"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.
