Kevin enjoys his hike up a small mountain and finds a lake and waterfall. Deciding to take a break to eat, he hears a woman moaning from a short distance. He quietly moves closer and discovers Penni, a futa nymph, pleasuring herself on the bank of the lake. In his amazement, he mumbles under his breath and Penni catches him watching her. She is upset that he was peeping on her and turns him into a futanari for his punishment. Kevin pleads with her to reconsider, but she demands that he take her home with him and be her futa on futa lover for three days. If he can do this for her, she’ll change him back into a man.
