Well, it's not like you can go home like this. Anyway, it could be really interesting. You press up against the outer barrier and reach up for the gorilla's arm. She manages to pull you up, and then shift so her hand cups your butt as she draws you carefully into the gorilla enclosure. You feel strange sensation from your rump and squirm slightly. It isn't uncomfortable, just weird. You glance down to see black fur spreading up from your rump, but more importantly, you see the small nub of your toddler's penis melt away. You wet yourself in a shock of fear, and the liquid comes out from your butt. She just turned you into a girl! Oddly, you are over the panic the next second. So what? You are becoming a baby gorilla. What difference does it make?
You are pressed against her chest, and she embraces you gently with both arms. The full contact speeds up the change, and you feel your body shrink, your arms and legs change proportions. Your mouth finds a teat, and then you are nursing. The idea sorta grosses you out, but it tastes good, and you feel safe and warm and happy. She grunts, stroking the back of your head as you nurse. You feel so sleepy.
