Summary
     Gou likes messing up with her brother. And Sousuke enjoys that too.
     Basically a "let's all appreciate how good Rin looks wearing panties"
     kind of fic
Notes
     This fic was written in the wee hours because I have no control over
     my life ;-;
     and if you were wondering about the title... yes it is a horrible pun
     and I have a lame humour
     Please enjoy this little fic, comments and constructive criticism are
     always welcome and appreciated!
“Dammit Gou!” the redhead swore louder than he intended to gaining the
attention of his roommate: which was the last thing he wanted in that moment.
“What happened Rin?” Sousuke asked with sincere concern in his tone. “Ehm
nothing” the red replied hesitantly.
Yet Sousuke knew better and stared at him interrogatively. “I said it’s
nothing!” came his reply as he could feel his face heat up.
Sousuke still had strong doubts, so he started approaching Rin. He felt
cornered. He tried covering the bag he was unpacking with his body, making
Sousuke even more suspicious.
However he failed miserably: in order to not let Sousuke see, Rin moved in such
a way that he knocked the bag over making it fall on the floor. Much to Rin
displeasure the bag content scattered on the floor; the incriminating item he
struggled to hide was now showing on top of a pile of clothes.
Rin gulped and looked at it, which prompted Sousuke to do the same. The black
haired guy swallowed and the tip of his ears got faintly red.
“Are those Gou’s? I would never imagine her wear-” he voiced his mind, more to
break the awkward silence than actually wanting to know.
“Sousuke you dumbass!!!” Rin shouted.
At first Sousuke thought he was mad for what he said about his sister- after
all he knew how protective Rin became when it came to Gou. Yet when he turned
to face the redhead, all the pieces suddenly clicked.
That were not Gou’s. Seen the colour on Rin's face, those must have been his.
Sousuke walked towards the infamous panties and examined them from near. They
were really simple but cute and somehow kinky. It was a plain black silky like
material: the waistband had a ruffled white lace and on the back there was a
heart-shaped hole.
Finally he picked them up and headed to Rin. “Put them on” he ordered; Rin
would have refused with all his might, but the heated look in Sousuke eyes left
no room for protests.So Rin snatched them from his hand and directed to the
bathroom. Minutes passed and Sousuke started worrying about Rin spending too
much time in there.
“Hey babe is something wrong? I didn’t mean to push you into anything” he asked
sweetly.
“Jeez Sou do you think I’m a innocent virgin… I just need to work something
out..” he replied not wanting to admit that he was embarrassed for how small
and revealing everything felt.
The bathroom door slammed open and his boyfriend, clad only in a tiny girly
undergarments, showed himself to Sousuke's hungry eyes. In that moment he
blessed all the gods of female lingerie that thought of something sexy like
that.
“You look stunning” he complimented and before Rin could reply he scooped him
up, attacking feverishly his lips. Rin returned as passionately the kiss
letting Sousuke carry him towards the desk where he made the redhead sit.
He interrupted the kiss and began to caress Rin’s back along his spine; when he
got to his lower back Sousuke’s fingers dropped quickly between Rin cheeks
using that appealing hole on the panties back.
He started stroking the sensitive skin there and without wasting time Sousuke
trailed his fingers lower pressing the tips to Rin’s hole.
In the meantime Rin buried his face in the crook of Sousuke’s neck and there he
began to work at his collarbone licking and sucking. Slowly Rin traced all his
neck reaching Sousuke ear where he nibbled at the lobe before planting quick
and messy kisses along his jaw. The redhead was starting to get impatient so he
kissed lightly Sousuke and focused on the area just below his chin knowing that
was Sousuke sweet spot that would have driven him crazy. And that was what he
got. To make his needs clearer Rin grinded his hips onto Sousuke ones, feeling
he was as aroused as he was.
“Please Sousuke..” Rin begged.
“That is not fair Rin” was his boyfriend strained reply, because he knew how
weak made him hearing Rin beg.
That is why he pushed Rin down on the desk and he rejoiced at the sight. Rin
had a flustered face and hazy, heavy lidded eyes, his nipples were perked and
his half erection straining in the panties. It was downright erotic.
Sousuke leaned onto his body to start littering Rin’s torso with small kisses,
slowly inching lower, the further he reached, the wetter his kisses became.
Content sighs escaped from Rin’s mouth.
