Warining: There's smut
now that you're all warned let's start!
-------
Yerin : Mommy...I'm waiting for tonight...
I gripped her waist strongly and looked at her right in the eyes.
Y/n: You're doing it again right ? Just wait until we get home babygirl.
She smiles excited then nodded. I sat next to my group after meeting up with her and she went on stage. She did a sensual dance while looking at me right in the eyes. I gulped feeling myself needy for her body. She ended her performance and looked at me bitting her bottom lip.
Y/n: You'll regret it Jung Yerin...
I mumbled that to myself and they come over and I looked at Yerin with my eyes full of lust and she smirked. They sat next BTS and Yerin and V flirted. I saw them like that and anger came then I stood up knowing very well she winned her little game. We performed and I looked at her coldly while she smiled widely. We finished then went over to them and I looked at Yerin.
Yerin : I'll go to the bathroom quickly.
The others nodded and Yerin looked at me winking. We sat down and after some time I stood up and looked at them.
Y/n: I'm going to the bathroom.
They nodded and I went to the bathroom. When I entered I heard moans I knew very well. I oppened the door she was in and I saw her masturbating.
Y/n: Yerin.
She stopped then looked at me panting and a lustfull look.
Y/n: You deserve a little punishment.
I slammed the door and pinned her to the door roughly then took her chin strongly and she looked at me blushing.
Yerin : Do me more...
Y/n: Do you know how much I suffered seeing you dancing that way looking at me ? Or when you flirted with that guy ? Or when I came here just to hear you masturbate with the door open ?
She shook her head. I kissed her roughly and she moaned against my mouth.
Y/n: You really need a punishment for being a bad girl.
Yerin : Yeah...
Y/n: Turn around.
At this point my voice had authority in it. She turned around and I slapped her ass strongly making her moan.
Y/n: You like it right ?
She nodded panting. I took her hair pulling it and she moaned again.
Y/n: Answer me slut.
Yerin : I like it mommy...
Y/n: Louder.
I slapped her ass again.
Yerin : Ah...I like it mommy !
I smirked then I took off her dress and I slide my fingers painfully slow on her back.
Yerin : Mommy...please...
I took off her bra then pulled more her hair making her facing me.
Y/n: Please what ?
Yerin : I want to feel good...I wanna cum for you...
I chuckled then slapped her ass again, her ass was already red but I didn't mind knowing she liked it. I untied my necktie then I took her hands and tied them together.
Y/n: If you wanna cum you have to beg slut.
I grabbed her breasts and squeeze them strongly making her moan.
Yerin : Mommy !
I smirked then pinched her nipples and she moaned loudly. I turned her around then I sucked there making many hickeys and she moaned more and more.
Y/n: I didn't hear your beg yet slut. You better behave.
I pushed her against the door roughly and she moaned again.
Y/n: Now let's start shall we.
I turned her around again then took off her panties only to see the print of my hand on her ass better. I slapped it again stronger and she moaned louder. I kneeled in front of her wet pussy then I opened it and stick my tongue in her and she moaned loudly again.
Yerin : Oh fuck ! Mommy, it's so good !
I slapped her ass again and went faster, her walls tighten and I stopped then stood up.
Y/n: You like being a slut don't you ?
I pulled her hair again and she nodded moaning.
Yerin : Ah...yes, I love it mommy...
I looked at her then shook my head.
Y/n: Seems like you really like how I treat you. You like how rough I treat you huh ? Answer me bitch.
She moaned again when I slapped her ass.
Yerin : Ahh ! I love it mommy !
Y/n: Tss.
I entered my fingers in her and moved faster, she moaned again and rely on the door to not fall down.
Yerin : Oh god mommy ! I wanna cum please !!
Y/n: God has nothing to do with this you can be sure.
The sounds comming from her wet pussy made me want to treat her more badly.
Yerin : Oh fuck it ! Mommy, please let me cum ! I beg you !
I smirked and her walls became tight and I kept going but at the last minute I took off my fingers and she panted heavily holding the door to not fall on the ground.
Y/n: You better be ready bitch. I'm gonna make you cry more.
I saw the little tears that fell from her face but I liked it and she did too. I pulled her hair more and she came face to face with me.
Y/n: I'm always the one who win your little game.
She nodded with pleading eyes.
Y/n: Say it.
Yerin : I'm a badgirl and I didn't behave how Mommy wanted it. I started a game but I can't win it against you. I'm sorry Mommy, please make me cum...
I pulled down my shorts and panties and her face became excited feeling something rubbing against her red ass.
Yerin : You bring it...
Y/n: Yeah, I knew you were going to do that. Now tell me who do you belong to ?
Yerin : I belong to the one and only Kim Y/n, my Mommy.
Y/n: Good job slut.
I smirked then I entered her ass strongly and she moaned. I slapped her ass again and thrusted in faster pulling her hair everytime I went deep again. I went faster and then she came moaning loudly or more like screaming. Right after she came I entered her wet pussy and her legs trembled but I wrapped an arm around her body to help her stand up then I thrusted in her roughly and she screamed in pleasure.
Yerin : Mommy !! I'm gonna cum !! Ahhh !! Fuck !!!
She came again and I smiled then took it off of her. I cleaned it then pulled up my panties and shorts. I untied her hands and wrapped my arms around her.
Y/n: It's not the end but for now let's go back.
She nodded and I helped her dress up then we left the bathroom after fixing ourselves. I took her hand and kissed it.
Y/n: Yerin.
She looked at me and I kissed her softly.
Y/n: Love you babe.
She smiled blushing and nodded then kissed me too.
Yerin : Love you too Y/n.
We smiled then head to our groups.
