Carol bent to retrieve a present under the tree, her loose nightgown fell away from her chest letting me see for the first time her large areolas and nipples. Her nipples were hard and her large breast hung down loosely. I had wanted to see those breasts for years and here they were on full display. I continued to watch catching more and more glimpses of her large breast as she continued to pull more gifts from beneath the tree. Her areolas were light pink and quite large, her areolas were large but not well defined, near her nipples the pink shade was a little darker but got lighter the further away from her nipples you got until they just seemed to fade away into the rest of her breast. As Carol moved, her breast swung freely and I hated to see her pull the last gift from beneath the tree. Carols gifts were spread out on the floor in front of me and she sat down Indian style with her legs crossed as she began to unwrap her first gift. Carols gown had pulled up and I could see her panties, specifically her crotch, as she continued to unwrap the gift, soon my cock was as hard as steel. I covered my lap with a large gift and continued to watch. Carols panties barely covered her pussy and she had a very defined camel toe with the material of her panties pulled up between the lips of her pussy. I could see darkness through the material of her panties; it was obvious she did not shave her pubic hair like her sister. This was turning out to be a wonderful Christmas. I was broken from my trance as I heard my wife say, “Gary, open your gift”. My wife Anne was sitting in a chair across the room behind Carol and could not see the show that had been going on. You see Carol is my sister in law who was going to be staying at our house until New Years Day; this was the first time she had come to stay at our house for an extended visit. Carol is a real beauty. She is about 5ft. 8 inches tall. Fairly full figured, not fat at all just large in all the right places. Very large beautiful breast and a cute bubble butt. Her hair is dark brown and goes down to about the middle of her back. Her eyes are green and she has the cutest pug nose. Anne is just a little shorted than Carol, both have dark hair, but Anne’s breasts are quite a bit smaller than Carols, they both have large perfectly shaped butts. Anne keeps her pussy completely shaved and has since we were married. I unwrapped the large gift keeping it across my lap after I did. My sleeping pants were stretched tight with my hard cock. Then it happened, Carol said, “Unwrap this one next” as she crawled over to me and grabbed the unwrapped gift off of my lap. My cock sprang upward as she lifted the gift off of my lap and I saw Carol look down and her mouth opened as If to say something but she didn’t. It was a good thing Carol was between me and my wife or I am sure she would have noticed my hard cock too. I didn’t move and didn’t know what to do or say. Carol just sat the next gift down on mp lap, careful to put if in front of my hard cock to hide it from my wife, she looked up at me and winked then turned and told my wife, “I want to see you open that one first”, as she pointed to a gift laying beside her. I knew then that this was going to be quite a week. I was off for the holidays but my wife had to work Monday through Thursday then was going to be off for New Years Eve and the weekend. Carol would be flying back home on Sunday. We finally got through unwrapping our gifts; I kept one gift in my lap as we did. Anne got up to go make some coffee and I got up to go take a shower. I turned the hot water on as I slid my clothes off. I pulled the shower curtain closed and stepped under the hot water letting it fall around my shoulders as I tried to relax, my cock was still very hard as I thought about my sister in law. I lathered my hair with shampoo and thought I heard a noise as I rinsed out the soap, when I opened my eyes there was Carol peeking around the curtain. I told her to get out of here before her sister caught her. She said, “She is making breakfast so I slipped back here to get a better look at that cock of yours”. She was looking down at my cock and simply said, “Nice” as she closed the curtain and left. I just shook my head as I slid in behind the shower curtains feeling the hot water rain over my head. My cock was as hard as steel as I lathered up the soap to wash. I put my clothes on and went to the kitchen. The two sisters were laughing and talking as I came in the room. Anne handed me a cup of coffee and I noticed that Carol had showered also. Her hair was wet and lying across her breast, she was wearing a white t-shirt and a pair of jeans. We ate breakfast together and the longer we were there the wetter Carol’s shirt got from her dripping hair. Her nipples were wet and it was almost as if she did not have a shirt covering her breast before we got through eating. Anne saw me looking at Carol’s breast and kicked me lightly in my leg smiling as she said, “Quit looking at Carol’s boobs and eat”. Both girls started laughing and I just shook my head and stared at my plate as I finished breakfast. The rest of the day was pretty uneventful we decided to watch a movie that evening and after the movie was over Carol said she was going on to bed. I followed a few minutes later and as I got to Carols bedroom door I noticed it was cracked open, her bedside lamp was on. Carol was sitting on the side of the bed spreading lotion onto her legs. The only thing she had on was a pair of panties. I slowed a little but did not stop and thought I saw her look up just as I was getting past her door. Our bedroom door was just across the hall and I was just fixing to crawl out of bed for another look when I heard Anne coming down the hall. She came in the bedroom partially closing our bedroom door behind her as she did. My cock was hard and I wanted to play and was glad when Anne eagerly pulled her gown over her head and on to the floor. Anne’s nipples were hard and her areolas were pulled up tightly around them. We cuddled and teased each other for a while then Anne pushed me back on my back and crawled on top of me. I watched as she guided my cock into her shaved pussy, gosh her pussy was soaking wet, as she settled down onto my hard cock and began sliding down on to it, I saw her, Carol was standing just outside our bedroom door. She was in the dark shadows but I could see her as she looked inside. My cock was hard as steel as I slowly made love to my wife. Anne had her back to the door and had no idea her sister was peeking inside. Anne was moaning softly as we began to pick up the pace. Making love to my wife with her sister watching was more than I could stand and