Yes, the disappointment is always the worst. If he is an experienced dom - or even if he is just learning but has read up on this stuff - he will not be surprised. One thing about being a sub - you are learning; and he is teaching you.

It is early days. He may or may not punish you at all - other than to express his displeasure.

But you should tell him. Absolutely, tell him. Open communication, trust: again and again you will hear these as the fundamentals. Do you keep a journal? Do you email him? I'd tell him sooner rather than later, you know. Not telling him is compounding the error.

Oh - and CR, OD - teasing and denial - it is HARD! We all fail some time or another - really it is not just you; and we all rebel, and do things because we want that reaction - we are testing our ground. Read the orgasm control threads - they're good for learning, they're good for a laugh.

Oh - and - just 'cos you stopped - does that mean you can't start again? Show him you're trying?
