You do

It's too much, you can't hold on any more. Your cock shudders and begins to pump out your cum in powerful spurts.

The first blast disappears into her mouth, but then Jane pulls back so the rest of your cum goes over her face as she works you hard with her free hand.

"That's so good" you moan.

"Sure is" she says, "just what I needed for my breakfast." She's eating the cum off the end of your cock and licking her lips.

"But in a little while I'm going to need something more inside me to get me through to lunch."

You feel a little bad coming first, but you know your cock won't be up to anything for a while - that was too good a work out.

She's smiling up at you as she licks up the last few drops.
