The dark skeleton’s hand paused. He had to stop writing as one of his tentacles flicked. Nightmare had not flicked it himself. Sometimes this happened. He lost control of his own corruption and it did whatever it pleased. He placed the pen down on the desk. He knew better than to write when his tentacles were like this. He’d learned from last time.
He inhaled quietly. He closed his eye and tried to pull them back under his control. He had work to do and this would slow him down greatly. He furrowed his brow, only to shiver as one of his tentacles slipped into the top of his sweater, wiggling down against his neck. Another slipped between his legs, sliding easily into the waistband of his shorts.
He jerked a little in his chair. His bony fingers dug into the armrests and he forced himself to remain quiet. If he seemed uninterested, the tentacles would stop. He’d managed to stop them like that once before. Unfortunately, they seemed to have learned. The one in his shorts wrapped around the front of his pelvis, rubbing it. His legs shook.
The last two tentacles made their way down and curled around his femurs, both forcing his legs to open all the way. The tentacle in his shirt appeared out the bottom, beginning to pull it up. Nightmare inhaled sharply. He reached up and grabbed his tentacle, forcing it to stop. “I have work to do!” He hissed. The tentacle flicked in his hand.
The one around his pelvis gave a tough grind and Nightmare gasped, his face heating up. They all seemed to wiggle and Nightmare swore internally, knowing they were excited now. He drew in another shaking inhale. The tentacle in his hand lunged forward, forcing itself past his jaws and making its way into his throat. Nightmare choked and the shock overwhelmed him.
He lost control and his ecto began to form, the tentacles all becoming heavily excited. Nightmare was trying to breathe around his own appendage, his eye wide. He was beginning to tear up. He was still overwhelmed and his ecto reacted as such. It formed everything. From his breasts to his cock. He made a noise of protest as his tentacles pulled his shorts down to his ankles. They still wouldn’t let him get up.
His tentacles didn’t seem to mind the ecto, immediately beginning to explore the new areas. Nightmare reached up and tried to pull the tentacle out of his mouth, only for two more tentacles to form from his back and slam his wrists back down against the armrests. He jerked. One tentacle slipped between his breasts, coiling around both of them. It gave them a squeeze and it was rewarded with a muffled groan.
Another had coiled around Nightmare’s cock while the last had slipped up against his folds, rubbing in between them. Nightmare’s thighs twitched as two more newly formed appendages forced them open again. Nightmare arched his back. His head was forced back as the tentacle in his mouth slowly began to thrust. The one at his entrance was rubbing in time with the thrusts.
Nightmare let out a weak moan, his body shaking. His breasts were squeezed again and he trembled, gasping. The tentacle pushed inside of his entrance without warning and he jerked, his thighs still forced wide open. He let out a loud, muffled moan, tears welling in his eyesocket. The tentacle under him began to thrust and Nightmare cried out again.
He was desperately trying to remember if he’d locked the door. He knew his crew would knock… MOST of his crew would knock. He screwed his eyes shut. He’d only ever told Dream his tentacles did this. He’d scoffed at the idea that he might be pent up and frustrated, but it didn’t seem as ridiculous now. He let out a soft shriek as the tentacle inside him pushed deeper, practically inside his womb.
His eye was wide. The tentacle pulled itself out of his mouth and he kept his jaws open for air. It was a mistake. The tentacle inside him began to thrust mercilessly, making him shriek and the sound deteriorated into a loud moan. He leaned forward, shaking as his breasts were squeezed, along with his cock. A flash caught his eye.
He couldn’t look away now. He stared at himself tearfully in the mirror. “Fuck…” He whimpered. He couldn’t see what was happening beneath, but he could see himself being wrecked by his own appendages. The first tear escaped down his face and he grit his teeth. Something thin slipped over the tip of his cock and he froze up.
He didn’t have time to react before the tendril was inside, pushing its way into his cock. Nightmare screamed, finally hunched against the desk. He moaned as the tendril in his cock and the tentacle in his entrance began to thrust and he wailed. His fingers dug into the armrests, his wrists still pinned. He was shaking and overstimulated.
“Pl-Please! F-Fuck!! Ah!!” He was loud and too overwhelmed to care as he broke loose. The tentacles seemed to like that. He wanted to cum. He was already crying. He opened his jaws but couldn’t get the words out. He tried to buck his hips in an effort to dislodge the tendril, but it did no good. “P-Please…! C-Cum!! L-Let me c-cum!!” He begged tearfully.
There was a moment of nothing before the tendril thrusted DEEP before suddenly yanking itself out and Nightmare screamed as he came, his cum coating his chair and the underside of his desk. He shook violently, slumped over the desk. He realized something. None of the tentacles were loosening. It seemed he was in for a long night.
