Sister is based on Dani Woodward, Mother is based on Lezley Zen.
"Kids, we're home! How was your Halloween?" I heard my mother, Lezley, call out as my dick was inside my sister Dani's pussy, in the master bathroom shower.
Thinking quickly, I jumped out of the shower and collected my clothes. To get to my room would mean crossing the stair banister, overlooking the front door. I had to make it look like only Dani was in the shower. I had no other choice, I opened the window and jumped out. One story up is no big deal; a diving tower at the summer lake is higher than that. I landed in the mulch and quickly put my underwear and pants on, then crept around the back of the house to the front. I climbed onto a garbage can and reached the ledge of my window. I had it slightly ajar and managed to open it and wiggle in. I hoped no one saw me.
Mission accomplished. Dani using mom's shower was nothing out of the ordinary, and if mom saw her slutty costume, that was her problem. Meanwhile, I had felt a woman's warmth. My sister's warmth, but a hole is a hole. I dried myself off with some socks and put on fresh clothes, then cracked open a notebook to make it look like I was studying in bed. Mom came to check on me.
Maybe it was the fact I had just fucked my sister, but suddenly I realized mom was fucking hot, too. Jet black hair, huge fake boobs dad bought as a present for her (for her...), long legs and a thin body with a wide ass. Dani got her body and similar face, with dad's red hair. I had her hair with my dad's body and face. Funny how that happens. Mom was dressed in her Cleopatra toga; no need for the Liz Taylor wig since she already had that hair.
"How was your Halloween, sweetie?"
"Oh it was quiet. I just stayed home."
"Too bad. Maybe next year in college your sister can take you to a party. They get pretty wild."
"I can only imagine." Mom turned and walked away, leaving my door open. I could see her bikini tanlines through the flimsy fabric; she wasn't wearing anything under the toga. Dani's quote ran through my head:
"Oh please. How do you think we were born?" Were all the women in my family nymphos?
We spent the rest of the weekend recovering. On Monday, I came home from school to find Dani home early. She had a light schedule on Mondays and skipped it. She was on the couch in the family room watching some stupid reality show. I sat down next to her.
"Hey, little bro."
"Hey... so are we going to talk about... us?"
"What about us?"
"Uh... the fact we're brother and sister and we had sex."
"Did you enjoy it?"
"Of course I did." She was wearing a teeny tiny lavender skirt and matching tank top. She lowered the top and raised the skirt, then started playing with her pussy.
"Did you like being inside your sister?"
"Uh huh..."
"Did you like fucking her pussy?"
"Uh huh..."
"Did you like cumming inside her?"
"Uh huh..."
"Do you want to do it again?"
"Uuhhhhhh huh."
"Then do it. Fuck me." I stood up, took my pants off, guided my cock, and fucked my sister again. She was already soaked and my dick practically swam inside her hot hot pussy.
"Oh fuck yeah! Fuck your sister you little pervert! Use my body for sex! Fuck me! Fuck me harder! FUCK YOUR SISTER HARDER!" I started pounding her so hard we were moving the couch with every thrust and knocking things off the end tables. It was amazing the effect my sister's vagina had on me.
"From now on whenever you want to cum, you use my body! Use me like a dirty whore!!"
"Yeah you're my dirty fucking whore aren't you!"
"You know I am, baby! Cum inside me! Give me that hot fucking load of forbidden jizz!" I did so. I inseminated my sister again. Afterwards we straightened out the room as best we could.
For the next few weeks, Dani and I continued fucking each other in secret. I would drive to her sorority house after school, pose as her boyfriend, and fuck her brains out. On weekends she would come home to do laundry and get free food, we would wait for mom and dad to go to bed and fuck in my room. It was an all you can fuck sister buffet.
We bought one of those sex position check off posters and went through all of them. Wheelbarrow, lotus, piledriver, sidesaddle, teabag, crazy monkey. We did the whole kama sutra. My favorite was when our parents were watching TV, and Dani invited me into the kitchen. She hiked up her skirt, revealing no panties, sat on the counter, and had me fuck her right there, just a few feet away from getting caught. When I whispered I was cumming, she got on her knees and sucked me dry before swallowing. We then went back to watching the movie on the couch with mom and dad, my swimmers still in Dani's belly.
Winter break came for both of us. Dani somehow was getting good grades at her college despite partying all the time. Don't know how, I just know she wouldn't suck my cock after her finals because she said her jaw hurt. Maybe she chewed on her pencil too hard or something.
By chance, I saw an advertisement by flier for a swingers party on New Years Eve. It would have gloryholes, orgies, even a dungeon. Masks were encouraged. One problem though, we had to show our IDs to get in, and Dani and I had the same last name.
At home, Dani was in her room reading something on her laptop, wearing pink yoga pants and a black sports bra. I showed the flier to her to get her take on it.
"Sounds fun, Mikey."
"How will we get past the ID check? They'll know we're related."
"They'll know we have the same last name, not that we're siblings. We'll go as husband and wife."
"Won't we need wedding rings?"
"Don't worry about that. Doesn't strike me as a place many people care about their vows."
The night of the orgy came, New Year's Eve. Dani and I headed out in our winter gear for the perilous journey from the front door to my car; Dani in her famous giant pink puffy coat with Princess written on the back, and myself in a t-shirt and jeans because I was not a woman. Outside, it was cold, snowy, icey, and braving all those elements would make Dani's pussy all the warmer by comparison. We told our parents we were going to a friend's house, one of Dani's slut friends that would cover for us if needed. I drove us to the address, it was an old mill converted into businesses. After parking we walked up a giant spiral stairway in a turret looking spire to the third floor where a guy let us in. Inside were more hallways and a desk with a lady wearing sheer lingerie. We walked up and greeted her.
"Members?"
"No, we're new." I answered.
"No problem. IDs and 20 dollars registration, please." Moment of truth. We handed her the IDs. She scrutinized them for a few moments. Dani then grabbed my arm and brought me in close.
"We're newliweds!"
