Somewhere in Restfield cemetery

Xander dropped his stake on the ground and suddenly pinned Giles against the wall of the burial vault and kissed him, hard. The Watcher gasped under the aggression and let his battleaxe fall to the ground. Xander then cupped the back of his lover's head and the Watcher parted his lips permitting access to the boy, allowing him to delve into the depths of his mouth. Their tongues met and duelled for dominance for some seconds, until Xander bit the older man's lower lip hard to show him he wanted control.

"I thought we had agreed to play the Master/Slave roles only when at home, Xander."

Xander nodded. "Yes, but I'm addicted to being the `alpha male' now, and I want to be your Master everywhere. But don't worry, only when you and I are alone together. I don't want to shock the guys by fucking you in front of them. And that would be the height of bad manners!"

Giles chuckled. "Your vocabulary is improving in my company, Xander, I'm pleased to note."

"Of course, with you speaking a so perfect `englishish English'. Except when I made love to you. You talk dirty, then. So Giles! Are you willing to be submissive outside of the house too? But with no one around us?"

"I'm yours. Take me." Giles said before licking away the blood welling from his lower lip.

Xander growled like a wild beast and all rational thought fled, leaving him a primal creature with only one instinct coming to the fore, the need to couple with his mate, to merge with the other half of his soul. He moved his mouth to Giles' throat, sucking and nipping with his teeth, leaving marks as he did, marking the smooth skin. He started thrusting his hips hard against his lover's, grinding their erections together. Then Xander's hands moved to undo Giles' tie, slipping it from under his collar and throwing it over his shoulder. He wrenched his lover's shirt open, not noticing or caring that buttons were torn off, flying everywhere. Once Giles' chest was bare, Xander caressed the soft pale skin, enjoying the play of muscle under his touch. He ran his fingers through the greying chest hair thinking his Giles was so virile as he watched Giles' face, his eyes hooded with desire, his breath coming in heaving gasps.

[Yes! He's * my * Giles. Mine, mine, mine!]

"I so * want * you, Giles! I'm going to * fuck * you hard and deep, again and again."

Giles groaned deep in his throat needing to be held, to be touched, to be filled, and be consumed until there was nothing left of either of them. "Yes, yes, make me scream, luv!"

"Call me Master, sex slave."

"Yes, my Master."

Xander continued to touch Giles' broad hairy chest reverently [beautiful, so beautiful] he thought, circling his nipples, tracing his musculature over his ribs, outlining his collarbone. He bent and fastened his mouth over one of Giles' nipples, nipping it with his teeth before licking and kissing the sensitive nub to hardened arousal. Giles squirmed and cried out. Xander then turned his attention to its twin, which he licked and sucked to painful hardness. Meanwhile, his hands snaked down to the waistband of his lover's pants. They undid them and pulled them down, taking the boxers underneath with them. Then one hand reached back and down to tickle the soft scrotal sac. He could feel the balls twitch as he did it. He lifted then the sensitive testicles, and rolled them. He stroked the delicate skin beneath while with his other hand he grasped the fully erect penis.

Giles moaned loudly, as the boy began to masturbate his long, thick shaft, licking his lips.

"Place your hands on your head and spread your legs, slave! Don't move and don't talk until I give you the order to."

Giles nodded. "Yes, my Master."

He complied and lowered his eyes to see Xander kneeling on the ground between his parted legs. The young man wrapped his fingers around the base of his lover's eager member, lowered his head and sucked gently on just the crown while fondling the base of the steely penis. Slowly he took more of the massive shaft into his mouth, tonguing it, sucking it hard now, and loving the feel against his lips, loving the friction, loving * his * Giles. Giles hissed at the sensation of being taken into that hot, wet mouth. He smiled contentedly. He really adored being sucked off by the boy, his Master. As every inch of his throbbing cock was sucked and licked, Giles could only moan out loud at the exquisite pleasure he was nearly drowning in. He closed his eyes in bliss and had to fight to control himself. He was not allowed to move. He so wanted to buck his hips, to thrust into the moistness of Xander's loving mouth. Xander looked up and was impressed. His lover managed to stay still, except for the slight tremor running through his whole body. It was acceptable. Pulling back, he smiled up at Giles. He looked as if he were in agony.

