Randall turned and left, but forgot to turn the lights off.
Jenny turned her head so that she could see Megan. They had strapped her back down to the table but left her arms free. Jenny could see that Megan was playing with her tits with one hand while pumping the other in and out of her pussy as fast as she can. After a few seconds she orgasmed so hard she seemed to come up off the table a little bit.
During the peak of the orgasm Megan changed alittle bit. Jenny could see that her ears were larger and slightly flopped over at the tips and she could see 3 more sets of nipples starting to form down Megan's stomach.
Over the next few hours Megan brought herself to orgasm several more times, each time changing a little bit more. After a while the door opened back up and Randall walked back in with Thomas.
"The chemicals should have been fully integrated with the dog DNA after 30 minutes of the first DNA 'donation' doctor" Thomas said with a smile, "At this point introducing more DNA wont matter."
They walked over to Megan looking her over. She was fully covered in a soft, light brown fur with 4 sets of DD tits. Her mouth and nose had pushed out into a small muzzle and her ears had become large floppy dog ears. She had a short tail and her feet were fully changed into paws.
"Good, her hands didn't change much, aside from the fur on them and thicker, darker skin on the palms" Randall commented "She will still be able to work for her new master." He then unstrapped Megan.
Rolling her over so that she was laying on her stomach with her legs hanging off the side. Smiling Randall pulled her legs slightly apart and pushed his finger into her dripping pussy.
"She seems to be ready" he laughed as he dropped his pants and slowly slid his cock into Megan. She began whimpering in pleasure as he thrust into her.
Jenny quickly looked away not wanting to watch as her friend was being raped, even if she apparently liked it so much. After a few seconds she could feel herself getting aroused from the sound. As she got wetter and wetter she found herself watching again. Just as Randall shot a load deep into Megan's womb, Jenny let out a quiet moan of pleasure and Thomas noticed her for the first time since entering the room.
Walking over to her he stuck his finger into her pussy and she screamed in pleasure.
Laughing he turned back to Randall "She is ready for Phase 2 doctor..."
