Dazai disappears and grabs a chair from the kitchen, setting it down opposite the bed and tossing his jacket over it. There's something electric in the air that he loves, that sexy sense of wonder in what could possibly come next, what does Dazai have in mind for his little fantasy. The chain around his neck is a light reminder of exactly how much he wants of this, though a moment of thoughtful hesitation hits him.

"So, what are we going to do?" He asks, thumbing the large ring that connects the collar to the silvery chain.

Dazai snickers at a joke he'll never understand and takes a seat, spreading his legs wide enough for him to crawl between. A happy little buzz and a tingly feeling dance in his stomach. "You," Dazai points at him, "Are going to focus on me while I fuck your mouth open." He makes a come hither motion, Atsushi takes his first step and gets a sharp glare that freezes him in his tracks. "No, crawl." Atsushi's throat tightens, its so foolish but his brain is only now registering what's going on here, this sense of having given up power to Dazai.

He eases himself down onto his knees, hands first and never breaking eye contact with Dazai. He isn't sure what the exact feeling is but Dazai gazes at him with a curiously discerning eye. Part of him wants that to be either Dazai intentionally making him curious or thinking up new, depraved ways of breaking him. Atsushi crawls between Dazai's legs until he can curl his legs underneath himself and feel up Dazai's clothed calves to his knees until he reaches Dazai's crouch.

Dazai's stare has become muted and curious and Atsushi rests his head on the chair, against Dazai's inner thigh. A warm, gentle hand curls in his hair, squeezes his cheek and curls around his chin. "What's your safe word?"

A bit of a rush to the head, that. "Ah-, um, how does 'Book' sound?"

"Sounds good, anything you'd like me to not do to you?"

Atsushi shakes his head and squeezes Dazai's thighs. The older man sighs, a smile dancing on his lips. Dazai's hands reach down, touch his own and push them away, Atsushi tries not to seem too desperate while Dazai unzips his pants and ends up thinking about his breathing, wondering if he sounds too breathy or not breathy enough. Dazai's cock is flush against his cheek, hard and hotter then he thought, Atsushi presses his mouth against it and sighs. Dazai is going to ride him to high hell and he can't hold himself up straight.

"I just realized how much I love seeing you choke on me..." Dazai isn't looking directly at him, more wondering wistfully at the ceiling with a cute, childish grin. Atsushi stands on his knees to peck a kiss to the right of his lips and sinks back down before Dazai can refocus his attention, he's quick enough and catches the semi embarrassed glance of a dom taken a tad bit out of his element.

Atsushi hides his grin, "No, I-I actually really like it, it makes me feel-nice." What he actually meant to say was that it made him feel like a little slut, but he sure as hell isn't going to tell Dazai that, he'd die and melt into the floor to never be seen again.

"Is that so?"

"Mmhmm," Atsushi hums and licks up the base, giving Dazai the most sultry look he can only to admonish himself once he's hit the tip. This is a bit much, isn't it, even for them- Dazai giggles and pets him.

"Well then, how's this?" Dazai grabs himself and Atsushi's pushed forward until his cock is pressing against his mouth, hot and smooth. The flicks his tongue at it, salty with a hint of his own saliva.

He can't get his hands around the base, so he makes due with his tongue. He flickers against the heated flesh, sighs a little at how Dazai's eyes lower, how his teeth bite into his lip while chokes back a moan. His nose is flush against Dazai's hips and he can smell soap, something wintery with a hint of pine. His nails scratch against the rough cloth of his pants while Atsushi does all he can to push against Dazai's own fingers.

Damn there's even a heavy heat right above his stomach and leading down to his crouch, he wants it and Dazai is doing this all on purpose.

Dazai's cock is in his mouth, Atsushi's nose is flush against his hips. His eyes are aggressive, possessive, deep seated, as if he meant that last promise in the most literal and beautiful of ways, Atsushi will belong to no one else but Dazai, forever.

There's a shift forward, Atsushi is vaguely aware Dazai is fucking his mouth open, to the point where his jaw almost goes slack and his eyes are rolling back. His head is descending under the waters and Dazai must be teasing him with it, knowing he's almost there, that if he was to grab his head and begin riding his face properly he could push him down so deep, he might never come back up.

"Please," he chokes and gags until he can't breath anymore then pulls back. A long, thick white line of bubbled saliva and precum connects the two of them until it breaks in his favor and spills oh his chest. The smoky, heated groan he gets from Dazai is more then enough reason to flash his tongue out and collect what he has on his lips before swallowing it. Dazai removes his hand and pushes him down, his cock forces his throat open with a burning flash of pain and a need to bite - he resists and heads under. He's been so, so patient, waiting for this, waiting to dive into that place where nothing but what Dazai wants matters.

The spit bead link between the flushed tip of his cock and his mouth breaks before he goes back. It's so pretty down here, with a hot rush against his mouth and a weight against his head. He floats for goodness knows how long underneath the surface, the heat on his mouth welcomes his hands and he makes up what he can't take with his warm palms, until the tip is choking him and pulling him further down until his mind goes blank and all he can do is feel.

"Here, here-" Dazai pulls him away and a hot spurt hits his right cheek, the second and third against his chin and open mouth. He sighs, eyes closing as he melts against Dazai's leg. This is exactly what he wanted, not being able to even think straight and with Dazai curling his fingers against his cheek and hair. "So good, you're so perfect for me aren't you Atsushi?"

"Hmm," he purrs and rubs circles into the floor, head not high enough above water to respond.
