Going deep

Mia continues working her fist in and out of Tracy's ass which affords a chorus of moans and groans from the slut. After a few minutes of the twins making love in this sick and twisted way, you encourage them on further.

"Go deeper whore."

"Yes Daddy."

At your instruction, Mia starts working her fist in deeper and deeper into Tracy's ass with each thrust. After some time of struggling to force her fist in as deep as it'll go, you're shocked to see that she's all the way up to her forearm in her sister.

"Oh fuuuuck." Tracy cries out.

"How does it feel slut?" You ask.

"Soooo good." She moans out with her eyes closed and a face of ecstasy.

"I told you."

"My ass feels so full! I can feel her so deep inside me."

"Take your arm out whore. And slut, get on your back."

"Yes sir." "Yes Daddy."

The two girls get into position with Tracy lying on her back on the couch and Mia kneeling on the floor at her rear end.

"Go deep inside her again."

Mia does as you instruct and slides her whole forearm back inside her sister's asshole. With Tracy stretched out as much as she is, it doesn't take too much time or effort. With Tracy on her back like this, you can see Mia's arm sliding around inside her belly.

"Oh my god. That's so fucking hot." Mia gasps as she sees her own arm moving around inside her sister.

"Ohh fuck." Tracy gasps out, tilting her head back in ecstasy before returning to watching her sisters fist moving around inside her with perverted eyes.
