"Well, hello there!" said my sister-in-law Kim as she greeted me at the front door to her and John's house. They had asked me over for the weekend to help John build a deck on the back of their house.
Kim wasn't a classical beauty but there was something about her. She was short, only 4 feet 11 and a half inches tall, but you better not forget that half inch or she would take your head off. She had been a cheerleader so she had a tight athletic body. I really liked watching her walk and wiggle that tight little ass of hers. She wore her dishwater blonde hair at shoulder length but it framed her piercing blue eyes that cut through you like a laser beam when she looked at you. Right below those eyes were a button nose and a wide mouth filled with lots of white teeth. Perky firm B cup tits sat on her chest with large nipples that really poked at the cloth of her blouse when it was cold. I was thankful that they kept the heat turned down low to save money so her chest gave me a show every time I went over there. Finishing off the package was a wasp waist and a flat stomach that didn't look like she had given birth to two kids. All of this was carried along by a set of shapely legs. Oh and that ass, have I mentioned that great tight ass of hers?
"Hi Kim!" I said, "His highness in the family room?"
"He sure is" said Kim.
As I walked down the hallway to the family room I thought about how my wife, John's sister, had told me not to talk about the couple's marriage. Cindy had told me that John had said he and Kim were having problems and were thinking about spending time apart for a while.
"Hey there sport!" John greeted me when I entered the family room, "Want a beer?
"Sure" I said, "Never turn down free beer."
"Well, you will earn it this weekend." said John, "That deck is going to be a lot of work."
I sipped on a cold Corona as I sat on the family room couch and watched the ball game on John's flat screen. I suddenly noticed that it was only the three of us.
"Where's the kids?" I asked.
"I thought they would be in the way and slow us down." said John, "So they are staying over at a friend's house this weekend."
"So Kim's going to help us build the deck?" I questioned.
"No way" laughed Kim, "I am here to supervise!"
It was cold as usual and Kim's big nipples were poking at her blouse. They really put on a show as she laughed and the hard nipples rubbed up and down against the smooth silk of her blouse. I could feel my cock start to stiffen and hoped neither Kim or John noticed.
Don't get me wrong, I love my wife. Being John's sister she has dark brown hair and eyes just like he does. Like her mother, she has a curvy voluptuous body with a large rack and wide hips. The only thing about Cindy is that she is not very adventurous in the bedroom. Suck a little, or sixty-nine a little, some missionary or cowgirl and it's all over. As a result our sex life if fine but a little predictable.
Maybe that's why I am drawn to Kim. Besides that petite cute girl appeal, Kim had that wide mouth and tight little ass. Along with that wide mouth came a very big tongue. I dreamed more than once of her licking my prick with that big tongue and then sucking me with that mouth. I also dreamed of putting my hands on and cock into that perfect little ass of hers. Fantasies, just fantasies.
We watched the end of the game and the news. All three of us got up to get ready for bed.
"You'll be in the guest room." Kim said in reply to my questioning look.
Just then the phone rang and John answered. John talked for a while and all he seemed to be saying was Yes. He hung up the phone and Kim glared at him with a face like a thundercloud.
"Well!" Kim spat out, "You have to go in, right?"
"It's my job." said John, "I am on call. I have to go in for an emergency."
"It's good SOMEONE will be here tonight." said Kim, "At least I will have company during the storm!"
The forecast we had just seen on the evening news had said we had a good chance of severe thunderstorms tonight. Kim marched out of the room and upstairs so hard John and I could hear her all the way up to their bedroom. Then we heard the bedroom door slam shut.
"Kim's scared of storms." said John, "I am glad you will be here tonight. This sounds serious so I may not be home until early in the morning."
John took off to the garage and I heard his car pull out of the driveway. Suddenly I was standing along in the family room and feeling a little sheepish, like I had just seen something I should never have seen. I walked upstairs to the guest room. It was small with only a twin bed, but it was serviceable. I took off my clothes, turned out the light, and went to bed. It had been a long week for me too and in a minute I was asleep.
Suddenly I was awake but it was dark and I couldn't really see anything. My eyes adjusted to the darkness and I realized that someone was standing beside the bed. Suddenly there was a crash of thunder and a lightening bold lit up the room. I could see Kim standing next to the bed dressed in only a see through with baby doll nighty top trembling.
"Can you keep me company?" said Kim in a scared little girl voice.
"Sure" I said still only half awake.
"Come to my room." said Kim, "We both won't fit in this little bed here in the guest room."
Still groggy and now aware that there was an almost constant room of thunder and frequent flashes of lightening I followed Kim to her and John's bedroom. Kim got into the right side of the bed and pulled up the covers. I got into the left and pulled the covers onto my own body. Kim was laying with her back to me when a crash of thunder that sounded very loud and very close made her jump.
"Can you hold me?" Kim said.
I slid over to her and put my arm around her trembling body. I was suddenly aware that as was normal for me when I sleep, I was totally naked. I felt her trembling body against mine since the sheer nighty she wore was the closest thing to having nothing on at all. Her body was cool but she was making me hot. The decision was made, this was my only chance. I slid my arm up so that I could put a hand on one of those cute little tits of hers. I could feel the firm little mound through the sheer nighty and I started to slowly rub the firm little boob. Her nipple started to get hard and so I concentrated on rubbing it making it harder still.
I slid my left arm under Kim's neck and using a move I had learned with Cindy, right down the front of her nighty. Now my left hand was massaging her naked left tit under the nighty. Kim didn't protest and in fact moved her arms to give me better access to her nice little jugs. Both nipples were getting hard so leaving my left hand to work her naked boobs, I slid my right hand down to her thighs. I stroked and caressed Kim's thighs and pulled my body close to hers. My cock was now pressed up against that great ass.
On each stroke of her shapely thighs I lengthened my caress. Each time my hand pushed a little farther down her thighs and a little farther up towards her crotch. The stroking motion pushed the flimsy nighty out of the way and suddenly I was stroking her pubic mound. Kim's bush was surprisingly soft and downy. I dropped the pretext of massaging her thighs and concentrated on her cunt instead. I rubbed the mound in slow circles and then pushed two of my fingers between the lips.
"Ohhh!" moaned Kim. She suddenly turned her head towards mine and kissed me firmly on the mouth.
I was now stroking and gently twisting her hard large nipples with my left hand while the fingers of my right hand burrowed their way into her very wet quim. I rubbed the hood of her clit in gentle circles causing Kim to push her tongue into my mouth. Her tongue was large and its wet probing of my mouth felt great. I pushed my lips tight onto hers to enjoy as much as I could of her enticing tongue that was wiggling in my mouth.
Suddenly Kim twisted away from me and jumped out of the bed.
