"Is there a bigger cock I could fuck her with?"

Alex smiles. "Of course, my slut. Step out of the harness."

Leigh does as she's told while Alex retrieves another dildo. She brings it over, and Leigh notices her mistress can't close her hand all the way around it. It's huge. She hands it to Leigh, who gasps at its weight and settles it into the mount on her harness. She puts it back on and grins madly as she steps back up to Sabrina.

Sabrina is yelling unintelligibly behind her gag. Leigh ignores her and presses the head of her big cock against the blonde's wet cunt. She pushes, Sabrina screams, and she pushes harder. Slowly but surely, she gets the cock inside her bitch, then starts rocking her hips to fuck her. Sabrina's sounds don't stop as she speeds up.

Leigh notices that there are goose bumps all up Sabrina's ass and back. The sounds she's making have changed--still loud, still insistent, but a little more moan and and little less scream. She fucked Sabrina harder and harder. Sabrina reacted to each thrust, shuddering and moaning.

After a few minutes, Sabrina's whole body shakes as she screams long and loud. She throws her head back and squeezes her eyes shut. Leigh slows to a stop, realizing what happened.

"Did...did she just cum?"

Alex smiles. "Sure seems like it."

"But she didn't ask to, did she, sir?"

"She certainly didn't, my pet."
