This story is set several years after part one, maybe not seven years as it is in reality, but still a good while!
It wasn’t until about three weeks before my 39th birthday that I realised that if Mistress Karen didn’t let me cum beforehand, then I was going to hit exactly one hundred days of chastity on the actual day. I knew then that something was up and that this couldn’t just be a happy coincidence. Could it?
Of course she never told me she was aiming for my birthday, she just kept ruining me every so often and teasing that she wanted me to wait 'a little bit longer' and since she has been controlling my orgasms for quite a while now, all I could do was wait and see...
I awoke quite early on the morning of my birthday, which luckily was a Sunday (so no need to rush out of bed and get ready for work). As usual my cock was hard and aching for attention, so much so that I could even feel some pre-cum lubricating the tip.
I rolled onto my side and cuddled against Mistress Karen’s back, my swollen tool pressing eagerly against her gorgeous ass, while my hand slid over her side and up towards her heavy breasts. Mistress continued to doze, but slowly ground her sexy ass against me, increasing my already pretty intense level of desperation.
I grunted pleasurably. This was exactly what I signed up for after all, when I gave my wonderful wife complete and total control of my orgasms, and this was what I got. I certainly wouldn't change it for anything...
Eventually Mistress reached back and cupped my swollen balls.
"Mmm," she said, "these feel so full of cum, I bet you can't wait to empty them?"
I groaned in agreement as she turned over and faced me.
"You know what today is, don't you?"
"My birthday..."
"Yes, but that's not all. Do you remember ages ago when I was teasing you and I said I should get you to a hundred days and then... well, do you remember what I said I should do once I got you there?"
