The Boy Next Door: Lessons Learned

Xander growled as he paced the length of the basement. He was growing increasingly more frustrated as the study session went on.

"I'm just not getting it, Spike," he growled. "I'm too stupid to figure it out, alright. We should just forget about it and move on to something else. I don't know why I even thought I could do this in the first place. Actually, I do. It was Willow, talking about how sexy accents were and the girls would all go crazy over a boy that could speak French. Fat load of good it does me."

Spike snorted from his seat on the battered, lumpy couch. "Doesn't matter now, does it? You have to get it, Xander. You have to pass this test or you'll fail French. That's not an option, remember? You can do this, I know it."

Xander snorted his disbelief, staring at the blond boy from across the dank room. "I just can't get the hang of conjugating, alright? Let's just say I'm a hopeless cause and move on."

Spike stood up and breeched the distance in one fluid movement. He pressed in close to the shocked boy, their noses barely brushing as crystal blue eyes blazed with barely restrained fury and passion.

"I never want to hear you say those words again," Spike growled. "Ever. Do you understand me?"

Xander nodded softly, his nose bumping Spike's as he did. They stood like that for several minutes, frozen and staring at each other.

Finally, Spike pulled away, stalking back toward the couch where he had left his duster. Pulling the jacket up, the older boy turned toward the frozen teen before commanding, "Strip."

"What?" Xander nearly shrieked in fear.

Spike smirked evilly as he began to dig through his pockets. "It seems you need some extra incentive to learn your conjugation. I'll see to it you learn the lot by the end of the afternoon."

The sable haired boy laughed at that. That was, without a doubt, the craziest thing he'd heard all week.

But Spike wasn't laughing. He just stood and stared, his face unreadable.

Xander quickly stripped, dropping his clothes onto the floor as he stole glances toward the door that lead to the kitchen upstairs. He just hoped his mom wouldn't choose that moment to come down stairs to see if they wanted marshmallow treats or Kool-aid or something.

Once he was completely naked, Xander stood, facing his tutor, waiting silently for his next command.

Spike nodded toward the couch, waiting patiently until Xander went to sit down.

"No," Spike whispered, stopping the boy before he could fully sit. "On your knees."

Xander knelt on the rough, lumpy cushions, resting his hands on the back of the couch, digging his fingers into the ratty fabric. He turned to look at the older boy, unsure what was coming next.

Spike smiled at him, as if he was trying to reassure him, but there was lust and power reflecting on his face that made him terrifying. Reaching forward, petting Xander's lower back before trailing his fingers over the soft curve of the boy's ass. Xander gasped and shivered as gentle fingertips ran lightly over his goose-pimpled flesh.

Seemingly satisfied, Spike cleared his throat, capturing the boy's attention as he held a shiny toy between his thumb and forefinger.

"W-w-what's that?" Xander stuttered.

"They're called anal beads," Spike explained matter of factly. "Ready?"

"Ready for what?" Xander asked frantically. "What are you going to...those don't go..?"
The boy's head nodded down toward his sumptuous backside.

Spike barked out a harsh laugh before asking, "Why do you think they call them anal beads? Now, here we go."

Xander shook himself lightly, closing his eyes tightly before sighing heavily, waiting for what was next. He heard the soft 'snick' of a lid being opened before Spike moved to stand behind him.

"What is the verb 'to take'?"

"Emporter," Xander dutifully replied. He gasped loudly as he felt a cold slickness slipping between his cheeks and then a soft, persistent pressure until the first and smallest bead entered his body.

"Now. Conjugate it."

Xander took a deep breath, trying his best of make his brain work. "J'emporte."

"Very good," Spike praised, slipping another bead inside. "Next."

"Tu emportes." Another bead slipped in. "Il emporte." Another. Xander was trembling and fighting to keep from leaning forward to rub his aching erection against the scratchy cushions. His brain fought to remember what came next. "Nous emportez?"

The pleasure he'd become used to from the slick slide of the beads was replaced by a swift, sharp pain as Spike's hand came crashing down on the over sensitized flesh so close to where the beads entered his body. Spike leaned in close, the brush of his clothes whispering against Xander's naked skin making the boy shudder and keen.

"Want to try again?"

Xander racked his brain, forcing himself to come up with an answer. "Nous emportons."

"Very good," Spike purred, forcing the last bead inside the panting boy.

Xander continued to conjugate the various verbs as Spike instructed him, moaning as the string of beads was pulled in and out of him, flooding his body with waves of pleasure when he was correct and gasping in pain as he was spanked if he was wrong. They went through all the verbs required for the test twice, with Xander hardly missing any near the end.

They were nearly finished, with all the beads deep within the younger boy's body, when Spike leaned in, his front pressed tightly against Xander naked back.

"Knew you could do it, pet," he practically purred as he rocked his hips forward against Xander's sensitive skin. "Liked that, did you?"

Xander nodded frantically, his sable hair flying wildly around him.

"Noticed you were even enjoying the spanking at end there, weren't you, love?"

A flush spread up Xander's neck and face, coloring and warming him through. Slowly, he nodded softly, shy and embarrassed. "Why?" he asked, nearly too quietly to hear. "Why would I like that?"

Soft lips pressed between his shoulder blades, making Xander shiver all the more. "You see, pet, there's a very thin line between pain and pleasure. Sometimes, you can blur that line until even the pain can make you come."

Xander gasped loudly as Spike pulled at the beads inside him, pulling on them roughly, wrenching them from his body one by one. Arching his back, Xander cried out, coming hard against the rough fabric of the couch. He tried to catch his breath as Spike gently stroked him, running his warm hands over the trembling boy.

Xander slumped against the couch, Spike stood over him smiling as they heard a voice calling to them from upstairs.

"Xander?" Mrs. Harris called through the closed door. "Are you alright down there? I thought I heard someone yelling."

"I'm fine, Mom," Xander called back. "I just tripped."

"Alright," she called back. Xander waited to continue breathing until he heard her footsteps trailing away from the door and across the kitchen floor.

"Well, good luck on the test tomorrow, pet," Spike called as he walked into the small bathroom to clean his toy before slipping them away once again. "I'll see you tomorrow after class?"

Xander nodded, suddenly embarrassed by his nudity. He scrambled for his clothes and turned to the other boy as he pulled his jeans up, buttoning them quickly.

"Yeah, Spike. In the library, as soon as I'm done with classes."

The blond boy stalked toward him, sleek and fluid, stopping before the gaping boy. He leaned in, kissing the boy, softly at first, then more forcefully before finally pulling away.

"Sleep tight, pet."

Spike practically bounced across the lawn toward his home. He pulled the door wide, pleased at the delicious smell wafting toward him. He quickly went in search of his Da, needing to see the man as soon as possible.

Rushing into the kitchen, he smiled as his father stirred the heavenly smelling food on the stove.

"Hey, Da," Spike greeted as he rushed forward to be surrounded by the older man's arms. Ethan held him tightly before pressing a kiss into his son's blond locks.

"How did the French lesson go?" Ethan asked.

"Quite well," Spike answered, a wicked smirk spreading out over his face. "The boy'll be fluent in no time."

The elder Englishman laughed loudly, clapping his son hard on the shoulder. "He will be if he's half the student you were."

"Vous étiez un enseignant brilliant, Da," Spike purred.

"Et vous un tel étudiant dispose."

Tbc...
