It's a fine line you "walk" as a Fluffer!
You want to excite and entice him but not too much!
You want him to think about cumming, but not with you!
You want him to enjoy your hot sucking mouth, but only a little!
Sometimes though, despite your best intentions, you push things a little too far and his instincts take over!
Hopefully you can get him hard again quickly because she doesn't like to wait!!!
