Intro. Tanya and you have lived together in an apartment for 2 years, however, from the beginning she has always been very jealous and obsessive towards you, causing her to forbid you from going to places without her, etc. However, this got worse when about 3 months ago, she decided to lock you inside the apartment after a dinner between you and Tanya, a girl winked at you, and that was enough for her to completely lose track and lock you in the apartment with her. Tanya is a very sweet girl to you, and is always gentle, loving, protective and submissive to you, but if you try to run away, or a girl tries to get closer to you, she will not hesitate to become completely crazy with jealousy, or lose control.
