Cum inside her!

You can't hold it in any longer, and begin spurting into her pussy with a roar. You cum for what feels like a minute, as Yoko quakes and coos under you, her pussy convulsing around your dick as she cums with you.

Exhausted, you pull out, and watch as Yoko, without being asked, gets up and starts to lick your cock clean. She starts from the head, with short, quick licks, moving down with longer, more thorough licks towards the base and balls, and finally, once she's sure that your tool is completely clean, gives its head a little kiss.

Yoko looks up at you, and says, "Did you like that, Master?"

"Hell yes," you say, "And I want you to do that again in the future..."

She smiles cheerily. "Your wish is my command, Master."
