Chapter Text
jackson and mark had always been open about their feelings for bambam, and vice versa. they became friends originally in middle school, before the two eldest started dating. bambam had not yet presented, so although they knew the thai shared the same feelings that they felt for him, neither jackson nor mark wanted to add him to their relationship until he had presented. they didn’t want to risk anything, and bambam understood that.
after talking it out and agreeing, they waited, a long four years (since the start of mark and jackson’s relationship), for bambam to reach that maturity and the couple wouldn’t feel guilty, as if they were taking advantage of him. most pups presented by the time they were sixteen - bambam was still unpresented at eighteen.
so once bambam frantically texts the groupchat babbling about how he’s definitely presenting, seemingly as an omega, the two elders were shocked. “seun-ah,” mark breathes, staring down at the phone screen with bambam’s text displayed, “bammie’s presenting,”
“let’s go,” jackson immediately says, already standing up from their spot on the bed. mark grabs him by the back of his shirt, pulling him back down on the bed.
“no way,” mark intervines, standing up himself. “you’re an alpha, he’s presenting as an omega - your instincts would kick in, and we both know how vulnerable and dangerous it is the first time!”
jackson pouts, but sinks back into the sofa in agreement.
“will you go, then? i don’t want him to be alone,” he huffs, and mark nods, already slipping on his sneakers.
“i’ll take care of him. he’s probably in pre-heat now.” mark states, running a hand through his hair. “i love you, gaga,”
“i love you too, markie-poo.” jackson replies, cupping mark’s face when the older leans down to peck his lips.

mark pulls open the door after he successfully enters the combination lock for bambam’s apartment, having memorized it long ago when the thai impulsively told the combination to the two older men.
“bam-ah?” he calls out, swallowing the lump in his throat as the unfamilar aroma of cinnamon and vanilla fills his senses instead of bambam’s usual milky scent. mark guesses that he’s going to have to get used to the thai’s new smell, now that he’s finally presenting.
“hyung,” he hears a small voice say with the thai accent that he’s grown to love so much, and when mark flips on the entry-way light, bambam’s gasping and helplessly shoving his face into mark’s shoulder, clad in only one of jackson’s tshirts that nearly reaches mid-thigh, brown hair sticking to his forehead with sweat. “too... bright. too hot, please.”
the older quickly turns the light off, wrapping one arm around bambam’s shoulders, and the latter whimpers. mark decides that he made the right choice in demanding jackson stay back at home. if he didn’t have such strong self control as a beta, mark wouldn’t be able to control himself.
“hyung, please -“ bambam starts, voice barely above a whisper, when mark interrupts him with a hush.
“bambam,” mark breathes, lifting the younger up who immediately complies and wraps his legs around the american’s hips. “seunnie isn’t here, but mark hyung is here. hyung will take care of you, okay? he’ll make sure you drink enough water and eat enough,”
“hyungie,” bambam practically whines. mark realizes that he’s definitely too far gone. “hyungie can... can hyung... knot me?”
for a second, mark swears his heart physically stops beating. he shakes himself out of his trance, and carries bambam towards his bedroom, where he can be far more comfortable. mark’s glad he payed attention in high school health classes, otherwise he would have no idea what to do.
“hyung’s won’t knot you, sweetheart.” mark sighs, and bambam draws out a whine. “not this time, at least. hyungs want it to be special, wanna make sure everything is safe this time,” he adds and sits on the younger’s bed, bambam placed in his lap.
”can... hyung still - still help?” he pouts, skin glistening with sweat or slick or a combination of both. mark decides - who would he be to deny him?
-
“does this mean i get to be you guys’ boyfriend, now?” bambam asks, two days after his first heat ended. voice muffled by where he has his face buried into jacksons chest.
“yeah,” jackson hums, not bothering to try and hide the grin finding its way to his face.
“finally ours.” mark adds, stroking jackson’s nape as he presses a kiss to the top of the youngest’s head, bambam being sandwiched between the two. home has never felt more sweet.
