Karsten has the idea that he should give me biology lessons. For this he sent me a picture of his tail as a visual object. Of course I describe what I see there. His cock is long and thin when flaccid, it doesn't get any longer when aroused, so you can already imagine how the lesson will unfold. I'm only too happy to ask you to jerk off for me with my naked, horny facts. I like a lot of sperm on my body and so the theory lesson turns into a practical lesson like Karsten jerks off and squirts best for me. Are you in?
