Xander was the one solid thing in Spike's unlife that kept him grounded, kept him focussed on reality. Eyes the colour of rich loam soil, hair like shag tobacco, earthy in a way that Spike was not. Even several months of being a vampire hadn't totally bleached his skin. Spike could still find traces of the tan his boy had earned, working every day from dawn to dusk. The scents of earth and fresh cut wood, and the concrete dust he hated, were long gone but Spike occasionally still checked, just in case. Sometimes he missed the silliest little things.
It took Xander quite a while to get used to the 'breathing optional' thing, for weeks he'd break off kisses to gasp for air. Spike just rolled his eyes and called him 'git' and 'daft' and 'wanker' then tugged him back and stole his breath again.
What amazed him was the way that, now he didn't need to breathe it, the air was suddenly so much more. Each breeze caressed his flesh and teased his nerves while scents aroused him. He felt it, smelt it, tasted every molecule on his tongue.
No, he didn't need it, but he loved it.
Like a fire in their veins, the hunger never truly stopped its burning, always there, just beneath the surface. One hour apart was easy. Two or three, well, they were bearable. Much longer and the sparks would flare anew.
They'd imagined, once the novelty wore off, that it would lessen - this need to come together, flesh to flesh. Instead the craving built, the lust grew stronger, and the love - love that demons aren't supposed to feel - that grew as well.
Each time they merged the bond grew even stronger and the flames inside burned ever that much brighter than before.
Sometimes Xander likened Spike to a wicked water sprite, his Sire spent so long stripped to the skin and soaking wet. Showers, baths and saunas curled his hair and gave his skin a burnished sheen. The suggestion of a hot tub in the spare room almost made him cream.
Lotions, potions, gels, oils and unguents galore, if they made it for the bath Spike tried it out. Not that Xander minded having a Sire with a water fetish, when a wet Spike was a happy Spike, and happy Spike was always, always horny.
Maybe he should suggest installing a pool...
