Our slave hopeful was attempting to serve but will he be able to take all we dish out??

We experiment with his nipples at first. His pain threshold is very low. We move on to the cbt. We insert sounds in his urethra and watch his reactions. Hes a big wimp. We move on to teasing and face sitting. He fails every test until we decided it was time to throw him over the edge and make him bust a huge load all over himself.
