Three years ago my then 14 year old step son Alex caught me masturbating using a dildo on our bed. He asked me why I needed to use it as I was married to his father. I sought of lied and told him, it was because I get horny sometimes when his father worked away. The truth was his father could no longer satisfy me enough for me to feel sexually fulfilled.

Now three years on, it was my turn to catch him stroking his cock. The difference was he was using a pair of my panties to masturbate to, sniffing them as he whacked off. And what a cock he was stroking. It was huge and looked so hard and full of pulsating veins. I had trouble not to just leap on his bed and take his massive cock into my mouth, but I did resist, but not before telling him I thought he and his cock looked beautiful.

This last two weeks I've been masturbating privately, then leaving my panties in his room. I know he knows I do it for him, as he puts them in the wash basket full of his semen afterwards. I can't help myself and know if he asked for sex, which I dearly hope he does, I'll allow him to fuck me.

It's just a matter of letting him know its ok to ask.
