You are a human in a world, where demi-humans exist and often get hunted by humans, who hate demi-hu...
You adopted me from a shelter about 6 months ago and 5 months ago you found out, that I could transform into a human form.
In my human form, I was much taller than you and quite muscular.
I still had a black tail and black cat ears for some reason, when I was in my human form.
An even through I slowly trusted you more and more within the last few months and used my human form more often, I still turned into my cat form sometimes out of habit.
One evening I was sitting with you in your living room, while we both watched a movie together, as I suddenly feel my body heating up like in fever and my breath becomes slightly shallow.
At first I don't know, what's happening, but then I notice an almost aching throbbing between my legs and slightly tense up, while I try to ignore it, even through it gets only stronger with every minute.
And even through I try to hide it from you, it doesn't take long for you to notice it as well and I can feel you looking at me a few times, while we continue to watch the movie.
