How I made my mother in law my bitch 10 (another sister) I had just dropped off my mother in law after I fucked her silly again tonight when I stopped at a bar for a minute to have a beer before I went home to my wife. Knowing she would be sleeping I figured I had all night.
When I pulled into the parking lot I noticed a couple going at it in their car. I love the voyeur stuff so I decided to park a little close to them. What I saw was a woman giving her man a great blowjob well ok the back of her head for starters but isn't any blow job a great one? After a couple minutes she moved up off of her knees and I am sure she was about to ride him when all of a sudden I realized that I knew who it was.. I couldn't believe what I saw but one of my wife's sisters lifting her skirt and straddling a man who was not her boyfriend. WOW here was my sister in law the one who teaches grade 2 students riding some guy in the parking lot. My cock got harder seeing who it was and she never even looked my way as I was watching from the seat of my truck. With my phone I was taking video as she started to ride the lucky guy up and down and back and forth. His hands caressed her little tits under her top but soon she was lifting her shirt over her head.. Her hands grabbed onto his shoulders as she was reaching orgasm. She much have cum a couple times before he had her get off of him and he had her turn around so he could fuck her from behind..
What an amazing body she has she is 5'9 and about 118 pounds with the most amazing ass you will ever see.. Now I was rubbing my cock as his cock was slamming into her hard.. The street light went out for a second and it got dark and I thought it was over but the light came back on just in time to see they had switched places and he was nailing her on as she sat on the chair.. I don't know what made her look over my way but she did and all of a sudden she freaked out and started to panic. She was trying to push him off and grab for her cloth and he looked totally lost. A couple minutes passed when she got out of the car and came over pleading for me to not say a word and she wont ever do it again and all the other crap people say when they get caught. I looked at her and told her to shut up and get in the truck..
The guy in the car just took off so I assume she told him who I was.. When she got in the truck she was crying and she looked awful but sexy as hell. She kept saying how sorry she was and how she has never done anything like that before..When I told her yea well your going to do it again right now. She pleaded with me that it was wrong what she did and how she cant do that to her sister as I made the comment but its ok to do it to your BF? After about three more minutes of her crying I said look you don't have a choice You don't do as your told and I will show your BF the video and then I will post it on the internet so your school will see it so you really don't have much of a choice. I leaned over towards her to kiss her but she wouldn't kiss me back so I grabbed her by the back of the hair and told her.. You can do this the nice way or we can do it the rough way your choice.. She leaned forward and kissed me back. I wiped away the tears from her face and I started to take my pants off When i started to kiss her again I took her hand and placed it on my cock.. OMG its huge that wont fit. I told her she was going to try and in saying that I grabbed the back of her head and guided it towards my cock. She did her best as her head bobbed up and down I was telling her how hot she was and how out of all her sisters I wanted to fuck her the most. I don't know if that turned her on or what but she seemed to squeeze my cock a little harder and take a little more into her mouth. I was feeling her tits with one hand and my other hand was running back and forth between her thighs and over her great ass. When I made contact with her pussy she let out a shiver. She was soaked when my fingers finally stopped roaming and found the inside of her lips.. She stopped sucking my cock for a second and looked at me with total lust.. Then her eyes closed as she squeezed her thighs and started to cum just like that on my fingers. I continued to finger her pussy making sure it will be easier for my cock to slide into her.. I don't know if she was trying to suck my cock like a champ so I would cum before I fucked her but I wasn't going to take that chance..
I lifted her head off of my cock and told her it was time. Again she pleaded we cant and how she would suck my cock till I cum but I told her to straddle me. She did just that lifting her her leg over mine and taking my cock and guiding it into her pussy.. Slowly she sank down trying not to look at me..her hands resting on the seat but I could feel her feeling her pussy getting filled. When she reached the bottom she sat there for a second waiting for her pussy to stretch to the thickness.. I could her her moan and mumble OMG under her breath before she started to ride up my shaft. I told her to look at me and she didn't.. She was looking out the window trying not to enjoy it but it wasn't long before she actually started a rhythm.. Look at me I said to her again.. This time she looked right into my eyes and leaned forward and kissed me. Within seconds she shuttered as she had another orgasm. I wanted to see her on her back and I wanted to taste her pussy for years now so here was my chance. Eating her pussy till she came again but It was getting late so I shifted and laid her down. She was looking into my eyes when I started thrusting in and out of her pussy. Her hands were now on my hips setting her own pace.. I told her it wasn't going to be long till I cum and she said to cum on her and not inside. Like I was going to listen.. I reached over and grabbed my camera and she pleaded no but I wasn't going to let this moment go away ever.. She pleaded but I didn't care I took pictures of her laying there with my cock in her. I had her turn over so i could fuck her diggy style and to look at her ass and I told her next time I will be fucking her ass and to be prepared..She started yelling about a next time as I told her to shut the fuck up and learn her place in my life will be to fill my needs now.. When I told her she was going to swallow my load and she said she doesn't do that.. I told her you do now.. With that I pulled out and grabbed her by the hair till her face was inches from my cock.. My load shot all over her face as she sat there taking it all again. I told her Open your mouth and clean my cock so there isn't a mess.. So I took another pick with her face full of cum and my cock in her mouth. God she looked hot.
. When she sat there she asked me to delete the picks and she would do anything I asked. I told her with the picks she will have no choice. I then told her to sit back and spread her legs. (click, click) now finger your pussy I want to see them deep to. (click click click) I told her the hell with your BF seeing these could you imagine what the school board would say if they ever seen them.. She was crying again when i told her I will keep my word and not show anyone as long as she did what she was told..Watching her with her fingers in her pussy I felt my cock twitch so I did make her suck my cock again. This time having her swallow it all. I drove her to her car and it was perfect her BF just pulled up and asked her where she was.. She said she went to the house down the street and called me to give her a boost.. Her BF knows nothing about cars so it went well.. I pretended to fix her car and I told her I she was good to go.. Her BF looked at me and thanked me for taking care of her and I told him it was totally my pleasure.. She didn't say a word and got in her car and left.. I went home and my wife was still sleeping.. I leaned over and kissed her on the cheek. M cock was hard again thinking about her sister as I pulled down my wife's pj,s She woke up and told me to fuck off and not to even try it.. Thank god for in laws. If it wasn't for them I would have to go outside the family.
