Teases that are very teasing about cumming?

[jemma1]

Like a countdown that tells you when to cum, but it suddenly stops or counts backwards etc.

I love that kind of stuff. Isabella Valentine is very good at it, you're supposed to cum when she says 'Jackpot' but by the time she actually says it she's gonna tease you with like a million different words that are similar "Ja..cket" "Ja...ck...in-the-box" "Jjjjjack" "Jacky" "Ja..smine". That's another way of doing it :p
