a-ning have always lamented the unfortunateness of his mouth being too small to suck his mo ran gege’s too big of a cock

so it was to his delight when he saw a thread of how to suck dick, immediately running to his gege’s room to try it out

mo ran was laying in bed scrolling through his phone and didn’t notice a-ning going inside his room causing him to drop his phone when a-ning crawled over him, sitting on his thighs

“a-ning, what are you doing?” mo ran asks when the younger moves to pull his zipper down

don’t get him wrong, he loves having sex with a-ning but this is the first time he’d seen him just… quite frankly pounce on him

because usually it takes a little bit of coaxing or a-ning shyly teasing him before mo ran gets to rail him into oblivion

a-ning holds his own phone, face scrunched in determination as mo ran reads the words on the screen under his breath

he almost choked on his own spit — his a-ning will really do anything to give him a blow job huh?

they’ve tried it so many times before but a-ning’s lips are just so small, the edges of his mouth already straining with just mo ran’s tip inside

“gege should read it to me so i can follow” a-ning’s face went aflame, looking down to unzip mo ran’s zipper before even waiting for a response

mo ran inhales, the thought of instructing a-ning this way was so fucking hot that he almost popped a boner

mo ran licks his lips before reading, “step one, suck it while it’s soft…”

a-ning nods, he’s read the first part which convinced him that giving his gege a good blowjob was plausible

he takes mo ran’s still soft cock in his hands, giving a tentative lick before taking him in

although his gege was soft, he was definitely still larger than average. however, taking him in not hard is easier

mo ran continues to read as a-ning follows obediently, the rest of his hands stroking mo ran’s shaft into hardness and squeezing every once in a while with his thumb and index finger to put pressure

mo ran hisses as he steadily grows hard, looking past the phone to see a-ning have closed his eyes in concentration, tucking his lips in to avoid scraping with his teeth

“step three, roll your tongue”

a-ning does as he’s told, relaxing his throat to accommodate mo ran further, stroking the rest that can’t fit before curling his tongue, swirling it around the underside of his gege’s tip. flicking once, twice, inciting a moan from mo ran

mo ran immediately abandoned the phone after he told a-ning to also use his hands to play with his balls, bucking his hips up lightly when a-ning started bobbing his head

the lewd way a-ning’s reddened lips stretched around the girth of his dick had him losing control

he grabbed the back of a-ning’s hand, with his cock still resting against a-ning’s tongue, mo ran sits up to maneuver their position until a-ning is beneath him between his legs and mo ran is kneeling, supporting a-ning’s neck and head

by now a-ning had gotten used to the sheer size of mo ran and his throat had gone lax making it easier for mo ran to fuck his mouth. a-ning holds onto his thighs, looking at him in haze as mo ran cums down his bulging throat

a-ning, being the good boy he is, dutifully swallows all of him in bliss until he’s milked dry

the younger gives one last suck before mo ran pulls out, wiping off his cum on a-ning’s lower lip and kisses his forehead, telling him that he did a good job at satisfying his gege
