A: Lick her pussy through the panties (3 points)
Alright, with panties on licking the pussy might be allowed, but only because it's so embarassing to watch!
B: Lick her elbows (0 points)
This is nor humiliating nor fun... just... stupid, in this case
C: Suck her high heels (5 points)
Of course best reward is for the all-training cock sucking machine
