Ensign Andrew entered the forest. It was actually a holodeck. But it looked, felt, smelled & sounded all real. Ensign Andrew ordered the holodeck to lock & not unlocked except with his voice command. The door locked & disappeared into trees & stuff. Andrew began to undress already feeling the pressure & squeezings. And 'it'. Andrew got totally naked & put his clothes & everything in a hollowed out tree stump. His second bag he released some rabbits & the like which disappeared into the forest. For the week they would be 'it's' food. He then ordered that the opening on it be deleted. Immediately the opening on the tree stump disappeared. Andrew felt like he couldn't hold 'it' back much longer. His body wanted to change. Had To Change. Ensign Andrew was a weredinosaur. Something akin to a velociraptor. That's what 'it' is. Andrew had hidden what he is from the academy & everyone else almost all his life. His dinosaur self. He created this forest holodeck program a long time ago for his other self. He's taken it with him from starship to starship. He has remained an Ensign so he could let 'it' out every month for a week. No one really cared about ensigns. No one would miss him for a week each month. All of Andrew's body hair sucked into his body leaving him totally bald. This was followed by the painful sucking off his penis & balls into his body as they turned from human to reptilian. Andrew could already feel the velociraptor in him wanting to take over as his bellybutton & nipples disappeared. He felt the first of the painful pops as his body truly began it's transformation from human into dinosaur. His ears shrank away becoming only ear holes on his head. Andrew's fingers & toes started to shift popping & cracking painfully as they did. Andrew's teeth became sharp. 'It' was clawing at the mental walls of his mind. The velociraptor was a beast of simple needs & thoughts. A predatory animal. It wanted to push Andrew aside. It wanted full control. Andrew feared always that the dinosaur would kill someone. This is why he locked it in a holodeck forest. A nub began to form above Andrew's butt which would become a tail; a butt that was painfully shifting. Andrew knew he couldn't hold the dinosaur back any longer. Andrew let go. It instantly took over pushing Andrew's mind away. Into a dark corner of his mind. This is where Andrew's human mind would rest. His eyes became yellowish & reptilian as the pupils slitted. The creature began to groan & moan in pain as the flood gates released. The transformation into a dinosaur was unstoppable now. The velociraptor was coming back again.
