I have some examples. None english: #584389 | The suffering of a female detective | 697 My best examples: #659194 | Secret Project—Travel | 32,930 #494885 | Suzuka Minase | 8,720 And some what close: #626532 | Komon to Onsen Ryokan ni Otozureru Riku… | 3,727 Even though i mentioned "trapped" it doesn't mean they got trapped there forever. Just temporarily for the sake of playing like carrying them around riskily outside, in public or straight having sex with persons in the box, suitcase,... or just using box, suitcase, other form of containers (not those big, just enough for 1-2 people fit inside) to transfer people.

I would also enjoy this tag Maybe like this? #637970 | JK Ojou-sama no Real Dasshutsu Game---C… | 8,161 Or maybe even this? #633311 | KAIKOU| Serendipitous Encounter | 6,188

It's different from "Confinement", encasement when person got trapped in a box, suitcase,... "Confinement" is when they got trapped in some place: Room, jail,... . Encasement is like a smaller branch from "Confinement"

there's already a "confinement" tag
