****** Call His Name Instead ******
by MicroFox25
Summary
     Sirius is in the library when Harry offers him something that he
     simply can't say no to.
Notes
     I had this idea the other day, where someone wants their partner to
     call a different name so they'll be happy. It's kind of a reverse
     'calling a different name' trope. I don't know.
See the end of the work for more notes
“Sirius?” The man looked up from his book, seeing Harry in the doorway of the
library. Putting a marker in the book, Sirius put it on the stand then motioned
for Harry to step forward. Harry looked so small for some reason, looking more
vulnerable than Sirius had ever seen him. Harry turned around closing and
locking the door. He was holding himself, shoulders pulled in, not looking at
Sirius as he walked forward. Harry didn’t sit, but rather stood almost over
Sirius, gaze locked on the wall behind Sirius’ head. “Is something wrong?”
“No.” He tumbled out shortly, taking a breath. Sirius understood. He was
working up the nerve to talk about something. Was he going to want to talk
about something embarrassing? Maybe sex? Sure Harry was fifteen, but he was
living with the Dursleys so he didn’t expect them to teach him. He knew for
sure that they didn’t teach these things.
“Then what-”
“I know that you see my father when you look at me.” Harry almost yelled,
squeezing his eyes closed. Sirius wanted to argue, to assure Harry that he
definitely saw Harry and not James, but he didn’t have any words. “You had
feelings for him, didn’t you?” That snapped Sirius out of the daze the prior
sentence had set him in. Sirius stood, making Harry jerk back in fear. Sirius
winced. He didn't mean to stand so fast.
“Harry, my relationship with your father-”
“So you did. You loved him.”
“Harry…”
“I bet you wish he was here right now?”
“That’s obvious. He was my best friend.” Harry’s eyes had finally set on
Sirius’, his gaze intense.
“What if…” Harry cut himself off, uncertainty flashing momentarily behind his
eyes. He licked his lips, Sirius’ eyes following the movement.  “What if you
could have him again?”
“What are you saying, Harry?”
“Did you…” He swallowed thickly. “Did you ever want to sleep with him?” All of
the blood left Sirius’ face at what he realized Harry was suggesting.
“Harry, that’s-”
“You could. I’ll close my eyes or you can cover them and won’t say anything and
it’ll be just like doing it with him.” Harry explained, almost excited, pulling
out a bandana from his pocket, offering it. “You could even say his name to
make it seem more real. I won’t be upset.”
“Stop it!” Sirius screamed. Harry recoiled, eyes widening with fear and… was
that disappointment? Sadness?
Rejection.
Harry was feeling rejected. After all that talk about being there for his
godson, all he ended up doing was treating him like everyone else had. He never
wanted to hurt Harry. Sirius loved Harry more than anything. Sure the thoughts
weren’t entirely innocent, but this couldn’t happen. Harry was far too young,
not to mention that Harry was offering himself to be a replacement for James.
“Harry, it’s not right.”
“Why not? It’s not like you’re forcing me. I’m doing this on my own.” Harry
turned back to Sirius, looking at him, pleading with his eyes. “It’ll be just
once. If it’s no good, we never have to do it again. I’ll never tell anyone. No
one will know but you and me.” The way Harry was looking at Sirius was making
him weak. Complete trust and adoration. Why was Harry suddenly bringing these
things up? He was going to regret this. He was going to regret the whole night
for the rest of his life. Hopefully, it would be a short one.
“Only…” He took a breath, unable to look away from the sharp green eyes. “Only
once.” A smile cracked Harry’s face, brightening the whole room. Oh, god, he’s
going to regret this.
===============================================================================
There Harry was, sitting on Sirius’ bed, waiting patiently to be treated like a
sex toy. Was it too late for Sirius to back out of this? Sirius was standing in
front of him, looking down at his innocent face. “Take off your shirt, Harry.”
Obedient as anyone, Harry pulled off his shirt, revealing an expanse of milky
caramel colored skin. Harry decided to get ahead of Sirius, pulling off the
rest of his clothes. Now he was sitting on Sirius’ bed, completely naked.
