Ask her for more

Kuniko pulls you out of her mouth, and is about to turn to invite Sophie to try, when you interrupt. You've gotta at least ask.

"Kuniko, before you let Sophie try, can I ask you a favor?"

"Sure," she smiles politely at you.

"Would you see you much of my penis you can take into your mouth? I'm really craving having my penis deep inside something. If your mouth isn't big enough, I'd also be happy to go inside your pus-- your vagina. But only if that sounds interesting to you also."

She turns to Sophie and murmurs, "Should I? Or did you want to go?"

Looking relieved to have the pressure taken off of her, Sophie shakes her off and scoots back a few inches.

Kuniko turns back to you with a shrug. "Sure, I'll try that."

She looks thoughtfully at your dick, still holding it gently, and then takes it into her mouth again. This time, though, she slowly allows you more fully into her mouth, deeper and deeper in. It's no deep-throat, but she's got at least three-quarters of your cock in her mouth and it feels fucking incredible.

She nods to herself once she's as full as she can get it, a nod which tugs your cock in a pleasant way, and then she begins to slide you out.

"Wait," you say, "before you take me out, can I go in and out like this a little bit?"

She shrugs, and raise her eyebrows at you casually. Taking that as a yes, you slide yourself back into her mouth, as she presses her tongue obligingly against her cock. Then you slide out, and then back in again.

She starts understanding the rhythm, and begins moving with you as you slowly fuck her mouth. It feels incredible, and looking down at her gorgeous face, hair partially hanging down over her eyes, only makes it hotter.

The only thing that would be even better would be if you could see her bare breasts, or if you could actually fuck her pussy.

You're still slowly humping her mouth, and she seems to be enjoying the gentleness of it. But you want to ask for even more. She might say no, and that's fine....but as long as you're in this once-in-a-lifetime situation, why not ask?
