You mean like skewering? Hmm, I could consider it.
Happy to hear you're enjoying Cassie! She seems to be many people's favourite
OH! Nonono... not... not quite that. Skewering implies uh... a rather unpleasant time, actually. All the way through typically implies just going through the digestive tract without puncturing it. In one end, out the other, but no gore and blood and all that. I didn't mean to imply that, if I did...
Just got through some of Rinny's content, and I'm pretty sure she actually suggests it with her tail anal scene, lol. That, and any scene where you add climax overload might be ways you could add it in as well. The succubi seem like the types to perhaps have that option with their body modification stuff.
