I'm not really into necro. But... I like that idea of "arranging" the body a bit to tell a story.

When the police finds her, they will find her just as motionless and dead as I found her, but she's going to have a finger in her anus while her lolling tongue is still resting on her clit as if she had been giving it a lick just as she finally died.

Her other hand will be perpetually clenched into her own breast, as if she just had an orgasm in her last moment, while playing with her own corpse.

Maybe take a pic of her as I leave and make sure it gets viral on the net!
