by The_Heart_of_an_Angel
Summary
     Dean and Castiel go to the same high school. Dean is a cool Senior,
     and Cas is a dorky freshman. Castiel has had a crush on Dean since
     the beginning of the year, and things get a little heated when Dean
     is tutoring Cas in Global History at his house.
     Basically teasing and then smut. <3
Notes
See the end of the work for notes
Cas was twiddling his thumbs, sitting on the couch in his living room. His
heart was thumping loudly in his chest, and he couldn't believe what was about
to happen. Dean Winchester was coming over to his house... to tutor him.
Castiel hated Global History. It was boring, and he had no interest in it at
all. He was more of an English kind of guy. However, when said hot senior
offered to help him and his slipping grades, he immediately thanked God for his
total disinterest in the subject. 
He had his binder open on the old wood coffee table, a jam jar full of pencils
stood beside it, just in case they were needed. He'd taken out his homework
assignment for the night and had it neatly set down on his binder, ready to be
worked on. He could not wait until Dean was sitting next to him on his soft
couch. Their knees brushing, smiles passed between them as Cas finally
understood the first question. All thanks to Dean. He could see them now,
sitting so close that their noses are nearly brushing...
He squealed and jumped up as the doorbell rang. 
"Crap! He's here!" Cas ran to the mirror that hung near the front door. He
pushed his glasses up on the bridge of his nose, straightened out his dark
purple sweater, and the collared shirt underneath. He quickly made sure nothing
was in his teeth, and that his breath smelled decent before he opened the door
coolly. Dean stood on the front porch, a giant compared to little Castiel. "Hi,
Dean!" Cas said cheerfully, his heart fluttered.
"Hey there, Cas." Dean said in the smooth, deep voice that made Cas shiver a
little. The freshman let the older boy inside and led him to the living room. 
"Uh, we can sit here!" He plopped down on the couch, and Dean followed. The
older boy leaned back with his hands in his jean pockets. 
"Comfy." He commented simply. The house was kind of dark, with dark brown
furniture, and tan walls, but the light streaming in through the bay windows
made it seem brighter. Dean noticed all the little details of Cas' home: the
family photographs and paintings on the wall, antique lamps and the record
player in the corner of the room. Cas noticed that he saw the record player,
and stood, moving over to it. 
"Wanna listen to some music while we work?" Cas asked. Dean nodded, so Cas put
on a Glenda Rae record. He made sure to bend over, sticking his little butt in
the air, while trying to find the record. The music started to play softly, and
Cas sat down close to Dean. "So, wanna start with my homework?"
Dean nodded. "You got any questions you found particularly hard?" Cas nodded,
blinking his eyelashes at him. 
"Yeah," He picked up a pencil, and his homework. "Number five is confusing."
Dean leaned over Cas' shoulder and read the question.
"Which of these belief systems is linked to the Eighth Fold Path, the Four
Noble Truths, and Siddhartha Gautama?" Dean said aloud. He bit his lip and
thought for a moment. "Well, what part of that question do you know? Do you
know who Siddhartha is?" Castiel nodded. 
"He's the Buddha."
"So, it's linked to...?"
"Buddhism?" Cas pushed his glasses up on his nose. He made sure his eyes looked
largely, and more puppy-dog-like than normal, and he pouted his lips. 
"Right," Dean chuckled. "See? You know this! You're super smart." 
They worked on a few more questions, until Dean was leaning on his right arm,
which was behind Castiel, and leaning over the younger boy's shoulder. Cas
smiled and laughed when they finished. 
"Thank you for your help, Dean!" He gave the boy a hug. Dean smiled and hugged
him back. 
"No problem, man, you're actually good at this stuff. It just seems like you
have trouble concentrating sometimes." Dean pulled away. Cas looked up at Dean
with big eyes and giggled. 
"Yeah, I do get distracted," He paused, and put a hand on Dean's thigh. "Mostly
by you, though," He whispered in Dean's ear. Dean's eyes widened and he pulled
away from Cas. 
"C-Cas, what are you-?" Cas cut him off by climbing on his lap, and sitting on
the older boy's crotch, which was half-hard. 
