Summary
     On Sunday afternoons, when they've no swimming practice to go to and
     the air is still and warm, the day is theirs to waste away, and Rin
     likes to stay indoors with the curtains drawn and the air con
     blasting. He feels lazy and relaxed on those kind of days; dazed and
     drained from a week of overexertion and rage.
     Aiichirou takes those days to study, needing all the help he can get
     as he struggles through his English coursework. Rin helps.

On Sunday afternoons, when they've no swimming practice to go to and the air is
still and warm, the day is theirs to waste away, and Rin likes to stay indoors
with the curtains drawn and the air con blasting. He feels lazy and relaxed on
those kind of days; dazed and drained from a week of overexertion and rage.
Aiichirou takes those days to study, needing all the help he can get as he
struggles through his English coursework. Rin helps.
“Light of my life, fire of my loins, my sin, my soul,” Ai read from the book
laid open on the bed in front of him.
Rin smiled at Ai’s thick Japanese accent. He was sat criss-cross on the bottom
bunk, and had his arms hugging loosely around the small body sat in his lap,
grasping his shins and pulling him in close. He buried his nose in the crook of
Ai’s neck, where his hairline ended, and inhaled deep. He loved Ai’s scent,
clean and sweet but with a sensual musk of boy sweat.
“Lolita; the tip of the tongue taking a trip of three steps down the…” Ai
paused at a word he didn’t recognize, bringing his finger up to point at it-
this is what Rin was for.
“Palate,” Rin read for him.
“-palate to tap at three, on the teeth. Lo-li-ta.”
Rin began to grow distracted as he nuzzled his nose at the back of Aiichirou’s
neck, right where it met his shirt. If there’s one thing that turns Rin on the
most, it’s a person’s smell. He remembered how sharks could smell blood diluted
one to one million parts.
Rin thought of the times he had been in the room alone, tangled in Ai’s
blankets with his his hand down his pants and his nose buried in one of Ai’s
dirty shirts.
“She was Lo, plain Lo, in the morning, standing four-foot-ten in one sock,” Ai
continued reading, as best he could, brow furrowed in concentration, “She was
Dolly at school. She was... Dolores?"
"Yup."
"Dolores on the dotted line.”
Ai stretched his neck to the side as he read, completely oblivious to how much
he was tempting Rin with his scent, with the exposure of skin, with his voice.
And then he wriggled his hips a bit to get comfortable, and his bum
accidentally ground against Rin’s already hardening groin.
“But in my arms, she was always Lolita.”
Rin couldn't take it anymore. All at once, he brought his hand up to push Ai’s
hair back off his forehead, pulling the boy’s head back towards him and sinking
his teeth gently into the side of his neck. Ai gasped as the pleasure of the
bite went straight to his groin.
 
The smaller boy whined, letting the book sit forgotten as he writhed in Rin's
lap, already hard just from Rin’s mouth on his neck. His moans and groans
encouraged Rin to continue stroking the fine strands back with nimble fingers
as he sucked, nibbled, and kissed the side of his roommate's neck.
Because of his inexperience, Ai was very sensitive, reacting to even the
smallest of touches as if they were heavy stimulation. Rin knew, and decided to
take advantage of it by teasing the boy with stimulation all over his body.
Ai's arms were stiff at his sides, fingers gripped tight on to the hem of Rin's
gym shorts where they hitched up to the tops of his thighs. With the fingers
that weren't tangled in Ai’s hair, Rin tickled up the smaller boy's leg, to his
inner thigh, where he scratched long pink lines into the soft, hairless, snow
white skin.
"Ahh- mmn, Senpai!" Aiichirou was a hypersensitive mess of gasps and moans, his
wriggling body on fire as Rin continued on his neck and inner thighs.
Rin kissed his way up to Ai's ear, where he gently mouthed at and licked the
outside. Then the younger boy took initiative and turned his face to meet Rin's
lips in a quick chaste kiss. Rin chuckled before diving in for a deeper kiss,
this time open mouthed, his tongue teasing Ai's lower lip.
Ai broke the kiss with a gasp when he felt Rin's hands both swiftly slide into
his shirt and thumb at his nipples, before pinching them gently. Ai, with his
eyes still closed and mouth still opened, ground his ass down against Rin's
hard cock.
