My mother in law is in her late 50's - still very attractive. I stop by for lunch every now and then and sometimes sleep over for work purposes. Often she is home alone and lately I have been masturbating while she is in the house. I think she caught me one day but i was never sure and she never indicated that she did.

She has definitely seen my cock though as one time i was sleeping during the day and my cock was hanging out of my boxers. I was lying uncovered half awake and heard her walk past and stop at the door.

Last month after a shower i masturbated in the bathroom knowing she was close by and had a good chance of hearing me. I have done this a few times since then and am certain she was standing outside the door the last time.

This week we were in the same room trying to sort out an electrical issue in her house. I was on the computer and she was behind me going through a folder. I carefully pulled out my cock and slowly masturbated without cumming while she sat just behind me. She wouldn't have been able to see my dick but she might have been able to see my left arm from behind moving back and forth. I had to leave and she was disappointed i wasnt staying for dinner.

I got home that day and blew a massive load.

I'm waiting for the day when she offers to help me out with my hard cock. What i wouldn't have given to have her spin my chair around yesterday and suck me off. I'd love to blow over her face as well as see her swallow me.

Every week it seems we are etching closer to this happening. It's exciting. It's wrong. It's hard to stop. I want to fuck her badly. I'm sure she needs it. I'm sure she is thinking the same thing and knows im the one that will fuck her the best. Time will tell. Thanks for letting me get this of my chest.
