Experiment

It was a hot summer day. The sun was beaming down unconcernedly, heating up the students inside of IT’z Academy. Even though it was already 4 PM, there were still a few students around the school, either practicing for the upcoming competition or having discussions about the topic that was taught by the lecturer during the day.

The same goes for you who was sitting at a table in the library, waiting for someone to arrive. You got an assignment from your professor to give a presentation about the reproductive system and sexual intercourse. It was certainly a very awkward topic to be having discussions about, especially when your partner is a girl.

As you were focused on browsing your phone, you felt the presence of someone sitting down beside you. The smell of her floral fragrance filled the air, notifying you that your partner, Hwang Yeji, had arrived.

“Sorry that I’m late, got caught up by my roommate earlier.”

“Ahh, it’s fine. I just got here a couple minutes ago so I didn’t wait for too long.”

“Oh, alright then! Shall we…get started?”

You gulp nervously, this will be the first time you will be talking about sex with a literal girl. Nodding in agreement, Yeji grabbed her bag. She took out a few reference books, notepad and her cute mint colored pencil bag. Throughout all of that, you also took out some books and your laptop from your own bag while observing her silently.

Her outfit was definitely eye-catching, dressing up in a deep red long sleeved top with light blue jeans. With her dark, chestnut colored hair styled in high pigtails, her defined facial features stood out to you. Yeji realizes that you’ve been staring too long at her and waves her hand in front of your face. You snap out of your trance and laughed awkwardly while also apologizing for ‘daydreaming’.

The discussion starts with both of you choosing which subtopic each of you were going to present. Then, you boot up your laptop while Yeji starts to take notes from her reference books to put inside the slides. During the whole period, you were stuttering periodically, the awkwardness level between you both were increasing as the stuff that was discussed was getting even more…detailed. Furthermore, Yeji was having a eureka moment, looking fascinated at every single fact that she found in the book.

“So, women can lube up a man’s penis by using their mouth…I thought that they could just use lotions!” Yeji exclaimed.

“Y-Yeah, it’s called fellatio.” You said as you continue to work on the slides.

“I wonder how it would taste…” Yeji mumbled to herself.

“Sorry?”

“Uhh, nothing! L-Let’s continue.”

3 hours passed by in an instant, and you were getting a bit tired at this point. Now, Yeji was working on the slides while you search for more information in the books. Suddenly, she gets up from her seat and fixes up her shirt a little.

“I’m gonna find some more reference materials, wait here okay?” Yeji said and you nodded.

As Yeji left to go to the bookshelves, you took over the laptop to see what Yeji had worked on. In your head, you were only thinking about going home and what you should eat for dinner tonight. A few minutes later, you realize that Yeji has been gone for too long, but you just shrug it off since reference material, especially the ones about reproduction or sex in general are pretty hard to find. Worriness finally settles inside you as Yeji has been gone for almost 30 minutes.

Your gentleman self came out as you closed your laptop and started searching for her. You went through countless numbers of books and bookshelves, but still didn’t see any hints of Yeji. Thinking that more biology books were located on the third floor, you rushed up by the stairs, almost hitting a person on the way to hopefully find Yeji safe. Walking through more and more bookshelves, you eventually found yourself in a pretty secluded place where it was pretty far from the tables.

“Ahh, oppa…” Your ear caught a familiar voice.

You follow where it was emanating from, not caring about why the voice sounded a bit suspicious. Walking slowly while constantly turning your head left and right, you finally found Yeji who was leaning against one of the bookshelves. Because you could only see her shoulders and her hair, you walked closer to her. The sight that you were about to see was definitely unexpected, but a welcome one indeed.

Yeji was looking at a book with pictures of sex positions with her hand inside her jeans, closing her eyes and biting her lower lip harshly. She was constantly moaning your name silently and looking at the pictures for a vivid mental image before closing her eyes as you see her hand furiously moving under her jeans. You couldn’t believe it - She was touching herself in the library!

You stayed quiet, not knowing what to do. Your brain was filled with impure thoughts of what you wanted to do to her right now. The place was perfect, with no one around and dark enough until someone far away couldn’t see anything. After fighting with your own thoughts in your mind, you decided that it was enough. So, you came up to her front bravely.

“Ahh…Eh! Oppa-” Yeji was about to scream until your hand closed her mouth and putting a finger on your lips as a sign of keeping quiet.

“Looks like someone has been pretty naughty.” You said and slipped your hand into her jeans, making Yeji’s eyes widen.

Your fingers feel her pussy that was blocked by her teasing panties. The thin piece of cloth is already damp and warm, acknowledging that she’s turned on. Looking into her eyes, it was certain that she wanted this to happen as she looks at you with lust, practically begging for you to fuck her.

“Damn, you’re really wet. How about we… do an experiment right here?” Yeji nodded instantly, earning you a smirk.

