Spike had explained to John the one other way he could make him immortal, and now, as they kneel on John's plush bed, naked and caressing, they were ready to initiate a mating claim.
John picked his spot with great care, deciding to demolish Drusilla's siring mark with his own mark.
Spike closed his eyes, moaning breathlessly as John's teeth latched onto his neck. It hurt, especially since John was attempting to break his skin with blunt, human teeth, but the pain parlayed so well into pleasure. "John," he gasped as his lover's teeth finally sunk into his flesh.
John swallowed the blood that swelled in his mouth and whispered against Spike's neck. "I, John Hart, claim you as my mate. You're mine."
"Yours. God, John, I'm yours. Forever." Spike slipped into him vampire mask.
"So beautiful," John murmured, kissing him, cutting his tongue against his fangs as the kiss deepened.
Spike couldn't get enough of John's blood. It tasted amazing. More addictive than sire's blood, even slayers. He realized it must be the claim that did it.
"Claim me, Spike, please," John whimpered.
Spike complied, sliding his fangs easily into John's neck, creating his own mark. He drew a mouthful of blood before whispering his own claim. "I, William Pratt, claim you as my mate. You are mine. Always."
"Yes I'm yours, Spike." John moaned. Spike knew exactly what to do with his fangs. Just how to stir the most amazing sensations through his worldly, and other worldly talents. John wrapped his hand around both Spike's, as well as his own painfully hard erections, and slowly moved his hips.
Spike's hand joined his, and they moved together; their thrusts uninhibited, eased by the copious amounts of pre-cum.
"Oh god, John," Spike moaned grabbing the back of John's neck with free hand, and kissing him softly.
John couldn't remember such tenderness. He knew, finally, what it meant to make love. Soft movements, soft caresses, soft kisses. There was no other name for it.
"I love you. Love you so much, Spike." John buried his face into his neck. "Mine," He mumbled into his neck.
"I know. I love you too." He moaned, his motions faltering as he approach his climax. "Yours. God I'm yours, John."
The two clung to each other as pleasure washed over them. They cried out, strangled versions of each other's names. They collapsed onto the bed in a tangle of limbs.
Spike nuzzled the mark he made on John's neck. His mating claim.
John followed suit and nuzzled Spike's neck. "So, this is like a vampire marriage?" John asked.
"I guess. More profound, though. We'll start developing skills. We'll hear each other's thoughts, feel each other's emotions, and sensations. Cheating isn't possible."
John kissed along Spike's jaw. "Well now, that'll irritate Buffy, and Jack... probably not Angel though," he joked. "Guess no more threesomes?"
"Please, vampires have been claimed and participated in orgies. As long as we're together, and we want it, the claim will accept it without trouble."
John stroked his fingers down Spike's chest. "I don't have any problems with an occasional threesome. You're mine though." He lavished Spike nipple with attention from his tongue.
Spike moaned softly. "Yeah, John, I'm yours."
John grinned. "Good. Now, back to my earlier train of thought. If this is a marriage, will you finally move in with me?"
Spike chuckled, pulling John on top of his chest. "Yes, I'll move in."
John pressed a chaste kiss to his lips. "Good. You'll make a wonderful wife."
"I thought we agreed that you were the wife?" Spike raised his eyebrow.
"I do believe our conversation was cut short. We never decided."
"Fine then, how about we argue this later, and now we nap?"
John chuckled, resting his head on Spike's chest. "Nap, shag, eat, then argue, then shag again."
Both slipped into sleep, holding each other. One from a far off future, the other from the long since pass, both utterly in love, and both finally in the point in time they belong.
