Join with her willingly (Consensual)

“No...”

“I want this...”

I look down from my wife’s face and stare at her beauty as I circle her thick nipple with my thumb. I look up into her eyes as I squeeze her full C cup breast resting in my hand.

"Do it." I whisper.

She smiles, pleased, and her eyes flare a deep red. Her lips seem to swell, and turn more reddish, and I watch as they tremble and curl back as her long ivory fangs extend.

I feel her clawed hand wrap firmly around my penis as I watch the fangs in her mouth, with a scared arousal.

She tugs on me, and I gasp in pleasure.

"You give yourself to me, freely?" she asks, the long fangs in her mouth slurring her speech slightly.

"Once I bite you, you will be mine." she says, her eye brows raising, inquisitively... seductively...

She continues tugging on my penis, slowly accelerating the pace. My eyes roll back from the pleasure. "Yes...." I gasp. "oh god yes." I thrust into her hand trying to find a rythm that matches hers.

My eyes glance to the punctures on her neck as she continues beating me off. "Mark me with your bite... like she did to you... make me yours."

She snarls as her mouth opens wide, saliva coating her lips and fangs. I feel her free hand grab my neck and I close my eyes as her clawed thumb tilts my head to the side.

Her sweet lips kiss my neck, and

"Ah! ah! Ahh!"

Her fangs push in.

The sharp pinch only lasts a second, before her fangs tear my skin.

"ahhhhhhh...." I gasp, as I feel my face flush red with pain. A sense of submission floods over me, and I go limp in her arms.
