Evolving Francine and Fanging her

Francine's eyes reopen, as Stan stops thrusting. She sees Lois, her mouth latched to his neck, as blood runs down his chest. Francine wants to scream, but those eyes, those alluring crimson dots within blackness., and she just watches, and it turns her on more. She starts pivoting her hips on Stan's penis, as Stan's Skin gets paler. Lois removes her fangs from him, and licks the blood from her luscious lips.

"Mmm..now the fun begins....and soon, you'll transcend to humanity's next level in evolution like me " coes Lois.

Lois's arms still wrapped around Stan's body. Francine stares as her lips part "yes...please" she says.

Francine wants to feel her bite as well, just watching made her so wet and horny, she imagined it happening to herself. Stan's eyes goe pitch black, as he goes limp.

"He's transcending ..soon it will be you" hisses Lois, pulling Francine into a kiss.

Francine doesn't fight her, and kisses her back. Francine soon feels Stan start thrusting again. Back outside, Haley, now a vampiric whore herself, rides Quagula's shaft.

"Mmm..I never thougt..mmm..mm..id ever...feel ..mm..feel amazing " moans Haley.

"Giggaty....this is only...mm..the start my child" hisses Glenn.

As this is happening, a car crashes into the trash cans out front. Out from the drivers seat steps Peter, mostly drunk, followed by Cleveland, then Joe is strapped with rope to the back, he unties his wheel chair.

"Do you think the wives noticed we were gonee" stamers Cleveland.

"I doubt it..i..I bet they ..i" responds Peter before fallen **** on the lawn.

"Well..I should find Bonnie and make sure" replys Joe, heading back towards the house.

Down in the basement, Lois has Francine between her pake legs, eating out her vampiric cunt, as a reborn Stan plows her human cunt.

"Mmm..mm...thats it...get in deep..mmm..not bad for having a human tongue" whimpers Lois.

"Mistress....we can fix that...just have to turn her" replys Stan.

"Mmm..not yet...let her enjoy alittle, before her evolution " responds Lois, as Francine does what she can for her.

Lois then lifts her from between het legs. Francine mouth soaked with her vampiric sex fluids. Lois repositioned, and kisses her, tasting her own vampire juices. Upstairs Haley and Count Quagula has made their way back to the party.

"Master...whats our next move?" Haley asks.

"I think..we can start this party off with a good Fanging orgy, but first let's lure a couple more to the side, and evolve them first." Responds Glenn.

Back down stairs, Stan has start plugging Francine's ass with his penis, as Lois now tends to her human pussy. Francine moans as Stan pivots, thrusting her ass, and Lois rubs a claw finger along her soaked slit. Lois spreads Francine's pussy lips, and extends her vampiric tongue deep into her folds her tongue licks at the inner walls of her vagina, as she gives a wink to Stan. Lois's mouth then moves closer into her crotch.

"Mmm...oh yes...mm...Aaaaaahhmmm" moans Francine, as she feels Lois bite into her crotch area.

Stan sees this, and tilts her head to the side, and baring his own fangs. Sinking them into his wife's flesh. Francine then feels a pleasure she has yet to feel, as the two feed upon her. After a few seconds, Francine's skin pales, as her breasts become perkier as Lois's did. Her canines extend into fangs of her own, as her eyes close, and she goes limp. Her fingernails extend into claw like tips. Francine's eyes then reopen as pitch black voids. Francine's blonde hair becomes more luxurious looking as well.

"How do you feel?" Hisses Lois.

Francine's pitch black eyes closes, and replopens with crimson irises, glowing brightly.

"Amazing mistress...thank you for evoking me to humanity's next step" she coes.

Lois then heads back upstairs, but this time, she's tired of hiding her true self, and her body. She leaves her clothes laying in the basement, and makes her way to the party. Stan and Francine though, goes back to fucking each other , seeing what exactly their new forms can handle.
