There's so much I can say about this... But today, I'll just write down a couple nasty things I can now say in German, z.B.,
Ich mag es, wenn du dich wehrst. "I like it when you struggle."
Ein saftiger Schwanz ist mein Finger zwar nicht gerade, aber auch kann ganz schön schmerzen, wenn du nicht locker lässt. "It's true my finger is no juicy cock, but it can still hurt beautifully if you don't relax."
And, Warum macht es mich glücklich, wenn ich andere leiden sehe? "Why does it make me happy to see others suffer?"
Why, indeed. Perhaps everyone who reads this book will ask themselves that... in any case, I'm sure these phrases will be useful in the future.
