****** Sensual Punishment ******

Summary
     Part of you feels like you should have expected this. Even before he
     presented, Ritsu would always get upset when ever you came home with
     someone else's scent on you. He would huff and pout and insist on
     scootching closer when ever you two ate dinner and before he left the
     next day he would wake you up just to scent mark you. You always went
     with it. It was kind of cute.
     Then he presented as an alpha

Aah..hah..



Your voice comes out hoarse and scratchy from practically screaming just
moments ago. He was being rough again, pounding into your over sensitive cavity
despite your whines and quiet please for him to slow down. you knew it was
pointless, that he wouldn't ease up.  Not until he’s claimed you inside and
out.  One well placed thrust causes you to arch as the electric shock of pain
and pleasure rips through you and the renewed mixture of slick and cum dribble
down your legs. Your head falls back down to the pillow beneath you and you can
faintly feel the wet coolness on your cheek. Ah..you were drooling.

Ritsu would always get upset when ever you came home with someone else's scent

mark you. You always went with it. It was kind of cute.
 
Then he presented as an alpha
 
At first everything still seemed the same. he was still driven, still the same
Ritsu from before aside from the now strong  scent of spice and something soft
that wafted off of him, but soon you began to notice how angry he would get
whenever you came home not smelling like yourself. You tried to assure him that
the smells were just the result of working out with your club members but he
would only get even more upset, complaining about their scent being all over
you. He would stormed off to his room after that leaving you  at a lost. You
never seen him so angry before but when you asked your father about it he just
attributed it to hormones and assured you that things would be fine.
 
Things weren't fine. You would realize this one night when you came home
wrapped up in a borrowed jacket from Reigen.
 
 The weather was changing and you had neglected to take a coat so Maser Reigen
had gave you his ' Bring it back tomorrow!'. You thanked him before you left in
a rush. Ritsu didn't seem well that morning and  wanted to hurry home in case
he needed anything. You announce your arrival and close the door behind you,
but before you could even take your shoes off he was there, his form rigid and
his face flushed and  his scent-  your nose practically stung from how strong
his scent was. He says your name with a darkness that made your knees weak and
before you could even question him he was on you, pinning you to the front door
and tearing at the offending garment.
You lost your virginity that night. and you had to make up an excuse for why
Reigen's jacket was in shreds.
Afterwards he seemed to calm down as he held onto you, holding you and hugging
you and  begging for your forgiveness. He had been hot and bothered that entire
day and when you came home with Reigen's scent mixed with the sweetness of
yours he just lost it. You forgave of course. How could you not? He's your
brother and you would do anything for him. Even if you had trouble walking the
next day. It was just the one time..right?
 
One time turned into two and two into three which lead to now. You don't know
what triggered it this time. Perhaps the unexpected touch from Tsubomi who also
presented as an alpha. She approached you after classes commenting on your
scent, asking you what you thought of hers. You stammered a bit, but you
managed to tell her that you thought it was sweet and she smiled and returned
the sentiment, giving your shoulder a gentle touch before leaving. You didn't
understand it, but you had walked home on cloud nine that day and you were
practically floating through the house until Ritsu's  must brought you back to
your senses.

You give yourself a quick sniff and sure enough Tsubomi's flower scent was
still lingering on your shoulder. You coward a bit and try to sneak into the
bathroom before Ritsu could catch the scent on you when you're suddenly faced
to faced with him in the hallway. His face was flushed red and his eyes were
dilated and his scent nearly choked you. He growls and starts to close the
distance between you two and you stammer and try to  explain the scent, but
your words fell on deaf ears. He drags you back to his room and before you know
it you were on his bed, stripped and filled with his cock. He wasn't gentle
either and he kept your head plastered to the pillow as he drilled you from
behind

“Nii.. Nisan..“  he growls the name as the second round of seed spurts into
you.  His thrusting slows finally, but you knew it wasn't over. It's never over
this soon no matter how many times you already came.  You feel his once
bruising grip on your hips slacken before your lower half to flops to its side
and the sudden relief of pressure brings an ache to your knees. Still you just
lay there ignoring  the gross cooling mix of fluids between your thighs as you
catch your breath, or at least try, but doesn't give you a moment to rest. He
twists your body, guiding your leg over his shoulder and in a sudden fit of
embarrassment you reach down to try and cover yourself with your shirt only for
Ritsu to snarl at the offense. You snatch your hands away and stutter out an
apology but he is already leaning forward and taking your wrist in his hands. "
r-ritsu no-mnh-" He cuts your protest off with a hard kiss and you whine but
obediently stop talking. He pulls away, expression dark and eyes narrow as he
squeezes your wrist in a silent order.  Don't. Move . You wince at his grip but
you stay put and after a moment he releases you and lowers his head down to
your neck . You tilt your head to the side to give him space and he sniffs
before letting out a quiet growl. " you still smell like her.."

