[M]y neighbour watches me

A few months back I decided to treat me and my wife to a hot tub.
Now the first thing you do is nude up and welcome the new addition to the family, needless to say me and the wife have made this a little bit of a habit on a nightly basis.
But trying to get my moneys worth, I’ve been getting home from work striping down and jumping straight in and then when the occasion calls for it, I’ll rub one out while watching some heigh quality porn on my phone, this has become my daily routine.
2 weeks ago I started to notice some noise and movement behind the fence. At first I thought nothing of it, but the next day it happened again and then again.
Now the fence between my house and next door is an older wooden fence with small gaps between each board, im talking finger width maybe slightly more and the hot tub is barley 6 feet from the fence.
Came home the next day, stripped down and waited, sure enough within a minute I heard the neighbours back door open. There I am bare ass standing on my back porch watching the fence.
Bingo, I see the shadow appear and I jump in the hot tub, normally the jets go on, but not today
Now my neighbour is a lady in her mid to late 40’s, long red hair, tall, slender , solid ‘c’ cups and one of the tightest ass you’ll ever see.
I prop my phone up on the side and turn the volume up just alitte more than usual. One eye on the fence, one on my phone, hand on my cock, still there.
I get into a rhythm and I allow my cock to break the surface of the water, still there. Now the thought of being watched as I jerk off gets me going, I pull myself up on the edge of the hot tub pick up my phone and slightly turn towards her, pretending to watch my phone I stroke my cock to the point of no return, I lean back a shoot a huge load of cum on my stomach and looked towards her as I stroked every last drop of cum out of my cock.
After a couple of moments I saw her disappear from the fence.
Wonder what tomorrow will bring
