summary: you love making changbin feel good and his birthday gives you the perfect excuse to spoil him
you wake up before the sun fully rises on changbin’s birthday, the early morning light barely filtering through the curtains. he’s still asleep beside you, his broad chest rising and falling in a steady rhythm that you’re sure will make you fall asleep if you stare at him for too long.
you slip out of bed quietly and go to the kitchen to prepare his favourite breakfast, although you have something much more special planned for him. when you return to your bedroom, you see he’s finally awake, a grin adorning his face as soon as he sees you.
“happy birthday, babe”, you say, setting the tray on the nightstand as you crawl onto the bed and then him.
changbin’s eyes darken as he takes in your barely covered body, because the only thing you’re wearing is one of his t-shirts that barely covers your ass. his hands immediately find your thighs, squeezing the soft flesh there with possessive hunger.
“thank you, baby”, he says, his voice still rough with sleep, but then he smirks, “are you going to give me my present now?”
you pretend to think and then lean in close, letting the t-shirt ride up just enough to flash the curve of your ass.
“what do you think it is?”, you murmur against his ear, your breath hot on his skin.
his fingers tighten on your thighs, “i don’t know, you tell me”
you shake your head, a wicked smile playing on your lips. instead of taking the t-shirt off, you sit back on your heels and let your hands trail slowly down your own body, tracing the outline of your breasts through the fabric. your nipples are already hard, poking against the material. changbin’s gaze follows every movement, his tongue darting out to wet his lips at the same time you feel him hardening beneath you.
“please”, he says, his voice already strained, “i want to see you”
you tilt your head as your fingers play with the hem of the t-shirt, lifting it an inch higher before letting it fall back down, “you want me to take this off?”
“fuck, yes”, he groans, his hands sliding up to grip your waist, “take it off. let me see you, please”
you lean forward again, pressing your chest against his as you whisper, “beg for it, birthday boy”
his hips shift beneath you, and you can feel his cock even harder now, “p-please, baby. it’s my birthday”
you sit up and slowly, teasingly, pull the t-shirt up inch by inch. first your stomach is revealed, and then the underside of your breasts. changbin’s breathing grows heavier with each exposed inch but you pause just before your nipples show, watching his face.
“more”, he says, his voice hoarse as he begs you, “please, i-i need to see all of you”
finally, you pull his t-shirt over your head and toss it aside, revealing your naked body completely. his cock twitches beneath the sheets and you move so you can peel the covers back slowly, exposing his cock, and the sight makes your mouth water.
you wrap your fingers around his cock, stroking him and making him groan as his hips lift off the bed. you lean down and run your tongue along the underside of his cock, from base to tip, tasting the salt of his skin and the precum already there. your tongue traces every vein as you savour the way he trembles beneath your touch.
“f-fuck, baby”, he moans as you take him into your mouth.
your lips stretch around his cock as you sink down, taking as much of him as you can. your hand works what doesn’t fit in your mouth, twisting and stroking as you bob your head. you can feel him growing harder against your tongue, the head of his cock hitting the back of your throat.
his fingers tangle in your hair as you hollow your cheeks to suck him harder, your tongue swirling around the tip each time you pull up. saliva drips down his cock as you take him deeper, relaxing your throat until your nose presses against his pelvis. he curses, his thighs tensing beneath your hands and you hold him there for a moment before pulling back, gasping for air, strings of spit connecting your lips to his cock.
“come here”, he growls, reaching for you, but you just shake your head.
“mmhm”, you say as you shake your head, “it’s your birthday. let me take care of you, my love”, you tell him.
you move to straddle his hips, positioning yourself above his cock. you rub your wet cunt along his cock, coating him in your arousal. your slick folds glide over his cock, the tip catching on your clit with each pass. his hands grip your waist and his fingers dig into your skin.
you reach between your bodies and line him up with your entrance. slowly, you sink down, taking him as the stretch burns inside you as your cunt opens around his cock. his head falls back against the pillows, his mouth open as the moans come out. when he’s fully buried inside you, you pause, adjusting to his size. you clench around him making him groan and then, you place your hands on his chest to help you move.
you start riding him, rolling your hips in circles before lifting up and slamming back down. each time you sink down, you can feel him hitting that spot inside you that makes you tremble. his hands roam your body, squeezing your breasts and pinching your nipples, before they move to grip your ass hard enough to leave marks.
“that’s it, baby”, he says, his voice strained, “f-fuck, you feel so good”
you start moving faster, bouncing on his cock even harder. your breasts bounce with each movement and changbin can’t look away, he doesn’t want to. the muscles in your legs strain as you lift and drop, taking him deeper with each thrust.
he sits up suddenly, wrapping his arms around you, and then he starts thrusting up into you as you grind down. his mouth finds your neck, sucking marks into your skin, and one of his hands slides between your bodies to rub your clit.
“come for me”, he says against your throat, “come on my cock, baby”
the combination of his cock hitting deep inside you and his fingers on your clit pushes you over the edge. your orgasm crashes through you, your cunt clenching and pulsing around his cock. you cry out his name, your body shaking as waves of pleasure wash over you and your juices coat his cock as you come.
but even then, changbin doesn’t stop. he flips you onto your back without pulling out, taking control. he pounds into you hard and fast, chasing his own release, his hips snapping against yours.
“come now, babe”, you say as you pull him closer to you, “come for me, birthday boy”
he buries himself deep as he comes, his cock pulsing as he empties inside you. you can feel every spurt of his hot cum filling your cunt, the warmth spreading through your core and when he finishes, he collapses on top of you, both of you panting and sweaty.
after a moment, he rolls off you but keeps you close as his hand moves to stroke your hair gently.
“i can already tell this is going to be the best birthday ever”, he says, making you laugh as he presses a kiss to your forehead.
you smile against his chest, already thinking about round two. after all, it’s his birthday and you have all day to make him feel good.
