Intimacy disturbed by a sex slave's carelessness.

Last night Master and I had one of those moments that surpasses the master and sex slave relationship. We were in bed and Master was inside me, keeping me just at boiling point by stirring me with slow circular motions of His hips. His mouth was on mine, His tongue feathering with my tongue and my legs were wrapped around Him. I was just ready to ask Him if I could come when He changed rythym and gave me several hard thrusts which tipped me uncontrollably over the edge and earned me 50 more strokes for later today.
It must have annoyed Master more than usual because He ordered me out of bed to sleep elsewhere. I must say that I have limitless admiration for His self control as He didn't finish inside me before I got out of bed and it surely left Him as frustrated as He was cross with me. But then I suppose He can have me whenever He wants me anyway.
So I departed to sleep uncomfortably on a sofa (I hate sleeping in a spare room and the living room was more inviting). However I did not sleep well and at one point I contemplated taking a whip back to the bedroom and suggesting that He gave me an on-the-spot punishment instead of banishing me from His bed. In the end I did not as I was afraid of wakening Him and angering Him further.
And just when I was thinking that I might escape lightly this afternoon. Fuck it!
