Not really a bratty Shane believer, but more like
Shane being bitchy and huffy, maybe he couldn't find the car keys which made him late to morning practice, the grocery store is sold out of his favorite protein powder for the third time this month, and Ilya stacked the dishwasher wrong, or accidentally left a dirty sock in the hamper. Shane is annoyed and restless, snapping at his mom on the phone first, then later at Ilya in the kitchen, being all "It's fine, I'll do it myself then" while glaring at his boyfriend with that angry kitten face, fidgeting with the hem of his shirt and suddenly it just. Clicks for Ilya. It's- Oh. Oh.
"Go upstairs. Take your clothes off."
"Seriously? You can't possibly be thinking-"
"Now, Shane."
(Shane complains about it, dragging himself up to their bedroom, taking extra long to fold his clothes just to make a point to Ilya, who just blinks at him and tells him to get on the bed- but he does listen- of course)
Anyway not even half an hour later Shane is on his knees face down in the pillows, panting and sweating while Ilya fucks into him with deep, evil strokes that have him whining and squirming and it's so much, one hand pushing between his shoulder blades, the other a vice grip on one of Shane's wrists where it's pinned next to his head. Ilya is saying something that Shane only half understands, realizes a second too late it was a question- but Ilya's so deep inside of him, Shane can't focus, can't fucking think, he might be drooling a bit, little pained uh-uh-uh's leaving him with every filthy grind of Ilya's hips. He barely notices Ilya pushing his thighs further apart and leaning forward to plaster himself all over Shane's back until Ilya is biting and sucking at his neck, jaw, breath hot and wet on the sensitive skin there, right at his ear like "So rude, not giving me an answer. But is okay baby, I know, I know, my dick got you all stupid, huh? Such a slut for it, is what you need, yes? For me to put you in your place? Fucking take it malysh, come on, hips up, no no, you can take it, there you go-" and Shane comes so hard he can't speak for about fifteen minutes.
