ask a girl to fist Katy's pussy

"You'll get some more fingers!" I say develsihly smiling. "Hey you can you come over here and give Katy your fingers?" I ask a girl that stares at her cunt. "Sure!" she replies.

She pushes two fingers in Katy's pussy and I remove mine. She adds a third finger. finally she's rocking four finger in Katy's pussy. "Can you fist her cunt?" I ask the girl. She looks up to Katy. Katy just nods to show that's OK. The girl moves her fingers in past her knuckles. She makes a fist and slips it very slowly and carefully into Katy's wet hole.

Slowly Katy's pussy stretches around the fist. The girl moves her fist wrist deep into Katy and a tries to push further. Katy bites her lips and breathes deeply. The girl starts to rock her fist in Katy's cunt what makes Katy gasp and moan. I feel the girls fist on my fingers in Katy's ass. "Fist-fuck me! Yes, oh my god. It feels incredible!"

After some minutes Katy is heavily breathing, she's close to an orgasm.
