Xander woke from his pleasant dream unsurprisingly hard. He opened his eyes and startled when he found Spike on the bed beside him. "I didn't touch you," he promised. "Which was difficult," he continued as he shifted closer. "You smell delectable," he purred as he leant in and sniffed the brunet's neck.
"I-" he started and cut off as the blonde's nose pressed right against the base of his neck and he shivered. He blushed as he realised just this was making him hard. Hopefully, he could blame some of it on the morning wood he was sporting.
"Utterly delectable," he purred, voice rough with want.
"Um, Spike, you can't bite humans, remember?"
"I'm not thinking of biting you mate," he retorted, pulling back to grin wickedly at the brunet.
"You're not?" he replied, blinking.
He shook his head slowly. "Thinking of something else entirely," he stated, and held the brunet's hand against his hard cock.
"Okay, you're, um, oversharing," he babbled, blushing.
"Only if you're not interested," he retorted with a smirk. Xander opened his mouth. "I know you got harder when I got close," he stated. The brunet blushed harder. "Can't hide that sort of thing from my kind mate." He met the human's gaze squarely. "It's just occurred to me, that I haven't repaid you for putting me up." His companion swallowed. "Least I can do is help you out, right?"
"No that's-" he started and cut off when Spike tugged down his pants, and it was already too late.
The vampire's nostrils flared. "What do we have here?" he drawled, shifting down until he could see the source of that delectable smell. "Interesting," he purred as he spotted the liquid dripping from the brunet's hole. "Got a little souvenir from your hyena-demon, did you?" Xander averted his face with a blush. "Ever explored?"
The brunet's head snapped in his direction. "No!"
"Why not?" he retorted. "Just because you weren't born with it, means you can't enjoy it?"
"I wouldn't enjoy-" he cut off as Spike slid a finger into his hole and he moaned.
"Think we've found the way I can pay you back for being my host," he drawled as he slid another finger into the brunet.
"But-"
"Do you really want me to stop?"
"No," he admitted softly.
"Well then," he purred with a wicked grin. "Enjoy – and think about the consequences after."
"Better make it good," Xander retorted.
Spike's grin widened as he scissored his fingers, causing the brunet to cry out. "Don't worry, pet, I'll make sure of it."