"Good slave!" he stated.

Xander swiped his tongue up the underside of Giles' rigid member a couple of times with hard strokes, and dragged the hot shaft into his mouth. Then he started sucking Giles' cock again, enjoying the older man's moans and groans and the taste of the hot, satiny skin. He reached out and pressed his fingers against Giles' perineum before moving back and circling his puckered entrance.

"Oooooh! Awwww!" Giles uttered, shaken by spasms, arching his back up, opening and closing his hands frenziedly.

Xander let his lover's steely shaft slip from his mouth and looked up at him again, sternly. "You moved! You're going to be severely punished! I'm not going to prepare you."

Giles accepted this, trembling in anticipation. Xander stripped off his own clothes quickly, then closed his hand over his engorged penis. He began stroking up and down the shaft, his thumb rubbing over the tip and down spreading pre-ejaculate with every stroke, coating and lubricating the rigid shaft with it. He then took a firm hold on his lovers' hips, holding him steadily as he pressed against the tight opening. Giles bent his knees slightly, presenting a willing target. He then arched back and closed his eyes involuntarily as his body fought the steady penetration. Xander groaned in pleasure as he felt the ring of muscle trying to resist and pushed a little harder. He took his time, pushing forward and easing back, until the head finally slid inside. He eased forward a bit more then pulled back, only to ease forward again. Giles cried out in pain yet pushed back to meet the next plunge. Xander repeated the action until he was completely embedded. The Watcher moaned as he adjusted to his lover's considerable size, his tight passage clenching around him.

"How do you want it, slave? Slow and teasing or hard and fast?" Xander asked Giles.

"Hard and fast, my Master, because vampires or demons could come and surprise us in this position and take advantage of it to hurt us and perhaps kill us."

Xander nodded. "Mmmm… you're right. So I'm going to fuck you hard and fast, slave."

"Oh yessss, my Master!"

Xander started to thrust firmly into his lover, steady strokes that set Giles' prostate on fire. After a minute he thrust harder, faster and deeper into him. Both were gasping for air, both completely lost in their lovemaking, in each other, and so didn't see the two demons heading towards them. Xander tried to hold back as long as he could, but knew that the end was getting nearer. Giles had his front pressed against the wall and used the friction of the contact to climax. He arched, stiffened and came, spraying semen all over the white stones. His released triggered Xander's. He thrashed his head back and forth as the erotic pleasure tightened in his trembling limbs and stomach. He had time to thrust once more and heard Giles' gasping, shuddering cry as he exploded himself, bucking and shuddering against his lover's rigid hips. He slowly withdrew on legs trembling from the explosion of his orgasm and saw Giles turn around, lost in a post coital haze. With still trembling arms, he pulled the older man into a tight embrace.

"I love you, Giles."

"Mmmpfff… "

Xander grinned. "You may speak now." He then frowned when he noticed Giles' eyes widened in fear. He immediately turned around to see two very menacing looking demons, green, with horns, running towards them.

"Oh shit!" he said.

Xander pulled his briefs up then picked up his stake. Giles pulled his boxers up and grabbed his battleaxe. The two men were ready to fight as the two evil creatures attacked them, but their lovemaking had exhausted them and the demons rapidly and quickly disarmed them. Giles howled as long, sharp claws tore his right arm open from shoulder to wrist, and he crumpled to the ground.

"Run, Xander!" Giles croaked, his face contorted in pain. "Find… Buffy. Go! Go!"

Xander shook his head. "I can't abandon you! Giles I… Oh my God! OH MY GOD!"

The boy's eyes widened in shock, and then in horror when he saw his lover begin to morph. Giles flesh swelled up, his skin stretching, his bones cracked, hair began to cover his whole body, then huge muscles began appearing, as he grew taller and stronger. His boxers ripped in the process. His face was the last to be transformed and changed into a primitive one. Xander blinked hard, astounded and shocked: his lover had de-evolved into a caveman.
