I can really imagine Gooctavia stuffing herself in Anon’s body and then using her gooey appendages to “fuck” him from the inside. Also that would give her the strategical advantadge of being able to control his body without giving him the chance to resist.
 
Also the added embarrasing value of having her host’s stomach full of pony goo would be exciting for her.

This fits the “wat” tag nicely, I think.
