Isabella and Dolores have been captured by foul fiends who are not only mercilessly tickling them, but have made them grow massive penises, which are now also being tickled.
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.
