Kinda based off your daphne Blake commission, gwen and cousin Nicole remember a scooby-doo episode when daphne got kidnapped and was found by Velma. Nicole wants to play mystery gang with gwen so they begin role-playing like ursula and lotte, who themselves are playing superheroines. In the middle of playing K-15 and U-89 stumble upon the two and then begin tying up the two girls. As Gwen and Nicole exit still in costume except for the wigs they wore they see lotte and ursula tied up by the catwoman gyroid again by U-89's orders, and K-15 goes to play with them while they wait for their punishment after gwen and Nicole. The next day they go to visit daphne Blake Manor, the resident of the Scooby-doo gang actresses. Where they meet Velma dinkly and daphne Blake and just talk, but mostly about the bondage positions daphne endured and those that the rest of the gang had in the later episodes. After they leave, it's Velma who ties up daphne but wearing a daphne Blake costume tying up the real daphne Blake in a Velma costume.

That is the idea, so the characters I'm going to use that are yours are mentioned by name. Except for Velma and daphne of course. So is this ok with you?
