A detached head would be good for your own oral gratification for it is not limited in movement by a neck.
there was this sick/twisted horror movie from the 70s/80s that had this guy who had his head removed, give a tied down naked chick, head....... so the head was giving head.... it was quite strange, and I wish I could remember the name of it.
ahh I think it was called the Re-animator, about a scientist who discovers a serum that could re-animate life into dead things, so there were zombies all over the place... and yeah, a guy who had his head detached from his body was holding his head, and giving a naked chick head. it was bizarre and perverse. and a first in film history.
that would stop traffic for two reasons:1-too big, cause accidents2-ITS A FRIGGIN HEAD ppl would b rubber necking to seee that thing hehe
