Relight my fire

I’m a 46 yo single mom of 2 children, I’ve not had sex for over 3 years now, I don’t masturbate much and being honest I don’t really get any urge for anything sexual.
But! When I’m upstairs watching my neighbour 2 gardens away walking about in his boxer shorts I do wish someone like him was between my legs, I get myself all worked up thinking about that young man pleasing himself with me.
