You were crazy. That's what you thought while Namjoon was sitting on the floor, his back against the bookcase and you were sitting on his lap, with your legs on either side of his hip, rolling over his hard cock, trapped inside his pants.  It was three in the morning and you had just left a frat party where your friends challenged you two to have sex. This wasn’t such a difficult challenge, since you and he had been dating for over two years, and you hardly ever kept your hands away from each other, but as your friends adored stupid and complicated things, they challenged you to have sex in the university library.  As you were drunk and horny, you accepted the challenge and now it wasn’t long before you started to fulfill the bet.

"Fuck. I love how horny and dirty you get when you're high, baby." Namjoon whispered, gripping your hips and helping you move over him. "God, if you keep going like this, I'm going to get crazy."

"And what do you think that i want, love?" You whispered in his ear, making him shiver and tighten his fingers in your skin.

"I think that you want me to fuck you so hard that you'll scream my name so loud that everyone in this campus will hear how dirty my little slut are." He said holding your chin and making you look at him, smiling shortly after. Your eyes full of lust and desire confirmed his theories. "Let's start this party."

You stood up a little and he unbuttoned his pants, pushing it down. You were wearing a skirt, and Namjoon just pushed your panties aside, fitting into the entrance of your cunt and you slid over it, until his cock was all inside you.

"Damn, you're so wet, baby, do you like to ride on that dick? Huh? Do you like rubbing yourself on your boyfriend's cock? Damn, you're so delicious." Namjoon moaned, holding your breasts as you went up and down on his lap, holding him on his shoulders to lean on. You couldn’t control your mouth and moaned as low as you could, feeling Namjoon’s dick stretching your walls. When you didn’t answer, Namjoon grabbed your waist and started to make you move faster, causing his cock to hit you hard. You bit your lip hard, holding the urge to scream with the pleasure that was taking over your body. "Answer me, little bitch. You like it? Hm?"

“Yes, Joon."

"I knew it. My girl likes to be a bitch to me, don’t you?"

"I love being your bitch, baby" You moaned, louder than you should. You threw your head back and closed your eyes.

"Daddy." You moaned in a squeaky voice as Namjoon sucked at one of your breasts, and he grunted as he heard you say it. He loved it when you called him that. You didn’t care if you got caught by the security guard or the janitor, the only thing you wanted, that you both wanted, was to cum. And only you knew how Namjoon was good at making you come.

"Daddy ... Please"

"What do you want, baby? Tell Daddy."

"Eat me out, please Daddy. I need you tongue in my pussy."

A pretentious laugh came out of Namjoon's throat before he was gently laying you on the wooden floor, using his shirt as your pillow. Even though he liked being a little more rude during sex, Namjoon was always looking for a way to keep you comfortable. He kissed your lips gently before lowering his kisses down your chest and belly, until finally he was kissing your thighs, bringing his hot, wet lips to your thirsty clit. One of the things you loved about him, beyond his intelligence, kindness and beauty, was his ability with his tongue. He moved it in a way that made you see stars whenever he used it on you. You grabbed his hair, pulling it lightly, knowing he liked it when you did it.

"What the fuck ...!" He whispered, taking his tongue from you as he heard his cell vibrating. You took your fingers down to your clit and began to massage it while he answered the call. “What the hell, Seokjin… What?” He frowned. “Okay, give me a few more minutes ... Just a few minutes, Jin ... Yeah, I get it. Bye.” And so he stuffed the phone into his pants pocket and turned his attention back to you. “Jin said the security guard was coming to the library, and that he can give us a maximum of ten minutes before he gets here." Namjoon said as he knelt between your legs, resting his large hands on your knees, caressing it. “It's enough time to get dressed and run."

"I bet you make me cum in 5." You whispered, thrusting two fingers into your pussy. Namjoon's gaze dropped from your face and down to your cunt, his eyes darkened with desire. He let out a smooth laugh, looking back into your eyes, making the fire inside you burn even more.

"That's what you want, isn’t it? To be caught being a greedy little bitch, rolling on my dick.  Do you want the security guy to find out the greedy bitch you are?” He said holding your waist, making you sit down, then holding your chin and giving you a deep, warm kiss. "You want him to catch us, doll? Do you want him to see you cum on my dick? You want him to see the good bitch you're to Daddy?"

“Yeah” You answered, in a hoarse voice, and Namjoon bit your lip hard, making you whimper.

"Yes what?"

"Yes Daddy, I want it, please fuck me."

"Oh baby, don’t worry, I will fuck you. On your fours, now."

You obeyed. You spun on the floor and stayed on all fours for him. Namjoon wasted no time and pushed his cock hard into your pussy, making you pull the air so you didn’t scream. He began to thrust deep inside you, forcing you to bite your lips and squeeze your eyes so you wouldn’t moan, with the danger of the security guy already being around and listening. He knew what he was doing, he knew how to move, he knew where to hit you, he knew you as well as the palm of his hand.

"Come on, baby. Squeeze that hot little pussy around my dick." He groaned when he felt you begin to throb. You would cum in a few seconds. He then grabbed your arms, making you get on your knees as he hit you hard from behind. "Touch your little clit for me, baby.” He whispered in a hoarse voice, which made you roll your eyes with pleasure, unable to control yourself. You didn’t even have to masturbate to cum, because you were already cumming.

And Namjoon realized.

He used one hand to cover your mouth and the other to stimulate your clit and you took your hands back, holding his hip as he thrust into you, trying to the utmost not to moan, but when your orgasm reached the apex, you couldn’t stand it and shouted his name. Your moans coming out muffled by his hand in your mouth and tears falling from your eyes from the intensity of what you were feeling.

"Just a little more, baby. I'm cumming too ... fuck ... you're so tight, shit." He whispered with his face against your nape, kissing your skin as he used even more force in the thrusts, making you delirious. When he came, he let out a low, long moan, gasping against the back of your head, his chest ringing against your back, you both out of breath. “I love you, baby.” He said breathlessly, making you smile. You turned your head a little and gave him a light, calm kiss on the lips. But the moment was interrupted when you heard the library door being opened. You both widened your eyes and both lay on the floor, thanking mentally for being in the last corridor and consequently farther from the door.

You two looked at each other panic when you heard footsteps coming your way. Namjoon stood up pulling his pants up as you lowered your skirt and buttoned your blouse.

He was willing to fight anyone to give you a moment to flee, but luckily that wouldn’t be necessary, as the person approaching wasn’t a security, or a stranger, it was Seokjin. He looked at Namjoon, standing in a defensive pose, and then looked at you sitting on the ground, curled. Then he began to laugh and shook his head in disbelief.

"I can’t believe you actually did that."
