Cautiously, Greg opened the door to Matt's room. It was slightly ajar when he arrived. Matt had sounded really weird on the phone. Greg peered into the room calling softly, "Matt? Matt, are you still here? Matt?"
He cautiously stepped into the cobweb filled room. It looked like something out of Arachnophobia. He let the door go, and suddenly it slammed shut. Greg didn't see the long black spider leg reach down from the ceiling to give the door a shove. He moved toward the unmoving lump in Matt's bed. He reached down and shook it. It felt kinda soft like pillows sort of, so he pulled back the covers and was surprised to find a dummy woven out of silk threads.
"What gives?" he asked as a silken lasso dropped over his head and pulled tight around his neck.
The giant spider swung down like Tarzan and jumped on to Greg's back. He was on the floor down on all fours, and the long black arms had woven a silken harness to his face. The silken bit acted as a gag or muzzle.
"Mmmmgggrft!" was the muffled noise that emitted from Matt's hapless captive.
The spider continued to slip silky threads over and under Greg's arms, legs, neck and chest. Greg tried to buck the giant spider off, but it was really no contest. After about 3 minutes, Greg found himself hanging from Matt's bedposts with his wrists ankles and head firmly bound. The silk cocoon on his head resembled a ski mask with openings for his eyes and nose only. The monstrous spider then turned its fangs on Greg's clothing. A rip here, a rip there, and soon Greg was naked from the knees up and his nipples down. The spider began to gently play with his tits, and then turned its attention to his exposed cock and balls. The advantage of having eight limbs was that Matt could attack Greg's nipples, genitals, and anus simultaneously while adjusting its own egg pouch to receive Greg's hardening prick.
To his horror the spider rose up over him drawing itself up one of the webs hanging from the ceiling. It hovered over him while still toying with its back legs with his hard oozing cock. He couldn't help but gasp into his gag that he hoped the monster would let him come soon.
Whether Matt understood or not, he lowered his open abdomen oozing with a sea of silvery eggs on to Greg's erection. Matt then began moving up and down, and Greg started to moan...Greg screamed into his gag as his cum spewed forth inside the monster. Matt let out a screechy clicking sound apparently signalling its climax also.
Greg hung limply sweating and terrified as the black shiny monster riding his cock closed its wet gooey opening and moved to lay its hairy carapace on top of his torso. The eight gleaming eyes stared into Greg's two green ones, and the mandibles opened to rip Greg's gag from his lips, and to Greg's shock it spoke.
"Well, Greg, looks like you're going to be a father, and me a mother. Who'd have thought it?"
"Matt? Is that you?" Greg gasped, and then said, "Father, ew?"
"Yes, Greg, it's me. I thought you'd make the perfect mate, and I was right. Pity, we spiders eat our mates," Matt said leaning in to french kiss the bound father of its mites.
Greg's scream was muffled by the hairy spider head pressed against him. Steel like mandibles injected Matt's caustic venom into Greg's tongue. Greg zoned out, lying there with his mouth hanging open, and his lips turning black, while Matt finished wrapping him for dinner.
