Black advanced penis-first on the waiting female, took hold of one arm and breast, dropped onto her torso and issued a pneumatic sigh. "Just let me dip my stick in your transmission, black baby," he said.

She shimmered—and Black found himself embracing a crocodile. Great and green and alligator-hided, with a thrashing tail and elongated snout and cruel hungry eyes.

Prior, watching, was as dismayed as Black. There, but for the grace of circumstance and a flaccid member, went he! He had known the demons could change shape, but this was ridiculous!

Black, whatever his political sentiments, was sexually normal. Bestiality was hardly in his line, when he considered it degrading to sample the lubricity of even nonblack human females. Prior saw the ebony penis losing elevation as it brushed the cold belly-scales of the reptile. A luscious woman-form was one thing, demon though she might be; this was something else.

But there was no release from that embrace. The crocodile's immense jaws whipped around, snapped at Black's face—

But Black had brought up his wrist with the amulet. A blue spark jumped, singeing the reptile's teeth. "No kissin', cousin!" Black cried. "You can't hurt me. I got protection!"

"Human bastard!" the crocodile muttered, licking the charred surface of the tooth. "Think you're pretty mortal smart!" And it changed into a monstrous crab. "Well I'll just pinch you to see if you're real!"

Two gigantic pincers reached for the man. One went for the throat, and Black had to fend it off immediately with the amulet.

The other pincer moved simultaneously for his groin, and Black, distracted by the threat to his neck, didn't catch it in time. It clamped on the genitalia and wrenched—and suddenly Black was a bleeding eunuch. He screamed once, horribly, then fainted.

Prior was appalled, sickened, and terrified, but also angry. The foul-mouthed Negro was his friend in his black-humor fashion. Black had twice summoned cherry branches for him to tackle individually, and had once thrown him a penis when he had been caught short. Last time Black had given him the life-saving hint about the Demon's nose—the facial aperture without deadly teeth. And Black had gotten them safely here by summoning the hellephant.

Yes, Black was a friend in deed and sometimes in word. Prior knew he could not have made it this far without the man's timely assistance. Black didn't deserve such mutilation and death, when all he had wanted was a decent dusky fuck.

The crab metamorphosed back into the crocodile, and the crocodile opened her jaws to take another bite of manflesh. The dripping penis and scrotum lay on the cold cavern floor, the blood melting into the cherry ice.

Prior charged.

If he had had time to think it through properly, he would have known he had no chance, and let the Negro's corpse buy him time to escape. He would have given up his insanely foolish quest for the Spire. He would have returned to Earth a sadder but more potent man.

But now rage drove out all fear and all reason. His six-incher was not even rigid, but he tensed his legs to pounce on the crocodile.

His foot slipped on the severed, peeled-banana penis. A testicle squirted out from under as Prior fought for balance. He couldn't stop; he had to fall, so he fell forward.

And landed astride a tigress. Literally.

"Another lover, so soon!" she purred, her predator-muscles orienting on him. "Well here's some real pussy for you, half-mast!"

She twisted off Black and faced Prior, the deadly sharp claws of all four feet driving for his gut. But he still had some of the advantage of surprise; she was not properly braced for his impact, and the floor was slippery with diluted blood on the ice. He crashed into her bodily and shoved her sidewise, away from Black.

Instinctively he wrapped his arms about her torso, pulling her tight to restrict those scraping claws. And then she was an enormous fat hen. "Squa-awk!" she squawked. "Let's have some cock!"

He tried to wring her small neck, but the clumsy bird became an unclumsy bird: a giant eagle, its bill stabbing down at his eyeballs.

There was hardly time to react, let alone think. Prior butted his head against hers, using his hard skull to blunt her sharp beak, and reached out wildly for Black's body. There was sharp pain in his skull as hair and skin were gouged, but he found the body. While he fought off the buffeting eagle's wings one-handed he wrestled with the Negro's body for that magic amulet. It was set in a bracelet, and if he could get it off—well, he could take the punishment of claw and beak for a little while, so long as he got hold of that protection.

Meanwhile his opponent had changed her shape again. A man-sized hairy spider threw loops of sticky web about him while purple mandibles came at his face. But he got hold of Black's arm, slid along the wrist, hooked a finger under the band. As the spider's venom-dripping jaws opened to damp on his nose, he hauled desperately on amulet and hand, and brought it between him and the demoness. The spark jumped again.

"Now cut that out!" the spider said, jerking back while its face-fur smoked. Its six or ten eyes blinked in pain. "I'm just trying to offer you a little good hair-pie." But already she was a shark, with seemingly endless teeth.

"There's something fishy about you," Prior grated. He put the amulet right into that underslung maw and drove it back. He had a weapon now—but he knew it could not win the battle for him by itself. It had not been enough for poor Black! He used it to fend her off while he concentrated desperately on his definitive weapon: his penis. He could only vanquish her completely by copulating with her—and it had to be fast, or he was dead, amulet or no.

But it was hard to stiffen his torpid member in the face of these repeated changes of form! Now the bitch was a bear, now a snake, now a pig. Each form constituted a new attack by claw, fang or snout, and none was sexually conducive. And he sorely missed the semen he had so recently expended on the assless demon. An amulet was no substitute for ejaculate!

Nevertheless the heat of combat elevated his blood pressure, and his member gradually came erect. The abrasion it received during the struggle helped, though there was little sexual appeal in this. As his penis hardened, the demoness lost strength, for here was the thrusting phallus she most feared. Her scratches became shallow, and her blows futile. Finally she collapsed back into human form.

Prior wedged her luscious thighs apart and forced his full-sized meat into her loosening hole. At least this vagina was ample! He had been half afraid she wouldn't have one. She screamed and went limp.

He had won again!

Except—

Except that he hadn't come yet. And she hadn't puffed into smoke. That was suspicious.

She was playing possum, though she had carefully avoided assuming the possum shape, evidently hoping he'd be satisfied with the seeming victory. She must have known that he couldn't come quickly, so her loose vulva was safe for the time being. If he fell for that ruse, who could guess what deviltry she would come up with once she recovered the initiative?

Prior rammed into her the full six inches, finding no resistance. It was such a contrast to the vicelike tightness of the other female; this one was a cool ocean in her laxity. In fact, he had precious little to strive against, and his penis was freezing!

That was her trap! She was zero weather inside, and his hot blood was rapidly chilling. He had to finish the job promptly, or his flesh would go numb.

He couldn't come. He had to have incentive, stimulation, and friction, and there was no more of these here than might be had by having intercourse with a day-old corpse. In fact she even felt corpselike now—a body in the freezer.
