Like Father, Like Son.

Just over two years ago my husband passed away. He was a man who kept me sexually fulfilled, so I struggled without his love and attention.
Eventually I bought myself a couple of dildos to enjoy time alone and it's because of this I'm here.
Five weeks ago I was having a great time plunging one of my dildos in and out of my pussy and arsehole.
I'd totally stripped off knowing my son was at college and was really getting into fucking myself.
I'd closed my eyes and must have been moaning, because when I opened them having just orgasmed, I was looking up at my son stood only feet away.
He was looking right at my pussy and the dildo poking out, and he had his cock out.
I don't know how long he'd been stood there, but it was obviously enough to become erect and decide to masturbate to his own mother pleasuring herself.
Right as I went to say something, he jerked his cock and came all over the floor in front of him.
Not really able to say anything else, I said "I think we'd better clean up".
It was a bit awkward later on but my son was totally cool about everything, even saying it was good to see me enjoying myself.
I let him know it was wrong for him to be watching me and wanking. And his response was "Why, you're a beautiful woman and I'd definitely fuck you".
Since then we've skirted around what happened and what he said, but these past few days my son has openly been masturbating so I could find him doing it.
It's getting harder and harder to resist, especially when he said the other day "I am going to fuck you mum".
This coming weekend we're travelling to a place my husband and I used to visit. I genuinely tried to book separate rooms, but there wasn't any available. So my son and I will be sleeping in the same room.
He's already told me he can't wait and said this "You won't need your dildos this weekend".
As you can probably imagine, my son in every way is the image of his dad, right down to the size, girth and curved shape of his cock.
I know I shouldn't be thinking this way, yet I also know every part of my sexual self wants sex at the weekend.
