Having a shower with the boss!

I am a teacher and really fancy the headteacher that I've worked with for a few years now   I think he feels the same because whenever we have a meeting, we sit on desks opposite each other and have got into the habit of leaning backwards on our arms giving each other an uninhibited view of each other's crotch!
He likes to wear cropped trousers in the summer and they all seem to be a little too small, making his package obvious which he always seems to tuck down his left hand trouser leg - I'm not sure if he wears boxers - or no underwear at all but he seems to like giving me a show!!   He's younger than me by the way - about 15 years younger...
I'd never seen him naked until a few weeks ago when we took a class swimming - we shared the teachers''changing room.
After the swimming session we both shared the small communal shower in the corner of the teachers room!  We didn't say a word but immediately started soaping up each other's body - he was the first to make a move on my cock but I soon joined in.   We only had five minutes because we had to take the class back to school! It was the most exciting five minutes of my life and both shot our loads as we squeezed each other's cock - pulling ourselves towards each other!
Can't wait - cause in a few weeks time we are going to a residential conference - and we'll be sharing a room for two nights !
