Get back on your knees and stroke to the beat. Does it make you feel emasculated to be told what to do by your girlfriend? Does it make you feel like a child to be whooped on the ass for misbehaving?
You should feel these ways, because I am simply making you feel how you really are. No real man would cheat on his girlfriend. And thinking you can do what you want, and expecting everything to be normal afterwards, is childish.
So therefore, you are a boy, not a man, and I must treat you like a boy. Do you understand, boy?
