Leg or foot? Regardless, try placing her on her back, undress her fully, raise legs up into missionary and then lick thigh or foot (to lick foot you need to click "footjob" label that appears near left side of the screen)
I meant the foot—I didn't phrase that quite right. A "footjob" button did appear, but there's only one, on the left; when I press it, I start licking the right foot. There’s no other button visible, and I couldn't find a way to switch which foot I'm licking. Thanks for the quick reply anyway!
