A runster is a cool, totally rad person who runs; for fun, fitness, weight loss - it don't matter. Long distances, short distances, slow or fast running in it's pureness.
“Material” used to enhance the enjoyment of rubbing one out. May be old fashioned porn mags, online porn, pics/images or just a good old filthy, vivid imagination aka spank bank.
I racked up an online porn Bill this month. I need to cut back on the costly rubterial and just scroll though instagram.
I used photos of the milf next door for rubterial.
