This is the $190 Krang belt buckle made and sold by Etsy member ChristopherGenovese. That would look awesome on my pants. Hell, that would look awesome even if I wasn't wearing pants. Or underwear. Just Krang hanging out steering my penis. Make it rise! I sense a homemade Ninja Turtle themed p0rno in my future. "Solo?" Just me and Krang!
Keep going for shots from different angles.
Thanks to lilco, who informed me Ninja Turtle themed p0rnos already exist and they are not for the faint of heart.
