The girl (petite, dark haired) held her sub in chastity for an entire year.
It was his birthday and he was promised to get a release on his birthday.
But they had guests over, so it's very late, just before midnight.
So he gets his release and gets a very slow handjob. Mostly teasing.
She allows him to finally shoot within a countdown, but just as he intends to finish, the clock strikes midnight and he goes back into chastity without orgasm.
Maybe by luck you can help me find this.
I just won't succeed.
