We live a very similar lifestyle. His last time to have sex was last October and his last time will be this next October. I have led him cum three times since then but that too will stop in October. I love having him dread the upcoming date, knowing his next pleasureful experience will also be his last.
Yes, our lifestyle is D/s. Yes, we live in a FLR. Yes, he is in permanent chastity. His device will not be removed.
My subbie’s in the same case. No way out. Period.
I have my reasons to do it to him, and I do it also because I can. His shaft’s not going anywhere into F pink piping again.
