Pantyhose encasement

And here is one more account with nice encasement content

... it turned out that I'm aeady a subscriber 😆

After reading through the comments in that account, I start to suspect that it is a guy inside all those pantyhose.
Though he has some padding and corset, he still has nice silhouette.

you are likely aeady following them because they have stated that the account used to be Nylon Cherry's, a model who for various reasons has now retired. They state as much on their first tweet, although they don't name Nylon Cherry specifically and leave it as more of a "those who know know"
