Adventure style tease, quite long and complex. Very challenging to do in 1 sitting, but can be "saved" and come back to later. More information in the forum.

You find yourself in a compromising situation, one that will take you all night to get out of. Tease will be challenging to complete in one sitting, but you can continue at any time without needing to start from beginning.

You go head to head with some tough ladies! Very long and challenging tease, not intended for one sitting. Please see "Mercy, some thoughts" for commentary.

All of them by Decker, because I don't know another LONG teases of good quality.

The Bermuda Triangle series is another good one.
