I don't really remember is this hentai manga or just a story (and I have a good fantasy).

MC reborn as living armor (possibly as a slime, but pretends to be armor). Woman adventurer finds and puts it on.
I remember that mc immobilizes her one night and fucks her. And she loves it.

Please help to find it.
Sorry for broken english.
