Try to rationalize it (And fail.)

After thinking for a while: "...Yeah! Yeah! Sex isn't a sin and what i did wasn't bad! It wasn't me who was in the wrong, it was my dad– Whoops!" You dropped your soap. You bent over to get it, and you immediately felt your virgin asshole bulge out at the thought of your father's hung dick perching near your butthole.

You jumped up and screamed, "I'm not gay!" While cupping your tight buns.

You paused. Then sighed, rubbing your temples. You began chant-whispering: "It-was-fun, it-was-fun, it-was-fun. It-was-good, it-was-good, it-was-holy..."

It was no use: your Dad was amazing, smelled good, and had a big penis. There was nothing morally good or right about being turned on like that, so why did you suck him? Were you thinking, or were you not...a good person at heart?

"Mom..." You closed your eyes, picturing your mother as a naked babe. You imagined yourself smelling her freshly shaven vagina, and lapping at the smooth skin around the twat. You also imagine her boobs, her hair, and her face; and you gag. It was your mother and you felt physically sick picturing intercourse with her. It was morally wrong and disgusting, so why...

You start to imagine Dad again and your body immediately increased temperature. The cold water droplets threw themselves at your growing cock, and you were surprised when you were rock-hard already, pointing up towards God.

"How?" You murmured, "I didn't even think of my Dad's big body yet!..."

Perhaps it was the taboo surrounding your father that was arousing you, not your Dad's actual body. But if that's true...that still doesn't explain why his cum tasted so yummy, or why you received **** enjoyment when you unzipped his pants for the first time. Why can't you rationalize that?

"I need a fucking girlfriend. Fuck you Dad, you fucking homo." You angrily growled; you know you don't really mean it though.

After the shower, he browsed his phone for information about human sexuality, but he was getting distracted by a revolting stench; Dad's cock musk still lingered in your bedroom, so you mindlessly looked at some porn because you were really bothered: blowjob porn, all guys, with one younger cutie and another older hottie.

Mom was watching TV in the living room and was propped against an arm of a couch, her legs stretching out to the other couch cushions. She was watching an old TV sitcom that she kinda liked; it was about aliens masquerading as people to become friends of humanity. Mom looked up when someone came from upstairs to join her.

"Hey baby," Dad huffed out, giving his wife a sweaty, but relaxed, grin.

Mom smiled; she shifted her legs and patted the seat next to her. "Can't sleep?"

"Hah, you're absolutely right!" He plopped next to her and brought his arm over the top rim of the couch. "I've had a weird day, but I'm not going to question it."

Mom hugged Dad's chest and took a whiff. "...Huhm. You smell really good–" She abruptly stopped talking and sat up to give Dad a weird look. "Did you masturbate? I smell semen off you."

"Hah!... Hun, yes I did. And I had a great session tonight. What are we watching by the way?"

Mom palmed Dad's outstretched hamstring. "It must have been one masturbation session. When did you blow?"

"Oh, Oh! This show?" Dad shook his head disapprovingly.

Mom removed her hand from his thigh, "Hey, I think I like it. What's your deal, you sweaty man?"

Dad paused. "I don't know. Good question. Good question, Hun." He smirked at her. "You know, I'm really proud of my family."

"You better be!... Oh... Have you talked to John?"

"...I'm his father. I think I'll work some things out with him." He rubbed his stubbly chin. "I hope he'll be okay with that boyfriend of his."

"Hm, young love." Mom turned back to the TV.

"...Y'know, I actually like this show–"

"I know you do, you dirty cock sucker." Mom landed on Dad's lap and fingered his legs while watching intently at the TV.
