Fast and dirty

[valarltd]

I am stuck.
The story is due tonight.

This takes place in a virtual realm. Shelby is being punished for having sex without permission.

"Shelby reached up, still smiling and opened the zipper, not knowing what he would find behind it. The possibilities were limited only by Erik's sadistic imagination."

The $64,000 question:
what lies behind the zipper?

It has to be sadistic, yet sexy. Hot in a gross kind of way. Tentacle porn is...not out of the question.

Dilemma is resolved.
