Holy shit! Talk about the right place at the right time!!
She starts to spray herself with he hose and your cock is now at full capacity.
Looking around, no one can see you. There is nothing left to do but stick your hand down your pants and start stroking your cum lubed cock still in the condom.
This is every mans fantasy, your not going anywhere and chance missing something hot! You are crouched down to make sure she doesnt see you and start rubbing your cock.
