Cum instantly.

You are amazed, and in pain, at the size of the load you just blew in your hand. It was so big that it looked like a comical bubble that made two of the four inches noticeably bigger in diameter until it exploded out the bellend of your rapidly, nevermind that instantly softened cock. The hot pornslut let out a low but sweet(?) laugh and said "Hopefully there's enough left to make me happy."

You panic and mumble "yeah, yeah. I've got whatever you, you. I'm going right now. Right after I wash..."

"Don't you dare gooner boy. Lick your hand clean...and get whatever is on "My" tiny little dicklett, now on camera or I won't meet you out in the parking lot to give you head and then bring you up to party with me and the girls" She said with an aura of authority you couldnt deny.
