Well....I left my sub's tits marked in more ways than one.  When I was all done, she had rope burns on her tits, bruising and raised welts from the application of the bamboo cane and I came all over her tightly bound tits.  

 I fisted her, fucked her from behind, fucked her with a large rubber lifelike cock, made her suck my nuts and all in all, just used and abused her.
