the crystal was an average size. Lisa closed her now lime-green eyes and sat down. looking down she saw her skirt was tented completely up. it kept rising. the red tip reached up to 2 and a half feet.
it dribbled pre-cum down its massive length. its girth was 2 feet thick. she then grunted as 2 bowling ball-sized testicles pooped into a scaly sack. creme white scales covered it. she instinctively rubbed it.
cum shot out of it like a geyser. she was so into it she didn't see a camera recording her. nor did she realize Dr. Jones was no longer in the room. her skirt was going down. this was not due to her cock going soft.
in fact, it was her height that was increasing. she was 5'5 but now she kept growing. the cream fur stopped on her inner thigh and went up. her once neatly trimmed bush changed. it thickened and turned red.
her waist expanded to accommodate her new cock. it now looked like it belonged. she had to lean forward as the chair was hurting her rear. the reason was snaking up and over the back. her new tail was long and thick.
reddish brown scales covered the top and creme scales covered the bottom. her ass became pure muscle. her new tail broke the seat. this caused Lisa to fall to the floor. her new scales were incredibly durable.
in fact, she barely notice. she now sat in a small dent on the linoleum floor. she could feel each of her abdominal muscles. her newly formed 6-pack was quite impressive. a treasure trail appeared on it as he cumed.
his thighs were now large as tree trunks. the scales now passed her knees. her torso then expanded. his new v shape tore his clothes off. this left only an opened lab coat.
her breasts shrunk after a few more thrusts. his pecs the bulged out. thick chest hair soon covered them. he lost a toe as his feet grew. his feet are now a size 17.
his nails darkened as they became large sharp claws. red fur grew under his armpits. his shoulders are now huge. he would have to enter into a room sideways. his arms ballooned with muscle as reddish brown scales covered them.
his hands followed his feet. his fingers grew rough as his nails became claws. his neck then thickened as an adams apple grew on it. his teeth became sharp fangs as his face stretched. his ears turning their small holes.
his head hair went from blond to red. it then shrunk to a wild short haired look. Lumos opened his eyes. his cum coated the floor. it took a bit of effort but he was able to get up.
he found his height was now 8'11. his head barely missing the ceiling. looking at his body he saw it. he had the body of a T-Rex mixed with the king of bodybuilders. Dr. Jones then entered the room.
"from what I gathered you might want a new name." she said to the T-Rex anthro. "yes I think Lumos would do. it was a fantasy character played as once." he said. it was ironic too.
when he was a teenager he played as an anthro reptile names Lumos. "let's run some tests then you can go. You're gonna have to tell your family" Jones said. Lumos could smell female cum from her private area. Jones took the camera off its mount.
"this will help figure out what happens. sorry for not asking permission" she apologized. "it is OK." he said. "but I want to do a test of my own for that" he approached her.
this was not uncommon. the instinct to mate was in every victim. the ones who got hit with the yellow crystal most of all. "let's keep this experiment to us" Jones said as she undressed. Lumos plunges his cock into the cheetahs pussy.
the large genitals seemed to be able to take on the full length of anyone. she could feel the Dino balls slapping her ass. they kissed as they did so. soon he came and filled her with his cum. they lay there till the test was needed.
