Anne can't do it

"She's my sister! Emma... No!... Just... Just let her go, and I'll do whatever you need, I'll... Suck it... I... Don't you want that...?"

Seeing her sexy girlfriend begging to suck her cock was definitely a thrill for Emma, but she had no intention of letting Kelly get away either. Slipping free of the the older sister's slit, Emma stalked towards Anne. For a moment, Anne felt relief that her plan had worked, only for this to be replaced by fear of her lust maddened girlfriend and her terrible new shaft. Anne stumbled back towards the sofa, scared by the hunger and cruelty in her lover's eyes.

As Emma reached Anne, she shoved her backwards on to the sofa. Seizing one of Anne's hands she roughly pushed it between the trembling woman's own thighs. Leaning in close, her breath hot on Anne's neck, she whispered intently "If you won't do it, then sit there and play with your little cunt while you watch me give your filthy little whore of a sister the fucking I've always wanted to."

Kelly hadn't managed to clear her brain in the few moments of reprieve, so was entirely unprepared when Emma returned and unceremoniously rammed her cock back inside. Emma reveled in the groan of pain this drew. Her hands gripped Kelly's hips, holding them still whilst Emma **** herself in to the hilt. She rocked her own hips, making the fat length of meat stretch every part of Kelly's cunt. Whimpers of pain met her exploration of the older girl's depths, but not enough to satisfy Emma.

Emma dragged her victim off the table, her cock still embedded. Kelly's head and shoulders crashed to the floor as she found herself folded over, Emma's hands hauling the black bra over her tits at the same time. Emma's length slid free of Kelly until just the head remained in her entrance. She waited for Kelly's eye to meet hers then, patiently. When they did, she used her position to pile-drive every inch of her fuck-stick into the other woman's pussy. Kelly's eyes bulged and she hung in silence for a moment before a wail of agony was ripped from her. With a hard slap to Kelly's jiggling tits, Emma pulled free and lunged again. Each thrust drew a fresh cry of pain from her victim and finished with the crack of flesh on flesh as Emma made Kelly's tits shudder with swat after swat.
