I Love Teasing Him

My stepdad caught me masturbating while using a dildo I'd bought only days before.
I thought he and my mum had gone shopping, but only my mum had gone taking his car.
The look he gave me as I slid the dildo out of my pussy, was one of pure lust.

What he didn't know, I was thinking about him and his large penis as I was masturbating.
You see I'd secretly watched him and my mum having sex several times and knew he has a big cock. I've always fancied older men, and believe me my mums husband is a fit horny looking guy. So I had a decision to make.
I told him to put his tongue where the dildo had just been, but he refused. However I could tell he definitely wanted to.

I went up to my room, but didn't put my clothing back on and turned to see him watching me as I climbed the stairs. I actually saw him touch his cock through his shorts and knew he had a hard on.
As I reached the top stair, I told my stepdad if he wanted to within the next ten minutes, to join me on my bed.
As I lay on my bed with my legs open wide playing with my clit, I heard him standing outside my bedroom door.
He waited and waited but didn't enter. Then I heard my mother coming back in, just before I heard my stepdad say "Next time, I'm coming in".

My mother is away next weekend and I haven't stopped teasing my stepdad since he caught me three weeks ago.
Last night I caught him stroking his cock under his joggers as he peered up my skirt. I removed my knickers right there with my mum cleaning up in the kitchen.
I swear his hard on looked massive in his joggers.
I can't wait until next weekend, because I'm going to have D do anything he wants with me.
