John does it.

At first he is very reluctant. "Come on Jonny," Zoe said with a cute little pouty face. He gave in and went down to his knees. It was like muscle memory. Once he started it was all too familiar. He kept going and within 1 min was about to cum when Zoe bent down and caught it in her mouth and swallowed like she'd done it a hundred times before. "Woah woah woah!" Zoe yelled. Jon looked up even more turned on than he had been his whole life and a little confused. "No evidence.. duh!" Zoe said "Oh," Jon replied dummly. "That took longer than usual, now I have some things for you to do for me" Zoe said with a huge grin as she whipped off the remaining cum from her face.
