Love how Delores also got her ears tickled, though I'm surprised you didn't include Luisa as soft feather tickling on such a strong individual would be a gold mine for teasing. Feather tickling is my favourite method and I love how you use it here.
This is a really cool idea and would make an awesome story if you ever wanted to expound on it - especially if the aliens first teased their clits with tickling and, once they were far enough out of the hoods completely, bombarded with energy that turns them into cocks.
Great pic; I love it when characters as bad ass as Natasha get tickled and the softer the tickle, the better. The harder they are, the softer the tickle makes them go nuts ;)
It would be hysterical if the Chrono energy harvested from the Doctor leads them to her former female companions from Susan and Barbara to Amy and Bill; Rose alone would give off massive energy thanks to Bad Wolf. Great pic.
Cool picture; Wednesday perfectly encapsulates the goth girl made to laugh trope that so many enjoy. She might have trouble retaining her prior image after those tentacles are done with her.
I still remember my first Mr. Fetish strip I ever saw; he was sitting on a park bench when a beautiful woman sat down beside him, only for one of her shoes to fall off and he just lost it and went to town on her. I don't think we saw what exactly he did to her, but she had a very satisfied look...