Your heart drops to your stomach as he twist your body until you're flat on
your back and nestles himself between your legs. You whine loudly when you feel
him prod at your sore entrance and when he slowly starts to seeps back into you
he lets out a shaky breath against your neck while you give a choked sob as
overworked nerves fire off inside of you. He silences your cries with his lips
as he pushes in deeper and deeper until your hips meet in a mix of sweat,
 slick, and cum. You grip the sheets as your eyes screw shut.  And then he
starts to move.

It starts of gentle, like he always does but gentle never last. Soon the slow
swaying of hips quickly devolve into hard lust filled thrust, drowning out your
pants and ragged cries are with the sound of skin slapping skin and the
headboard banging against the wall.  92%  He moans are like heated gravel in
your ear  and you whine as you feel your head began to cloud, his scent seeping
through your nostrils and infecting your brain.   95%  Soon the painful stabs
of over stimulation melt back into pleasure and your vision grows  spotty. Your
quiet whines and hics of discomfort shift to raspy moans and Ah.. there it is.
That feeling deep inside you, the electric heat pulsated throughout your entire
being and made it impossible to think. Deep down you wondered if you allowed
Ritsu to keep doing this just so he could take you to that place.The place of
pure. Unbridled pleasure.

   Your thoughts fade to mush as they're fucked out of your head until nothing
was left but carnal instincts. They urge you to arch up towards your alpha, to
grab, moan, and cry for more. It hurt and felt good and it hurt and felt good
and you grip his shirt as the mix of sensations coupled with his scent drag you
further down. He presses his lips to yours and your head spins until all you
thought became Ritsu. Ritsu’s scent, Ritsu's tongue, Ritsu touch,  ritsu
ritsuritsu.
 
Ecstasy 100%
 
Your vision goes white as you're violently shoved over the edge once more with
a throaty wail. Your power crackles and pops in the air as the bed sheets tear
beneath you. Ritsu lets out his own shaky moan, hips slamming into yours with a
primal need before once again filling you with his release. You let out a
grateful whine. It felt good. It felt right to be filled with Ritsu cum. It
left a bubble of pride in your chest as the omega in you assured you of your
good work. Your power fades slowly as his own weaker but more intense aura
licked at yours and set fire to every inch of your skin. He lowers his head to
nose at your neck and licks and nuzzles and when he pulls away his expression
is soft  " its gone..."
Words were never you strong suit once you reached this point in intimacy, so
you resort innate sounds, namely purring as he leans down to press the sweetest
kiss to your lips. It was soft and slow. Careful. Not anything like the violent
smashing of lips and teeth and tongue from earlier. It was the indication that
he was starting to calm down and return to his usual self. Still his movements
did not stop all together and you feel him start to reharden inside you, but
there was no fear this time.
 He starts to move once more but this time it's slow, careful,  loving. Even
his aura had shifted from trying to engulf you to gently tickling the nerves
just under your skin. He leans close to swipe his tongue against the still
flowering bruises, kissing and gently licking at each one in a silent apology
and you let out a pleased sigh as you come down from your erotic high. Your
voice returns in soft pants and grateful hums. He whispers in your ear how much
he loves you and you're sent to the sweet embrace of orgasm once more, the
waves that shook your body and halted your breath more gentle than the lightest
touch.
 
 Once your done from your final ascension he slowly, careful pulls out of you
before laying at your side. Your body, worn, broken, damp and sore is pulled
into his arms as you're covered in his scent and he in yours. He kisses your
eyes, licks at your tears and murmurs soft apologize against your lips. He's
sorry. He just couldn't stop himself. He'll be gentle next time. I love you
niisan. I love you. I love you. You're mine. Mine.  mine.
 
You reach up to touch your fingertips to his cheeks. Your lips pecking his as
you let the sweetness of sleep whisk you off.
 
Im yours.
