Secret Arrangements

My wife convinced me to let my SIL move in with us at first for a few months to help her get on her feet after my brother her husband past. I was against it at first but eventually caved in. She was going to save some money pay off bills while she lived with us. We had the room we have a large home no kids she had no kids. She was a mess for a while and never really looked at her as I do now. She is in her early 40s brunette shoulder length hair w eta da glasses. I guess I never really looked at her in any other way other than my sister in law. That all changed about 5 weeks after she moved in. I work from home and on occasion leave and come back through out the day. I had left one morning and came back a few hours later and she was home and by the pool. I didn’t pay attention until she walked in to grab a drink from the fridge and I got to see her in a very skimpy bikini that revealed to me her tight body. She had nice sized tits and some hips. She was hot I instantly got a boner and found myself constantly checking her out. I stopped working and went and hung out with her by the pool. We chatted and talked she thanked me for agreeing to let her stay and she said I start to pay a little rent if you want. I said no not to worry to save up. She laughed and said yes I bet you want me out of here I know. I then said jokingly hello no the way you look right now you can stay here as long as you want. She was quite and then said thanks it had been a while since she felt like she did right now. I jumped into the pool and came out she swam over and we talked some more. It started out as playing around and before we knew it we where kissing. She let me eat her out and she then sucked and swallowed for me. That night when we where all together my wife everything was normal. Next morning we all we t to work i didn’t have to leave that day she went and was aback around 4 my wife had a long shift at the hospital and wasn’t so back until 8. I sat on the couch when she came over and proceeded to pull my shorts down and started to lick my balls. She jacked me off while licking my balls and eventually sucking me to completion. Always swallowing as much and licking me clean. She then laid back on the couch and I’d return the favor paying special attention to her ass. Every time I’d lick her ass she seems to push back and try and force my tongue inside her butt. This went on for about a month not really talking about it and only happened in the evening. She is a pharmaceutical rep so her schedule is a little flexible. I was in the kitchen when she came in dressed to kill in a close and skirt that hugged her every curve. She was leaning over the counter when I walked up from behind her and lifted her skirt to see her thick ass in a g string. She let me and was thinking I wanted to eat her ass since I started to lick it her little rose bud. She leaned over the counter and really stuck her ass out for me I pulled my cock out and then slowly started to push into her ass. She let out a small sigh and said oh just taking it now huh. A lot of spit and I was in. Fucked her ass in my kitchen and gave it to her rough. That day we joked that she was now paying rent. It’s been a year my wife is happy because they get along I’m happy because instead of getting sex maybe 2 times a month I’m using my SIL as a fuck doll and she is loving it. She sometimes calls in sick to get fucked or will have me meet her for lunch and gets a protein shake directly from my balls. To be honest I’m hoping she doesn’t move out.
