You wander around the zoo, sometimes joining other little kids at hands-on exhibits and a couple of petting areas. As the sun goes down, you hear announcements that the zoo is closing. Where can you go? You really don't want to leave. No one seems to notice you - it is strange that you have been wandering around as a naked three year-old all day and no one asked where your mommy was. You wonder about going back to the fountain, but getting younger is a bad idea. Besides, the man and his friends may be looking out for you.
There is a snort, and you look over to see a huge black gorilla pressed against the bars of its enclosure, one arm stretched out through the bars toward you. It grunts again, obviously trying to get your attention. Curious, you go over and stare up at the massive ape. It is watching you with large brown eyes that look very intelligent and caring. It strains, trying to touch you, but you are just a little too far away. You feel no threat from the beast, and move closer, almost to the outer fence. This allows the wrinkled black fingers to brush your face gently. It is a female. You see her breasts, and also sense it. Her touch is pleasant, and you step even closer, letting her feel your face and head. The thick fingers slide over your face, your ears, all over your head, pushing into your mouth, feeling every inch. When you reach up to touch her hand, she takes it in hers and holds it easily. You feel very strange, and her scent is both familiar and welcoming. She lets your hand go and stretches out her arm to rub the top of your head again.
You catch site of the hand she was holding and stare. It is brown and wrinkled and covered with black hair on the back. Gasping, you feel your face. It protrudes out, rounded and covered with soft fur, your nose little more than a slightly raised pair of openings. She is turning you into baby gorilla!
