She nodded to Brent the doorman seated at the reception desk. Sandra pushed the up button, waited as the elevator dial moved downward. Taking a quick look over, she noticed Brent was concentrating on the CCTV display. The elevator opened just then and she got in and pressed 5. There was a slight shaking as the car ascended. A soft voice from the back of the car jarred her temporarily, "good afternoon Sandra". Sandra turned around, it was Mr Morgan from down the hall. A fiftyish man with salt and pepper hair ,rugged facial features, like a real cowboy ,thought Sandra. A trim form in a fleece gym suit. "Good morning Mr Morgan". "How are you and your mother getting along?". "Just great, Thanks we are both well and you?". "Couldn't be better, say hello to your Mom for me". "Will do, Mother said she'd have you over for dinner one night" "That would be great, you know where I am". The door opened, Sandra said "bye" turned right and headed for # 514. Turning her key in the lock she put her carryall bag on the foyer floor ,hung up her coat and removed her high heels, leaving them under her coat. Walking into the living room she noticed the TV was on but no one was watching. Heading down the hall to her room as she stole a glance into her Mother's room. Livia Smith was naked laying face down on the bed , her large breasts were splayed out beneath her. Sandra noticed Livia still had a bit of tan left from their Brazilian vacation a month ago. An exquisite rear Sandra thought. Livia squirmed a bit and adjusted a pillow under her tummy, which made her derriere Jut upwards. Sandra's Mom's legs were spread wide. Sandra heard a noise to her right and a young man with a small goatee and short hair climbed on the bed behind Livia got on his knees and positioned himself between her outstretched legs. He was wearing shorts only, was about 5' 9', Sandra noticed the growing Bulge in his shorts. A muffled growl from Livia "Get going Harmon" . Harmon respectfully replied "Yes Miss Livia", and rested his hands on each side of Livia's tanned buttocks. Harmon lowered his head ,his tongue snaked out as he separated Livia's beautiful round cheeks. He licked Livia's crack on both sides of the crevice and then headed for her perfectly round rosebud. Inserting the tip, Livia sighed and wiggled her bum a bit to tell Harmon to go deeper. Catching her breath Sandra said to her Mom, " Mom I'll turn off the Television" Livia turned her head to speak , " that would be fine, Thanks dear" and had a quick look back at Harmon Who had his left hand in his shorts and smiled. Sandra turned off the TV and went back to her Mom's room, Livia was moving her ass slightly with Harmon's ministrations. Livia placed her left hand on the back of Harmon's head to push him deeper between her cheeks Sandra noticed Harmon's ears were red at the tips, she could hardly see his face, most of it was buried in Livia's crack. "Saw Mr Morgan on my way up, I mentioned dinner" Livia turned her head toward Sandra, " This Friday is good Darling give him a call" between breaths. "I'm a bit busy right now". "Ok Mom". Sandra checked the white pages and dialed Lee Morgan's number. She recognized his relaxed voice when he answered. "Hi Mr Morgan, Sandra here, is this Friday good, around 6:30 for dinner?" "That would be fine Sandra see you then" Sandra hung up, just as the intercom buzzed. "Hello Brent" "Marla Amparre has an appointment with Ms Livia Smith" Brent sounded out of breath. "Send her on up", this could get interesting Sandra thought. A little later, opening the door to a blonde girl about 17, in a red tight fitting track suit holding a small red leather bag. She had a close cropped haircut, deep blue eyes, rather pretty. "Mrs Livia Smith?" Sandra noticed her shapely figure, her breasts jutted out as if defying gravity. "She's in the other room," Marla Amparre, I'm also a bit late" she said with a hint of a smile. "Sandra Smith, Livia's daughter". "My brother Harmon should be here". Sandra pointed to her Mom's bedroom," He's in there with Mom now". Sandra followed Marla into Livia's room. Livia was groaning into the pillow and moving her rear in a forward and back motion, her back a light sheen of sweat. Sandra thought, might be on the verge of an orgasm. Harmon was doing his best not to lose his target. Marla was removing her track suit. Sandra noticed Marla's killer boobs, round, actually slightly oval with large puffy aureoles,nipples hard. Marla was strapping on a huge red dildo, an 8 incher and thick, she looked up at Sandra and smiled as the heavy breathing emanated from the bed. Nice smile Sandra thought, even nicer form, especially her heart shaped butt with dimples, thought Sandra as Marla turned to face the action. "OK Harmon my turn" Marla announced. "OK Harmon my turn" Finally Harmon removed his face from Livia's lovely behind. He looked a bit dazed, his face was slightly red and moist, the head of his cock peeking out of his pant leg. Marla climbed up on the bed as Livia turned her head and watched, not moving. Marla knelt where Harmon had been, moved the head of the big red dildo around Livia's crack using the juices to make it moist. She then got closer inserting just the tip into Livia's anus. Livia raised her legs at the knee and placed her feet on Marla's ass cheeks pushing her forward. Livia grunted as the red cock slid in and Marla laid on Livia's sweaty back. Marla's tits splayed out on Livia's back as she began to move back and forth in Livia's moist asshole. Harmon in the meantime had removed his shorts and was standing behind Marla. Marla, stopped and looked back at Harmon. "Hop aboard brother" Harmon knelt behind Marla, moved the strap on Marla's ass crack over to the side and pressed the tip of his tumescent erection to her sphincter and pushed forward slowly but steadily. Marla Sighed. Sister and brother then began synchronized ass fucking.