Sirius inched forward, standing in front of Harry. Harry, who offered the
bandana, already folded in a blindfold. The older man sighed, wrapping the
cloth around Harry’s head, tying it loosely in the back.
“You can make it tighter. It feels like it’s going to fall off.” Holding back a
groan, Sirius tightened it, careful of the boy’s hair in the knot.
“Lay back.” Harry obeyed, leaning until he back touched the bed. “Have you ever
touched yourself?” Hesitant, Harry nodded. “Where?” Using his hand and no
words, Harry moved his hand to his prick. “Have you ever touched your hole?”
Sirius watched a blush darken Harry’s skin. He shook his head as Sirius moved
him around, propping his legs on the bed to expose him. When his finger slid
over the opening, Harry jumped. “Do you want to stop?” Harry shook his head
quickly. “This is what you’re offering me.” When Sirius was met with silence,
he sighed. “You’re allowed to talk.”
“I- I know. It just shocked me.”
“Get used to it.” Sirius felt his throat burn as he tried to swallow, but his
mouth was far too dry for it to work. “James.” It didn’t even taste right
coming past his lips. Sirius reached into his nightstand, pulling out the lube
and, as a second thought he also pulled out a peculiar box. He had gotten it as
a gag gift from James a long time ago, but never opened it. It was almost
ironic that he was using on Harry who was pretending to be his father. “I’m
going to use this toy on you first to get you used to it.”
“Toy?”
“It’s an interesting thing. It vibrates and moves on its own.” The sound that
came out of Harry could only be described as a squeak. “Do you want to stop?”
“No. I’ve just never…”
“Well, I wouldn’t think so. Do you have any problem with being tied up?” Harry
shook his head, so Sirius went to his closet, pulling out as many long and thin
things as he could find, settling on the tie to a bathrobe, a belt, and four
ties. He used the bathrobe tie on Harry’s arms, tying him to the frame of the
bed. He tied two ties together, each going to Harry’s thighs, keeping his legs
up and apart. Part of him was hoping that since he couldn’t talk Harry out of
it, he would scare Harry out of it. So far, that wasn’t working.
Opening the lube, he wet two fingers, touching Harry’s leg before lowering his
other hand, touching his hole again. “Relax your body.” Harry grew pliant,
relaxing his whole body. When Sirius pushed his finger in, Harry tensed before
quickly relaxing again. Soon, Sirius was able to thrust his finger into Harry
easily adding a second finger. When Sirius pushed a certain spot, Harry arched
up, calling out. Sirius pulled away entirely, picking up the box. It was rather
small, only about the length of his hand and the thickness of two of his
fingers. Harry should be able to take it easy.
When he touched it, his hand tingled slightly and Sirius recognized what it
felt like. The toy was matching his magic signature. Sirius smiled, lubing the
toy and sliding it into Harry carefully.
“Is that… the toy?”
“Yes.” Harry nodded, almost to himself, body relaxed so Sirius slid it to the
bottom. He looked at the box as he picked up his wand. “Usus ludere. ” He
called and the toy began to move in and out of Harry, making him exclaim.
Sirius watched the toy disappear into Harry before pulling back out almost all
of the way before plunging in again. “Want to see what else it does?” Harry
couldn’t respond, only able to make the small noises of pleasure. “I’m going to
take that as a yes. Strenuus irritationibus corruptae.” Sirius watched as Harry
tensed, body arching into the air as he moaned loudly. “Hmm. That was an
interesting response. Altiorem.” With that, Harry nearly screamed, so Sirius
quickly made sure that the room was silenced. Only his toes and head were
touching the bed. If Sirius really concentrated, he could almost hear the
vibrations when the toy moved out of him. Harry gasped something so Sirius
leaned over him. “What was that?”
“I’m gonna-” Sirius increased the strength one more time, Harry’s voice became
hoarse and his thighs were shaking with the strength of it and this was the
hottest display that Sirius had ever seen. It almost hurt he was so hard.
