*Ding ding ding* The alarm set on the stage buzzes as everyone's attention moves to it. Twelve-noon sharp. The assistants in the room spring to their feet and call out for the next group of participants.
“Profesor Im Nayeon’s 12 o’clock please come forward!” One yells.
You hastily move from where you were and get through the small crowd to the assistant. You were quite literally shaking in your boots. You didn’t know what to wear, so you had on some business casual attire. Brown dress shoes, navy trousers, and a white button-up. You gulped down the last of your water from the small paper cup and crushed it before throwing it into the recycling bin on your way out.
“Please follow me.” The assistant said to you. It felt surreal, this didn’t have the same vibe as any other job or school interviews you’ve ever done before, you didn’t know what to expect. You didn’t even see the other students who were in the interviews before you left. The assistant walks you down the hallway and up the elevator to the 9th floor. You notice that in order to have access to that floor, a card key was used. He pressed his card against the reader and as it flashed green, he pressed the button. The button was even in the shape of a heart to emphasize that it was the Love Lab floor.
He leads you through the floor, a pinkish-red hue of LED strips dimly lights the hallways. You see some questionable things in some of the lab windows and think to ask, but keep it to yourself as you can feel the tension rising. Finally, you get to her office. Plastered on the door in big letters it reads, “PROFESSOR IM NAYEON - Love Lab no. 1” The assistant knocks on the door and waits for a response. He tells you to wait outside before entering. He goes in and exchanges a few words with Prof. Im before returning to the hallway and letting you in. “Good luck. She’s a tough one” He whispers to you.
You walk in to see that the room is also dimly lit with similar led lights. Her office is tidy and she’s sitting behind her desk. There’s a couch and a few bookshelves lining the walls. “Take a seat.” She scans over the paper in front of her. “Participant 021. We don’t use names here quite yet during this phase in order to keep a sense of… anonymity if you will.” You nod in response as you take a seat on the couch. “Since I’m your first interview, I’ll explain to you how this all goes down. Prepare yourself. If at any point you would like to stop, say the word ‘candy’. This will be for you to use in all of the interviews. If you choose to stop, your application will be terminated immediately and you will still be sworn to secrecy no matter what. These interviews are much different than any other type out there. As you know, this is the Love Lab. Many different things consist within the word Love, these interviews, or tests will show if you are able to fulfill those things, those needs. Does that make sense?” She squints her eyes and lowers her glasses to her bridge while looking at you. You nod and you get the feeling you know what she means.
She continues, “Each professor is known for a different study on Love, meaning to say different tasks and such that you and the other participants will need to pass in order to work for us. I see you’ve signed your consent form and you have passed the needed medical, fitness, and mental wellness exams. Your application was one of the only standouts we saw this year. Congratulations. We have high hopes for you number 021.” You feel a great sense of relief and proudness as you look down and give yourself a small smile. “Right, let’s not waste any time. Let’s begin.” You nod once again and watch as she gets up from her seat. You notice her legs are a little shaky when she stands. You wonder what happened in this room before you got there. She slides a bookshelf to the side revealing a small hidden room. It’s lined floor-to-ceiling with red plush. In the middle is a single chair. Along the walls, there are shelves and hooks, something straight out of 50 Shades of Grey, toys, and accessories galore, things you didn’t know the use of. In the middle of the room was a red bed in the shape of a heart with the headboard lining the top curved parts of the heart. Damn, they really keep a grip on the whole love thing. You thought to yourself.
Prof. Im takes a seat on the edge of the bed. You walk in and some sort of spark of bravery overcomes you for a moment. “What would you like me to do, Professor Im?” You ask.
“I want you to please me. Ruin me. Break me. You have 3 hours to do so. The last participant wasn’t so lucky, he barely made it through half of the time before I told him to get out of my sight. But you, I already like the look of you.” She scans you up and down before beginning to unbutton her shirt.
“I can use anything in here?” You ask looking around the room, starting to walk along the walls and examine things more closely.
“Yes, providing you know how to use it. I’m not asking you to kill me, I’m not an easy woman to please, you see. And I like things rough.” She winks and slightly nods towards the extensive wall of flogs, whips, paddles, and such. To be honest, you’ve only dabbled with BDSM mildly in your life, a few spanks here and there, maybe some tying up of the hands, but nothing like this. As your mind begins to drift into thinking of all of the possibilities, Prof. Im snaps you out of your haze. She stands up, now topless, and gestures for you to join her on the bed. You join her, sitting on the edge of the bed, and take your shirt off as well. She seems to admire you and your body for a moment before climbing on top of you.
She looks you in the eyes, hers are already filled with lust. Prof. Im crashes her lips onto yours. A steamy make-out session ensues, Quickly, your hands find themselves exploring her back and waist. Her hands knot up in your hair and you pull her harder against you, she gets the hint and starts grinding into you. It doesn’t take long for a large bulge to form in your pants. Your tongues fight for dominance and you moan at the skin-to-skin contact when your chests touch.
