You don't look like you can take to much more.
Lets slow things down a bit.
Give me 50 slow strokes, 50 fast stroke, and then 50 more slow strokes.
See wasn't that easy?
Now 100 fast strokes and use the brush on your thighs and balls again.
Stop and tickle the head of your cock with the brush for 1 minute.
Ready for more now that you rested some?
