Suffer Day - Hold urine
I was first controlled by the master to excrete, then i drank water continuously. i held back my urge to urinate and accepted the training and humiliation. if i didn’t perform well, the master would spank my swollen bladder. i also had to give a blowjob and beg for mercy. finally, i was tied to a chair and urinated while being tickled. it was a shameful and uncomfortable training to hold back my urination!
