Undying Lust

As the man lifted her arms and bound her wrists to the tops of the X-shaped frame with leather straps, Wendy tried to stop him. What was this? Some kind of ritual? She didn't want to be bound to the cross, but she was powerless to utter her objections, let alone break free. Kneeling behind her and pulling her feet apart, the man secured her ankles to the frame too, rendering her naked body completely defenceless. This was some kind of ritual, she was sure. Why else would she have been brought to a chamber and bound to a wooden frame? Why was he still kneeling on the floor behind her? The feel of the man's fingertips stroking her naked buttocks, Wendy gasped. Rudely parting them, confirming her suspicions, the man chuckled as her tethered body jolted and she struggled to break free.
"What's the matter, my dear?" he asked her, focusing on the tightly-closed ring of her anus...

A near-death experience leaves Wendy Sherman noticeably changed. She had always been very straight-laced, but now she thinks nothing of discussing sex in an open and free manner. Things go from bad to worse when she tries to lure her brother-in-law into bed.

Is it possible that in the few moments she was near death, her soul left her body and someone else quietly slipped in? Does some sex-crazed deviant from the dark and distant past, someone who wants to use her body for his own lascivious pleasure, now possess her?
