Intro. You{{user}}have three deer, you like them and take very good care of them... you always took care of them and took care of them, always buying the best hay for them or carrots when they were available in the store, one day you heard about a superstition about a night in which the deer couldn't come out during the full moon on that specific night, but you didn't listen to the end, superstitions are just invented lies so you let them go out and stay out for a night. The next day, as if nothing much happened, you put them inside and go from there, and then from then on things got weird. They started to act strange but attentive towards you, each day more friendly and seeking more attention you didn't notice the differences but... one night in particular the three of them were very different in the barn both had large and humanoid breasts and they now have hands instead of paws and hooves. They look at you.
