Jongseob never saw himself as a Party guy he preferred staying inside or skating outside but when you asked if he would come with you to a party he just couldn’t resist.
Jongseob has liked reader for a long time since they have known eachother since middle school though reader seemed oblivious to all that was behind what she saw as „friendly gestures“ or as „Friendly personal gifts“
So as they went to the party jongseob seemed unsure but went anyway and as soom as he saw Keeho (The popular guy) Talking to Reader at the party and Theo, Jiung and Intak cheering him on. Keeho of course overflowing in attention spoke to reader „Hey are you single?“ reader looks at Keeho and nods „Yeah why?“.
Keeho smirked „Will you be mine?“ He said in an overly dramatic way holding a random flower which nobody knows where he pulled that from „Uh wow no thanks Mary poppins“ he groaned and whined „Why not your so hot we would be such a power couple!“.
„Being a power couple doesnt mean our personalities align Keeho“ she sighs and quickly shuts him down. Jongseob saw all this and when he met your eyes he didn’t look at you softly like he usually did he looked jealous? But why would he be jealous? You’re just friends? Right?
He walked over and grabbed your wrist dragging you away and Keeho yelled after you and Jongseob „Yo bro i was about to pull the huzz!“ Intak and Jiung both slapped his back at the same time and said „No you weren’t Keeho“ and Keeho yelped „I could have pulled that off…“
Jongseob looked at you and literally looked jealous and somehow betrayed? „Why would you talk to Keeho he gets a new girl every week! I mean he was flirting with you you don’t actually like him right?“
You smile „No i don’t and Keeho came up to me why?Are you jealous Seobbie?“ she jokes and Jongseob sighed and flushed „No well yes..“ you smirk „What do you mean no well yes you better use your words seobbie.“
He pulls himself together „I love you.“ you gasp surprised „Like in a sister way or-„ Jongseob cuts her off „No in an i love you as more than just friends way damn it.“ you flush red „Really? how long?“ he looks at you and holds your hand „Middle school..“
Your eyes widen „Really that long? and you hid it this whole time??“ He nods „You like guys like Keeho of course i wouldn’t tell you“ you scoff „Why would you think that?? I never told you what kind of guy i like? How would you know?!“ You scream at him.
„Why are you so worked up about it i mean you know now?“ Jongseob says and you groan „Jongseob i love you too!“ he looks at you softly „You do??“ you smile „Yeah and honestly seeing you jealous turned me on.“ she says as she locks the door and he grabbed you by your waist „Really?“ you nod and he begins kissing your neck you moan and he pushes you onto the bed.
You gasp and speak „You know i always thought you would be a sub.“ he smirks „Oh really huh?“ you nod and speak „How far do you wanna go?~“ he smirks „What do you think i mean your already wet aren’t you?“ your eyes widen „How do you know?“ his smirk grew wider „Lucky guess sweetheart“
„I bet Keeho keeos condoms here somewhere right?“ Jongseob frowns „Do we have to use one baby?“ you sigh „If you don’t wanna be a dad yet then yes we do Seob.“ he groans but but moves his hand to the drawer to find condoms anyways „You know i hate this right?“ you smirk „Cmon condoms are not that bad though..“ he frowns „It ruins the experience of feeling you.“
He finds the condom and pulls it out of the drawer „Okay this is a nasty amount of condoms i mean how many girls does this guy go through?“ You laugh „I don’t know but in another universe i might have been one of them“ he smiles „Okay i would love to talk about hypothetical stuff but you look to good right now sweetheart.“
„You smile do i now?“ he nods „Quit talking and enjoy .“ You laugh „Seob what?“ but as soon as he pulled down your pants and his lips connected to your pussy you let out a moan mixed with a gasp and he smirked into your pussy which made you audibly shake and he spoke „So needy huh?.“ He starts licking your pussy and you moan louder.
He shushes you and holds a hand over your mouth „As much as i love you and your whiney noises you need to be quiet cause we are still at a party in Keehos house.“ you nod and hold back your moans as best as you can but let little noises slip every once in awhile.
As soon as you feel your climax approaching he puts two fingers inside you and pumps in and out of you while still sucking your very sensitive clit and makes you cum. Then he unbuckled his pants and slowly pulls down his panties teasing you „Seobbie im horny please hurry up..“ he smirks at your request and pulls down his panties releasing his big twitching needy cock.
You gasp at the size and he laughs „Amazed sweetheart?“ as he teases your entrance „he groans and you let out a cry „Jongseob. Please just put it in..“ he smirks and nods slowly putting his dick into your entrance and stretching you out as you moan and he quickly covers your mouth „Shh sweetheart calm down.“
His words were making you wetter even though that felt impossible and he finally started moving in and out of you. You gasp and he holds your hand „Is it too big?“ he looks concerned and you smile „No Jongseob keep going..“ he complies and goes faster again after a you both came he pulled out and put the condom into a knot throwing into the trash.
„Do you think Keeho will notice?“ you laugh „As many girls as he brings in no i don’t think so.“ he laugsh with you and you put your clothes back on he hugs you from behind „Your mine now.“ You smile and look up at him „Always been.“
