Is once enough?

Vanessa looks at me with a concerned look. "I want to …. I want you …but."

I raise my hand to stop her. "Rest easy my child. Nothing will come to you that you do not fully and completely desire."

She moves toward me and caresses my firm chest. "Once … " she whispers as she bends to lick at my nipple. The wet touch of her tongue to my flesh causes a surge of blood to my loins. I am harder than I've been in ages. "Once .." she continues "… won't change me, will it?"

"Not … Not physically." I stammer as Vanessa hand finds my cock and begins to stroke it. She looks at me with a playful smile. "But your libido will …"

Vanessa interrupts. "Oh, I'm so hot already," She positions herself over my member, straddling my furry hips. "I've just got to have you …" Vanessa runs her wet lips over my cock head, teasing me. But I will not take her unless she asks. "I've got to have you inside of me!" she moans. Or until she takes it herself.

And Vanessa does just that, easing the head of my cock into her wet pussy, Vanessa lets out a squeal of delight. "Ohhhhhh, fuck! That'ssss Sooooo Fucking Gooood.!" Then she carefully lowers herself until my full length is within her.

We ease into a rocking motion, my hips moving in counter-balance to hers. She wraps her arms around me, pulling my mouth to hers. We kiss deeply as I move within her. Her moans rumble down my throat. Her slick pussy rises and falls over my shaft. Her pert breasts sit before me and knead them with my hands and draw her close so I can suck at one nipple, then the other. Vanessa's eyes close at the attention I am paying to her succulent body. I fell her movements quicken on my shaft. Her eyes flutter in delight.

"OH, PAN!" she screams. "I'm gonna CUM!"

She thrusts herself hard on my rod.

"Cum inside me!" she begs. "I want to feel your hot cum in my pussy. Feel it inside me. Fell it drip down my legs! Give it to me! Give me your sweet CUM!"

Vanessa can speak no more as she moans and grunts while thrashing down on my member.

Her pussy throbs and contracts as her orgasm begins, milking my seed from my cock. I feel it build within my balls. My cock burning with the impending release. "I'm going to cum." I warn my lovely partner.

Vanessa smiles at my words. "Yes, Yes! Cum with me! Cum in me!"

"It will begin the change … and there's no turning back," I admonish my lover.

"Oh fuck, yes!" Vanessa screams. "Fuck me. Cum in me! CHANGE ME! I'm yours, Pan. I'm all yours to fuck! Change me and fuck me forever!"

Such an invitation I could hardly ignore, and I thrust deeply into Vanessa. Her mouth opens wide, but her pleasure is so great she's unable to speak. My seed spurts forth, filling Vanessa's sweet pussy.

My lover collapses, exhausted and barely able to move. Her chest heaves against mine. After several minutes, she smiles up at me as she runs her long fingers through my hairy chest.

"WOW!" she says with a grin. "That was …that was just." Then she shudders, unable to put her joy into words.

Vanessa extricates herself from me and settles into my loving embrace, one of her legs draped across mine and her head nestled into my shoulder. Sleep is about to overcome her.

In her last moments of consciousness, she looks to me with a quizzical expression.

"I don't feel any different," she says, a touch of disappointment in her tone.

I pull her close and rub the small of her back. "In time you will, my love. When my seed takes hold, you will have the insatiable sex drive of a satyress."

"Then what?" she asks.

"That choice, my dear, is up to you."

I watch as Vanessa falls into a blissful slumber.

I know that by morning her libido will have accelerated ten fold. I know that if I am there, her judgment will be so clouded by her need for sex that she will take me without concern for the consequences.

And I know that Zeus would not appreciate such behavior. So I pen my love a note, promising to return the next evening. I wish her well with her new lusts and assure her that the next step on her journey is hers.
