When I was younger my best mate was Stuart, and he had a sister called Stephanie, she was 18 years old and a quiet sort, she was thin and pretty, with brown hair and hazel eyes that would look down at the ground or to the walls when talking to you, a shyness that would never allow her to make eye contact. I had often thought of her in ways other than a friend's sister, but I knew that nothing could really happen...
I was round Stuarts house helping him to decorate his bedroom; his bedroom was joined to his sisters by a doorframe that had been partitioned by a loose piece of board to give each other some privacy. I was aware of Stephanie being in her room with a friend, but acted bored by their giggles and laughter coming through the partition.
We were working on the room when Stuart said he was going out to the local DIY shop to get more paint and could I stay here to keep an eye on the girls as they were always causing trouble left on their on.
I knew he was going to be gone at least an hour and thought nothing more than wanting to get on and finish the job so I could go home.
I didn't notice that the giggling next door had stopped and been replaced by low voices until a head came round the partition, it was Christine, she was Stephanie's best friend, same age but a lot more forward. She was of similar build but had blonde hair. She asked if I was busy and if I would come into Stephanie's bedroom for a few minutes.
I wandered into Stephanie's bedroom and they were both stood there looking like they had done something wrong, shuffling from foot to foot, looking at each other and waiting for the other one to speak first.
'Well?' I asked, 'what can I do for you ladies?'
Christine spoke first; she had a smile on her face and looked at Stephanie who was going redder by the minute. 'Well we have been talking and, well, Stephanie here has never seen a man naked and she does not believe me when I tell her that men's willy's can get long and hard and what you do with them when they are like that'
I was speechless; these two young girls were looking at me like I was supposed to answer that statement with some kind of sensible reply. I felt my heart racing, but also my cock was beginning to stir.
'I can't talk to you about this' I stumbled over my words 'it is not really appropriate'
'We need someone older that we can trust' said Christine 'please'
Now I was beginning to get my grip back on the situation, after the initial surprise.
'Ok, but lets be quick Stuart will be back any minute' I knew this wasn't true but at that moment I needed a good excuse to get away from a very awkward situation. 'What can I say that will help you understand?' I asked Stephanie
She just looked at the ground and went scarlet in the face.
'It's not so much what you could say as what you could do' said Christine 'We both think that you are ok looking and were thinking that if you could show us what a man's bits do then we would have a better understanding than the useless books and talks that school give us.'
Strike two; I was thrown again, normally in control and unshakable, here were two teenage girls knocking me over with their forward attitude.
'Show you? What drop my trousers here and explain how it all works?' I said it in a repulsed manner, but my cock was definitely on the move and the devil in me was beginning to see some distinct possibilities for the outcome of the next hour.
The girls went quiet, even Christine with her normal brashness went on the shy side, I realised that I had made myself sound too insulted and that I needed to save something from this if anything was going to happen.
'Ok girls, I am sorry, I understand how brave you were asking this, and that it must mean a lot to you, so how did you want me to start?'
They both looked at each other with horror, they obviously had not expected this to work, or had any idea of what it might entail.
'Well, well, I said that men put their bits inside girls and that, the, urm' Christine's voice trailed away, I definitely had control of the situation back on my side.
'That is right, but first the man has to get an erection' I sounded like a sex education video, more direct action was needed, and the erection part was not going to be a problem.
I took a couple of paces forwards and stood within reach of the two girls, their eyes were fixed on mine, both mouths hanging slightly, unsure of what should be said in a situation like this.
I pulled my T-shirt off over my head and kicked my trainers off, then I unbuckled my jeans and let them drop to the floor, my cock was pushing straight out, making a tent with my boxer shorts.
The girls looked down and neither moved nor breathed, I had a captive audience and I was loving it.
