My mom and dad split up when I was 12 years old, with my mom bringing me up on her own from then on. Ocassionally I'd see my dad, but he always seemed to be busy with one new girlfriend after another.

This spring just gone, my mom died after suffering from cancer for over a year. My dad and I became a little closer but our relationship had definately changed as I'd matured without his guidance. I'd moved back into my moms rented house when she became ill, after leaving to live with a girlfriend. My girlfriend didn't like that I moved back and ditched me. her loss.

A few weeks after the funeral, I knew that the lease on the rented house was going to be up, so my dad said I could move in with him and his new bride, a woman I'd only met on a few ocassions. Her name is Kate and she is eight years my dads junior. She's very pretty and has what I soon learned was a fantastic body.

Life moved on and eventually I started to get passed, without forgetting, my moms death. I began to go out with friends again and even got new job. I also started to attend a gym close to where I worked. About four months after staring at the gym I was at home, my dad was at work and Kate was I thought in bed. I'd stripped to get into the shower and was crossing from my bedroom to the bathroom, when Kate walked up the stairs.

I've always known I was well endowed and even flaccid my cock is around seven inches. Kate looked directly at my cock, then took in my physique and smiled. I went bright red and quickly entered the bathroom. She was sat in the kitchen when I walked downstairs later and said nothing to me other than "You don't take after your father".

From that point on, and this is where I'm struggling, I'm sure kate has been flirting with me. I caught Kate a month or so back and she was totally naked sat on the couch, as if it was perfectly normal for her to be there naked, and I'm sure she masturbating. She didn't even try to cover herself up and believe me she looked stunning. Other times I've been sat oposite her on the couch and she's flashed me her neatly trimmed pussy, by spreading her legs slowly. Even if my dad has been sat there with her.

A fortnight ago, as I was getting ready to go out, kate walked into my bedroom and asked me if I wanted to travel with her the next day to a furniture store, as my dad was playing golf. Once again I was naked, but this time I couldn't just walk away and I'm ashamed to say I got an erection stood in front of my dads wife. Kate stood there without saying another word, looking at my cock and licking her lips. It was my dad calling her that broke the moment and it seemed very reluctantly she walked out of my room. Luckily or otherwise for me, it was raining the next day and my dad went with her.

Now the real hint if I needed one. Only last week with my dad away for the whole day, I definitely heard kate masturbating in their room. Twenty minutes later after I'd returned to my room, getting a drink from the kitchen, I saw a pair of her panties on my pillow. They were moist in the pussy area and it was obvious she'd used them to clean herself up from her noisy masturbation. If it wasn't for my friend calling by, well I genuinely don't know what I would have done or what would have happened.

So I have a few questions. Is my step mom giving the big come on, and if she is, should I oblige her ?? If not, why did she leave the panties and why does she look at me with what I know to be longing eyes ??

She is one fine looking woman with a wonderful body and she does turn me on, but after all she is my dads wife and I know he loves her in his won way.
