and it was incredible.

These types of things went on for months until I had had enough.

I was on vacation from work and had taken a week to just relax at my place. Kara worked all day and so I had the place to my self. This was in June and Lucy had just graduated from high school and she was partying with her friends every night. She had been showing up drunk and crashing at our place all week, but she was usually gone when I got out of bed.

That Wednesday when I got out of bed I could hear my shower running. We had a small on-suite bathroom in the master bedroom but I was the only person who used it. Kara hated how small it was. I sat up a bit confused, but I figured Kara was running late and just jumped in my shower. I laid back down and waited to see what was going on, figuring it would be Kara that walked out.

The water turned off and I heard the shower door open, then I heard a bit of a stumble and the door popped open. My room was dark because of the black out curtains on the window so when the door opened I was treated with quite a sight. Standing there completely naked was Lucy. Her front half was shadowed just enough to obscure her features but I could see the swell of her perfect tits and the curve of her hips. She took a few steps into the room and sat down clumsily on the end of my bed and laid back. Her head was about level with my knees and I had a clear view of her body now. Her nipples were about the size of a nickel and an incredible red color. Her body was smooth and evenly tanned and there wasn't a hair to be found ANYWHERE. I asked her what she was doing and why she was in my shower and now my bed. With her answer came some slurring and she was obviously still drunk. I asked her to get up but she didnt budge. She told me she needed help getting dressed and laughed at my obvious discomfort. I didn't know what to do, but my hormones were starting to take over. I got up and walked to the end of the bed and stood between her spread legs, my erection was straining at my boxer briefs. I tried to help her stand up, but she just went dead weight and laughed at my effort. She was making comments about the tent in my shorts. She may have been drunk, but she knew exactly what she was doing too.

I gave up doing the right thing and said fuck it. I knelt down between her legs and with no other second thoughts I put my mouth over her smooth little pussy. Lucy let out a gasp and feebly tried to close her legs but I was to far gone at that point to turn back. I pushed her legs up and opened them wider while I sucked and licked her incredible cunt. She was literally dripping wet and she tasted like strawberries. As I flicked my tongue over her clit, she made the cutest little moans and gasps. As I ate her pussy I worked one finger into her hole, it was impossibly tight. I licked and sucked her clit while I finger fucked her to a massive orgasm. I'm sure the entire block heard her screams of ectasy. She was so sensitive that she pushed my head away, not able to take anymore. I reluctantly pulled away and moved up her body leaving a trail of pussy juice and saliva from her mound to her enormous tits. Her nipples were diamond hard, and as I sucked one into my mouth, Lu's entire body shuttered in pleasure. I began licking and gently biting both nipples, while her hands roamed my body.

She pulled me up and attacked my mouth with hers, her teeth even hitting mine hard enough to hurt. She didn't even flinch though, our tongues wrestled between our mouthes in a sloppy but insanely hot kiss. She pushed my briefs down as we made out and finally released my rock hard dick. As we kissed she began awkwardly jerk me off, you could tell she didn't have much experience, but the taboo nature of the situation had me extremely turned on. Her rough hand job felt amazing! Nothing had been said between us to this point, but I was ready to fuck and I wanted her to vocalize that she wanted it. She practically pleaded to me, and I am a softy for a begging girl. I gathered spit and coated the head of my cock liberally, but I didn't need it. Her cunt was by far the wettest I'd ever felt. I pushed her legs up and lined the tip of my dick up with her slit.

As I pushed in, Lucy's expression was that of pure pleasure. I moved into her, slowly, inch by inch. Her pussy was impossibly tight, and As I would find out after, barely used! I pushed into her until my pelvis met hers, and my balls rested on her tight asshole. I paused for just a second to let her get used to the size and then without mercy I pulled out and slammed back into her. She yelped in pain, but nodded her pretty little head for me to do it again. I started to pump into her, long, hard strokes. Each time slamming her hard enough to make a loud, wet slapping noise my neighbors would have heard. Lucy was begging me to fuck her hard now, so I did. I slammed my dick into her greedy little cunt hole as hard and as fast as I could. After only a few minutes I could feel the come building up in my balls. Just as I was about to blast, Lucy's whole body clenched up. Her legs wrapped around me and her pussy gripped my cock almost painfully hard. As I unloaded into her, I could feel intense pressure pushing out. Her pussy gushed out liquid, forcing my dick out while she squirted stream after stream. I sat back in amazement as her pussy slowed to a dribble, both my and her cum ran down her legs and ass onto the bed. My entire lower half was soaked. Lucy laid there in a daze, barely able to speak or move but with the sexiest grin I've ever seen. I looked over her body, and nothing I've seen since that moment compares...my 18 year old little sister in law covered in cum and sweat, her hair splayed across my pillow, and her hand playing with our cum that was leaking out of her cunt.

"Finally"...
