Vera was sitting in the living room armchair with a magazine open in her lap, completely ignoring the shuddering form of her baby sister tied up on the floor beside her.
Ella, her sister, was seven years younger than her, making her eighteen. She resembled their mother, the same pale skin, blue eyes, blonde hair, full lips, round tits, perky ass.
Ella had her wrists tied to her ankles, her calves tied to her thighs, and a ball gag in her mouth, her legs spread apart as far as they could comfortably go. Inside her dripping wet sex was a vibrator, one that was linked to the remote in Vera’s hand.
Vera would continually play with the setting, faster or slower, for different periods of time, the gag muffling all of Ella’s moans.
Vera turned the vibrator on its highest setting, from one to one hundred, she had never turned it up that high on Ella yet. So when it skipped from practically nothing to a hundred miles per minute right against her g-spot Ella was screaming as her orgasm ripped through her.
Vera smiled down at her sister, watching as her cum dropped out across her thighs and the floor, the drool run out of her mouth, tears run down her cheeks. The vibrator was off now, and Ella couldn’t decide weather she wanted the relentless teasing back or not.
Vera glanced at her watch and smiled. Two hours. She had spent two hours edging and ignoring Ella as she begged to cum. And that resulted in Ella’s hardest orgasm ever.
Vera left Ella on the floor as she walked off towards the kitchen. She brought back her dog, a big black Great Dane she named Max.
Ella frowned in confusion around the gag. She didn’t understand why the dog was there. Vera told him to sit and she started to untie Ella. She pulled Ella to the footrest and bent her over it, securing her wrists to each leg as well as her knees.
Ella’s pussy was exposed to the cold air now and she could turn her head enough to see Vera anymore. Then she felt the ottoman shift as Max jumped up, lining up his cock with her opening and forcing himself in.
Ella screamed and screamed at the intrusion and ruthless pounding. She had never been stretched this wide, gone this deep. Then Max stilled and she was screaming hall over again as his knot swelled and forced its way inside her, stretching her impossibly wider.
Ella came three times on Max’s cock, though she would never admit it felt that good to be fucked by an animal. Vera knelt down behind her and licked up the mixture of both hers and Max’s cum.
Vera slapped her ass and left her there, wandering off to do whatever. Ella was fucked by Max a total of four more times the rest of the day and into the night before Vera came to retrieve her the next morning.
Vera didn’t untie her though, she stuck the vibe back in her ruined cunt and they started all over again.
