BAD IDEA
Does it hurt more to get hit by the cousin's big dick or the big cousin's dick?
Neither situation sounds like a good idea unless you enjoy family drama and pain.
This question dances on the border of questionable family scenarios and anatomy jokes. Either way, pain levels in situations described depend less on phrasing and more on context, and both sound like a recipe for regret. But hey, if you’re asking, maybe consider keeping family reunions drama-free and exploring safer hobbies.
