Xander gasped as the two demons headed towards him, and ran away as fast as he could. The demons rushed after him but stopped dead in their tracks as the boy reached Buffy, just as she dusted a vampire. The evil creatures knew she was the Slayer and that they were in deadly danger, so they turned tail and ran. Xander asked her friend to follow him without further explanation and dashed in pursuit of the demons. Buffy was faster. She grabbed one, sent him flying through the air and then pinned the other one to the floor. She plunged her stake in his heart then did the same thing to the other demon.

"Aaaaaaaaaaaaaaaa!" Xander yelled in sheer panic.

Buffy turned around and froze, seeing an almost naked Xander lying on the ground with a naked caveman on top of him. She didn't recognize Giles and raised her stake before running towards them.

"Noooo! Don't kill him! It's Giles!" Xander cried out when he saw his friend ready to kill the caveman. "No! No! I'm fine… l'm a little crushed by Cave-Giles' weight but I'm okay. I… Oh Geez!"

Giles-caveman was now straddling his waist and roamed his large hands over his shoulders and chest while sniffing and licking at his neck. He could feel the caveman's huge penis pressing against his stomach and his massive testicles resting on his pubis. He was immediately and violently aroused and Cave-Giles noticed it. He ignored it, though, to touch Xander's smooth flesh reverently, circling his nipples, tracing his musculature over his ribs, outlining his collarbone.

[It's the first time he's seen… a modern man. And he seems to find me to his taste.] Xander thought, seeing amazement in Cave-Giles' eyes.

Cave-Giles bent to take a small brown nub into his mouth and he nipped it before sucking on it. Xander uttered low groaning noises, which pleased the Neanderthal man, primal desire shining in his eyes.

Buffy stared at the primitive creature straddling Xander's waist, astounded. It was some time before she was able to speak again, and she croaked "Cave-Giles?"

Xander gave a long sigh. "The caveman is Giles, Buffy. That's why I told you not to kill him. One of the demons clawed him and he immediately morphed into Neanderthal man. You know like Dr. Banner morphs in Hulk…"

Buffy blinked, amazed. "Huh?"

The boy gasped when cave-Giles tore his briefs open. He yelped then when the prehistoric man grabbed his engorged member to examine it. Buffy flushed in embarrassment and turned around.

"Err… Giles seems to still love you very much, Xander. Do you think he's still himself in his head?"

Xander shook his head. "No I don't think so. His brain has probably de-evolved too, Buffy. He doesn't know me, and he doesn't know you. He doesn't know where he is, etc. He's a 100% prehistoric man!… apparently strongly attracted by me… "

"Gaaarh hagas ogaa!" Cave-Giles said with a guttural voice before nuzzling Xander's groin, sniffing the musky scent of his arousal.

He rolled Xander on his stomach and stroked his buttocks, which he kissed then and nibbled, causing the younger man to writhe under his touch. He then parted them to reveal the puckered entrance to Xander's body. Cave-Giles reached out, raised the boy stomach off the ground and placed him on all fours. He eased a finger inside his lover, making him gasp then knelt behind the boy and pressed the head of his massive cock against the anus. Xander struggled to free himself from Cave-Giles grip. He didn't want to be ripped open by his huge cock. He managed to roll over and grasped the prehistoric man's erection and started short and hard strokes. Cave-Giles' eyes dilated and he groaned deeply in pleasure, captured Xander's head between his palms and brought his face towards his very hairy groin.

"Raaah tomumma gabal!"

[Translation: suck me!] Xander thought.

Buffy cleared her throat, still embarrassed. "Er… Xander, do you still need my help?"

"No."

"Good!… I'm going to take the shovel from the trunk of Giles' car. I need to bury the demons' bodies."

"Hem. Take your time Buffy."

"Sure."

On that note she left, running, totally freaked out. In the meantime, Xander had swept his tongue around the head of Cave-Giles' penis and underneath the engorged shaft, amazed by its size, both in length and width. He tried to forget his need to have the huge member ramming inside him deep and hard (but only once having been previously, carefully and slowly prepared, and the member copiously oiled), but he found that impossible. He felt himself grow even more erect at the thought of having the other man enter him. His ass wanted to be filled, his prostate to be hit again and again until he reached a powerful climax. He unconsciously waved his hips from left to right, the muscles in his ass clenching and unclenching with hunger. Cave-Giles noticed it, understood Xander's need and once again placed the boy on his elbows and knees. This time Xander stayed submissive (it was a first for him since Giles and he became lovers). He hurried to prepare himself the best he could with pre- cum-coated fingers and waited for the prehistoric Giles to fuck him in a feral way, trembling with apprehension: it was going to be painful.

