Sister In Law 31

After my wife's sister got a divorce she moved in with us and since I work from home we were alone almost every day for hours.

Not long after she moved in I began to notice whenever my wife wasn't home Katie would walk around the house with some extremely revealing outfits. At first I tried my best not to look but I am a man and just looking at her sexy body in those sexy outfits would give me a hard on. I still didn't think anything about it but after a while I began to wonder if she was actually trying to come on to me.

She would come into my office wearing a shirt that showed plenty of her big tits and some of the tightest shorts she could fit into or sometimes she would be wearing a short skirt. She would always bend over in front of me giving me a great view of her gorgeous ass making my my already hard dick even harder. Sometimes I would get so horny from just looking at her that as soon as she left the room I would have to jack off.

What made it even worse was that my wife hardly ever dressed like that and I have always loved looking at women wearing sexy clothes. My wife isn't very sexual either, she's okay with us having sex three or four times a month and it always has to be in the missionary position with the lights off.

Then a few weeks ago my wife went to visit one of her friends for the weekend which meant Katie and I would be completely alone for three days but I never expected anything to actually happen between the two of us.

My wife left Thursday morning and wouldn't be home until sometime Sunday afternoon. That day I had a lot of work to get done and I was busy in my office when Katie came in and asked if I wanted anything for lunch.

When I looked up I could feel my dick starting to get hard instantly. She was wearing a very sexy bikini and when she saw the way I was looking at her she said that she was about to go lay out by the pool but wanted to see if I wanted some lunch first. I wanted to eat something alright but it wasn't food.

I told her I was fine and when she turned to walk out of my office I saw that her bikini bottom was a thong and I could see most of her gorgeous ass.

After she went outside I tried my best to concentrate on my work but all I could think about was my sexy sister-in-law laying out by the pool in that sexy bikini.

Somehow I managed to finish what I was working on and I decided to go put on my trunks and join Katie out by the pool.

When I walked outside I asked her if she would mind if I joined her and she said "I would love that Jimmie because I was getting kind of lonely out here by myself."

I laid in the chair next to her and she asked if I wanted a beer, I told her I would love one so she got up and went over to the cooler. When she bent over to get us both a beer she gave me an excellent view of her gorgeous ass and I could feel my dick starting to get hard again.

It was like that the rest of the afternoon while we were out by the pool and by the time I went to take a shower it took every ounce of restraint I had not to jack off while I was in the shower. I had a feeling that the show was far from over and I knew I was going to be good and horny by the time I went to bed that night and I would jack off then.

When I went into the kitchen Katie was already fixing us something for dinner. She was wearing one of her low cut tops that really showed off her big tits perfectly and one of the shortest skirts I had ever seen her wear.

She said that dinner would be ready in about half an hour and asked if I wanted a drink while I waited. I could make it but she insisted on making it for me and when she bent over to get the bottle of bourbon out of the cabinet I saw she wasn't wearing any panties and I could feel myself getting hard all over again.

After she made us both a drink she went to get something out of the refrigerator, bending over again giving me another great view of her ass. I was getting so horny that I was beginning to wonder if I could wait until I went to bed to get myself off.

Somehow I made it through dinner and a few more drinks after Katie cleaned the kitchen and I told her I was going to bed.

After I took off my clothes I laid in the bed and closed my eyes and pictured Katie in that sexy bikini while I slowly stroked my hard cock.

I was really getting into stroking my cock while I fantasized I was making love to my sexy sister-in-law and all of a sudden I heard Katie say "would you like me to help you with that?"

Shocked, I opened my eyes and saw Katie was now completely naked. I asked her what she thought she was doing and she moved next to the bed, reached down and started stroking my cock as she said "I've seen the way you look at me Jimmie and I know you want this as much as I do."

I told her that we shouldn't be doing this but I didn't try to stop her because her hand moving up and down on my cock felt so good I really didn't want to.

Katie moved on the bed with me as she continued to stroke my cock and she said "you're so hard Jimmie, I bet you would love me to suck your hard cock." She started kissing her way down my chest and stomach as she continued to stroke my cock and I soon felt her soft tongue moving over the head and I couldn't help moaning.

I watched as she ran her tongue down my cock to my balls and after she tickled them for a second she ran her tongue back up to the head.

She did that a couple of times and each time she moved her tongue up to the head she would lick up the pre cum leaking from the tip.