You immediately pull down her jeans and her panties to reveal her dripping core. Yeji gasps as you release your hand from her mouth, finally witnessing a man that was about to eat her pussy out as you knelt down onto the floor. With your fingers, you teased her clit, collecting a bit of her juices to make you taste her. She was sweet, and you wanted more.

Licking your lips in lust-filled hunger with your tongue, it instantly latches onto her pussy, making Yeji moan slightly. She was barely able to cover her mouth with her hand, muffling her moans. You get to work by licking the outskirts of her lips first, then her sensitive clit, driving Yeji into euphoria. Your hands were also working by caressing her thighs gently while Yeji continued to leak for you.

Soon enough, you drive your tongue in a faster rhythm. The thrill of getting caught was something that you never thought would be so exciting. Yeji promptly grabbed onto your hair with her free hand while throwing her head back in pleasure. You moan gently because of the pain, producing a vibration on her pussy that made her squeal in delight.

Your hand suddenly slides over her crotch and assists your mouth to fill up her sensual level, fingering her wet pussy with two of your fingers. Yeji’s eyes rolled back and her body squirmed around in gratification. Even though the air conditioner was blasting its cold air, you both were starting to sweat as the both of you were too indulged in the course.

“Oppa, I’m-I’m g-gonna…” Yeji announced her arriving orgasm.

You had more plans for her, so you instantly stopped fingering and licking her pussy, earning a disappointed and whiny moan from her.

“Oppa! Why’d you sto-” You closed her mouth with your hand again after getting up.

“Don’t question it. You can only cum when I cum, which means-” You forcefully pushed her down on her knees and brought the prominent bulge of your crotch close to her face.

“…you have to suck my cock.”

Yeji looked up to you in awe - your dominance was one of the reasons why she was so turned on. Her hands then grabbed the hem of your pants and pulled it down alongside your boxers. Your freed cock slapped her in the face, making her flinch and giggle. Never in her life has she gotten slapped - let alone by a hard cock. She grasps it with her hand, shocked at how big you were as her mouth was opened the whole time.

“Oh my god…Will this fit inside of me oppa?” Yeji asked while slowly stroking your shaft.

“Ahh, j-just put it in your mouth already!” You demanded, making Yeji giggle because of how needy you were.

A few more strokes were made before Yeji plants a kiss on your tip and swirls her tongue on it. After being satisfied by the taste of your precum, she slaps your cock against her tongue, her eyes forming inverted crescents at you before finally putting it inside her warm mouth, instantly causing you to let out a silent moan. Her lips glide down your shaft with ease, her saliva coating your shaft fully as she moves her head back up.

Grabbing onto your thighs for support, she starts to suck you off with a slow pace. The pressure from the hollow walls of her mouth were driving you nuts as Yeji’s head bobbed up and down on your crotch. Her right hand massages your balls, widening your eyes as she skilfully stimulates you into extreme pleasure. As her pace increases in speed, so does the deepness of her mouth into your shaft.

When you promptly take a hold on the back of her head, Yeji gets a brilliant idea. She suddenly stops sucking you off, making you groan in frustration.

“Oppa, please fuck my face. I wanna taste your cum.” Yeji said as she strokes you gently while looking at you with her lust-filled bedroom eyes.

“With pleasure.”

You smirked as your hands moved itself onto the two ponytails that she had on her hair. It’s like she knew exactly what you wanted. She guides your cock into her mouth once again, leaving a few inches out for you to thrust into. Tightly gripping onto her hair, you began to move your hips back and forth, only inserting a few inches of your shaft so that Yeji could familiarize herself with your length.

When Yeji looked up to you to hint that you could go deeper, you were a little hesitant at first but seeing how needy Yeji’s eyes were, you couldn’t hold the gentleman act any longer. And so you thrust your shaft roughly into her, your tip reached the back of her throat, making Yeji gag loudly on your cock. You realize how loud it was, but you truly believe that there was no one around to see this act.

Your thighs were turning red due to Yeji’s painful grip on them, her fingernails leaving deep indentations on your skin. Both of you savored this moment fully, until suddenly your abdomen tightens, signaling your orgasm was about to arrive. You pound into her mouth faster, not caring how messy her face was getting and how loud her gagging was. Yeji also assisted on helping you to reach your peak by using her tongue to lick the underside of your penis as you continue to fuck her throat.

“I’m gonna cum down your throat baby. Make sure to take it all.” You said to her, replying with a simple ‘mmm’ on your cock.

Within a few seconds, you bury her head all the way down on the base of your cock as your tip bursted out your hot semen, filling her throat as Yeji struggles to keep it all in. Your head starts to feel dizzy due to the amount of dopamine that was released into your brain because of how big your orgasm was. Yeji starts to swallow down your cum as she realizes how much you were cumming to avoid staining the carpet floor.

As your orgasm subsides, you pull out your cock from her mouth with strings of her saliva following it. Yeji shows you her mouth that still kept an amount of your cum before gulping it down her throat, confirming to you that all of your load was in her stomach. She giggled adorably, finally getting a taste of your delicious cum.

“Thank you for the delicious meal, oppa.”
