Daniel,
 
Our ferrets Lexus and Princess both groom us like you described.  Lexus
is the worse.  She licks you, usually on the arm, then gnaws.  Sometimes
she'll bite fairly hard.  Princess licks and then just bites!  Don't know
if that's grooming or not.

safely in a well preserved body, but rather
to skid in sideways, totally worn out, shouting
"... holy s**t... what a ride!"
