Birthday blowjob||Namjoon

You and Namjoon were best friends that happened to live with each other, but you've recently been having wet dreams about him and one day you can't hold back anymore.
——-
Today is Namjoon's birthday but since he stayed up all night he was still asleep in his room.
You slowly open his door and peak your head in, your mouth goes dry at the sight.
Namjoon had kicked the covers to the edge of the bed, he was in nothing but boxers, and to make matters worse he was laying on his back with his arms behind his head.
You enter his room and close the door behind you, carefully sitting at the edge of the bed where the view of his bulge was visible.
You bit your lip as you leaned down and poked the squishy part.
You looked up to see that Namjoon hadn't responded to it so instead you licked him through his underwear.
That's when he let out a slight groan and moved around a little bit.
You gently pull down his boxers to reveal his semi hard member, you bit your lip in anticipation as your soft hands wrap around his girthy length.
You slowly pump his thick length, his face scrunched up tightly as light moans spilled from his lips.
Finally Namjoon's eyes flutter open and he looks at you with pure shock.
"Y-N nngh~ what are you doing."
He grabs your hand and gives you a confusing look, you slowly pull his hand away and take his whole length in your mouth causing him to let out a long groan.
"Y/N-"
You squeeze his meaty thigh, silently telling him to be quiet, you bob your head a couple more times before taking his member in your hand instead and smiling up at him.
"It's Mommy to you, baby boy."
You pull yourself up and straddle his waist, moving your panties to the side then sliding down his member quickly.
"Ahh~ baby you're so big!"
Without adjusting you start eagerly bouncing on Namjoon's dick as if there was no tomorrow. Namjoon held onto the sheets for dear life as he watched his cock easily disappear into your entrance, which only made him closer to his climax.
"Mmm~ Mommy! I want more."
Namjoon whines as he starts thrusting his hips into you and hitting your g spot.
"FUCK! NAMJOON BABY SLOW DOWN!"
At this point you didn't even feel in control as Namjoon had flipped you over and continued fucking the living shit out of you, you felt your climax near and Namjoon's now sloppy thrusts were giving away his nearing orgasm.
Namjoon thrusted as deep as he could as he came, the warm sensation made you cum as well with a small whine.
"Mm~ Happy birthday Namjoon."
"Thank you Mommy."
