Note: Thank you for the criticism. Foremost, this is the story of how several family members come together, and my choice of chapter divisions is an attempt to make the story (which of which I have not yet posted one tenth) more manageable. I do not mean to be frustrating my readers. Your comments are appreciated.

Vincent had been in his room, doing some homework when he decided he needed to go to the bathroom.
It was a quick trip, just down the hall and to the left. Opening the door, he realized that Jonah had the TV running loud. Didn't he have any consideration? But Vincent had work to do, and he was thinking about maybe having a couple dates this weekend, so he wanted to get his work finished.
Coming out of the bathroom, there was a lull in the sound for a moment. That's when Vincent heard grunting. Male grunting, coming from his sister's room.
The whole thing seemed improbable. His sister had been famous in high school for being "cold", and surely she didn't have the nerve to bring a man home when their parents should be there any time?
The television had resumed its loud ascent into madness, and Vincent decided that if Stephanie did have the nerve for that, he would find out who had the nerve to come in and fuck her. He crept as quietly as possible toward the door, and put his ear closer to the door jamb. He listened.
Rob was stroking the head of his daughter, and staring at his wife as she took her shirt off, and discarded the bra. Her large breasts settled on her chest, still firm but needing a little more support now. She rarely would remove her bra for sex anymore. She insisted on "preserving the goods". But her breasts were bare and heaving as she watched her daughter prepare to remove her own father's underwear. The naughtiness of the scene was delicious to her.
While Jillian was watching, Stephanie braced herself to cross what she thought of as the line.
She was about to see her father's dick, and already from the shape of it inside the cotton briefs she knew that it was thick. Very thick. Would she be able to fit her mouth over that? The one boy she had let inside her mouth was so much slimmer. In fact, that boy wasn't very large at all. But her father's prick was so hard, and when she caressed it through the material she knew that seeing it would mean she had to have it. And perhaps not just in her mouth.
"Sweetie, please. Suck Daddy's cock for him. No more teasing."
Stephanie smiled at him. "Daddy," she said with her hands on the waistband of his briefs, "I will." She slowly tugged the waistband down over her father's pelvis, and watched as every delicious inch of his penis came into view. When the cloth was down his thighs, she simply dropped it and let her father step out.
Rob's cock was about five inches long, but very thick. After staring for a moment, Stephanie reached out and grasped her father's cock at the base. Her middle finger was the only one she could touch to her thumb. She smiled, this time at the cock.
"Steph, honey, please. At this age being teased is simply unbearable."
Stephanie giggled. Her father was only 45. But yes, it did seem to her a bit unfair. She took her left hand, and began to massage his balls for him. He groaned.
"Mm Daddy does that feel good?" she asked, rubbing her face against his cock softly.
"Ooh baby you're so sweet to me. Please, lick Daddy's cock."
Stephanie complied, taking her wet tongue from the base of his cock's underside and trailing it up to the head. She then licked the engorged head, swirling around it with her tongue while Rob sighed.
"Baby, after you get me nice and coated in your saliva, I want to go in your mouth." He stroked her hair again, and then gathered it on either side of her face. He didn't want to miss a thing.
... "Oh God Steph your mouth is so hot. Don't worry about getting me all the way in. Oo yes Baby, just keep stroking me like that while you do it. Mmm.."
Vincent's eyes were wide. How was this even possible? It was... It was wrong. His father was two-timing his mother with his sister? It was absurd, but it was true and O it was hot, as his own erection testified. Vincent felt guilty but the thought of his notoriously stiff sister taking her own father's hard on was just so naughty... What a slut!
Vincent wondered if he could get Stephanie to take his own dick into her mouth. His father's infidelity seemed to him the perfect leverage. After all, it was only fair that if his father could have some sort of illicit relationship with Stephanie, he'd let Vincent have his own share.
What was her body like? he wondered as he reached for the door knob. The girl was so careful, taking clothes in with her to the shower and never swimming without an extra-large T shirt to cover.
What would she feel like, with her lips wrapped around his cock?
... When I heard the door knob turn I tried to pull back, but Daddy had me by the back of the head and wasn't going to let go, even if we were getting caught. My protest ended in a gurgling sound against his cock in my mouth, as he held me there.
