He wants them to experiment with kink and try new things in their relationship, and he thinks this is the perfect opportunity to do so.

Later that night, when their friends and family start to arrive, he finds himself giddy with excitement at the thought of them having this dirty little secret and doing something so taboo while surrounded by their loved ones.

He goes back to their bedroom and finds that the remote is missing from where he'd left is and smiles with glee.

When he goes back to their little get-together, he eyes his boyfriend, anticipation curling in his gut as he wait for those delicious vibrations to come.

His boyfriend, however, doesn't spare him a glance, and he finds himself caught between feeling offended he's being ignored and turned on by the sudden shift in their dynamic.

He tries his best to put it out of his mind and be a good host, mingling with their friends and family and trying to carry on a conversation. Though his mind keeps straying back to the toy inside him and he wonders what is taking his boyfriend so long to try it out.

Halfway through the night, his older brother approaches him, a rare smile painting his features as he brushes a hand through his hair.

"Yuuji. How are you?" Yuuji smiles up at his older brother. If he's being honest with himself, he misses his company and wished they spent more time together, but for whatever reason, Choso hasn't come around much since he moved in with his boyfriend

"I'm alright. It's been a while. How have you b- ah!" Yuuji's words are cut off by a desperate moan pushing past his lips as he's hit by a wave of vibration. His head whips around in search of his boyfriend. 'Why now?'

"Are you ok, Yuuji?" His eyes come back to meet his brother's, and Yuuji can't help but notice an odd, almost knowing look in his eyes.

"Y-yea I'm... I'm fine." "You sure, little brother? You look a little..... flushed." 'There's that look again. What is that?'

For some reason, Choso looks as if he knows something nobody else knows, and Yuuji wonders what it is he could be hiding. "I'm alright, big brother. Just uh- I'm just a little hot, that's all." Yuuji tries to explain away his odd behavior.

This isn't what he expected it to feel like, and it was already becoming overwhelming having that constant stimulation. He bites his bottom lip and tries to focus on Choso's words but he's unable to.

He's flushed, sweating hard, and just as he thinks he might cream his pants, the settings change, the steady vibration becoming a rhythmic pulsing. He doesn't know what's worse, being edged in such a cruel way or the fact that he was about to cum in his pants-

While trying to hold a conversation with his brother. He can't focus on a thing coming out of Choso's mouth, and of course, Choso notices. He gives him that weird look again, and Yuuji thinks it's odd how Choso watches him with an almost predatory look in his eyes.

"Yuuji. You don't look so good. Maybe we should step outside for a bit so you can get some air." His tone is suspicious, but Yuuji can't place it. He's never been good at picking up social cues, and at the moment, his mind was too preoccupied with the vibrator currently-

Making a mess of his prostate. So he let himself be pulled along by his older brother. He glances around to hopefully catch a glimpse of his boyfriend to let him know where he is going, but he can't spot him anywhere.

Choso drags him out to their backyard and over towards the lawn chairs they had set out for whenever they felt like sitting outside in the sun. He drops down into one of the chairs, intending to stretch out and expecting Choso to take the other but is taken by surprise-

When Choso crowds him up against the back of the chair. "Yuuji." There's that look again, and Yuuji finally sees it for what it is. Lust. Unbridled want. And as that realization dawns on him and he sputters to find an excuse to go back inside, the vibration increases again.

Yuuji cries out, back arching obscenely as his prostate is pummeled by incessant vibrations. "What's the matter Yuu? Is everything ok baby brother?"

Yuuji looks up, and his brother as Choso spreads his legs and slides in between them. Hovering over him as he admires the fucked out, desperate look on Yuuji's face.

"Answer me, sweetheart." Choso demands, and the vibrations only increase, crippling Yuuji's ability to form proper thoughts let alone a proper sentence. "I-it's you." He tries to make his tone sound accusatory but is unsuccessful. "You're doing this."

"You finally figured it out, huh?" Choso drops the little remote on the table beside them before pouncing on Yuuji with a vengeance. His hands are all over him, groping his pecs and pinching his sensitive nipples as Choso leaves a trail of hickies down his neck.

"W-wait! We shouldn't. Chos- nngh." Yuuji tries to reach out for the remote, but Choso slaps his hand away, knocking it out of reach. He wraps a hand around the back of Yuuji's neck, forcing him to make eye contact.

"Don't think I'm so blind that I haven't noticed Yuuji." "N-noticed what?" Yuuji questions, trying and failing to pull his push Choso off of him.

Choso grabs both of Yuuji's wrists in one large hand, pinning them above his head. "The way you look at me. The way you act so flirtatious when no one else is around?" "N-no, I don't know what you're talking about.' Yuuji's response sounds weak and flimsy even to his own ears.

"Oh you don't?" Choso uses his other hands to grope Yuuji's cock through his jeans before popping the button and undoing the zipper. "You don't."

"Choso-nii. S-stop." He cries weakly, tears welling in his eyes as he fights desperately not to cum from the relentless onslaught his prostate is enduring as well as his brother's skillful hands all over him.

"If you don't want it, then stop me, Yuuji. We both know you're more than strong enough to put up more of a fight than this. Fight me off, baby brother."

"Ch- Choso! Please- I can't. We shouldn't. What will people think?"