She then wrapped her lips around the head and slowly sucked my cock inside her warm mouth and I was soon moaning how good her mouth felt on my cock. I couldn't remember the last time I had a blow job and it had been even longer since a woman seemed to be enjoying it as much as I was.

Katie was now deep throating my entire shaft and I could feel the cum rising up from my balls. I moaned that she was going to make me cum if she didn't stop and that just seemed to make her suck harder until I couldn't hold back any longer. I moaned I was cumming as I came harder than I had in a very long time.

Katie continued to suck my cock, swallowing my entire load until I finally stopped cumming.

She then moved up and we kissed for the first time. She then said "I haven't felt a guy cum like that in years and I'm so horny now and I need you to make me cum, I want you to eat my pussy and make me cum with your tongue."

Katie rolled over on her back pulling me with her and I immediately moved down to suck her hard nipples. As I switched from one nipple to the other she was moaning how sensitive her nipples were and she could already feel herself getting ready to have her first orgasm.

I continued to suck her nipples as I moved my hand down between her legs and started to rub her swollen clit and within just a few seconds Katie was crying out that she was cumming and I could feel her warm juices covering my fingers.

As she was coming down from her first orgasm I moved down between her legs and started licking up her sweet juices. Her pussy was completely shaven except for a tiny patch of red hair just above her pussy and I could have eaten her pussy for hours.

As I began to run my tongue up and down her smooth lips Katie was moaning how much she loved my tongue on her pussy and she couldn't wait for me to make her cum again.

I moved my tongue up to flick her clit before sucking it into my mouth. As i sucked her clit I continued to flick it with my tongue as I plunge a finger inside her. I couldn't get over how tight she was and I couldn't wait to sick my hard cock deep inside her tight juicy cunt.

By then Katie had two handfuls of my hair, pulling it as she moaned she was going to cum again. I then added a second finger to her tight pussy and one to her even tighter ass and started pumping them into her until I could feel her body beginning to shake as she cried out "oh my God I'm cumming again, I'm cumming so hard."

She then did something I had not experienced with my wife, Katie juices actually started to squirt from her pussy. I quickly pulled my fingers out of her so I could suck her pussy and drink her sweet cum.

As she was coming down from her orgasm I knew that there was no turning back now and I wanted to feel her tight pussy on my cock. I moved up and started to rub the head of my rejuvenated hard on up and down her wet lips. Katie was soon moaning she wanted to feel me inside her and I started to push inside her.

Once I had my cock completely inside her tight pussy I started to slowly move in and out and I still couldn't get over how tight she was. I propped myself up so I could look down at her while I moved my cock in and out of her.

Katie was soon moaning for me to fuck her harder and I slowly increased my thrusts until I was slamming my cock deep inside her and she moaned "oh Jimmie, you're cock feels so good inside me, you're going to make me cum again."

I was able to last a little longer the second time but her pussy was so tight I could soon feel myself getting ready to explode again.

When I told her I was going to cum again she wrapped her legs around me and moaned "cum inside me baby, I want to feel you filling my pussy with your cum."

I lasted a few more seconds before I slammed deep inside her and started cumming inside her. As I was cumming she moaned she could feel my cum shooting deep inside her and she was cumming with me.

As we were laying there afterwards Katie said "that was amazing, I haven't had that many orgasms since before I got married." I told her that I couldn't remember the last time I came more than one time in the same night.

I then felt her starting to stroke my flaccid member and she said "you want to go again?" and I told her I didn't know if I could even get it up again.

She said "you just leave that up to me baby" and she moved down, taking my limp cock in her mouth and started to suck me again.

I was surprised when I could feel myself getting hard for the third time. Katie continued to move her mouth up and down on my cock until she had me fully hard again and said "this time I'm going to make love to you until you cum inside me again."

She moved on top of me and slowly eased her tight juicy cunt down on my hard cock as she moaned how much she loved my cock inside her.

Aa Katie began to grind her pussy on my cock I reached up to squeeze her beautiful tits and pinch her hard pink nipples.

Katie moaned "oh yes, you're hitting my g-spot and I'm going to cum so hard" and a second later she cried out she was cumming and I could feel her warm juices soaking my crotch.

I'm not sure how much longer she was riding me before I shot my third load of the night and as I was cumming inside her again she had another orgasm.

We spent the next two days having more sex than I'd had with my wife in the last five years. I don't think Katie even wore any clothes the rest of the weekend. We had sex in my office, on the kitchen counter, in the living room, in the shower and any where else you can imagine.

Since my wife got home we have continued to make love every chance we get and it just keeps getting better and hotter.
