Before Dan had a chance to respond to Summer's question, Summer took matters in her own hands as she held his penis in one hand and swirled her tongue around the head of his penis. The electric spark shot through his body almost made him cum on the spot. Summer pulled her mouth away. She didn't want this to end already.

Summer's eyes started to glow as she looked into her Dad's glazed over eyes.

"Daddy, I just wanted to show my appreciation for being such a good parent for all of these years. I bet Mom hasn't done this in a while...." Summer starts to lick the shaft of his cock as Dan moans. All guilt and remorse are gone from him. But one thought popped into his head through the haze, his wife was upstairs and could be down at any moment. Summer sensed the slight panic and whispered at her Dad.

"Don't worry about Mom. I have the feeling the Emma is with her right now and they are having some special Mom-Daughter bonding time."

Summer went down on the twitching cock and swallowed the entire shaft. Dan groaned as her mouth was massaging his cock and was enjoying the best blow job of his life. Summer pulled off him again when she sensed that her Dad was about to cum.

"Daddy, are you enjoying this?" Dan moans in response. "I can make this happen whenever you want. You can fuck me.....and Emma too. I bet Emma would love to fuck you too." Dan groaned, almost in frustration. He was so close to getting off. Summer was slowly jerking him off. Fast enough for it to feel good but not fast enough to make him cum. "What do you say Daddy? Want to fuck your daughters.....forever? All of them?" Dan forgot about his youngest, Kate. Darling ... innocent..... Kate.

The pheromones in the room have obliterated the moral fiber of his being and Dan embraced all of the impure thoughts rushing into his head right now.

"God, fuck yes."

Summer laughs. "Not God. Something better." Summer leans her head back and hisses as her inch long fangs extend. "I knew you had an evil pervert inside of you. Wanting to fuck all of your daughters. So wrong. I love it."

Without any further hesitation Summer sunk her fangs in her father's throat while jerking him off. The moment her fangs entered Dan orgasmed and cum exploded out of his cock for the last time as a human.

Summer had her Dad's cum all over her body, his blood all over her mouth. She grinned when she heard a female moaning upstairs. She couldn't tell if it was her Mom, Emma or maybe even Kate.

She bit into her wrist and pressed the wound to her Dad's lips.
