****** Of Aomine and his Angst ******
by TomKat
Summary
     Aomine has always thought of Kuroko when he's rutting, since
     presenting. This is a Problem.
     Or alternatively Aomine has a lot of kinks and Tetsu is the subject
     of all of his fantasies.
Notes
     I promised porn.
     Here is porn. Short porn, more imaginary scenarios than srs man on
     man but hey ho.
     It's also not really the 2nd fic in this timeline but w/e- wibbly
     wobble time-y wime-y
See the end of the work for more notes
Even during his very first rut, just after he had presented, Aomine had always
thought of Tetsu. His best friend (apart from Satsuki anyway), his basketball
partner- it made complete sense to him that they would be mates- they were
partners, they were meant to be. Tetsu couldn’t be anything but an omega- his
larger eyes, his way of looking up underneath his eyelashes, the way he would
go to small children and animals when surrounded… it all fit. Even when it
didn’t, because Tetsu was feisty and stubborn in his monotonous way and while
he lacked defined muscles he had no softness to speak of. It seemed like Aomine
should have figured out that Tetsu was not going to present as an omega, and
maybe subconsciously he had; but it still felt like a betrayal when he found
out from Midorima- even more so than when Tetsu quit the basketball team.
Tetsu still featured in his fantasies though. When he was on the roof, he had
Tetsu beside him. When he was playing basketball, Tetsu was aware of him,
waiting for the perfect moment to pass. And when he was horny… Tetsu was there,
his small hands running down his cock, the different skin tones only enhancing
the effect because he could see and feel the phantom player at all times. Tetsu
would start slowly, rubbing up and down with slick fingers, pausing to swirl
his thumb around the top at an agonisingly steady speed. If he was in a
torturous mood Tetsu would go hard and fast for a while, until Aomine was
panting and sweating and begging- it was supposed to be beneath an Alpha to beg
but Tetsu had always done strange things to him- and then he would stop. Aomine
would be left gasping as Tetsu looked down with a smile, tracing the cold hands
father away from the place that needed them most. The knot would be building
but Tetsu would put his finger over Aomine’s lips and tell him to “wait a
moment”. It would be a beautiful pain that made him ache with pleasure. Then
the moment would be over, and Tetsu, appeased, would use both hands to get
around the whole of his penis and finally, finally jerk him off properly. Tetsu
would end up covered in his come, all sticky and all belonging to Aomine.
Beautiful.
Then there were other times, when he forgot Tetsu wasn’t an omega. He would
have played with Tetsu’s arsehole enough so that it was all lubed up, licking
and thumbing and sticking his fingers inside. Tetsu would be sweating and
quivering, the adorable expression that wasn’t really an expression at all on
his face as he tried to ask Aomine to put it in without words. Teasingly, he
would oblige, pushing in as slowly as he dare, relishing the new look of both
pain and pleasure on Tetsu’s face. He would put his fingers; the ones that had
been in Tetsu’s arse into his partner’s mouth and have him suck them as he
thrusted. He would thrust at a snail’s pace at first, giving Tetsu time to
loosen up a little and for himself to enjoy the heat and tightness, before
giving over to his baser urges. His knot would fill Tetsu to the brim, and
Tetsu would hold his own hands to his stomach, rubbing the noticeable bulge of
Aomine’s penis as it thrusted. After the first time, once both of them had
come, they would change positions. Tetsu would sit facing Aomine and they would
move together, as Aomine couldn’t pull out until all the come was spent and his
knot had deflated. It could take hours. Hours of him and Tetsu, locked
together, coming and coming and coming.
Another thing Aomine loved thinking of Tetsu with a round belly. Ideally it
would be with their child, but Tetsu always looked so thin, it was arousing to
think of him with a huge, tight stomach. It had started when the team ate out
at a fast food outlet, and Akashi had made Tetsu eat the entire meal, instead
of just a milkshake. The team was surprised that by the end there was a
noticeable bulge around his stomach. It seemed to be big enough to rest your
arms on, but maybe that was just his perception of it. Tetsu had unsurprisingly
complained of a stomach ache, so Aomine decided to massage it. The feeling of
the taunt skin over a tight frame had been his downfall, and so began the
hopeless obsession of having Tetsu inflated, filled with something, be it food
or babies. Then again, if he could even fit his dick inside Tetsu, and Tetsu
didn’t pass out or something stupid, it was a common theme in the Alpha/Beta
porn he had stumbled across for the Beta to be filled with the Alpha’s come.
Tetsu wouldn’t get pregnant, but the large amount of Aomine’s cum could make it
look like it. Maybe it would take a few tries- he could make Tetsu wear a butt-
plug or something.
Then again, he had newer fantasies that seemed a lot more workable. After the
game with Kagami- Tetsu’s new light, how laughable, he wasn’t even a proper
Alpha- he began to imagine how good it would feel to shack up with both of
them. Not properly, he wouldn’t be able to fit his dick inside either of them
without a lot of work, but he could have them suck him. Kagami would probably
do it just as he played basketball, single-mindedly, simply, aggressively;
while Tetsu would do the teasing, licks down by his balls and over the top.
Deep-throating Kagami to get him to shut up and teach him a lesson about
respecting his betters while Tetsu nipped gently and massaged his balls with
his tongue would feel amazing. He would make Kagami swallow, choke him slightly
with the thickness of the come, and then Kuroko could lick him clean. He would
then move them slightly- the basketball changing room sounded like a
particularly satisfying theatre for a show. He would make them fuck each other
for him, Kagami taking it like an Omega while Tetsu fucked him hard, biting and
scratching each other the way they hit each other around outside of games (and
in games, according to Midorima). It would be his personal porn show, he could
direct them with commands like “harder” or “faster” or “bite” and allow them to
come only when he says so. It’s damn arousing, imagining dominance over two
people.
On rare occasions he fantasises about making Tetsu into the omega he was meant
to be- injecting him with the hormones and then fucking him every single day,
so that his hole slowly began to change. These fantasies have a rape-y sort of
feel to them though, he’s really not sure if Tetsu would like it, or even
consent, though that doesn't stop him in his dreams. Depite this, he wants
Tetsu to be happy, however much of a jerk he may act towards him.
It’s not really a surprise that he calls out for “Tetsu!” during sex with any
of the nameless, faceless omegas in heat. He doesn’t try very hard to stop
imagining that Tetsu is right behind him, just out of sight. It doesn’t stop
the times he wakes up hard, chasing after a dream. It doesn’t stop the reality
that he gave up on the one thing he truly wanted, more than a proper rival for
basketball, and it doesn’t stop him feeling like a phoney once the boner has
gone down.
End Notes
     Now I need to actually work at the sort of plotty elements of this
     AU.
     and also longer sex scenes but that's another story.
     If anyone thinks this is going to be awesomely happy, I'm going to
     disillusion you now. It's going to be a series focused on the
     craptastic world that is the A/B/O verse for... pretty much everyone
     who isn't an alpha- though the alphas have their own angst anyways.
     Oops.
     But I'll try and make it as happy as possible?
