[ despite the roughness that he'd started the kiss out with, it's easy enough to fall into Rex Lapis's rhythm despite what he's doing to him right now. it's a welcome distraction from the way his body is adjusting to the sudden intrusion, the sting of raw penetration eased a little by a combination of the spit-slick he'd coated the mafia head's dick with and also his own adaptability. in the face of intrusive, overwhelming pain his mind tries to put a damper on it, tries to rewire his body enough that he can focus enough to move - and Rex Lapis is big enough that he hits the good spots deep inside, so it's less effort than one might think to adjust.
it also really doesn't help that he looks just like Zhongli, and while he'd loved fucking the man's brains out last night the thought of someone as lovely and demure and sexy as Zhongli taking him instead is very, very appealing.
so gradually, the clench becomes less severe. he's still tight, still tense, but the ease of his muscles means that it's less painful on Childe's end, as well. the kiss becomes less biting, as well, but no less rough, and it doesn't take much longer for his tongue to flick out to taste the man for himself while also letting him taste remnants of his pre-cum and cock in Childe's mouth.
eventually he has to pull away for breath and when he does it's to bump his forehead against Rex's own, breathing out harsh and sharp in the space between them. there's a swear in Snezhnayan - something about calling him 'compensating' and 'asshole' - and the tears in his eyes finally spill down his cheeks, teeth gritting before he suddenly bucks, either in an attempt to dislodge the mafia head or pull him in deeper on the next thrust. ]
