You only think about it for a moment, the decision made almost before Ms. Yannatou finishes speaking. Who would ever want to go back to being a boring human boy when you can spend the rest of your life as a satyr? You grin at the boy still embracing you and say "If I have sex with anyone?" The boy flushes, but grins back and presses harder against you.
"Yes." Ms. Yannatou shakes her head. "And it looks like you will continue to provide a good demonstration of the class."
You tug at the boy's shirt and he fumbles with his belt. In less than 30 seconds both of you are naked and embracing in front of the classroom, the kids all wide-eyed as your rigid goat cock begins to probe the backside of the boy who had been holding you. He gasps as you thrust in, and your arms circle his chest to hold him tight against you. The pleasure is intense, and your mind focuses on the sex. Sensations are intense, the physical pressure of his anus, the smell of his sweat, your own musk, the heavy weight of your goat-like testicles swinging as you mount the boy. You can feel things settling in place within your mind, the changes of your body becoming set, permanent. Being a satyr feels normal to you, and as you shudder in a sudden release and jet into the boy, you cannot remember how it felt to be anything else. You bleat the boy cries out as your final thrusts fill him with hot, thick seed.
