Lily, her older sister Amanda, her younger brother Johnny, and her parents were what you might call ‘progressive’ – in the fullest perversion of the term.
On politics alone, her parents believed in the legalization of all drugs, and were avid consumers of weed since high school. They openly smoked it around their kids, and sometimes with them.
Believing privacy a barrier to humanity, their small house was devoid of doors, not even to the bathroom, and not even a shower curtain. None of them really cared however, they were all religiously nudists – it was basically manners to them.
Lily’s parents weren’t sticklers on gender pronouns however; it seemed to be too much work. In fact, despite being progressive in these hippy ways, Mother and Father enjoyed some aspects of traditional gender roles, but with more equality for women. They felt it brought them closer to how natural people lived, and it made for great dirty talk during sex.
If Lily’s parents believed drugs should be legalized they wanted sex to be legally required for them, and they acted like it. It seemed like nothing could keep Father and Mother from each other. They were always ready to go, watching tv while nude and just doing it on the spot, as long as the kids weren’t around.
Now despite the lack of doors, they did have curtains on all windows, and dark ones at that, plus a mean door lock. This was for a very important reason.
Mother and Father would be send to prison for what they do with Lily, Amanda, and what they will probably do when Johnny is deemed old enough.
It started just with a decision. A reconciliation of logic. Mother was an opinionated woman. She liked to be right, and Mother believed that desires are to be explored, not crushed.
When Mother experianced sexual urges about her eldest daughter Amanda when she was only 16, a deep conflict consumed her for a day. But the principles she had created her life upon won out.
Thus, one late night while watching TV, Mother was sitting on the couch with Father, Amanda across the room in a recliner. They were all nude as per usual. Father wasn’t in a horny mood, and had never thought of Amanda in a sexual way.
Mother however became hot and bothered. Her pussy pressed into Father, he felt it become wet. Mother continued teasing him. She got up to grab the TV remote, bending over sexily at him. Amanda seemed to notice, glimpsing at Mothers massive natural breasts.
Back on the soft couch with her husband, she made herself easy and ready to fuck. Father could tell, but said nothing.
Mother grew frustrated, and took more direct measures. Both Mother and Father lied on their side, and Mother scooted her thick, round, fuckable ass down to his cock. She grinded in place, his cock between her ass cheeks, stimulating him in no subtle way.
Amanda felt she could only watch; transfixed by her Mother and Father.
Not much teasing is required to signal and ignite passion in Father; his urges took over, he stopped caring. He grabbed a hold of his cock and his wife, and a loud moan echoed through the house, probably waking little Lily. Amanda only stared, grew red faced, and became wet.
Slow humping began, Fathers well-trained muscles easily fucking her hard. He had been fucking her twice a day for years, and he was a pro. But now he felt nervous, he didn’t dare look at Amanda.
Mother however smiled at her as she whimpered, as she kissed, as she took his massive rod. Amanda only stared back, in disbelief. Sure, she’d seen them fucking. They had always gone to the bedroom however. *They’ve never fucked so… invitingly,* Amanda thought.
Just as mother had made the decision to fuck boldly in front of Amanda – following a brief day of doubt; Amanda too had a doubt. But while it took Mother a day to decide to follow her desires no matter how perverted, it only took Amanda one second.
Amanda spread her legs and dug her fingers in her wet cunt, staring at her daddy’s cock fucking her mommy’s holes. She was 16 but Father was still Daddy. While Daddy had never dreamed of Amanda, Amanda had explored her sexuality with Daddy as the center piece in her mind. She saw his cock flaccid every day, but masturbated to it every night, crying out to him in her mind for his big cock in all her holes. She wanted to make her Daddy so happy.
Now that he was fucking, Father began to steal looks at Amandas wet pussy and her fingers. He began to buck harder, dreaming of his daughters slutty wet pussy, he realized his wife had gamed him into this, but he cared very, very little now.
No, Father did not fuck Amanda that night. But it opened the door unknowingly. Mother did not tell him, but she knew where his cock would end up. That same night, in front of Amanda, Father let loose inside Mother – the both of them came at once, their daughter’s mouth agape, and Daddy’s cock spurting a hot load of jizz into Mommy, impregnating her as she stared at her daughter, and managed to wink.
9 months later, Johnny was born.
