I always think it would be an enticing scenario to play out for rp. In fantasy, having someone just want you for how fat and soft you can grow under their influence is amazing. In reality though, I imagine that would both be immensely problematic and hurt like a bitch since the kidnapper likely wouldn't care how your (kidnappee) body was being affected. Still, something to think about in a comfortable and pre-discussed bedplay rp maybe.
Yes, I would just add that this has potential to be like "quest-rooms" but fetish-oriented. Because it would be very cool place for intimate/public stuffing