Harry’s body twitched as he came in long spurts, a feral sounding moan ripping
out of Harry’s chest. Harry’s body was still twitching when Sirius pulled the
toy out and turned it off. Sirius stripped himself of clothes, climbing on the
bed, watching Harry tense. “Give… give me a minute. Please.” Sirius didn’t
respond but started to rub his hands down Harry’s thighs.
Sirius moved to where Harry was in his lap and leaned over him. Licking a path
from Harry’s sternum to his ear, Sirius shifted his hips so his dick was
sliding against Harry’s. He could see it twitching back to life. Harry stifled
a cry as his hips jerked up. “Do you want to stop?” Harry said nothing, jerking
his hips against Sirius’. “Do you, James? This is what you wanted, wasn’t it?
To be treated like an adult? Like your father? Do you want to continue?”
“Please. Sirius please.”
“Please, what?”
“F- fuck me.” Sirius’ dick twitched against Harry’s and he scrambled for the
lube, coating his prick angling it towards Harry’s hole.
“Are you ready?”
“Yes. Please!” Sirius couldn’t stop himself, shoving his hips forward. Harry
tensed as Sirius looked down. He was almost all the way inside of Harry.
“Sirius. I- I can’t take it. Please move.” Sirius wasn’t going to be one to
deny Harry, so he grabbed the smaller hips, thrusting in all the way before
pulling out and taking no time to push his hips back in.
Using his hips as leverage, Sirius began to thrust into Harry, listening to the
string of moans that were ripping out of the body under him. “Sirius. Please
untie me.”
“Right.” He rolled his hips as he reached up and struggled with the robe tie.
His hands were shaking. When was the last time sex made him shake? Never, if he
actually thought about it. What was this kid doing to him? Eventually, he just
gave up, grabbing his wand and vanishing the ties. He wouldn’t miss them.
God, he must be getting old. He wasn’t going to last very long. Sirius grabbed
Harry’s prick, stroking it in time with his thrusts. Harry let out a squeak as
Sirius touched him, rolling his hips into the motion. “S- say it, Sirius.”
“J… Ja...” He tried. He really tried. “I can’t,” Sirius admitted. He will admit
that the pleasure was getting to his head. “Fuck, Harry. I can’t.” He reached
up and tore the blindfold off, catching Harry’s hair no doubt. Neither seemed
to care as Harry’s crystalline green eyes blinked up at Sirius.
Sirius jerked his hips forward, pleased with watching Harry’s eyes rolled from
the pleasure of it. The fact that he was doing this to Harry, making him
respond like this, it was more pleasing than actually being inside of the boy.
“Sirius!” Harry choked out.
“Harry, I'm-” He could only manage another hard thrust and he was emptying
himself into the willing body. His vision went white and he gritted his teeth
feeling Harry tighten around him, milking him to completion.
===============================================================================
I loved him like a brother,” Sirius explained. He was sitting on the bed, the
blanket covering his bits, while Harry was wrapped around him, just as naked.
“That’s all he was to me. A brother. Like Ron is to you.”
“So you didn’t…” Harry looked down, his cheeks coloring with a blush.
“No. But I can understand where you thought that. My question, Harry, is why
you were so desperate to do this, going as far as to tell me to pretend you
were James.”
“A better question is why couldn’t you? Why did you have to see me?” Sirius ran
a hand through Harry’s unruly hair. He looked down at the boy.
“C’mere.” Harry moved, straddling Sirius. He cupped Harry’s face in his hands.
It wasn’t uncomfortable to have Harry’s naked flesh against his own. “I love
you, Harry.” He pressed his forehead to Harry’s. “More than anything.”
“I…” Sirius understood why Harry was hesitant. Growing up with a lack of
affection made emotions hard to deal with. He knew from experience. Sirius felt
Harry’s cold fingers slide across his face and tangle into his hair. Sirius was
pulled into a kiss, shocking him into pulling away. Dejection passed through
Harry’s eyes again, so Sirius pulled him back in, kissing him with the skill
he’d adapted over time. Sirius thought that all of the kissings he’d done in
the past was to prepare him for this moment. “I love you, Sirius.”
