"Dirty cunt!" Thelma hissed, dragging her wet pussy all over Donna's pretty, scummy face. "Dirty little whore! Dirty little slut! I'm going to grind your slutty little ass to pieces!"
Thelma batted Donna's hand out of her cunt and dropped down over her fouled, sexy body. Donna gasped with shock and sickness when Thelma kissed her, smashing her lips hard and driving her tongue deep inside her mouth. She squirmed with horror and delight when Thelma's strong hands closed over her tits and mauled them more roughly than any of her sons had done.
"Scrawny little bitch!" Thelma gasped, trapping one of Donna's long, lean legs between her lush thighs. "My boys really fucked you slutty, didn't they? They're going to be fucking you for a long time, bitch! You'll love that, won't you?"
"Yes!" Donna cried, squirming with lust as Thelma rubbed her knee all over the swampy slit of her cunt. "I loved them fucking me! They all three fucked me at once! I wish they could fuck me forever!"
Thelma fucked her, rubbing her leg over Donna's cunt and dragging her cunt up and down Donna's captive thigh. She bit and kissed and licked her way all over Donna's dirty, beautiful face, not seeming to mind the filth that splotched her creamy skin.
Before long both women were cumming, and Donna clutched at her cruel older sister as though she were hugging the world's sweetest lover. "Pretty little Donna!" Thelma whispered at last. "You finally got your fucking, didn't you? You finally got your dirty little ass fucked right into the dirt!"
"Yes!" Donna gasped, her voice shaking. "In the dirt! Right where I belong! Thank you, Thelma!"
Thelma smiled, knowing that she had made the most beautiful, sexy woman in town her personal slut slave. She pissed again, having to force the piss out this time, but savoring the look of mixed disgust and passion that filled her sister's face. That was a look she wanted to keep seeing for a very long time.
And Donna smiled too, a tiny orgasm quaking through her body as her sister doused her with piss. She was tired and hurt, but she was looking forward to the cocks that were waiting to fuck her, the men who were waiting to hurt her. She deserved everything she was going to get.
And she knew she was going to get everything she deserved.
