"What is wrong with you, Nikki?"
"What are you doing home, bitch?" grumbled Nikki. She quickly removed her hand from her crotch and fumbled for the remote control. Her sister, Edison, glanced at the big screen TV, which currently displayed a naked woman getting her face peed on by three men.
She snickered. "Why do you watch such sick movies?"
"Why do you watch your fucking Harry Pothead movies?"
"It's not Harry Pothead. It's Harry Potter. And you shut up about him."
"Oh, did I hurt your feelings? He's not real, psycho. He doesn't exist. You do understand what fiction is, don't you?"
My daughters, Nikki and Edison, are complete opposites. Edison is a nerd's nerd who has read every Harry Potter and Lord of the Rings book at least four times. And Nikki has never read a book in her life. Nikki is a very smart girl, but she has ADHD and could never sit long enough to finish ten minutes of homework.
She just turned nineteen and is eleven months older than Edison, who started college last week. They haven't seen their absentee mother in sixteen years, so I have raised them on my own. And I've been more of a referee than a father.
"Aren't you supposed to be at work?" sneered Edison. "What happened, you get fired for masturbating on the job?"
"Eat my pussy, bitch." Nikki went into the kitchen, opened up the liquor cabinet, and made herself a vodka and lemonade. "It's my day off, so fuck off."
"Dad told you to stay out of the liquor cabinet."
"I'll make you a deal. You shut up about Harry Fuckhead and I'll quit drinking."
These two fight more than they breathe. I am so exhausted with their constant bickering that I hate to come home. Nikki, my freckled and fiery redhead, has had dozens of boyfriends, while Edison, my blonde and blue-eyed cerebral nerd, has never been on a date. And she lives to get dirt on Nikki.
"You tried to seduce dad last night, didn't you?"
"What the fuck are you talking about?"
"You were in the jacuzzi with him."
"Why, did you flick your twat while watching us?"
"You were having sex, weren't you?"
"All we did was smoke some weed."
"You were sitting right next to him. Nude."
"I always jacuzzi nude."
"Bullshit. You're hitting on dad."
"Ah, poor baby. You sound so jealous. Too bad you're so fucking ugly. I guarantee you that dad's dick shrivels up whenever he sees you. It's so sad that it's never getting up your ass."
"You're so disgusting."
"Go suck Hobbit cocks, you fucking nerd."
Nikki had the last laugh, and it echoed through the house as Edison went into her bedroom and slammed the door.
* * * *
I got home from work and quietly went upstairs to my room, hoping that my two daughters didn't have their usual standoff today. But no such luck. I could tell that they had a bad one from Edison's hard knock on my bedroom door. I wasn't even home for two minutes.
Edison's androgenous face was set on top of a long neck and a tall and thin body, with narrow hips, a tight ass, and a flat chest.
"Daddy, do you have a minute?"
"What's up?"
"What happened last night?"
"What do you mean?"
"In the jacuzzi. You and Nikki were nude."
"Edison, everyone gets in the jacuzzi nude. Even you. What is the problem?"
"I don't get in with you. And you were smoking marijuana."
"It was just half a joint, Edison. Not even enough for a good buzz. Please, I don't want to deal with this now, I'm tired."
"She was masturbating again, daddy. This time in the family room."
"Nude, or did she have clothes on?"
"Why does that matter?"
"Edison, do me a favor. Don't look at your sister anymore. Don't talk to her. Don't even think about her. Just pretend you're an only child."
"You always take her side, daddy."
"You're in college now, Edison, you shouldn't be acting like you're nine years old."
"She got into the vodka again."
"I didn't buy any vodka. She must have gotten it from one of her boyfriends."
"So that means it's okay?"
"Edison, I can't police Nikki all day and night. And you shouldn't either."
"I can't believe this. You let her get away with murder."
"Don't you have school tonight?"
* * * *
As soon as Edison left for school, Nikki rushed into my bedroom.
"Hey, daddy, the warden's gone. You wanna do some amyl with me?"
"Nikki, quit doing that shit, you're going to get sores on your face."
"You should try it, daddy. It makes you cum hard. Come on, I've been wanting to fuck you all afternoon."
Nikki got right down on her knees and pulled down my gym shorts. She opened up her small bottle of amyl and sniffed in both nostrils. Then put my cock in her mouth. And she really has a thing for sucking on my balls. She popped them in her mouth and swallowed them deep.
"Careful with your teeth, baby."
She put her mouth back over my cockhead and gave me a hot and sloppy blow job. And she has very active hands, stroking me and playing with my ass as she sucked my cockhead deep into the small of her throat. Her finger found its way up my ass, and she milked my prostate until I unloaded several thick spurts onto her tongue.
As always, it was a great orgasm, and she didn't miss a drop. She moans when she swallows, and does it quickly, as she always takes advantage of my erection before I get soft.
"Get on the bed, daddy."
She climbed on top of me, guided my shaft into her steaming hot young cunt, and sniffed the bottle of amyl. In both nostrils. She slammed down hard on my shaft, and I got in deep.
"Daddy!" she screamed as her amyl-assisted orgasm really blasted her off. "I love you!"
She fell down on me, pushing her tongue into my mouth as her vaginal spasms continued for another minute. And after Nikki makes me cum, she always uses the leverage to plot against her sister.
"Daddy, you got to get rid of her."
"What happened this time?"
"She walked in on me again."
"Were you rubbing your pussy in the family room?"
"I don't like watching porn in my room, the TV is too fucking small. And I wasn't nude, I was wearing leggings."
"Unless you're in your bedroom, keep your hands off your pussy, okay?"
"How is this my fault?"
"Nikki, I'm so sick of all the fighting. And don't get in the jacuzzi with me anymore. She's spying on us."
"What's she gonna do, call the cops?"
"She'll drive me crazy. You know how she complains about everything. So please, be the adult in the house, and don't give her anything to complain about."
"She'll invent something, daddy. It would be heaven around here if it was just you and me. We could fuck anytime we want."
