Summary
     Ever since they’d started dating, this had become something of a
     routine. Of course that made it no less nerve-wracking, and Teru
     spent hours agonizing over what to wear every time. But the point
     still stood.
     Nearly every Friday Teru would go straight from school to Mob’s
     house. They would go get ice cream, or cake, or some other sweet
     treat. They would eat it together and sometimes play footsie under
     the table. Teru would pay the bill, always, just because he liked
     getting his boyfriend nice things. And then they would go back to his
     apartment, where the real date could begin.
Notes
See the end of the work for notes
He changed in the bathroom at school, which was, to be honest, kind of
embarrassing. But no one saw him doing it, so there was no one to tell Mob. And
it wasn’t as though Teru had time to go home to change, and he’d  definitely
not go on a date in his school uniform.
Summer was in full gear, and Seasoning City was hot and muggy outside. He used
it as the perfect excuse to wear a tank top he’d recently bought (the
watermelon print was  perfect)  and a pair of shorts he knew would make Mob
blush. The fact that Mob, on the other hand, would likely wear his own school
uniform was irrelevant. Mob looked best with his clothes off anyway.
Strolling down the sidewalk, Teru found himself whistling. He was very much
looking forward to this evening. Not just because Mob would be sleeping over -
though that was a rare treat.
As he approached Mob’s neighborhood, he saw someone standing near the edge,
leaning against a low wall. They were the right height and stature to be Mob,
but would Mob really be waiting for him outside? The unflappable Mob?
Yes,  Teru realized.  He would. He was.  His boyfriend’s gentle enthusiasm
warmed his heart.
“Teruki,” Mob said as soon as he caught sight of him. “How was your day?”
“Long,” Teru admitted. “I couldn’t wait to see you, so I felt like the day
dragged on.”
Mob’s eyes widened fractionally before dropping to the ground. Teru smiled,
knowing that he’d both embarrassed and pleased the shy boy. “C’mon,” he
continued. “There’s a new ice cream place near my house, I thought we could try
it out.”
“Okay,” Mob agreed. He followed a half-step behind Teru the whole way, and Teru
knew that part of the reason was because of his outfit. Just because Mob always
bottomed didn’t mean he couldn’t, ah,  appreciate  Teru’s assets.
Dating had never been like this before for Teru. Girls were fun distractions, a
way to reaffirm his own powerful position in life. They’d always been
interchangeable for him, though he knew now in an abstract sort of way that
that’d been unfair to them. They just hadn’t been  interesting  enough to
really fascinate him
On the other hand, Mob was nothing if not interesting. And adorable, and
unassuming, and so so pretty with blood dripping down his face.
They reached the ice cream parlor before long, and Teru held the door open for
Mob as they walked in. There was a wide array of choices, and Teru actually had
trouble picking. Mob just selected vanilla, which he supposed made sense. Mob
loved being able to still taste the cream.
With Mob’s milkshake and Teru’s mint waffle cone paid for, they decided to sit
outside. The little tables were picturesque, surrounded by potted flowers. Teru
was a bit sad he wouldn’t be able to see Mob licking his sweet treat all
eagerly, but the small smile on his face after every sip was still heart-
wrenchingly adorable.
“The body improvement club started something new today,” Mob said after a
while.
“Oh? What was it?”
“It’s a thing where you sit on a special ball instead of a chair. Except they
replaced all the chairs in the clubroom, so now the telepathy club members are
stuck falling over all the time.”
Though Teru didn’t know Mob’s friends well, he’d met them enough to have a
pretty good mental image of their antics. Snorting, he said, “How does sitting
on a ball help with body improvement?”
“It’s a core muscle exercise…”
Their conversation continued, happy and easy, until Mob noticed Teru’s cone
dripping ice cream all over his hand. Suddenly he stopped talking and started
staring. Following his line of sight, Teru jumped and laughed at himself.
“Whoops, I didn’t even notice,” he admitted, chagrined.
