A Daring Act in the School Bathroom
47. Freshman Kang Seo-yoon, Kim Mari
"Nice to meet you, freshmen. I'll be teaching this liberal arts class with all of you this semester."
It was only the second day since the semester started.
"Haa… Mari's really gotten bolder lately…"

Sitting in the lecture hall for a required liberal arts class, I found myself thinking back to what happened two days ago. Because we'd tried a position we didn't usually do, it felt way better than usual, and my rationality completely flew out the window. Neither of us was in our right mind. We had sex even more lewdly and stickily than usual, and things even escalated to the point where we started talking about trying plays we'd never done before.
"Hmm…"
"After graduating high school and just becoming college students, you'll all experience many new things from now on."
No matter how I thought about it, it seemed like neither of us could keep our heads straight after having sex… Back then, I wouldn't normally give a cleaning blowjob, but somehow it happened… 'Well, it wasn't exactly a bad experience, but' I never imagined she'd suggest doing it 'outside' instead of at home where it was just the two of us… Ah, maybe the memory of pulling out outside on the day her dick first grew was just that intense? Or was she just lacking stimulation lately? Sex was good, but doing it almost every day with the same person, it was inevitable we'd get used to it…
"Becoming an adult just happens naturally when you get older. It happens automatically. But being a 'grown-up' is different."
Honestly, I was a little interested too… To be honest, doing it outside was risky, but there was something thrilling about it, right? The pressure and tension of possibly getting caught by others gave it a thrill, so it was actually a fantasy for a lot of people.
"Now that you're adults, I won't be micromanaging you anymore, telling you to do this or that."
Still, if we were going to do it, I felt like we should prepare a bit in advance… If we got caught, it would be a huge deal. It would definitely get posted on the school community. We'd only just enrolled, so I really didn't want to get exposed like that already.
"You have to find what you want to do on your own and do it. Even if it's something you don't want to do, if it's necessary, you have to do it."
"First, I should look for a decent spot. I have plenty of time anyway, so maybe I can wander around after lunch…"
"If you just sit around expecting someone else to take care of you like when you were a kid, nothing will change. That's what this class is for. Take on challenges. Try something new."
Since it was the first class, we only did a light orientation before it ended. With some time left before the next class, I wandered around campus.
"Wow, this place is really huge."
Our high school was big because the foundation had money, but it really couldn't compare to an actual university. Thinking about properly commuting between major and liberal arts classes starting next year made me a little dizzy. Was there a shortcut inside the campus? Or a shuttle bus?
"Round trip takes about twenty minutes? Hmm, that might be cutting it close."
Walking it myself, the distance was farther than I'd thought. If I was lucky with the signals, the roads weren't congested, and I was in good condition to run, it was doable, but on the flip side, if even one of those conditions wasn't met, I'd have to sprint to the other side of campus the moment class ended.
"Haa…"
"What, why are you sighing? Something wrong?"
"Oh, you're here?"
Mari walked over with her hands in her pockets, apparently having just finished class too.
"No, I just checked out the campus round trip and it's bigger than I expected."
"Ah, yeah. I almost ended up late this morning too, you know?"
"On the first day?"
"If I hadn't left thirty minutes early on purpose, I would've definitely been late wandering around lost. Good thing I came out early."
"I guess the priority this week is wandering around campus and getting used to it."
"First, should we eat?"
"Ah, I heard from some seniors that there are a lot of good restaurants near the back gate."
"Ooh… But won't it be crowded since it's the start of the semester? Let's hurry!"
So that day, we rushed over and barely managed to eat lunch during our free period. Thirty minutes of waiting time, seriously.
* * *
Freshman life flew by in an instant. Everything was new, so it was all fun, novel, and enjoyable, which made time pass in a blur. It was now mid-March, when we'd gotten somewhat used to freshman life.
"…You really want to do it here?"
"You were tired yesterday and passed out right away, so we couldn't do it…!"
