my surprising step daughter 3

I had been living with my girlfriend Judy for a few months now, and it had been about a month since I had first started fucking her teenage daughter when Judy wasn’t around.
Emma had been a virgin when I got my hands on her, but she was a quick and enthusiastic learner.
You might want to have a look at parts 1 &2 of my story to see just how enthusiastic she was, and exactly how I managed to get into her pants in the first place.
Well, if I’m honest with you, I’m no super stud. Not like the kind of guys you read about in magazines, or watch on videos. Sure, I’m reasonably good looking, and I know I have a bigger than average dick, but the days when I could fuck for hours and come back for more are sadly behind me.
I was finding it increasingly difficult to satisfy both my girlfriend Judy and her cock-hungry daughter Emma, and inevitably something had to give.
Sadly, what was ‘giving’ was Judy. The more I screwed her daughter, the less interested I was in her, and she soon realised something was wrong.
One day, I had a day off work and was at home in the lounge when the phone rang. I was beside the phone when it rang, and picked it up to find it was Judy, calling from her office.
‘hi honey’ she said, ‘it’s me’
‘Hi Judy’
‘ listen,’ she said, ‘ I’m going to be late home this evening, will you look after Emma for me when she gets in?’
‘ sure’ I said, looking down, ‘ she’s home already, but I’ll take care of her for you, when will you be back?’
Emma looked up at me from the floor, with one hand wrapped around my cock and the glistening knob of my prick running across her lips, she smiled mischievously.
‘you want me to give her something to eat?’ I asked
‘oh, that would be great’ said Judy, ‘you sure you don’t mind?
‘not at all,’ I replied, as I slipped my cock into her daughter’s ready mouth.
Slowly, but steadily, I fucked Emma’s mouth as the conversation with her Mom went on.
Emma knew well who I was talking to, and it was really making her hot.
Here she was, sucking her Mom’s boyfriend’s dick, as she was talking to him on the phone!
She began to fiddle with one hand at her trousers and, incredibly, managed to slip them down without taking my cock from her mouth.
I carried on chatting away to Judy as she began to finger herself.