“Can I?” Mob swallowed, his voice so tiny Teru could barely hear it.
“Hmm?” Looking back up at Mob’s face, Teru watched him lick his lips and
understood.
“ Oh,  in public?” Teru grinned as he held out his hand for Mob. “Naughty
naughty.”
Despite the teasing Mob leaned forward, almost like he couldn’t help it. He
seemed transfixed by the drips of pale green going down Teru’s knuckles.
Slowly, he licked the back of Teru’s hand, a small noise escaping his throat as
he did.
Fuck, maybe this wasn’t such a good idea. Teru could already feel himself
getting hard; curse his teenage hormones. But Mob was too damn tempting to pass
up, especially when he got in a mood like this.
Cleaning between Teru’s fingers was harder, given that he was still holding the
cone. Mob wormed his tongue between them, all soft, wet heat, and Teru felt
goosebumps raise all along his arms. Even if someone had seen them and was
staring at that very moment, he wouldn’t notice. He was transfixed by Mob, the
little furrow between his brows…
“That’s it,” Teru said, quickly pulling his hand away. “You’re done with your
milkshake.”
“Huh?” Mob blinked a couple of times, eyes gone hazy. “Oh, okay.”
Now they were in a bit more of a hurry. Teru willed his erection down just so
that he could walk a bit faster, and Mob had to practically trot to keep up.
They were so close to his apartment, but even as they climbed the stairs in the
building it felt too far.
Just a couple more steps,  Teru told himself,  and then you’ll have privacy.
Then they were through his front door, and Teru was kissing Mob even before it
closed all the way. Mob’s mouth still tasted like ice cream, the faintest hint
of mint teasing him.
“So good,” Teru cooed between kisses. “I can’t wait to take you apart.”
With Mob’s lower lip clutched between Teru’s teeth, there was nothing to muffle
his small whimper.
They stumbled into his living room, awkward and tangled together. Teru was
trying to unbutton Mob’s gakuran, and Mob couldn’t seem to untangle his hands
from where they’d clenched in Teru’s tank top. A hint of copper had joined the
flavors in Teru’s mouth, probably because he wasn’t being careful with his
teeth. He tongued the small cut in Mob’s gums, relishing the way it made Mob
flinch.
Finally, they were in the living room, and Mob’s chest was exposed to the air.
Teru ran a proprietary hand down his chest, but stopped himself from properly
groping Mob. There’d be plenty of time for that later. “Strip,” he said,
stepping away.
Again, Mob took a moment to process the command before he obeyed. Teru went to
a cabinet in the meantime, and pulled out a box of their toys. While he didn’t
often use implements to hurt Mob, preferring to stick to his bare hands, he’d
still collected some  interesting  things.
Pulling out a couple of his favorite items, Teru turned around to find that Mob
hadn’t quite been perfectly obedient. Clicking his tongue, Teru shook his head.
“Take it all off,” he reminded Mob.
A slight tremble went through Mob’s petite frame, but he still hooked his
thumbs into the waistband of his white briefs. He pulled them down slowly,
stepping out with first one leg, then the other. It left him completely
exposed, his small cock already curving upwards and filling with blood. It made
Teru’s mouth water.
Don’t get distracted,  he reminded himself. Stepping forward, he slid the
simple collar around Mob’s neck. It was blue, and meant for a dog, but he was
saving up for a better one. Nothing but the best for his Mob.
“Come on,” Teru said, striding purposefully towards his bedroom. He heard Mob
shuffle along behind him, and knew the boy was uncomfortable with how  breezy
everything was at the moment.
Once they were in there, Teru directed Mob to lay face-up on the bed. He didn’t
even need to tell him to put his wrists together for the cuffs; he was so eager
to be bound that Mob had them up and silently pleading for leather even before
Teru could speak. On the other hand, getting him to spread his legs was a
challenge.
“You don’t want me to force you, do you?”
