"How you feeling, Kiddo?" Dad was asking because I had had a bit of a cold earlier in the week. He was always so considerate before stripping me naked and then dominating, humiliating and ruthlessly fucking me. Of course, along with the help of my beautiful mom.
"Great. And I'm excited." Tonight was going to be special because it was the first time it wouldn't just be the three of us. Mom and Dad had decided that it was time to share their recently submissive teen sex toy of daughter. I was a bit nervous, but the thought of someone else joining in the games of dominating me, and maybe fucking me, had me buzzing.
Dad matter-of-factly slid his hand up the hem of my light sundress and rubbed two fingers up and down my panty-clad slit. He chuckled, "Yep, already wet."
I pushed my groin into his hand and reached for the bulge in his pants. With his free hand he suddenly slapped my face. "Did I say you could touch me, slave?" This was his domineering voice, so different from his usual loving father voice, the only voice I had heard from him for the first eighteen years of my life.
I looked down at my bare feet. The burning of my cheek made me even wetter. He could tell. He chuckled and brought his damp fingers to his nose, breathed in my scent, "Such a horny little teen bitch." Then he switched back to his pleasant father voice said, "Why don't you go see if your mother needs any help getting ready? I still have a few things to organize downstairs."
Dad had spent the past few days doing something in the basement family room. It was off limits to me so I had no idea what. It was sure taking some effort. I went upstairs to my parents' room and found Mom naked except for a black garter belt. She was pulling on a bustier over her large forty-year-old tits. "Hi, Sweetie. Good timing. Can you do me up?"
I went around and pulled the black Lycra tight at her back. At the snap of each clasp, mom's relaxed posture began to stiffen. Her shoulders squared up and by the time I was done, my normally gentle and sweet mother had transformed. She turned around to face me. The woman who had always loved me only as mother do, was gone, replace by a sexy and stern dominatrix. My dominatrix.
"That's a good pet." She said as she grabbed a short leather strap from the bed and then sat down. She spread her legs, "Before I let you put my panties on, come here and eat my mommy-pussy. Get me warmed up for what is going to happen tonight to you tonight."
I was instantly on my knees between her thighs. "I'm very excited, Mo... I mean, Mistress. Who is coming over? At least tell me if it is a man or a woman." A cross look replaced her smile. Uh-oh. I had overstepped. I had forgotten myself because of my nervous anticipation for the evening ahead.
My mommy-mistress roughly pulled the front of my sundress off my shoulders exposing my young breasts. They were way smaller than mom's, more than an A-cup, but only just.
She twisted one nipple and then lashed my other young tit with the black leather strap. I could feel my panties getting wetter at the stinging in my breasts. "I would punish you more if I didn't know how much you are already going to get tonight. "No more insolence. Now start using that mouth of yours like a good slut-daughter."
"Yes, Mommy-Mistress." I lowered my face and began happily eating my mother's delicious cunt. I just love her pussy! Her labia is much meatier than mine. I'm a bit of an outie but Mom's lips actually hang down! Amazing. They feel so good in my mouth.
I sucked on her piss flaps for a while and then began to work my tongue on her clit. I had only been having sex with my parent for three months, since the night of my eighteenth birthday, but I had become very proficient at getting my mother off. She often came home from work and had me eat her to orgasm before she went upstairs to have a shower. She preferred me eating her cunt when it wasn't perfectly clean. A couple of times she had me do it when she got back from the gym and hadn't yet showered. Those times made me feel dirtier which made me cum harder when Daddy finally got home and fucked me. It didn't take long before Mom was moaning and oozing her amazing mommy juice into my mouth.
"Show it to me, my little depraved pet," she said huskily. I stuck out my juice-coated tongue. Mommy caught her breath. For some reason Mom and Dad both loved seeing their cum slathered over my young tongue. Dad had even taken some closeup pictures that he printed out and put up on their bedroom wall. I closed my mouth and savored the taste of mother for a moment and then swallowed it down. So good!
Mom pushed me out of the way and started putting on a light makeup. Then she had me slide a pair of black sheer panties up her toned legs and over her round ass. I was tempted to pull the underwear back down and bury my nose between her heavenly ass cheeks when the doorbell rang. Mom looked at the clock, "Right on time. Pet, go answer the door."
With butterflies in my stomach, I ran out of the room to see who was going to join our naughty sex games, but Mom called me back. She took something from her top drawer and then fastened it around my neck. A black leather dog collar. In the mirror it took a second to register the meaning of the backward words printed on it: CUM SLUT. Oh, my god. I fuckin' loved it. Mom kissed me hard on the mouth and fondled my tits. "This is going to be another step in your training, my young slut-daughter. Answer the door."
To say I was shocked is an understatement. I stood in the doorway, braless in an almost see-through dress, wearing very damp panties and a collar that plainly revealed my perverted desires looking at... my grandparents.
"Um...Nanna, Grampy. What are you doing here?" I tried to nonchalantly turn the dog collar, so the incriminating words weren't facing them. Nanna smiled and hugged me, as did my grandfather. They were both in their early sixties and in great shape. Nanna had retired from teaching high-school four or five years earlier and Grampy was still working at the small financing company he owned. They had often been mistaken for my parents when I was younger when they took me to swim lessons.
"Your parents invited us over for a drink. We didn't know you would be here. What a lovely surprise." As she was saying this, she noticed that I wasn't wearing a bra. Then she looked up at the dog collar, thankfully with the nasty words out of view. A strange, almost fearful look came over her face.
"Hello there old-timers." Mom had come into the foyer. She was wearing a bathrobe that concealed her dominatrix outfit. Thank god!
"Mom, I think Nanna and Grampy got the nights mixed up." As I said this, I noticed my grandfather looking at my nipples poking through my thin sundress. I self-consciously put my right hand on my left shoulder, so my arm covered my breasts.