[But the pain will disappear, to be replaced by pleasure really quickly.] He thought, trying to reassure himself.

Xander cried out in exquisite delight as he felt the sudden pressure against his anus. Cave-Giles grasped the boy's hips firmly, holding him steadily as the snub touch became insistent pressure. Xander's head arched back involuntarily as his body fought the continuous penetration. Eyes closed, panting and writhing he dug his fingers in the ground as the head of the caveman's cock pushed steadily inside him. He breathed deeply and cringed from the pain when the blunt tip finally breached his body.

Cave-Giles pulled back and a second later pushed forward again. He repeated the action until he was half way in. Then he withdrew, keeping only the head of his penis inside the rectum, leaving Xander aching to be filled again. Xander ground his hips back against the caveman's throbbing penis, inviting more. In one powerful move, cave- Giles thrust forward. Xander, his eyes watering, screamed as he felt his anal walls stretch uncomfortably, then grunted as the huge shaft slid relentlessly into his rectum. He managed to relax and the pain disappeared, almost. It still hurt around his asshole, but not any more than it already had. His body had finally accepted the foreign invader.

"Oh, Geez," Xander gasped with a shuddering breath. "It's so good! You're so * big * !"

Once he was fully inside Xander, Cave-Giles pulled back and his withdrawal was followed by a slight change of angle. He slammed back inside Xander, and went deep and stayed deep, rocking his hips, angling to find his partner's prostate, rubbing sleekly over it eliciting howls of pleasure from his partner. Cave-Giles repeated his movements, rotating his hips so that with every slam he hit the boy's prostate slightly differently. He began to pump helplessly and senseless as his desire begged to be relieved causing Xander no end of pain and pleasure, sliding that semen coated cock up his insides only to withdraw again and continue pounding him over and over. Xander was arching his back, pressing himself against the caveman's hardness, driving it deeper inside and eliciting hoarse cries from Cave-Giles. With uncontrollable enthusiasm, Xander threw himself again and again, moaning continuously against the rock hard penis, which rose again and again to fill him, climbing higher and higher to a huge climax. He wanted, needed, and craved this wonderful, agonizing, bittersweet pain. He had placed one hand on his own hard cock and was stroking himself in time to Cave-Giles very powerful thrusts, his breath coming in faster and faster gasps. He thrashed wildly as he felt the muscles within him seizing Cave-Giles' cock again and again.

With each savage, pulsing thrust the prehistoric man approached his release too. He was pleased to hear the pale, smooth, frail and so lovely creature he impaled with a hard driving rhythm, moaning, gasping, crying and screaming. He was pleased too that his mate was submissive. He needed to dominate, must be dominant. It was in his nature. Obviously it was in the white-man to be dominated and he really appreciated that.

Cave-Giles reached out and grasped the boy's burning erection. With his lover's cock in hand, he stroked the weeping cock in time to his thrusts. He heard Xander groan deep down in his throat, as his balls tensed up under his calloused hand, getting ready to explode. Knowing that he himself couldn't last much longer, he sped up faster still and leaned forward and bit Xander's neck hard, making him yelp in pain and come with a hoarse cry. Cave-Giles climaxed too, pushed over the edge by the contractions of his mate's ass. He collapsed onto Xander's back, the boy flopping flat onto the ground underneath him. He quickly recovered and pulled Xander, who had passed out, into his arms, hugging him possessively. He then hoisted him in his shoulders and headed off.

An hour and a half later, Buffy came back to the demon's bodies, a shovel in her hand (she had gone to dust other vampires in Green Park Cemetery, letting Cave-Giles and Xander have sex). The corpses were on the ground where they had fallen, but there were no signs of the two guys. Worried, she searched for them and discovered large, deep footprints in the grass (she deduced from them that Giles was holding Xander, who had probably passed out) and they led her to the main gate of the cemetery. After that, she lost track of them on the pavement.
