When punana was allowed to look at itself after several weeks of recovery, it broke down crying and they had to sedate it. The Doctor had replaced pun...na's vagina with a mare's vagina. It slips were big, loose, dark brown and swollen and the passage was deeper and wider than it had been before. punana cried for days. it was no longer fit for humans or even dogs, its vagina was much too loose for a normal sized cock. punana would spend the rest of its life fucking horses. Tiffany and the Doctor. The tension meter showed a clean graph and Arianna was in a trance. They kept this up for another couple hours till the artificial cervix just completely gave out.Mark was exhausted but Arianna was ecstatic. She wanted to run home and process the data she’d collected. She turned to Mark to thank him and saw how tucker out he was. He had been helpful throughout the process and Arianna figured she owed him big. She walked over to the chair he was in. Before Mark had realized what she was doing. I bounced on his cock with my eyes shut from the pleasure I was feeling.Then I heard a familiar voice tone and opened my eyes. I was still grinding on cock but looking to where that voice came from. It was my Sally on her knees and sucking the jizz out of another girl’s used cunt. Then I looked closer to see that Tirophy’s smartass friend was fucking her from behind. I should have realized by the way she was moaning, that she was getting a good fucking. My inner thoughts were distracting. By now a small circle of spectators had formed around us. A woman, (mid thirties?) stood immediately in front of me, her fingers making long lazy strokes along her slit. Daniela removed the soiled condom and placed my limp cock in her mouth. It started to swell almost immediately her tongue set to work. Meanwhile her friend was busy in her slit with fingers and tongue. The girls were both playing to the gallery and enjoying it but held it at arms reach. Anyone who came to close was.