Mob shook his head, his bottom lip wobbling. “B-but we haven’t, with my pants
off…”
“I know,” Teru stroked Mob’s cheek gently. “If you don’t want it, we don’t have
to.”
“No, I want it,” Mob confirmed. He eyed the device warily, but slowly moved his
ankles. The only thing more adorable than his reluctance was his eagerness to
please.
In the end Teru put the spreader bar on, and was sure to use just a bit more
force than necessary. Now Mob’s ankles would be bruised under the unforgiving
plastic, and he’d be even less inclined to try to close his legs. His erection
was clearly bothering him, but Teru ignored it.
That done, Teru was free to add the final touch. Mob had to open his mouth wide
to accommodate the ball gag, and Teru knew it would make his jaw ache before
long. He couldn’t wait until the drool started pooling in Mob’s mouth, bubbling
up at the corners of his lips…
Of course, he had to give Mob something to drool over before that would happen.
So Teru did what any good boyfriend would do, and punched Mob right in the
vulnerable tummy.
Arching his spine, Mob cried out. The gag absorbed most of the noise, but Teru
could still hear it, and he smiled brightly. “I love when you’re all healed up!
It gives me so much skin to work with.”
“Mmhmm,” Mob hummed.
Next Teru aimed his palm so that the breath was knocked out of Mob’s lungs. He
pressed both his hands down immediately afterwards, felt Mob’s diaphragm
struggle to move under his weight. “Think I could choke you like this?” Teru
asked.
“Nnnn - hhgk!” There was a spit bubble, right as Teru pinched Mob’s nose and
forced him to try to breathe through his gag.
Just as Mob’s cheeks started to turn a blotchy red, Teru released both his nose
and his chest. Mob heaved in huge breaths as Teru nuzzled his cheek. His Mob
was such a good boy. The collar brushed against Teru’s face as he drew away,
and he thrilled at the sense of possessiveness that went through him.
He gripped one of Mob’s forearms, forcing both his hands up above his head. Mob
kept them there obediently, even when Teru harshly bit his chest. Mob jerked,
of course, but he didn’t let his arms move.
Again and again Teru bit down. At first he avoided breaking skin, and sucked
harshly instead to ensure that he left behind marks. But he was intentionally
avoiding Mob’s nipples, and the poor boy was making needy sounds as Teru crept
down his ribs. Well, he should give Mob treats in reward for good behavior,
shouldn’t he? So he licked one of Mob’s nipples, felt it pebble under his
tongue, and bit until he tasted blood.
Strange, how Mob could be so eloquent even gagged. His mewling sounds said both
that he was in pain and that he was enjoying it. His squirming let Teru know
that he was skirting the edge of  too much,  but hadn’t quite crossed it. It
likely helped that Mob was always so quiet, was used to communicating with body
language.
“Do you feel what you’re doing to me?” Teru asked, once both of Mob’s nipples
were bloody. He straddled Mob’s belly, just to let him feel Teru’s dick through
his shorts.
Wriggling even more (Teru was putting pressure on that initial punch, wasn’t
he? Good) Mob nodded. Teru rocked his hips gently, not trying to get himself
off, just  feeling.  “Can I fill you up, Shigeo? It’s been so long, I’m sure
you’ll be nice and tight for me.”
Immediate, eager nodding. Mob’s pupils were blown so large his eyes were almost
totally black.
Teru climbed back off of him, then grabbed the bottle of lube on his bedside
table. He drizzled a generous helping over his fingers, but kept it close by.
He liked Mob so sloppy with lube that he dripped everywhere.
When he slid the first finger in, Teru laid another blow onto Mob’s belly. He
loved feeling the muscles tighten around his digit, loved imagining how good
it’d feel on his dick. Pumping his finger in and out, slowly, Teru allowed Mob
to catch his breath.
Another finger, probably too soon after the first. Mob liked a bit of burn,
though, and the spreader bar meant Teru could take as long (or short) as he
liked. This time he punctuated thrusts with nips to Mob’s thighs, not as harsh
as the bites on his chest. At least, not yet.
