As the front door opened, Claire called to her daughter to help her bring in the groceries. She had returned from shopping sooner than expected and the girl did not answer. Her daughter, Judy, struggled to move away from sucking Kate's cunt, but Helen's relentless pounding of her anal passage with a large dildo made it impossible for her to move. Judy was beginning to panic, she knew her mother would be demented with rage at finding her and her two cousins', Kate and Helen, engaged in lesbian sex, but neither Kate nor Helen seemed the slightest bit perturbed. As Claire entered the room and took in the scene before her, Kate took hold of Judy's hair and forced her face harder against her cunt. Claire's temper exploded and she screamed at her nieces to stop at once. Helen meekly withdrew the dildo from Judy's arse and just seemed to melt into the background.
Claire gazed at Kate still enjoying the eager attentions of the common slut between her legs, inwardly Claire recognised her daughter as the slut but her mind rejected the obvious as she stared at the gaping hole that was once a tight anus and the girl's dripping cunt. Claire walked over to the slut and began to spank her arse as hard as she could. Kate was elated; the added stimulus brought her to a massive orgasm. Juice flooded from her, squirting into Judy's face and hair. Claire was apoplectic with rage and as she moved to drag the slut from between her niece's legs, Helen's arms encircled her, locking her aunt's arms to her sides, Helen's anal dildo pressing hard into the cheeks of Claire's arse. Holding her aunt upright, they watched as Kate slowly regained her composure, still holding Judy's head firmly to her cunt.
Eventually Kate said, "Ah aunty dearest, I am glad you have joined this family get together!" As she said this, she twisted Judy's face towards her mother. Claire stared at her daughter, cum literally dripping from her mouth, chin and nose. Claire screamed but Kate only laughed and ordered Judy to kneel in front of Claire. As Judy crawled towards her mother, Kate slowly approached, safe in the knowledge that the powerful Helen restrained her. Kate looked closely at her aunt before kissing her lips. Claire clamped her lips closed, but Kate reached up and closing her nostrils, waited for Claire to open her mouth. Claire had no option and as she opened her mouth to gulp in air, Kate's mouth closed on hers and Kate's tongue energetically probed her mouth. Kate knew she was well passed the point of no return and was excited that her aunt's humiliation had begun.
Kate stepped back and repeatedly spat into Claire's face, saying, "You're my slut now!" Kate smiling moved forward, grabbed her aunt's hair, and forced their lips together. Kate pushed her knee between her aunt's legs and started to rub her aunt's pubic mound with her hand. Kate's hand pressed hard into Claire's mound and her fingers pushed even harder towards her aunt's cunt. Kate soon sensed Claire's growing acceptance and gradually she inched Claire's straight skirt higher and higher, revealing Claire's sexy underwear, garter belt and stockings. Kate, an evil sensation building inside her, forced her hand underneath Claire's panties and began to stroke, caress and pinch Claire's exposed cunt lips and clit.
Kate was an expert at fingering the clitoris and although Claire's cunt appeared slick from jism, her aunt's juices were not flowing. Kate used all her expertise and soon she felt her aunt's juices start to run from her cunt. Claire was determined not to orgasm but slowly she realised that her orgasm was inevitable. Claire although doing her best to hide her impending orgasm, suddenly capitulated and opened her lips and sucked Kate's tongue into her mouth, their tongues began caressing each other, in a dance of sexual intimacy. Claire's breathing was getting quicker and shallower, she was starting to quiver and eventually she shook uncontrollably as waves of pleasure surged through her body, seemingly emanating from Kate's fingers.
Kate withdrew her fingers and played them over Claire's lips. Claire instantly commenced licking and sucking her own cunt juices, tainted with jism, from her niece's fingers. Claire, her skirt around her waist, spread her legs wide and bent her knees, enthusiastically rubbing her cunt on Kate's thigh.
Kate smiled at her aunt and said, "I am your Mistress and you are my slave!"
Claire moaned as a second orgasm started to build, but Kate said sternly, "I am your Mistress and you are my slave!"
Claire who was now frantically humping her niece's leg would do anything to orgasm, begged, "Please, please Mistress, please let me cum!"
Kate only asked, "You promise to do your mistress's bidding in all things?"
Even more desperate, Claire replied to her niece, "I promise to do whatever my Mistress tells her slave to do."
Kate knew her aunt was broken and removing her leg, she placed her hand onto her aunt's clit. She toyed with the nub, pulling, twisting and caressing it before ramming four fingers into her cunt, her thumb pressing hard against the clit. Claire exploded and a torrent of fluid squirted from her cunt. Claire's daughter and niece watched as Claire trembled uncontrollably, screaming with pleasure, Kate's hand buried in her cunt almost to the wrist.
As Claire regained her self-control, Kate ripped her panties off, saying, "Slaves never wear panties!"
Kate holding the panties in front of Claire's face noticed that the panties were wet with jism that had leaked from Claire's anus and she struck her aunt's face punctuating her words as she yelled, "You dirty fuck slut," slap, "you have allowed your arse" slap "to be fucked" slap.
Claire remained silent, but Kate again slapped her face and then grabbed her tits and squeezing as hard as she could, she yelled, "Tell your Mistress, Slave!"
Claire whimpered and nodded.
Kate laughed, but did not release Claire's tits, instead she said, "I did not hear you!"
Claire nodded again and whispered, "Yes" but Kate looked at her menacingly, and letting go of one tit she raised a clenched fist.
