The nearly naked ape man brushes his big toe against your leathery finger, and bears his teeth. You're not sure if he's smiling or not.
His fingers disappear into the leather loincloth, and he extracts a small phial from the pouch. Apparently, the leather functions as a pocket as well as a jockstrap. Unbidden, a stupdi joke about family jewels sneaks into your mind. You snicker, which sounds oddly like, "Oook, ook."
"OO-oo-ga-ook!" says Tarzan. Images form in your mind, as he empties the phial of liquid on to your face. It trickles through your open mouth and into one of your nostrils. You understand what Tarzan said, but it cannot be true. Your ape body tingles, it's changing, the phial worked! Tarzan fingers his lasso, as you feel your body quivering under your fur.
