With paper towels, a bottle of water in my hands, and a vibrator remote in my shorts pocket, I returned through the small part of the hallway, connecting the main entrance with my Sister's room, the kitchen, and the living room.
Turning to my left after entering the large living room, I reentered the stage for my wildest sexual fantasy that had become a reality.
Approaching the table, I saw my Mom from the back, her heeled, thigh-high stocking-covered legs spread and her ankles tied to the table's legs.
Her expensive-looking black dress barely covered her round ass, and the laced top of her stockings glanced from underneath. Her hands tied behind her back with a black nylon rope and poking out above her ass.
Her upper body was resting on the table.
From behind, I could see the straps of the black harness ballgag around Mom's head and her long, tightly woven braid lying on the table beside her.
Mom was looking at my Sister a little further down the long, dark brown, sturdy, wooden diner table.
My Sister was tied in a strict hogtie, lying on her stomach facing my mother, with her ankles, wrists, and ponytail tied together behind her back. She was forced to arch her back in an uncomfortable angle.
The rope around her ponytail forced her head into an upright position, and her mouth was filled with cloth trapped by a white bandana around her head.
My Sister's petite and ballet-toned body was only covered by a white laced push-up bra and a short white skirt that I had pushed up to her waist, exposing her incredibly tight bare ass and her waxed pussy. Her legs were bent and covered in white kneesock that reached up just above her knee.
Her tied feet in white sneakers had Cathy's white thong dangling down from the restraint around her ankles.
I heard the soft humming of the two-headed, U-shaped vibrator I had inserted into my Sister before I went to the kitchen.
Just as I reached my Sister, standing next to the table she was tied upon, I saw and heard Cathy reach her first orgasm from the constant and relentless stimulation she was helplessly exposed to.
I picked up the digital camera from the table and captured this moment in a series of photos.
My Sister forced loud, high-pitched moans into the cloth inside her mouth, which came out muffled and distorted from under the white bandana holding it inside her mouth.
I watched on as my Sister's body slowly relaxed from the arching and twitching as the orgasm washed over her and reduced the vibrations inside her holes one by one to zero.
I undid the rope, pulling at the back of her ponytail, and helped her rest her head on the table as her body's tension gave out.
I wrapped the loose rope around her wrists and ankle ropes to reinforce her hogtie and further entangled her thong into the ropes.
I looked at Mom; she was smiling around her ballgag and looking at her daughter as she recovered from her intense orgasm. A small puddle of saliva had formed underneath Mom's chin from the drool dripping from her ballgaged mouth.
"You turn, Mom," I said, grinning from my teeth.
Mom eagerly nodded her harnessed head.
I walked around the table until I had my Mom's ass before my bulked shorts. I lifted her dress to expose her ass.
Her laced body merged into a thong stripe at the lower back and disappeared down between her round jiggly ass cheeks and around over her pussy where it closed the body with three small snap buttons.
Two laced garter straps dug their way down along both my mother's ass cheeks and held up the delicate black stockings she wore.
I opened the three snap buttons in her crotch and pulled the thong stripe out from between my Mom's ass, and tucked it under the lace backside of the body on her lower back. I did the same with the front part and reached below to tuck it in the front at her lower stomach.
I reached beside my Mom for the camera, pushing my bulk between her naked asscheeks. Mom moaned through her gag from feeling my erect penis against her exposed labia.
I snapped some pictures of moms naked ass and some close-ups of her puffy labia glistering from her juices.
I took a step back to include my hogtied Sister's arms and legs behind Mom's naked backside. Mom's breathing picked up in anticipation of what might happen next.
I reached for my sports bag to take out a butt plug. I chose the second biggest one for Mom's more experienced rectum.
I took the lube from the table and squirted some onto my fingers. I brought my fingers to Mom's holes and started rubbing them along her exposed anus. Dipping my index finger inside her rectum and massaging her pussy entrance with my thumb.
Mom's muffled moaning picked up instantly.
Releasing my fingers, I applied lube to the plug and slid it slowly into my Mom's ass. I saw how she relaxed her anus and tried to welcome the plug inside her. With a careful push and the spades-shaped plug got sucked into her ass, leaving the round colorless gemstone sparkling in the ceiling spotlights above her pussy.
Mom hummed in her gag over getting something up her ass.
I removed my shirt, grabbed the remote from my pocket, and stepped out of my shorts.
Just in my black boxers, I reached down into my bag to take out the black floppy leather paddle and placed it next to Mom's plugged and bent-over ass on the table.
I was almost ready to finally fuck Mom.
But before, I wanted to play with my Sister some more.
I moved back over to my hogtied Sister while stroking my cock inside my boxers.
She looked up at me, still resting her head on the table, and then down to my hand in my boxers.
With my other hand, I turned the vibrator in my sisters's holes back on. I set it to one of six.
Cathy hummed enjoyably into her gag over the readded stimulation.
I removed the white bandana from her head and pulled the black cloth out of her mouth. The fabric was drenched in her saliva.
I threw it on the empty part of the table behind my Sister, where it landed with a splat.
"Fuck bro, that orgasm was intense; thanks for getting me off." My Sister said chipperly while she turned her head to look at my face.
"It was hot seeing you come, Sis. And good lord, your ass is the hottest thing I've ever seen in my life." I replied while still holding my cock.
"Thanks, Bro; it has seen a lot of squats." Cathy smiled.
My Sister put her head back on the table and looked straight at the dick in my hand inside my boxers.
"Want me to suck you off before you fuck Mom?" Cathy asked with a smile.
"And that's the hottest question I've ever heard." I laughed while pulling down my boxers.
"Stick it in my mouth then, let me suck that gorgeous cock of yours." My Sister said, opening her mouth.
