Matt felt sore all over, and chilled. He started to get out of bed, then changed his mind, and went back to sleep.
The venom must have been an hallucinagen because Matt had the weirdest dreams. He was running and jumping, swinging from threads, and pouncing on giant insects wrapping them in web with his legs, and sucking them dry.
When Matt finally woke again, his body was drenched with sweat. His head must have been hanging over the side of the bed he thought because his hair was hanging upside down. He opened his eyes, and blinked everything was wrong. He focused in, and he was looking down on his bed or up? He shook his head, and saw that his bed was below him and that he was wrapped in thick silk webbing hanging from the ceiling. His sharp head turn caused his whole body to rotate from the web cord hanging from the ceiling. He screamed and clamped his mouth shut when his face rotated in front of the mummified corpse of his room mates poodle hanging from a similar cord.
Matt freaked. He was sure there was a giant spider lurking in the room. The dog had been the apetizer and he was to be the main course. He had to get out of here, he thought, and as he did he spread his legs apart, and the cord attaching him to the ceiling grew longer lowering him to his bed.
"Wha-??"
Matt like a gymnast pulled himself up to examine his crotch. About 3 inches down each thigh was a shiny black curved conical two pronged horn, and the thick silk strand extended from those two spinerettes. He thought down, and watched as this thighs flexed in and out, and more thread spewed out of his spinerettes.
Dropping to his bed, Matt pulled his covers around him and shivered. The dreams! He'd pounced on the poodle, wrapped it in thread, pumped it full of digestive juices, and sucked it dry. But in the dreams there had been more than one insect he'd webbed! He shivered, what if there were other silk wrapped bodies in the apartment. What if his room mate? No, it couldn't be. He should go back to sleep. He'd probably dreamed that too. He lay back on the pillow and saw the dog's blind eyes staring out of the wrapping at him from where it was hanging. He wasn't dreaming.
He got out of bed to investigate.
