Self-Slapping Session: Rough Tit Slaps

Even though I am very much a lover of everything rough and I thoroughly enjoy slapping and impact play - my tits are the one area that are always really, really sensitive. But I really want to become a proper pain slut and really build up my tenacity to the point where I'll be able to use staples and the like as a means for pleasure on my boobs... So the best way to start? Some rough tit slapping, done by my own hand. I didn't stop until my boobs were completely red and sore, and I dare say I did quite a good job!
