Looking for an old story

[Sandy Place]

I don't remember the character's names - there was a woman (on horeseback?) who encounters (or tricks) the male character into quicksand and she compels him to satisfy her carnal desires orally before he goes under.
IIRC, someone added a drawing (or two?) to the story. I think.

I hope this is enough to jog someone with better recall than I posses.

Cheers.
