She flinched, feeling it scurry along. What was that thing?

Sharp little feet scratched through the binding web without damaging it as the spider skittered up Severity's body. It settled on her feet for a moment, then jabbed something sharp past the encasing threads and into the girl. Pain flashed for a moment, about as strong as the hardest of the blows from the crop, and rapidly subsided before slowly ebbing waves of cottony numbness.

She cried out softly, her back arching. "What did it do?" she asked, terrified.

"Hmm?" the gray woman asked, tilting her head. "I'm sorry, that must be incredibly difficult to talk through. Snip snip?" The scissors dipped against Severity's skin again and cut away a thin band to free her lips, though the wrappings around her throat would still impede her speech somewhat.
The creature skittered to her other foot and injected her again, sending another flash of pain followed by slow waves of numbing. The first leg was without feeling below the knee and the spread was starting to slow slightly.

She breathed as deeply as she could as the wrappings were removed. "What is it doing?" she asked tremulously, craning her neck to try and see the little mechanical spider.

"Oh, I should have guessed," Steel said, her face split wide with a cruel grin. "It's preparing you for feeding, of course." The anesthetic had spread completely along Severity's legs by the time the scratch of small legs reached over her belly and up onto one of the girl's breasts. It paused there as the gray woman rotated herself in the air. Her crotch hung now before the girl's face, and hands quickly undid the shorts covering it to reveal a dark, thick shaft.
"If you're a good little cocksucker, I won't let it continue."

Without even pausing to think about it, Severity opened her mouth wide, trying to reach the rod. She tried to swing herself, but found that the numbing was spreading too fast.Desperately, she craned her neck forward as the spider crept onto her breast.

The spreading numbness slowed and stopped just below Severity's crotch. The shaft drove hard into her mouth, filling it roughly, as Steel's hands settled on the back of her neck to guide her in a slow bobbing motion.
"That's a good girl. Suck nice and deep to remind me why you shouldn't be spider food."

Severity gagged slightly, but quickly managed to get used to it, sucking as hard as she could. After a few minutes, she managed to get it most of the way in. "Mmm!" she said, relaxing her throat muscles a bit.

Steel chuckled and thrust her hips slowly just as the girl was getting used to the length of the member in her mouth. The spider skittered quickly across her body and back towards Severity's covered slit and began wriggling underneath the webbing.

Her eyes widened as she almost choked. Howver, she quickly got use to the size, and kept on sucking away. As she felt the spider slip through the webbing, she flinched.

The creature burrowed only a bit further into the webbing before pressing a cold metal head against her folds. As she cock in the girl's mouth slid forward, a cool, smooth shaft suddenly burrowed into her folds.
"Ahh, it's hungry for something else, I see."

She squirmed, feeling it slide in. At the intrusion, she began sucking harder. She didn't know quite was was entering her tender passageway, but whatever it was was turning her on.

Whatever it was, it began thrusting slowly in and out of her and bending against her inner walls despite the spider remaining still. The shaft in her mouth leaked a small drop of seed against her tongue as it slid back and forth.

Severity redoubled her efforts, tasting the first few drops. When she tried to swallow, she realized that she couldn't due to her position.