Remembering that this is still an interview and that you need to pass, you take your time, also noting the 3-hour time limit. You need to be able to keep the heat up for 3 hours, you can’t bore her or finish too soon. Somewhat meticulously, you plan out the next 3 hours, trying to focus on kissing her while noting your next moves. Your hands roam up and down her back before sliding your hand to the base of where her hairline meets the back of her neck, you yank her head back by her hair and move down to kiss and lick along the side of her neck. You earn a gasp and some light moans from Prof. Im.
“Mmm yes… remember… no marks” she reminds you and you nibble and kiss her neck.
Feeling the pressure build in your crotch, you hook your hands around her ass and under her thighs and quickly lift her up before spinning and tossing her lightly onto the bed. She gasps at your strength and confidence. “Eager are we? Already starting off better than the last participant” Prof Im smirks and bites her finger. “Now what’re you going to do to me?”
You kneel on the bed in front of her and hastily take off your belt. A move you admit you’ve done before, you grab her hands as she sits up and use the belt as makeshift handcuffs. “I’ll use this for now. I don’t want to waste my time going to grab the cuffs” You say nodding towards a far wall. “Mmm I like this” She purrs. As you finish quickly tying her up you hold her two hands above her head while your other hand undoes the button and zipper of your trousers before pulling out your hard length.
“Oh fuck.. So big..” Prof Im moans seeing your hard cock in front of her face, she licks her lips.
“Take it.” You demand, holding your cock, you bring it to her mouth, still holding her hands above her head, you take them and hold them against your chest. She understands, clawing her fingers into your chest as her head moves to the tip of your length. She parts her lips and you push in fully. She said she likes it rough anyways. Her eyes widen in shock and you feel immense pleasure as her throat takes your length down its tight wet walls. After staying still for a moment, you start to pull out and begin thrusting in and out of her mouth. She moans as you fuck her mouth, spit starting to drip down the corners of her lips. You pull out your cock fully as she sticks her tongue out and circles your tip with it. “Good isn’t it?” You ask her.
“Mhm.. I’m excited for the next few hours number 021.” She looks up at you.
For the first hour the two of you fuck like animals, you indulge yourself first eating her out and tasting her sweet juices and fucking in 3 or 4 different positions on the bed. The first stage of your plan was going smoothly. You had yet to use the various toys on the wall, but you glance at the clock every now and then to gauge your time. You’d plan to use those during the last 2 hours. The second hour for rough playtime, then treating the last as the final push to edge both of you until max capacity. You wanted to drive her crazy. Now understanding how the rest of these trials were going to go, you had to work up your stamina. In 3 hours you could probably finish twice, but your goal was to make her finish as much as you could, at least once per hour.
As the first hour was nearing its end, you decided to grab a toy. As Prof. Im, now untied, hair disheveled and body sweaty, lays on the bed recovering from your fierce pounding you get up and look at the wall of dildos. You choose one similar to your size and walk back to her. “Finally.. As much as I loved your cock pounding me I was wondering when you’d start making use of the stuff in here.” She says breathing heavily. “Oh trust me, I’m just getting started.” you respond.
You spread her legs and make your way between them. You bring the dildo to her mouth, “Suck it.” she does so making eye contact with you as she takes the toy down her throat before spitting on her hand and stroking the toy. You smile and take it down between her leg, moving it between her wet lower lips. She moans at the sight. You shove it into her and start pumping it before bringing your head down to eat her out at the same time. “Oh FUCK!” she moans, having 2 of the most pleasurable feelings at once. “Mmm fuck that feels so good”
Almost on instinct, she grabs her legs and holds them up and apart for you, wanting more. You bring your other hand up and grab onto her chest, playing with her nipple and massaging her tit. You simultaneously bring her pleasure and she starts getting close to the edge. “D-don’t stop… fuck yes oh my god” she moans, her hips now shaking and moving on their own accord to get more. Your spit mixed with her own juices make the toy easy to fuck her with and your mouth moves furiously on her clit. You can feel her start to tighten and push the toy, signalling her orgasm. You ramp it up thrusting harder and faster, sucking more on her clit and clawing at her tits. “I-I’m gonna c-cum!!” She yells out. You take your mouth off her for a moment, “Cum for me Professor Im… Cum all over me” One of her hands goes to grip your hair and push you back to her clit and holds you there before she yells out and her body spasms, her hole pushes the toy out and you continue to lick and suck her pussy as her juices flow.
You pull away once she releases your head. “How was that?” You ask smirking at your work, the sheets now even wetter, her chest heaving for air and your cock leaking precum. “Holy shit…” She says between breaths, “I might just already pass you.” You smile as you hear that. “We didn’t even get to use all these fun toys” You tease back, “And I haven’t even finished yet” You say looking down your cock, now pulsing with need to finish. “Usually I’m not this worn out so fast, but something about you…” She says looking at you up and down. “I’ll give you the next 30 minutes to make us both finish. If you do so, you pass.” she smirks.
