Chastity and orgasm denial discussion

Since 2003 I’ve done my utmost to remain a loyal slave to my wonderful Mistress/Wife, staying in enforced chastity throughout that period. My Mistress follows the teachings of Mistress Sutton, which means she generously grants me wanton Female orgasms roughly every fortnight. That is, only the very base of the tip is ever touched. Recently, however, she has chosen to ruin two out of her last three O’s. Even though I broke down in tears after the most recent ruined one, my Mistress remained unsympathetic. Since I enjoy about twenty-five orgasms a year, this new trend is quite troubling. Naturally, I cannot question my Mistress’s decisions or motives, and I pray to the Goddesses that she does not ruin another O and let this pattern continue; I am so afraid it might happen. Any wisdom from our Mistresses or Doms on why She might be doing this, along with advice on how I should react and behave, is greatly appreciated. Have any other subs or slaves encountered this situation, and if so, how have you managed?
