A few years ago my girlfriend lived with her parents and her older sister was still living there too.

There would be evenings where I'd stay over and stay until the afternoon if I had a day off work the following day. Most of these occasions her family would be at work and every now and again my girlfriend would be at work too.

This meant I had a bit of freedom around the house and could have the morning to myself.

One day the perfect opportunity presented itself. I was all alone. I was in my late teens around this time and the first thing that crossed my mind (probably still would today) was to take freedom to the next level and wear my birthday suit.

I wondered around the house a bit, but only upstairs as it was too risky downstairs because I'd someone came in I'd either be stuck in a room or in plain sight without a route for escape.

After feeling proud, I started to get a bit hard and turned on. So I made my way back to my girlfriend's bedroom, shut the door and got my laptop out for viewing pleasure.

Now, picture this; a young guy completely nude, hard as a rock, slowly stroking away with some porn playing on a laptop (I always have it on mute).

I was a bit sloppy that morning as it was something I've always been looking forward to doing but never had the chance. It completely slipped my mind that her sister started work in the early afternoons... Oops!

She woke up (with me being oblivious to it) and, must have very quietly, come out of her room to get her morning cereal...

But, before doing so she must have wanted to borrow something of her sisters (my girlfriend) because she opened the bedroom door only to find me spread out on top of the bed covers stroking away, and, within a moment's notice embarrassingly covering up looking like a deer being caught in headlights.

She never did complete her mission to retrieve what she wanted from that room, she only left with an eyeful. Admittedly, she did look for one second longer than I expected before closing the door but it's never been spoken about since.

I wonder what she thought, and does she still think about it?
