I've been trying to find this comic for a few years now. I deleted it for some stupid reason. I'll try and describe it.
A wolf/dog/canine of some kind gets in a car crash, some native cow chick heals him through coitus and when he gets too greedy she curses him with the inability to stop cumming
I don't know if we're allowed to make these kinda threads but... too late
I'll post some stuff in the meantime I guess
