Atacam's Demon commission.
The black widow: .. she is a shapeshifter out to find lusty cheating people/ adulterers..she finds them, lures them in with her beauty, and just when they think they've hit the jackpot, she injects them with her poison to keep them paralyzed whilst she kills them by slowly devouring their flesh; in which they feel everything up until they die. and then she drags their soul to that special place in hell for lusty folk, and tortures them for eternity..