soon I was emptying my balls deep inside my wife. My eyes were closed tight but when I opened them and looked, Carol was gone. I slept well that night but woke early wondering about my sister in law in the next room. I didn’t know where this week was going to go but I was sure looking forward to it. The rest of the weekend went by quickly and when I woke up Monday morning Anne had already left for work. I got out of bed and quietly walked out of my bedroom. Carols door was open and I saw her still asleep with the cover pulled down enough that one breast was exposed. Gosh her breasts were big. I stepped quietly inside her room to get a little better look, her areolas were very large, covering what looked like a third of her whole breast. Her nipple was almost flat with an indention in the middle of her nipple. I was about to turn and leave but noticed her nipple begin to grow outward and her areolas began to tighten up. Soon her nipple was hard standing straight out and when I looked up at her face I could see that she had her eyes just barely open and was watching me. She continued to pretend to be asleep so I went along with it and slipped outside. I wasn’t sure at that point what to do but thought it best if I left and waited to see if anything was going to happen. I heard her bathroom door open and the water turn on. I waited a few minutes and walked down the hall, her bathroom door was cracked open. I peeked inside and could see that Carol was in the shower. The opaque glass made it hard to see any details at all but I could tell she was busy washing herself and it was also clear her pussy was getting some special attention. I watched her wash until I saw her reach down to turn the water off then hurried back to the kitchen to start the coffee. It wasn’t long before Carol joined me in the kitchen. She looked beautiful; her skin was glowing from the hot shower she had just taken. She was wearing a white terry cloth robe that came down to mid thigh, her hair hung loosely across her shoulders. Her smile just melted me right then and there, I wanted this woman. I handed her a cup of coffee and we sat and chatted awhile. Carol wanted to make a fire in the fireplace so I told her I would go get the wood from outside. She met me at the back door and took the wood from me as I turned to go get more. When I walked into the living room Carol was on all four placing the wood inside the fireplace. I just froze in my tracks. The robe was only covering the top half of her ass and she was not wearing panties. Her pussy was framed by her nice full butt cheeks like a picture. Her legs were slightly apart and it looked like her pussy was pushed outward from her pubic mound. Her lips were open slightly but my immediate attention was drawn to her clit. The hood of her clit was very prominent. It looked to be about an inch and a half long and looked to cover more almost all of her clit. Her clit looked large about the size of the tip of my little finger. She was clearly completely shaved around her pussy but I could just see some pubic hair hanging down above her pussy. My cock was hard as a rock. Carol was looking right in my eyes as she told me to bring her the rest of the wood. She was smiling but also had the look of a woman that knew what she wanted and was about to get it. I handed her the wood and she asked for a match. I hurried off to find the matches and when I returned the robe she had been wearing was on the floor. All I could say was. “Wow!” Carol took the matches from me and told me to get out of my clothes. I stripped while watching her light the fire. Her large breasts were hanging downward and swung easily with every move she made. Her legs were slightly parted and her ass stuck out prominently. But my attention was drawn down between her legs; her pussy looked like a clam that was ready to open. It was easy to see her slit was already wet. My cock was hard and as the fire started to flicker she turned and looked straight up into my eyes and leaned forward taking my cock head into her mouth. She never lost eye contact with me as she sucked gently on the head of my cock. I watched her slowly close her eyes as she began taking more and more of my cock into her mouth. I’m not huge, just a little over 6 inches, but very thick. I could tell her mouth was really stretched as she tried to take it all inside her mouth. Carol pulled away from me and grabbed a pillow off of the couch and laid back on her back and said, “Lick me”. Her legs were spread apart and I saw the little triangle of dark brown pubic hair just above her big clit. Her right hand was already rubbing her pussy as I crawled between her legs. She smelled so incredibly fresh with just a hint of the musky smell of a woman aroused. As my tongue slid up the slit of her pussy her labia fell open exposing her open pussy and large clit to me. Carol was soaking wet and I saw her stomach jerk inward as my tongue brushed over her extended clit. I let my tongue make tiny circles around her engorged clit and soon felt both of her hands on the back of my head pressing me downward, urging me to lick harder, faster. Her hips were pushing up into my face as she pressed my face hard against her pussy. I licked and sucked on her clit until her whole body became rigid as the first of her orgasms shook her body. I crawled forward and Carol pulled me down to her and we kissed passionately. She whispered in my ear, “I want you now”. I started to position my cock at the entrance of her pussy but she had other ideas and pushed me back as she got on all fours. I eased up behind her and as she bent her head down to lay on a pillow; her pussy seemed to flare outward toward me. The lips of her pussy were wide open as I pushed my cock head into her. Carols pussy was so wet but still felt very tight. I held her hips as I slid further inside and felt her velvety warmness envelop my hard cock. Carol moaned loudly as my cock hit up against her cervix. I pulled back just a little but she pushed back hard and looked back over her shoulder with a grin. We started a slow sensual rhythm but soon Carol was urging me to go faster and harder. I watched her breast bouncing wildly with each thrust of my cock. Carol suddenly became rigid and I could feel her pussy contracting around my cock, I could not stand it any longer and began to cum with her. Her pussy seemed to milk my cock completely. I stayed pressed up against her butt until my cock went limp. Carol slid forward laying on her stomach and looked back at me with pure contentment on her face. What a week we shared. But New Year's Eve was the best I have ever had. I will tell you all about it if there is enough interest ...
