My wife Casey and I moved away from our families in the city to a small country town a short time after getting married. Both in our mid twenties and enjoying life we loved the move.
Casey is an attractive brunet with a slim athletic body and manages to maintain large natural 34DD breasts. I was a happy man and had a great sex life.
One day over the summer her mother called and was in a bit of a fluster over house repairs she needed done and couldn't afford.
Her mother Anna became a widow at a young age and was only on a small income, so the pressure came on me to help. We live a few hours away so the easiest way around it was for me to travel there and stay a week.
I made out I wasn't impressed about living with my mother in-law but agreed just to keep the peace. Deep down though I really didn't mind as I had always had a thing for her mother Anna.
Anna looked after her self, she was a red head in her late 40's with large heavy motherly looking breasts which I frequently fantasised about ever since I started dating Casey.
I arrived at Anna's on a hot summers day morning and knocked at the door, moments later Anna opened the door to greet me. She was wearing a skirt and lemon coloured t-shirt which was straining to hold back her large breasts.
I think it was the first time I had seen her dressed so casually, and couldn't help my eyes being drawn to her pendulous breasts
She caught my eyes as they glanced downward at her chest, and I felt a bit embarrassed.
I followed her inside and got settled in, then started the repair work trying to think of something other than that lemon t-shirt. Anna called out that lunch was ready around mid day.
I went inside and to my shock and pleasure Anna had changed again was now wearing the same skirt but had changed into a sheer white blouse making it easy to see her straining bra and the faint outline of very large dark nipples.
My mind was wandering straight over to her and ripping open that blouse and burying my face deep in her huge cleavage. I felt my pulse quicken and a surge of blood enter my groin as my thoughts wandered. As the blood flow increased my bulge grew and I quickly took a seat opposite Anna to hide my growing erection. I struggled to eat lunch as I sat opposite her massive chest, the blood pounding in my groin.
She frequently caught my eyes wandering to her chest but didn't seem to mind so I didn't try to hide my interest.
After stretching my lunch break as long as possible I continued on with the repair work.
I was really struggling with what to think, surely I can't be interested in my mother in-law, if Casey ever found out it would be marriage over.
Anna came out and said she was going to get ready and go into town soon for some shopping.
Phew I thought I can think straight.
I was working up a ladder on the side of the house when the bathroom window near me popped open and I heard the shower turn on.
Oh god no I thought as the blood started to flow again, surely not.
My mind began to race I wanted so badly to see her naked body, both heads were pounding with excitement so I decided to move the ladder and see if I could get a view.
Anna came into view in the bathroom and began to undress, removing her skirt and blouse first, I was fully erect on a dam ladder. She removed her bra letting her heavy breasts fall and exposing those large dark nipples. I was so horny I thought I was going to cum right there on the ladder.
I watched as she showered and caressed her amazing body. Her eyes were closed and her hands slid over her body from her nipples to a nicely trimmed pubic area.
One of her hands began working at an incredibly fast pace between her legs while the other tugged gently on her left nipple.
Minutes later she moaned deeply and just as she turned the shower off my mobile phone rang. I fumbled for my phone and hurried down the ladder. Anna must have heard oh god what was she going to think. My son inlaw is a sick pervert.
I pretended to work but couldn't think straight.
Anna came outside and I was expecting her to say something, but she just said she was leaving now and glanced down at my groin. I glanced down myself and could see a massive precum stain on my shorts.
She just raised her eyebrows and said she would be back later and left.