When Sousuke reached the waistband, he turned his face to look intensely at
Rin, as to search some kind of reassurement. Rin’s parted lips, together with
his pleasured expression, was enough to let Sousuke go on with his
ministrations: in no time the black haired boy started mouthing over Rin shaft.
The sensation had Rin moan louder since Sousuke was far too good and the smooth
feeling of silk only added to his pleasure. Now he stood completely erected,
his member resting on his lower abdomen as the panties restrained it.
Sousuke hot mouth wandered even lower, he dropped to his knees and parted Rin’s
legs wider.
“S-Sousuke..” Rin whispered clearly short on breath. Sousuke hummed in response
sending waves through Rin’s body as he worked his hole through the fabric. He
took his sweet time pleasuring him, occasionally poking at it with his tongue
which resulted in Rin emitting broken sighs.
Sousuke was enjoying it too much because he felt already close even without
touching himself. He always felt pleasure from getting all this reactions from
Rin and in general pleasuring him, sending him high. It was romantic and
selfish as well, because Sousuke knew he was the only one to get Rin in such
state.
Rin whimpers interrupted his trail of thoughts. “Sou please… I’m close..”
“Hang in there baby” he replied huskily while fumbling in the drawers and
getting out a bottle of lube.
He abandoned his kneeling position to stand up between Rin’s legs pressing his
hips into his crotch making the redhead hiss.
Sousuke opened the bottle up and worked his pants down his hips, just enough to
free his shaft.
“..Hurry uppp” Rin incited.
Speeding up Sousuke coated his right middle finger in lube. Then he poked at
Rin’s hole with it quite easily slipping in the tip. He positioned his free
hand on Rin inner thigh to steady himself and assure his legs stayed parted.
The desire in Rin’s burgundy orbs was raging and when he licked his lips he
couldn’t think straight anymore. He bent over and their lips collided in a
messy, passionate kiss.
Sousuke began to pump his hips grinding their lengths together. Rin nibbled at
Sousuke lower lip gently rolling it between his teeth. Sousuke grunted as gave
an harsh thrust, then he slanted his mouth on Rin’s neck biting and kissing
frenzily while he pushed his finger deeper inside of him. Rin arched his back
and took a sharp intake of breath.
“... more”.
In that moment Sousuke separated from Rin’s neck and freed the redhead painful
erection from the panties. After squirting a bit of lube from the bottle, he
started palming their dicks together. At the same time Sousuke rotated his
finger scraping Rin’s walls making him moan wantonly.
The rhythm Sousuke’s hand increased and became more and more irregular, a clear
sign he was nearing the end. One of Rin’s hand joined Sousuke one working to
get both off. Sousuke thanked him silently sending him a look full of love and
appreciation and Rin replied with an half smile cleared his lips.
Soon after his dear expression was replaced with a far filthier one as Sousuke
started flexing his finger in all the right way to stimulate Rin’s weakest
spots. The redhead lips parted to release a strangled moan and his hips bucked
up in response to Sousuke inner stimulation.
Rin bucking hips to meet Sousuke’s movements caused Rin to grind his member
with his boyfriend one, earning a low groan and a strained call of his name.
With that Sousuke emptied himself, sperm leaking from his hand. The faint
tightening of Rin’s inner walls was a sign that Rin was close too. In fact
throwing his head back and emitting a long sigh he came coating the already
dirty hand and his stomach with thick spurts of semen.
Sousuke cautiously exited Rin and leaned in rejoicing in his boyfriend
satisfied expression. He then combed some sweaty strands away from Rin’s face
to place feather like kisses on his forehead, nose, eyelids and chin. (That
always made Rin smile like an idiot and his heart flutter with joy for how of a
dork his boyfriend was.)
Rin wrapped his arms around Sousuke, who buried his face in his chest still
shaking from his afterglow.
After he had regained some breath Sosuke managed to admit: “Wow that was really
great! You looked so helpless and desperate”. Then he looked at his boyfriend,
smiling fondly.
Rin blushed furiously and turned away, then he whispered more to himself than
anything: “Yeh I’d like to see you in my place”
Sosuke flashed a grin and began to tug off the panties from Rin body,
afterwards he dashed off leaving Rin alone and butt naked.
When Rin realized he flushed completely and cried
“NO SOUSUKE NO THAT WAS NOT WHAT I MEANT!”
