Not sure how you'd do just the boobs with a spit roast other then simply having the spit roast with her boobs over a small fire which kinda seems like that's kinda the only way yah could do it. I mean a spit roast is kinda a pinned in place body… there's not much else you can do with it. that's why i don;t understand the question ^^: its kinda like "hey any ideas how to do fire, but not use fire?"