"Oh, fuck," Rin whispered, closing his eyes and resting his forehead onto Ai's
shoulder. He tried to gather his composure and self-control, knowing that if he
didn't, he would easily lose himself and hurt the tiny boy in his lap.
Whilst still rubbing and pinching at the other boys nipples, Rin scratched down
his chest, sliding down his slightly sweating tummy, grabbed tight onto his
hips, and finally, lightly palmed at Ai's hard little cock through the fabric
of his shorts.
As soon as he felt Rin's strong hand pressing at his crotch, Ai couldn't hold
it back anymore, and he began moaning between sharp intakes of breath.
"Ohh, ahh, Matsuoka-senpai, yes, yes, mmnhh, oh my g- fwahh!"
Ai's back was arched, pressed into Rin's front, and his hands were still
grasping the fabric of his shorts. He laid his head back against Rin's shoulder
to steady himself, moaning directly into the red head's ear.
With the combination of Ai's filthy moans, breathy pants, and the wriggling of
his tiny bottom in his lap, Rin could feel his self-control slowly dissolving
right before his eyes. He tried grasping Ai's hips to hold him still for a
moment to breathe, but it only made the little boy grind down harder. When one
particularly high pitched moan made Ai's pubescent voice break, Rin just lost
it.
With a deep, guttural growl, Rin grabbed and threw the kid against the
mattress, straddling over his much smaller body. Ai opened one eye to look up
at Rin, who had never before seen the smaller boy looking so fucking wrecked -
his normally tidy silver hair was a mess, sweaty and pushed up in different
directions, as was his shirt; he was deeply blushing and his nervous eyes were
half lidded; his lips were rosepetal red, swollen and parted, shiny with spit.
Rin was going mad, this kid was just too hot for his own good. He swiftly
pulled Aiichirou's shirt over his head.
Rin was losing it, ravishing Ai's neck, biting his collarbone. Ai layed there,
arching his back as Rin removed his own shirt and pants before pressing their
bare torsos together and kissing deep and desperate. Rin ran his hands all over
the little boy’s chest, down his sides, and across his tummy whilst yanking his
shorts off with his toes. Rin positioned his covered hardness onto Ai's,
grinding down on it hard enough to make Ai moan. Then he broke the kiss to
slide his sweat-slicked body down, licking down Ai’s neck and sucking bruises
all over his chest, making him gasp and fist his hands into the blankets.
Rin licked his way lower, spreading Aiichirou's thighs and holding them open;
and whoa, they're slim enough to completely fit in Rin's hands as he held them
apart. He nuzzled his face into Ai's boxers, feeling the hardness against his
cheek, getting drunk off the smell whilst his nails dug at the boy’s thighs,
surely leaving a mark.
Aiichirou cried out, half in pleasure and half in pain, biting on his knuckles,
as Rin took off his boxers and licked the head of his dick once, before rubbing
the tip and the frenum with his fingertips and mouthing at his inner thighs.
Then he put the boy’s still undeveloped cock in his mouth, sucking hard whilst
cradling his balls in his hand. Ai asked for Rin to please take off his boxers
too, and Rin laughed, because he was enjoying pleasing Aiichirou so much that
he forgot about himself. He took it off and aligned their dicks, bringing one
of Ai's hands down, lacing their fingers together so they were both wrapped
around both dicks, before going up to suck on the smaller boys neck as he
thrust into their hands.
As Rin thrust into their tight hands, Ai moaned and whined so loud that Rin
needed to silence it with a kiss. Ai had never felt so many sensations all at
once and he was feeling almost over-simulated, sometimes forgetting to breathe.
He placed his free hand on Rin's chest, spreading his legs wide and bringing
his knees up high. Rin threaded his free hand through Ai's hair as he sped his
thrusts.
Ai had tears pouring out from his eyes from the intensity, his chest heaving up
and down and he let out a breathless, silent shout as he came, shooting onto
Rin's chest before going limp. Rin swiftly pumped his dick, biting back moans
as he came onto Ai's madly blushing face; the boy cringed and wiped it off with
his crumpled shirt.
Rin collapsed beside his exhausted roomate, gently kissing the bite mark he'd
made on his warm, red shoulder.
Through heavy breaths, Ai whispered, "studying with you is distracting,
Senpai."
