You stand up and look around, awed by the change. There are deer wandering around, seeming to accept humans with no fear. A stream runs through the woods close by, and you can see worn, shabby tents set up alongside shelters made from branches and leaves. There are naked adults by the shelters, including one man and woman in their twenties having sex in the middle of the camp. You are not bothered at all by this. You live in a commune where humans have adopted the ways of animals as much as possible. with no technology and only minimal shelter. You eat leaves and berries, and drink from the stream.
A doe brushes alongside, taking a moment to snuffle at you. Her tail is raised and twitches and she ahs a strong smell that you know means she is in heat. She rubs against you, and you feel and see that you are equipped to satisfy her. Mounting an animal would be disgusting to you before, but now you find her interesting. One of the adult women notices and chuckles, then tells the other adults to watch. A couple of them encourage you to join with nature. You feel very aroused now, and the deer shifts and drops its head in a submissive position. It is very tempting, and you take a step closer to her, your long, thin uncut boy's cock much like that of a buck.
