This has been a gradual process but recently we crossed this milestone. It started with occasional periods of orgasm denial. We noticed the pattern any chastity sub gets familiar with. After a week or two of denial, your attitude shifts. You get addicted to that arousal and you want it more and more.
I'm a 30yo Male sub who believes Mature Dominant women are to be worshipped and praised and most of all obeyed. Especially Wives Mothers Sisters and Aunts. I find I can have much more intense orgasms this way. Physically, this feels better in me then his cock ever did. Mentally, the look in his eyes as I fuck his face, while his cock remains locked up and untouched, puts me over the edge every time. Nor could our relationship be stronger. Some may say this is cruel, but he has no one to blame but himself.
