[Gold+ Tier] December Poll: Christmas Sausage (Patreon)

My first male-oriented poll! I've drawn male characters here and there, but never finished any of them. I have these 4 pics of slender-but-generously-endowed boyos up to flats, though. Which pic should I finish first? I'll also give the winner a stocking stuffer "censored" alt in time for the holidays.
