@comingatthecottage because you asked for more (based on this post from @shaneseggs and also @allstarrocks's excellent tags)
"Come here, solnyshko," Ilya says, voice firm, pointing at the spot between his legs with one hand, a glass of vodka in the other.
Shane goes to him, crawling on all fours, a dog crawling to its owner. He sits obediently, watching as Ilya tilts the glass to his mouth, tracking how his Adam's apple bobs as he swallows, entranced. Shane doesn't really understand the appeal of vodka, why exactly Ilya likes it so much beyond it being a cultural thing for him, one of the only things that ties him to Russia that isn’t painful, but he can’t deny the image of him drinking it is appealing.
Ilya clicks his tongue and makes a come hither motion, signalling for Shane to kneel up so Ilya can lean down to kiss him. He winces, just slightly, at the aftertaste of vodka he can taste from his lips - an uncontrollable, momentary hesitation that is almost instantly suppressed, but of course Ilya notices anyway.
Ilya leans back, regarding him, his hard gaze making Shane’s spine straighten in anticipation, or maybe fear.
Shane obeys, parting his lips, eyes locking onto Ilya’s face.
“Tongue out, too. I want to look at you.”
He flushes, but he does what Ilya says, lolling his tongue out of his mouth, feeling even more like some silly puppy come to beg for scraps at Ilya’s hand.
He watches as Ilya takes another sip of his drink, but this time he can tell he doesn’t swallow it, holding the liquid in his mouth instead. He furrows his brow, momentarily confused, but then Ilya bends down again, and it clicks just a second before he actually does it that he's going to spit the vodka into Shane's open mouth.
He holds it there in his mouth, letting the acrid taste of it burn his tastebuds, waiting for the signal from Ilya that he should swallow, trying not to let his discomfort show. Shane doesn’t understand this inexplicable need of Ilya’s to force feed him alcohol. He hates the taste of it, but he loves Ilya more, so of course when Ilya motions for him to swallow it he does.
He opens his mouth again, proof he's done as he was asked, waiting for Ilya to praise him, but instead he looks down at him, his disappointment evident on his face.
"I thought you were going to be good for me?" he says, his mouth slanted in disapproval.
Shane's heart beats faster in his chest. "But, I was, Sir?"
"You are telling me I am wrong now too?"
"If you are sorry, you will do better this time."
Shane drops his jaw again, waits for Ilya to take another sip, braces himself for the shock of alcohol on his tongue. But unlike last time, Ilya grabs his face harshly, squeezing his cheeks until Shane is forced to open his mouth wider to lessen the pain. The pain makes him jerk, as does the surprise of the alcohol being spit into his mouth again before he's ready, but like before he swallows obediently, even though his cheeks and throat burn from the humiliation and the vodka, respectively.
Again, he waits for praise for following instructions, for Ilya's eyes to go soft and his hands to pet his head gently, but again he's disappointed.
"Why is this so difficult, hmm? Don't you want to obey me?"
"I do, Sir, I promise I do!" he says, desperate, his head fuzzy from the combination of the alcohol and the disapproval written all over Ilya's face.
"Maybe I am being too soft with you," Ilya muses, as if he hasn't spoken. "Maybe I need to take a firmer hand."
Suddenly he's being grabbed, his head held in the crook of Ilya's elbow, like he's a wild animal that needs to be restrained. He struggles, disorientated by the suddenness, which only makes Ilya grasp him tighter. He tries to jerk away when Ilya spits the vodka, gagging at the taste and closing his mouth against the stream dripping from Ilya's mouth to his. In response, Ilya pinches his nose shut, and then Shane is gasping, inhaling through his mouth desperately and coughing as he gets a mouthful of vodka rather than the oxygen his lungs desperately crave. After a few seconds he gets control of his panic, making himself go limp, swallowing the last dribble like a good boy.
Ilya releases his head and Shane slumps forwards, his breathing ragged. Vodka and spit dribbles down his face and neck, making him shiver at the coolness.
"See," he says condescendingly, "This is why you should obey in the first place, solnyshko, I would not have to be so rough with you if you were a good boy, hmm?"
Shane nods, still coughing the vodka from his lungs, unable to remember whether he had been good or not, having no choice but to trust Ilya to tell him right from wrong and up from down.
"You will obey first time next time, yes?" Ilya asks, pulling his head up by his hair, so he's forced to bear his throat. "No more silly protesting?"
"Yessir," he says hoarsely, head swimming, though whether from the alcohol or Ilya's dominance he isn't sure.
