My mother-in-law and her dogs were staying with my wife and I for a couple of weeks while her husband was out of town. Things are great between all of us so I didn't mind she was here. She is also a very attractive woman. She is overweight a bit but has the most beautiful face. My wife has the same face which I definitely thank her mother for. In the mornings I'll make my coffee, check email, news sites, etc. but also like to masturbate before I take my shower and go to work. My wife likes to sleep late so I wake her up after my shower is done.
So this particular morning about 0615 I was reading stories, looking at pics, and jacking off (much like I'm doing now just thinking about it) and I hear my MIL's door open. The dogs ran by my dimly lit office so I quickly pulled my robe back together to cover my hard cock. My MIL walked by and it this point I had already switched back to my news site. She said "morning" as she went by to let the dogs out. I was a little nervous and excited all at the same time so my cock wouldn't go down. I heard the dogs come back in and to my surprise my MIL came in to ask me something. She put her hands on my shoulders and read a little news over my shoulder. The exchange was only about a minute but it felt like 10. I couldn't wait for her to leave so I could finish what I started. So she left and went to the bathroom as I had her dogs running around my feet. I pulled my cock out and with a few strokes I came into a towel I pulled from the dirty clothes. It was a great experience and maybe one day she'll help me out.