Secretly, Teru thought that this part was his favorite. Having his cock inside
Mob might feel better, but it was harder for him to stay in control. Scissoring
his fingers, on the other hand… leaning back to see Mob’s puffy, pink insides,
kissing his navel but not touching his cock… resting his cheek against Mob’s
thigh and lazily stroking his prostate…
Tears were starting to well in Mob’s eyes. He was probably feeling a lot of
things, and he hadn’t even gotten to come once yet. Well, Teru liked wringing
more than one orgasm out of him, so he might as well. But of course he wasn’t
going to touch Mob’s dick. No, he was much more creative than that.
Mob just about screamed when Teru went straight from two fingers to four. And
hitting his tummy again, at the same time -
Desperate gagging sounds came from above him, a different pitch than normal.
Teru acted on instinct, swiftly undoing the gag from around Mob’s lips.
And then Mob was sitting up, a veritable torrent of pink-tinged ice cream
coming back up. It covered him, probably stung the open wounds in his mouth and
on his chest. He coughed, and shook, and in between heaves repeated something
over and over.
“I’m sorry, I’m sorry.” The words were slurred,  I’m sowwy,  but
understandable.
“Aw, little calf,” Teru said, stroking Mob’s hair. “Hush, it’s okay. It was my
fault.”
Actually, he was kind of worried about the pink in the vomit. Had he made Mob
bleed internally? He didn’t want to cause serious damage, but at the same time,
seeing Mob soaking wet was seriously affecting his concentration.
Carding his fingers through Mob’s hair, Teru waited until he hiccuping sobs
subsided. With tears caught in his eyelashes, Mob looked up at Teru, almost
shy. He made no move to wipe the remaining creamy droplets off his chin. “D-do
we have to stop?”
His plaintive tone actually made Teru’s heart skip a beat. Leaning forward, he
kissed Mob softly, ignoring the fact that he was filthy. “Of course not,” he
murmured against his lips.
Carefully guiding Mob to lay back down, Teru finished up preparing him and
pulled on a condom. He kept it quick this time, sure that he shouldn’t wait too
long before administering aftercare.
That meant Mob was  super fucking tight  when Teru finally pushed into him.
Using the spreader bar as a handle, Teru forced Mob’s legs up, stretching them
nearly flat against his body. Thank god the body improvement club had Mob doing
stretches as well as weight lifting.
Since the gag was off, Mob was able to be a lot more vocal. He chewed his own
swollen lips in an attempt to quiet himself, but he still made the sweetest,
tiny noises when Teru’s dick brushed past his prostate. Keeping one hand on the
bar, Teru clawed down the back of Mob’s thigh with the other. “Yes, god, it
feels like you’re sucking me in.”
Blood under his fingernails. Had he bloodied Mob’s leg accidentally? Oops,
there went his control.
Squelching and delicious slipperiness between them. Lube and puke and then -
Unable to take any more, Mob came, a sound not unlike a squeal spilling from
his lips. The white semen mixed with the milkshake from earlier, and Teru
couldn’t resist the urge to smear it into his skin. “Look what a mess I’ve made
of you,” he said proudly.
After only a couple more thrusts Teru followed Mob over the edge. He wanted to
hold out, but he couldn’t help his age.  Someday,  he promised himself,
pressing as deep into Mob as he could go.  I’ll fuck him through multiple
orgasms. I can do it.
Today, however, both Teru and Mob were spent. At least for the next hour. Teru
pulled off once the condom got too gross to leave on any longer, and then began
their aftercare routine. This time, he had to make a mental note to strip the
bed and wash the sheets as he carried Mob to the bathroom. But he didn’t mind
at all.
Relaxed and content, Mob peppered kisses on Teru’s cheeks while they waited for
the bath to fill. Teru was definitely counting this date as a success.
