I just fucked my sister-in-law. She is 10 years younger than me and the wife. She had a bad marriage and ended up moving in with me and my family two months ago. She is a lot hotter than her sister (my wife) and I have wanted to fuck her since me and her sister started dating over 8 years ago.

Well, if finally happened yesterday. My wife was at work, I was working from home. My SIL was planning on taking the kids to the community pool and get some sun for herself. When she was leaving she looked so sexy wearing a 2 piece bikini. I couldn't help but get an erection. I walked them out to the driveway and waved good bye.

I went back into the house and had to relieve myself. I pulled my cock out and stroked it for only a few minutes thinking about how hot her body looked in that 2 piece. I came within 2 minutes. So, I cleaned myself up and went to my office to work on some stuff. I couldn't keep my mind from drifting back to her nice tight ass bouncing away when she left earlier. I decided to look at some porn and jack off again.

I had the porn going, an older man plowing a younger girl from behind, I had my hard cock in hand stroking it when I head someone say, "need some help with that?" I turned around and it was my SIL. She was standing there with her top pulled to the side tweeking one of her nipples. She was looking at my cock with a devilish grin on her face.

I said, "any help you would like to give would be appreciated". She came over to me and dropped to her knees and took my cock into her mouth while looking at me right in the eyes. She was so sexy with my cock disappearing into her mouth. She sucked cock a lot better than her older sister. She could deep throat me and hold me there for a few seconds without gagging. He sister had only deep throated me one time. She was doing such a good job I thought I was going to cum, so I grabbed her up and sat her on my desk, got between her legs, pulled her bottom off, and dove into her pussy with my tongue. She tasted so sweet, I licked her for all I was worth. She started moaning and grinding her pussy into my mouth and had her first orgasm. She grabbed my head and shoved it into her pussy.

She then really surprised me, she pulled my head back by my hair, I looked up at her, and she had this dominating look on her face and sternly said, "fuck me with that big hard cock right NOW!"

I stood up and put my cock up to her pussy and rubbed the head up and down her slit, she was grabbing my ass and pulling me in. I put the head right up to her pussy opening and pushed into heaven. She was the tightest pussy that I have ever been inside. She let out a loud gasp and screamed, "FUCK ME HARD!!" I fucked her for all I was worth slamming into her as deep as I could get. This went on for about 5 minutes and I was getting close to cumming, so I slowed down my strokes and leaned down and took one of her nipples into my mouth. As I started to suck on her nipple, she started her second orgasm, this in turn made me start cumming deep inside her.

As soon as I stopped shooting inside her, she dropped back to her knees and took me into her mouth again, she sucked me until I was hard again. She then turned around and bent over my desk and told me to fuck her ass. I licked and tongued it some to get it good and wet then I fucked her ass for a good 20 minutes, she had her 3rd and 4th orgasms during the ass fucking.

She told me that she wanted me to cum in her pussy again, so when I was ready to cum I pulled out of her ass and stuck it back into her pussy and filled her up a second time.

My wife still doesn't know that me and her sister fuck at least 3 time a week and that she is pregnant with my baby. I hope she never moves out.
