Golden Rule...

Mark's POV:

The moment Anna gave permission to give punishment to her, I didn't wait for one more second and went to my treasures and started enjoying them. Actually, she is scared by listening to me when I am saying about BDSM techniques. 

Even though she is scared, she asked me openly to give her the punishment and I take an active part to show how BDSM pleasure works intensely, so that her fears and doubts get clear...

The moment I entered under her shirt, I didn't directly bite on her boob. The things in the BDSM should be in a slow phase so the submissive won't get hurt and enjoy the pleasure I gave to her...
