Sexy Sister-In-Law

I have always been pretty handy at fixing things and building things. I built my deck and two friends' decks. My sister and brother-in-law wanted a deck off their back door. They asked if I could help as my brother-in-law was not very handy. He was lucky to figure out which end of a hammer to use. He was a great athlete, but dumb when it came to construction and repair work.

Bruce and Nan met in college. He was the starting quarterback and won a national championship. Nan was the cute little cheerleader. Nan was built differently from her sister/ my wife. My wife 5 ft 3" 140 lbs with DD boobs. Nan 5 ft 4" 125 lbs with B cup boobs. Blonde hair down to her shoulders. Bruce is 6 ft 2" lean 190 lbs.

I showed up the first day with all my tools. I was telling Bruce what to do as we got the framing done. We had most of the joists up when he told me he needed to get to a baseball game he was playing in.

I finished hanging the joists by myself. Nan came out and helped me a bit. I didn't mind, she seemed to know more than Bruce plus, I got some nice views down her top, when she would be leaning over.

We got half the decking done, when I had to call it a day. Nan invited me in for a beer and to cool off. We had a nice talk. She seemed to hint about being lonely as Bruce was always busy playing men's league baseball, hockey and football. We had finished our second beer, and I was about to leave. But Nan opened another beer and handed it to me. "Have another beer, I am going to take a quick shower. It won't take long."

After 2 beers I needed to take a piss. I walked down the hall to use the bathroom which went past the master bedroom. The door was open and so was the bathroom door. I got a quick glimpse of Nan completely naked getting into the shower. Her image was burned into my brain.

She had a cute little ass, trimmed bush, pert tits and hard nipples that were light pink. I took a long piss and tried to time it so I could see her coming out of the shower. But no such luck.

She joined me back in the kitchen wearing her white terry cloth bathrobe. I was occasionally getting flashed of her pussy and tits. My cock was swelling and I kept trying to hide it.

I finished my beer and told her I should get heading home. She stood up and gave me a hug. God it felt good. I could feel her tits pressed against me and definitely could tell her nipples were hard. I froze as I felt her body pressed against my hard cock. She then kissed me on the cheek.

"You better get home and have my sister take care of that for you." She said with a smile, while looking down at my bulge.

"Oh my god, I am so sorry. I don't know what to say." I told her.

"It's no big deal. It's a nice compliment for me. Now get going before I decide to take care of it."

I headed home feeling so guilty. But yet, it was exciting.

Next day I showed up. Bruce isn't home. He has baseball and hockey all day. Nan came out to help me wearing very small shorts and a muscle shirt with no bra! I could just make out her nipples. We worked well together. It was hot and we were sweaty. With her shirt getting wet her nipples were very clear. We finished the decking and the railing. We were done.

"I can't thank you enough for all your help Brian. Time to get inside the house and enjoy the AC and a beer."

"I should get going. I need a shower badly." I told her.

"Bullshit, you can shower here. I am home all alone until 8 tonight and need some company for at least a little while. You can shower first; I will through your clothes in wash."

I agreed. Nan put out a towel and a bathrobe for me to wear while my clothes were being washed.

After I showered, I went to the kitchen, and Nan handed me a beer. "My turn, I will be right back." Nan said and she could clearly see me staring at her see through top.

Nan wasn't gone long before she returned wearing her white robe with wet hair. In the blink of an eye, she suddenly was sitting on my lap straddling me.

"I have always wanted to do this ever since my sister told me that you were amazing in bed."

Nan kissed me deeply. I had always fantasized about her. I returned the kiss. Without realizing it, I had pushed her robe down and my hands were playing with her tits, while her hand was stroking my now hard cock.

Our robes had now fallen off, and Nan was guiding my hard cock into her hot wet pussy. My mouth to her tits. I sucked and licked them as she started to ride my cock.

"Oh fuck, Nan, you feel so good." I moaned between my sucking and licking.

"Fuck, my pussy feels so full. You feel amazing too."

I decided to take charge. I stood up and she wrapped her legs around me. I carried her over to the center island and sat her down on it. Putting her legs over my shoulders my mouth found her hot wet pussy. I was licking and sucking her pussy and clit, while I my finger found her G Spot.

"Oh fuck, oh fuck" Nan screamed as she came twice in two minutes.

Picking her up off the counter I carried her over to the kitchen table and bent her over it. I guided my cock inside her. Grabbing her hips I thrust 3 times deep inside her. She grunted with pleasure with each thrust.

"My sister-in-law is my little slut, aren't you?" I asked as I thrust again.

"Yes, yes, I'm your slut. Fuck me, fuck me hard. I want your cum deep inside me." She yelled.

Grabbing a handful of her hair and pulling on it, I fucked her hard, deep and fast. It didn't take long and I shot 3 ropes of my seed deep inside her. I was holding her up as her knees went weak. I pulled out and told her to get on her knees and suck my cock back to life.

Nan's oral skills were much better than her sister's. It didn't take long before I was hard again. As I was getting close, I pulled out and shot my load on her face, tits and into her mouth.

Smiling, Nan licked up as much of my seed as she could. Giving my cock a few more deep sucks, she drained me.

"Come on, I think we need to shower again." I said as I helped her up.

We took a long shower together with a little more sex. When we got out our clothes were dry.

We had a long deep kiss and said our goodbyes.

A couple of weeks later my wife and I were invited to their house for dinner on their new deck.

Bruce said, "Thanks for the help on the deck. What do I owe you?"

"Nothing Bruce. It's been taken care of already."

He looked dumbfounded as he had no idea what I was talking about.
