Ghoul in the Basement - Tentacle creature gangbang.

From Create Your Own Story

You don't know what it is about giant, slimy tentacled monsters that turns you on so much, but you've gotta get some of that action. You run up to the mass of creatures and leap in.

You should know that you have six hours worth of the best, slimiest sex of your life. You should also know that no human can really sate the desires of a tentacle creature, or stand up to their rough handling. The eighteen hours after that are not so enjoyable. Finally, exhausted beyond all exhaustion, bruised beyond bruising, used beyond repair, you expire... fucked to death. Literally.
