Chapter 605: Operation Screwing - Stage 2 (Final) R-18

On the table, the second Dr. Kiba lay with Stina mounting him in a classic cowgirl position, her mouth hanging open before the cock of first Dr. Kiba.

The second doctor spread her ass cheeks and exposed her back door for the easy access of the third doctor. 

"I never had anal sex!" Stina got out of her trance and spoke. 

She didn't dare think she could handle an enormous cock down there, not the size of Dr. NTR, and certainly not a double penetration.

Just having her pussy jammed by the second doctor had given her multiple orgasms. 

Double penetration would kill her!

"Relax. As your doctor, I know you have great untapped potential."

The first doctor said while grabbing his cock and positioning it towards her face, rubbing it on her cheek. 

"N-no! I'm not even lubed there!" Stina hastily said. 

"Ah!" The first doctor nodded in understanding.

His figure blurred, and he swapped position with the third doctor.
