****** The Perfect Use of a Library ******
by theinsaneeraser
Summary
     Castiel and Sam retreat to the library for studying, Gabriel finds
     them anyways.
Notes
     They are between 16-17, well Cas and Sam are 16, Gabriel is 17.
Sam was enjoying the silence.
It wasn’t that he disliked his boyfriend, no Gabriel was fun to be around, and
got him out of his shell, but he did enjoy quiet times too; to study. Castiel
agreed with him, which was how they ended up at the local library, one Cas and
he would come too when they needed some time alone, from Gabriel. They enjoyed
this time alone together in silence, where they could work, breaking only to
smile at each other.
Yeah, so he had two boyfriends, and that they were brothers, and that they were
all together. If Dean ever knew about this – not that he had any time to spare
between screwing Lucifer or football – he’d flip his shit, be jalousie as hell,
but flip his shit; he was such a mother. Just the thought of it made Sam snort,
which drew Cas’ attention away from his book.
“Is everything alright Sam?” He asked and put his book down. Sam nodded and
flushed a little. “Does it have to do with Gabriel? You always blush when you
think of him.” Sam felt his cheeks heat up anymore and he opened his mouth to
protest, but Castiel gave him a knowing smile. “It’s alright Sam, I believe he
has… corrupted both of us, I believe that is the proper term for this.”
“Yeah, definitely.” Sam groaned quietly and leaned down in his seat. “But no, I
was thinking about De-ah!” Sam cried out softly before quickly clamping a hand
over his mouth, looking around to make sure no one had heard him. He then
looked under the table, and yup, sure enough Gabriel grinned up at him with a
mischievous smirk.
“You two thought you could run off and have a boring time without me?” He
grinned and Castiel frowned, crossing his arms. “Oh come on lil bro, you know I
can’t help myself.”
“Gabriel I don’t thi-” Castiel’s mouth slip open and Sam clamped a hand over
it, stifling a moan before biting down on his own palm as Gabriel slid his hand
in his pants, gripping him. “Gabriel!”
Sam leaned his head onto the table and moaned into his book as he jerked his
hips forward. He lifted his head as Castiel mewled next to him and bit down
hard on his bottom lip. Sam gasped when Gabriel undid his pants, tugging them
down and took him into his mouth. He wanted to kick at Gabriel, to tell him to
smart up but if he opened his mouth he’d moan loudly and the whole library
would know what they were doing, and he’d get kicked out.
Fuck.
He groaned when Gabriel bobbed his head, fast and sinful and oh god, Castiel
was gripping his arm, moaning into his neck as he too was attacked. He guessed
Gabriel must be jacking him off and just the thought of it was enough to turn
Sam on completely, make him forget why this was a bad idea. He swallowed hard
and ran his fingers through Cas’ hair, trying to calm him a little as he thrust
forward, moaning into his hand.
“S-Sam.” Castiel gasped and dug his nails in. “Sam I’m going to…” he whined and
bit down on Sam’s neck, drawing a startled cry from his throat, which he choked
back down. “Sam, I-I can’t, n-not here, nng.” Castiel whimpered softly and Sam
could feel Gabriel chuckle around his cock.
Sam quickly turned to the side and kissed Castiel, letting out a soft shout as
he came, allowing the kiss to stifle the sounds as Gabriel swallowed, licking
him clean. He continues to kiss Cas after Gabriel had finished, because he knew
Castiel was next. Castiel let out a startled cry – Gabriel must have taken him
into his mouth – and clung onto Dean for dear life.
Sam rubbed his back, running out of breath quickly, but unable and unwilling to
break the kiss. Castiel didn’t pull back either, just pressed closer before
mirroring Sam’s shout and bit down – a little hard – on his bottom lip. Sam
grunted and Castiel quickly licked at it, soothing it softly before pulling
back and panting.
Sam sucked in much needed air and slowly let go of his grip on Cas’ shirt as
Gabriel plopped into a seat next to him, grinning.
“That was fun, we should do that more often.” He smirked. “So, what are you
working on?”
Sam and Castiel both glared at him, panting and flushed. Oh no, they would
definitely not be doing that again. Sam quickly did up his jeans – which
Gabriel had left undone, and Castiel did the same before closing his eyes,
composing himself. Sam sighed and got back to work, keeping a close eye on
Gabriel, because who knew what else his bored boyfriend could get up too when
he was, well, bored.
