Surprise!

Jen stops sucking Rob's dick and looks up at Emily's voice. There's no remorse in her lust filled eyes, just anticipating of more dick. Rob looks over at his wife and smiles, showing his fangs.

"It's your turn next, my dear wife."

Emily smirks and hisses as she shows her growing fangs. "Oh I think you're a little too late for that. I was hoping to have Jen all for myself. Mind if we share?"

Rob, surprised, motions Emily over. She sits on the couch, lifting her dress, showing her pantyless pussy with two bite marks are on her pussy and thigh. Rob re positions Jen so her head is down in front of her sister's pussy. The throbbing lust in her body dispels any moment of hesitation in the incestous act and she dives into the pussy, licking and sucking the cum out of whoever just fucked her. Rob's engorged dick barely fits into Jen's wet pussy from behind and he hears her moan as he thrusts into her

After a few moments Rob cums into Jen, filing her up and pulls out of her. Emily grabs her sister's head as Jen is sucking on her clit, getting her close to orgasm. Emily's eyes glow red as she cums. After a moment Emily lifts Jen's up close to hers and starts kissing her, tasting her own juices on her sister's lips. As Emily starts to kiss and lick Jen's neck, Jen moans..."Do it.....make me.....vampire."

Emily smiles and whispers "My pleasure, sister." Jen's body is rocked by pleasure as she feels Emily's fangs enter her neck and her sister drinks her blood. She pauses after a few moments and hands Jen over to her husband to have the rest. Jen moans again softer as Rob's fangs enter her.

Emily lays her bloodied head back on the couch as she watches her husband makes a cut in his throat and has her sister start to drink from him.

"What a wild fucked up night this has been." Emily thinks as she runs her tongue over her fangs.
