She is yours to take

You kiss Gwen, allowing your hands to massage her ass. You bring a hand up to her back and deftly pop off the clasp of her strapless bra.

She pulls back, a slightly shocked expression. "Right here? With Tina watching?"

Tina locks her eyes with Gwen's. "I would love to watch. There is no need to be bothered by it."

Gwen kisses you back fiercely. She locks eyes with you. "Take me. Take me now!" You can feel her arousal, all concerns of being watched gone.

You unzip her dress. She allows her dress and bra to fall away. After slipping off her panties she stands before you gloriously naked. She unbuttons your jeans, nearly ripping them in her haste.

Dark lusts swirl within you. You want Gwen. You want to have her, to taste her. You can hear the rapid thump of her heart beating.

You push her back to the coffin and bend her over. She moans as you caress her inner thighs, spreading her legs wide open.

You slam into her soaked pussy. She gasps in pleasure. You pick up your rhythm and glance in Tina's direction.

She is sitting on the floor, her own dress tossed aside. Her breasts are bare, two perfect half cantaloupes. A pair of erect nearly black nipples cap the round mounds of breast flesh. She slides of pair of black clawed fingers into her pussy. They come out wet with her juices. She looks you in the eyes and licks her fingers.

Gwen's moans refocus your attention on her. You feel an orgasm build. You feel your eye teeth lengthen into fangs. You see the vein you wish to take. You come.

You drive your mouth into her neck, your fangs penetrating her with tiny pops. Blood begins to come to you. It is luscious.

Gwen yells. "Fuck yes! Take me, take all of me!"

Suddenly Tina is next to you whispering in your ear. "Drain it all, Jack. Take her. Make her one of us."

The realization hits you. If you keep drinking her human life will end. You aren't sure you want that for Gwen. You pause.
