Quite often got this after a thrashing from my old man (back in the day) - I wanted fucked and there were guys who wanted to fuck a freshly whipped guy - getting beat by the old man made me mad horny!!!!
That happens to me every time after I've been punished. Usually I'm tired over a sawhorse or a tie to a bed. Most of the time my master doesn't use lube rams my ass dry for more punishment