"Come on, Dean. Like you never notice me staring at you in study hall," Cas
breathed, wrapping his arms around Dean's neck. "You're just... so hot." Cas
may have seemed like he knew what he was doing- part of him did- but most of
him was freaking out because he was acting... crazy. "I couldn't take not being
able to touch you anymore, every time I see you I just imagine what it's like
to..." He slid his hands down Dean's chest. The older was breathing heavily,
and staring at Cas with an intense heat in his eyes. "You make me so hard,
Dean. Just by being yourself. One time, you were doing homework, and you
stopped," He bit Dean's earlobe softly. "And you stretched and I could see that
fine line of hair that runs down your stomach. Your abs..." Dean shivered, and
groaned. 
"Cas, please-" Cas kissed Dean hotly. He'd never kissed anyone before, so it
was a bit sloppy. Dean lifted his hand to Cas' jaw, and slowed him down. He
showed him how to really kiss: slowly and deeply, cautiously sliding his tongue
into the younger's mouth. Cas whined and gripped Dean's short hair. He pulled
away, breathing harshly. 
"Dean, please, I need you." He begged. Dean shook his head. 
"You're too young, you've never... have you?" Cas shook his head, biting his
lip.
"I want to with you, please," Cas ground his ass into Dean's now fully hard
cock, which was tenting the front of his jeans. "Fuck me, Dean."  This made
Dean growl, and he flipped them over on the couch. Cas looked a little scared
as Dean was now fully on top of him, knees on either side of him. 
"If you really want this, Cas, we'll go slow. Do you have protection and lube?"
Cas nodded to his question, pointing at his backpack on the floor.
"I stole some from my dad..." 
"Fuck, you planned this," Dean flushed with want, reaching down and grabbing a
condom, and a small bottle from the front pocket of the backpack. He set them
on the coffee table, and went back to paying attention to Cas. The little dark-
haired boy was trembling, his blue eyes blown wide. "Don't be scared, Cas, I
promise I won't hurt you." He kissed Cas again, putting his large hands through
the boy's soft hair. 
They started slow, just like Dean said. Cas put his hands on either side of
Dean's face, feeling his light stubble. Dean had his right hand move from Cas'
hair, down his neck, and to his chest. He slipped it beneath Cas' shirt,
brushing over his nipples. Cas gasped, and his face flushed red. Dean hummed in
delight and did it again, this time stopping to pinch them a little. 
"You've never had anyone play with your nipples, and yet you're so sensitive,
baby..." Dean said in that low voice. Cas whined and moved his hips up
involuntarily. Dean chuckled and lifted Cas' shirt, pulling it over his head
and letting it fall on the ground. He kissed down Cas' long, pale neck and to
his hairless chest. He was so skinny, Dean could see his ribs moving beneath
his skin. He sat on his knees over Cas' legs and slowly moved his hands down
the boy's torso. He leaned down and sucked one nipple into his mouth. Cas let
out a loud moan. 
"Fuck, Dean! Please!" He closed his eyes and flushed a deep red. He couldn't
believe this was actually happening. Dean Winchester was sucking on his
nipple...
Dean canted his hips into Cas' knees. He was achingly hard, and he could tell
that Cas was too. He let Cas' chest go and breathed out. Cas looked beautiful;
shirtless, wanton and blushing. 
"Dean, this is going too slow, please, please..." Cas slid his hands down his
own torso, and squeezed his erection through his pants. "Please, Dean, I need
it." He whined. Dean almost fell off the couch, he pulled off his shirt so
fast. 
After his shirt was disposed of, he unbuttoned and unzipped his own pants. Cas'
pants were practically torn off of him, leaving him in his boxer briefs only,
hard-on obvious through them. 
"God, you're so hot, Cas-baby..." Dean leaned down and mouthed Cas' erection
through his underwear, soaking it in his saliva. 
"Ohhhh... Dean, please!" Cas pulled his head up off of him, and slid his
underwear down. "Come on, Dean, fuck me with your big cock!" Cas demanded. Dean
chuckled. 
"Not so fast, baby, first we gotta open you up, or it'll hurt." Dean picked the
lube up off the table and clicked it open. Once his fingers were generously
covered with lube, Dean slid one around Castiel's entrance. Cas mewled, and
Dean moaned. He slowly pushed the first finger inside, and Cas squirmed. Dean
gently moved the digit around, back and forth, opening Cas' tight hole. Cas
spread his legs wide, one hung off the edge of the couch.
