Gently encourage him to give you another round

As your Daddys member starts to stir to life, you press your butt against his crotch. Wiggling, lifting your leg a little bit, you manage to slip the cock in between your legs. The slick, sticky mess between your legs working as a lubricant, you start to stimulate it with your thighs. The head rubs against your out lips, sending shivers of anticipation through your body.

"You want another round already, Julie?" he asks. "Well, I wouldn't be a good Daddy if I didn't give you what you wanted, would I?"

"No-o," you answer him, all cutely and innocently.

He stops playing with your breast as he pushes your upper body away. The change of angle allows him to slip back into you. This time, it's not as painful, though his member still feels huge inside you. "You're cock is so big, Daddy! Oh, I love having your big cock inside me!"

"I love having my cock inside you, Julie," he replies. "You're so tight. So firm. And not only your pussy." He caresses your butt, slides his hand up your waist and reaches for one of your youthful breasts. "And you're such a good girl, aren't you?"

"Am I, Daddy?" you ask him, as you continue to press against his slow, heavenly thrusts into you.

"Yes, girl, you're the best girl I could ever dream of. Beautiful. Obedient. Not to mention horny. You'd make a perfect wife." Again, he mentions making you his wife. Is he planning on making this permanent? Lying there, with his cock inside you, feeling these strange feelings, the idea does not seem alien.

"Your wife? But I... I can't. What... what about David?"

"What about him? I'm sure he'd manage, even if he got a step-mother that was only a few years older than him. Besides, he's off to college soon."

Weird. He was talking about you - the real you, guy-you - as if he was a different person. And in a way, it made sense to you. You weren't David, his son. Not here and now. David was someone else. You were Julie, his date. His girlfriend. His little submissive slut.

"Oh, then I can have you all for myself!" you start to play along. "I could move in with you. Keep your house. Serve my big strong man. And we could make him some little brothers and sisters." You're not sure where all of this is coming from, but it's getting you extremely aroused. The idea of being a kept woman. Of being impregnated by your man. "Oh, Daddy, please cum deep inside me!" you scream, as an orgasm starts to wash over you.

Your talk pushes him over the edge as well, and you come together, your convulsions milking his cock of its seed, carrying it deep inside you.

As you both come down from your high, his tone changes. "Listen, Julie, I need you to help me out a bit now. As you've probably guessed, I've made a deal with Melissa, Mr. Gordons Mistress from downstairs. She wants to come up here with him, and have you tease him a bit. Humiliate him a bit. Maybe let him eat you out. All while I'm having sex with Melissa. If we do this, I'm certain to be fast-tracked for promotion. But I don't want to pressure you into doing this."
