okay, I have an idea for a video that I've been playing arou.. (OnlyFans)

okay, I have an idea for a video that I've been playing around with, but I can't quite figure it all out. I have 3 of the same dildo in different sizes, so the plan was that my cock just keeps growing and growing... and then what? what do I do with the giant cock? should I make it a pegging roleplay video and it keeps getting bigger as I peg you? orr??? Idk, I'm just looking for ideas so if you have one I'd love to hear it!