“Challenge accepted.” You say catching your breath and wiping the sweat from your brow. “Have you done anal before Prof Im?” You ask shyly, not sure if it’s appropriate to ask. “Mmm.. once, but it took me a little bit to like it… I haven’t tried since… of course the last time I did it, he wasn’t as good as you.” You knew the sure fire way to make you both finish was her ass. The pristine tight starfish coupled with her dripping pussy.
You flip her onto her stomach and turn her around, so she’s facing the mirror on the opposite wall. You bring her up onto all fours before bending down to spread her cheeks and expose her tightest hole. You lick from her clit up to her starfish and dip your tongue in, she moans at the contact and she starts to loosen up. You dip from her ass into her pussy and back, stimulating both holes. You pull back and slide your index finger into her ass to allow her to adjust and she easily takes it in. You give her a few pumps before going back to licking and wetting it. You go back and forth like this for a few minutes until she's prepped. To get your length wet, you push it into her pussy and give her a few good strokes, she moans with every pass and clenches her walls onto it. “God, your cock feels so good in my pussy.” She moans. “Just wait until it fills your ass” You moan in return.
You do a few more thrusts into her pussy before your length is coated in her juices. You spit onto her tight hole one more time before you press your tip against it, “You ready? Let me know if you want me to stop” You tell her before you slowly ease your way in. “OH! Fuck oh my god yes.. Oh fuck its so full…” she moans out your length only half way in. You push more till your cock is sheathed in her ass, the whole process filled the room with a cacophony of her moans and yelps of pleasure at being completely filled. “It’s so fucking tight… it feels so good Professor Im”
‘“Oh for fucks sake.. Fuck me already and call me Nayeon” she demands. Your face fills with shock at this. But you can’t process it till later, right now you have a job to do. You start to thrust into her ass slowly, feeling her walls squeeze against your length already bringing you closer to the edge. You hold back and start to thrust faster, gripping into her hips. “Fuck Nayeon your ass feels so fucking good…” You moan, thrusting harder and faster into her, your balls slapping against her still wet pussy. Suddenly an idea pops into your head. You reach for the dildo on the bed next to you, “Should we try something new Nayeon?” You ask. “Mmm shit I don’t care I just need you to fuck me” She desperately says looking back at you through the mirror. You pull out of her ass and take the toy and slip it into her pussy, you hold it there with your hand and push your cock back into her ass. “OH FUCK” She yells out, now feeling truly filled. The pressure from the toy makes her ass even tighter and you moan out too.
You resume fucking her ass, now your balls slapping the base of the toy allowing it to slip in and out of her pussy at the same pace as you. “Oh- oh my god fuck… oh shit” Nayeon’s a mess in ecstacy. She’s never felt so much pleasure and so full before. You slap her ass then grab onto the back of her head and bring it up to look at the two of you in the mirror. “Cum with me Nayeon. Squirt all over me while I cum in your ass” You growl. She watches as you fuck her harder, her pussy now even wetter and pulsing harder squeezes the toy out and you bring a hand down to furiously rub at her clit. She squeezes her ass even harder on your cock. “I-I’m gonna cum Nayeon.. Fuck I’m gonna fill your ass…” You moan loudly, fucking her even harder and faster, your length moving in and out of her gripping hole.
“I-im cumming again!!” Nayeon moans, she falls forward as her body convulses in orgasmic pleasure and she squirts all over your balls and thighs, as her body tightens like an anaconda around your length until you reach your limit. You explode ropes of hot semen into her deepest parts, you grunt as you shallowly thrust into her, painting her walls. You both come down from your extreme orgasms and you pull out, you watch as she pushes your cum from her ass, you bring a finger to it and run it from her ass to her pussy, smearing your cum all over holes and clit.
“Oh my god..” Nayeon collapses onto the bed and you lay down next to her, your warm sweaty bodies tangled together. “You… pass” She says before her eyes close. You hold her in your arms as you too feel your eyes get heavier. You wake up to a jolt a bit later to Nayeon stirring awake, “Good morning” You say jokingly. “Mmm I haven’t passed out like that from a session in a long time” She says. “I think you’ll do just fine throughout these trials. I’ll be sure to let the other professors know.”
“Thank you.” you say getting up and grabbing a bottle of water while starting to get dressed. “So what next?” You ask as she does the same. “I see you have Professor Minatozaki next… You’ll have the session with her at 7pm so you have some time to clean up and rest before that. I suggest you rest up for her, I don’t think she’ll let up as easy as I did for you. Come back around 6:45 to check in. If you get past her, you’ll have Professor Myoi tomorrow and Professor Park the day after. Good luck number 021. I sure hope you make it through. I would like to see you again” Nayeon smirks before she pulls you in for another kiss and grabs at your now clothed crotch.
You exit the room and an assistant brings you out, handing you a reminder slip to come back at 6:45 and stamps your card “passed” next to Professor Im’s name. Now that you know what these trials are, you head back to your room to freshen up and get ready for Professor Minatozaki Sana.
