"What happened?" Crystal asked as she dodged in and out of traffic on the highway.
"Girl...stole. Tracked her...down...almost-"
"You tapped into your primal? You know you aren't supposed to do that so close to the lunar phases." She scolded.
Damian let a low inhuman growl rumble out from his chest in warning. Crystal couldn't help but feel absolutely aroused by it. A part of her wanted to pull off into a parking lot and fuck him. However she knew better than to antagonize his primal. She hurried home and parked in the driveway and helped him inside and down into the basement.
At the bottom of the stairs was a thick steel door with a large bolt lock on the outside. She twisted and turned the rotating lock and pulled open the door. The basement was something out of a horror movie in appearance. The twenty by thirty foot basement had a fifteen by fifteen slab of concrete in the middle.
Deep thick furrows marred the concrete as though someone had dug long trenches through the cement. Drilled into the concrete at each corner was a thick metal shackle with a short thick chain. The twelve foot tall ceiling looked nearly black in the darkness of the dimly lit room. Crystal helped her brother to the center of the room and started taking off his clothes.
She pulled off his shirt and then his pants and socks until he was stark naked. His muscles flexed and rippled as the primal inside fought for control. Dark green and blue veins spider webbed across his body as he snarled. Hair from his head had grown down along his spine and was quickly growing over the rest of his body.
She could sense her brother's pain but amongst that pain she saw his arousal. A part of her felt guilty but another part felt instantly aroused. She pulled out the camera that Riley had given her and started taking pictures. Some of her brother and some of his cock. Crystal couldn't believe how amazing his cock looked when he was going through his new moon transformation.
It reminded her of a canine penis, all pink and covered in veins; and a human penis with thick girth and a rigid head. Crystal couldn't deny herself the opportunity. She set the camera on record at the edge of the cement and pulled off her clothes and straddled her brother's erect penis.
She leaned into his chest which had started coating over with hair and spread her labia over his cock. When she looked behind her at his testicles she was amazed at how they had shifted. His normally loose but close ball sack and swollen and tightened up to his penis, almost like the thick knot of a canine cock.
"I'm sorry Damian. Don't be angry." She said and slid down onto his raging pink cock and started riding it. She could feel every pulse and throb of his cock as she pressed down onto him. She could feel the tip of his penis drive into her cervix. Crystal felt his tight knot at the bottom of his cock as she slid down onto him.
"Oh my god Damian. This is amazing!" She shouted.
Damian though looked like he was in an agonizing place of hell as he tried to hang onto the last shred of conscious humanity.
Crystal though was too near her climax to realize just how quickly she was pushing her brother over the edge.
She started pounding her pussy with his cock as her orgasm rushed up.
"Oh fuck yes! Oh my god it's incredible. Oh fuck yes! I'm cumming Damian! I'm gonna fucking cum all over your cock!" She shouted and then as she slammed into his cock again, her orgasm rushed up and gushed out and over his cock. That orgasm was enough to break his humanity and allow the primal control.
"Oh shit!" She screamed and rolled off him and slapped the first cuffs onto his wrists. Crystal scrambled for the ankle cuffs and slapped them on just as Damian let loose a predatory howl that no human could replicate. She backed to the door and stopped and watched him. She watched as his skin peeled away like the outer flesh of a snake or the husk of a larva.
His human skin shredded and crumbled away allowing for a very furry beast to take form. Crystal watched as his teeth fell from his mouth and were quickly replaced by rows of ivory fangs. His finger and toe nails broke away and in their place grew long black talons. The sound of his bones breaking and joints popping filled the room.
She watched as he grew from six feet long to eight feet long. His body expanded and filled in with raw muscle covered in fur. His bones broke and healed allowing for his growth. His human face shattered over and over until it no longer resembled anything human, only that of a wolf. So focused on the agonizing transformation Crystal didn't notice Susanne until she was right behind her.
"Don't watch baby." Susanne said and she hugged her daughter. Crystal couldn't help but watch. A part of her felt like she needed to see this. To see her brother shift into the new moon form of his primal essence. Even as she watched her brother painfully turn into a magnificently horrifyingly beautiful creature, her eyes were drawn to his cock.
A bright red fleshy cock which no longer resembled human, in fact there was nothing about him that looked remotely human and with each passing moment, his humanity slipped away further. However she was drawn to his penis, sixteen inches of throbbing red cock which leaked out thick white sperm onto the concrete.
Every drop was the equivalent of an average man's load. A part of her wondered what it would be like to bathe beneath his cock. To feel all that hot cum cover her naked flesh. What she didn't know was that she was not the only one thinking that. Susanne felt guilty for having such erotic thoughts about her son who was suffering more than any living creature deserved to suffer.
Though even with that in mind she couldn't stop watching his thick cock throb out heavy murky white load after load of cum. Susanne wanted to be beneath that shower of sperm and drink it. Cover herself in it and feel it fill her insides up. Susanne couldn't deny how stunning her son was. After nearly five minutes of pain staking transformation, Damian had shifted into his primal essence brought on by the new moon.
Standing eight feet tall and at least twelve feet long from snout to tail, he was a massive black wolf. His eyes and ears twitched and his claws raked at the concrete as he tried to dig himself free. The thick iron chains held him in place, as they would through the night.
Crystal glanced towards the ground and had almost forgotten about the camera she had placed. She had forgotten she had set it on record and it had caught the whole thing.
"C'mon baby. Let's leave him be. He will settle down soon." Susanne said and they walked up the stairs and locked the door.