"Dean..." Cas' eyes were tearing up, it burned, and felt weird. He didn't want
to stop, he just wanted it to feel good. 
"It's 'kay, just a little more, tell me if it hurts too much," He added a
second finger, felt around for that little bundle of nerves that would make it
feel really good for Cas. When Cas nearly screamed and thrust his hips up, eyes
wide, Dean knew he'd found it. His arousal throbbed at the look of little Cas. 
"Come on, Dean, I can't last much longer. Fuck me! Come on! I need it, I need
you!" Cas begged, breathlessly. Dean leaned back and pulled his pants and
boxers down, letting his cock free. It felt better not being trapped inside his
clothes. One hand kept moving, opening Cas, as the other reached for the condom
on the table. Once it was unwrapped and on Dean's cock, he leaned forward over
Cas.
The younger boy had been expecting Dean to just thrust right in, but he hadn't.
Dean was kissing him, slowly and softly. He pulled his lips away just a bit and
Dean whispered. 
"It's okay, it's going to feel so good, Cas."
He angled his cock to Cas' opening and slowly slid in. The noise that was
forced from Cas' throat was loud, and breathy. Dean watched Cas' face to make
sure he was okay, then slid in further. He stopped again, almost completely
sheathed it Cas. He really hoped he wasn't hurting the other boy, and a twinge
of guilt pinned his chest. Cas felt the burning pain as Dean pushed into him,
but he didn't say anything. He trusted Dean to make him feel good.
"Oh.... God, Dean. Move!" Cas exclaimed. He pushed his hips back, pulling Dean
all the way in. Dean gasped at the pressure around his dick. 
He had both hands on either side of Cas' head, and began thrusting his hips
gently, sliding slightly in and out of Cas. The younger boy was moaning and
letting little whines out from the back of his throat. Pre-cum dripped from his
hot, throbbing arousal. 
"Fuck, Cas. You're so beautiful. So fucking good," Dean could feel himself
going over the edge, and he sped up. Cas' legs wrapped around Dean's waist so
he could thrust along with Dean. Tears were starting to form in his eyes that
were squeezing tightly shut. He'd never had sex before, and though it felt
amazing, it also hurt, and he could feel his ass throbbing in pain. 
"Oh! Dean, harder! I'm gonna come!" Cas mewled. Dean strengthened his thrusts,
face turning red. Cas' eyes snapped open and his mouth gaped open as he finally
came, spurting semen over Dean's torso, and his own chest. Dean had yet to
finish, so he keep thrusting. 
"Cas, talk to me." The younger boy raised an eyebrow. His head was cloudy from
his release, but he did as Dean asked. 
"Dean, you're so hot. Fuck, your cock is huge. It can barely fit inside my
little hole. I want you to come over every day so you can tutor me. Fuck me,
harder. Come, Dean. I wanna see your face when you release." Cas breathed in
his ear. 
Dean came hard. He fell on top of Cas, breathing hard. 
"Damn, Cas, for a virgin you have a really dirty mouth," They both laughed a
little, and Dean pulled out before he softened. He sat up on his knees and tied
up the condom. It was thrown into the trash, and covered up by toilet paper. He
turned back to see tat Cas' eyes were wet and he was sniffling a little. He
hadn't even noticed he started crying while they were...
"Cas. you okay, baby? I'm sorry that it hurt, come here." 
He pulled Cas into a hug, kissing his wet cheeks and they laid down on the
couch, snuggling. 
"You know, Cas. I could come back over everyday."
"Really?" Cas' heart beat jumped.
"We don't have to do that every time. Some time, we could just, hang out. Kiss
and stuff. We have to be adults about it, though. If we're gonna have a
relation-"
"Are you saying you wanna date me?" Cas asked quietly. He snuggled his face
closer into Dean's chest. 
"Yeah, I mean, I thought that's why we did that just now." He pressed a kiss
into Cas' hair. 
"Yeah, I suppose so. I would like to date you, Dean," 
"Okay... Boyfriend," He chuckled. Cas closed his eyes, he couldn't stop
smiling.
Dean was Cas' boyfriend.
