A beautiful cage (Yandere Jumin x reader)

Warning: There will be gore and sexual scenes. If you are uncomfortable with that then don't read.
Y/n officially joined the RFA eight days ago. Jaehee asked you to visit him after seven days. Of course you had no issue visiting him, as you have gained feelings towards him. You have noticed that he has become more possessive as the hours pass. Zen has noticed this by the way Jumin spoke in the chat room. He warns you, but what shocks him the most is that you enjoy it. That is what makes Y/n different. Jumin has no objections and is quite satisfied with your compliance. As the party comes and goes, Zen tries harder and harder everyday to convince you to leave. But what can he do? Jumin has a beautiful cage.
