I gasp and drop the growing creature onto the sand. The boy is getting older, maturing into a young teen. But his face is also pushing out, and his upper body sprouts a coat of the same thick black fur that covers his legs. He lands on his hooves, and straightens, already taller than I am.
I would guess he is about 16 already, but his features are almost fully animal now. He begins to thicken, becoming massively muscled. His sexual equipment is fully that of a bull now, with testicles like oranges and a thick, sheathed penis. A gold ring has formed in his nostrils, and his horns are at least a foot long.
He regards me with those huge eyes, and then reaches up to tug on his ring. It slides out of his nose, though I can see no opening or break, and he holds it out towards my face. I can tell he intends to press it againt my nose.
