Erin takes control

It happens so fast you don't even notice it. You can't even be sure how it happened, as if you'd looked away and looked back. But you didn't you've been watching Donna and Erin this whole time.

And yet, suddenly Erin has one hand gripping Donna's short hair atop her head, and the other, sliding down Donna's torso and curling two fingers into her wet cunt.

"Fuck you bitch!" Erin is suddenly wide-eyed and wild. "If you're not going to tell me what happens next, then I'm going to decide."

Donna barely objects. She's lost all control of the situation and is currently melting onto your girlfriend's fingers. She attempts to speak "I'm... I'm in contr..." but is stopped by the sensation of Erin's spit hitting her right in her eye.

You wonder if Erin no longer wants to be your nastiest fuck pig. Or maybe she does, just in a different, slightly less submissive way. "Naughty girl." She says through gritted teeth, "pretending to be a bitch, when you can't resist being a fuck pig."

Donna struggles to get away, but not with much effort, as if she's struggling because you told her to be dominant, but she really prefers this.

Erin stops her by slipping a third finger into her slit. Donna's lip trembles.

"I saw you with my man," Erin insists. "I know what you really want to be. You can pretend to dominate me all you want. But you're not happy unless you're someone's worthless slut, are you?" You've never seen Erin quite like this. Not even close. Donna doesn't answer. "I bet you'll never be happier than when you're down on your knees, like you were this morning, worshiping all those cocks."

Donna doesn't answer. So Erin slides a fourth finger into her. Donna's mouth drops, and she attempts to make a noise, but no noise will come.

"Answer me!" Erin shouts, spitting on Donna again.

"No" Donna finally squeaks out.

"Never happier?" Erin's breasts heave with excitement. She's never treated anyone like this before.
Donna shakes her head. "Because without all that cock..."

"I'm worthless." Donna answers, her tough exterior, tattoos, piercings, punk hair, not looking so tough now.

Finally Erin slides her hand out of Donna's twat, examines her goo-covered fingers, then with a smile, wipes them down Donna's face. Donna's whole body trembles. And Erin shoves it to the ground.

"Well I'm going to show you what it's like to feel even more worthless." Erin gets on her knees, straddling Donna's head, on knee on each side, her pussy pointed directly at Donna's pretty face. And she starts to rub herself. "A man will thank you for sucking his cock, and for wearing his cum. He may think you're a whore, but a whore has value." She closes her eyes and rubs herself harder, harder, faster. You've never seen her this filled with pleasure before. She's truly finding herself, not as a submissive, but a the most degrading of dominants.

This is an interesting turn of events.

"To a woman..." She goes on. "You're nothing but a rag... a rag for her cunt to squirt on." And then, as if timed out perfectly, she squirts a gushing load onto Donna's face. Donna shakes and shivers. She licks her lips, trying to taste it all.

Panting, Erin climbs off. She looks at you with proud eyes. You nod your head. You're proud of her too. "Maybe instead of ten guys cumming on her every morning, she needs ten girls." You say, watching Erin's smile grown and her ears perk up. "Where do you think we'd find ten willing girls?"