Looking like she'd reached her limit, Mari—her thighs bulging from how swollen she was—grabbed my hand and pulled me into the bathroom. It was a building somewhat far from the main building. It was quiet with few people passing by, so the chances of getting caught seemed low, but the tension was unavoidable anyway. With a thud, she closed the door and locked it, then pulled down her pants with trembling hands.
"Whoa… You were this hard?"
Her dick, erect to the point it was surprising her panties hadn't torn, sprang upward with a 'thwack.' Even though we'd only skipped one day, I could smell the thick scent of semen. Already in heat, Mari pulled her pants down to her ankles, completely took off her top and hung it on the door hook, then pulled her dick out of her panties.
"…♡"
With a soft plop, it landed on my face, and the rich smell of a futanari cock hit me hard. My nose went numb so I couldn't smell anything else, my ears felt muffled, and all my focus zeroed in on the monstrous dick in front of me. The veins bulging out made the already large, thick shaft look even more dangerous.
"Hnnngh…♡"

By the time I came to my senses, I was already pressing my nose against Mari's balls and breathing in deeply. The fishy, sticky smell felt like it was melting my brain. 'I can't resist this…♡'
I carefully opened my mouth and kissed the heavy balls filled with semen. When my lips touched with a soft smack, her dick twitched upward before falling back onto my head. It had a slightly heavy weight to it, but seeing the clear precum beading at the tip, I couldn't hold back anymore either. Any rationality telling me not to get caught by passersby or that we shouldn't do this in a bathroom had long since flown away.
"Seo-yoon, please."
Mari gently placed her hand on my head and stroked it while whispering softly.
"Yeah…♡"
With a 'haam,' I opened my mouth and started sucking on her balls first. Knowing how sensitive they were, I focused on stimulating them carefully so it wouldn't hurt.
"Haaah, Seo-yoon, where did you learn to do this?"
"…♡"
Fortunately, Mari seemed to be enjoying it, her hips trembling. When precum started dripping from the tip, I figured she was ready enough and stuck out my tongue to lick along the shaft toward the glans. When my tongue finally touched the urethral opening, the salty taste of precum spread throughout my mouth. At the same time, the smell of Mari that had been marinating all day filled my mouth.
"Hahp-♡"
"Hngh♡"
When I took the thick glans into my mouth, a gush of precum came out and I swallowed it down, then smiled and took her in deeper. Careful not to let my teeth touch, I focused on tasting the area behind the glans and the urethral opening. Especially when my tongue touched the frenulum connecting from under the urethral opening down the shaft, her dick swelled taut like she was about to cum before deflating again, repeating the cycle.
"Puhah…♡ Mari, you're so big…♡"
When I pulled it out of my mouth to breathe, the glans—now shiny and wet with my saliva and her precum—sparkled under the fluorescent lights.
"Huuu… Your mouth felt so good I almost came right there…"
"…Do you want to cum in my mouth?"
Mari shook her head at that.
"Not right now. Use your hand."
"Okay?"
When I carefully reached out and grabbed the shaft, I could feel the veins pulsing through my palm. Maybe because it'd just been in my mouth, it felt hot too. Schlick schlick schlick schlick— Not wanting to drag it out, I moved my hand as fast as possible. Mari squeezed her legs together and grabbed my shoulders.
"W-wait…! Too fast…♡"
"We have to finish before other people come. Come on, don't hold back. Cum."
"Ah, no…! Seo-yoon, wait just a second…!"
Mari begged while breathing roughly, but—
"No."
"…!"
"You want to cum, right? You look like you're about to cum right now. Don't hold it in. It's a bathroom anyway."
"Hnn, hnnngh…♡"
"You don't have to worry about cleanup. Look, there's a toilet."
"Kang Seo-yoon, you…♡"
Spurt—!!!!
Throb throb throb throb—!!!
Spurt, spuuurt—!
Unable to hold back any longer, Mari came hard, filling the toilet with thick, white semen. Her eyes went unfocused for a moment before refocusing. Her ejaculation far exceeded a normal amount, completely filling the toilet bowl with the smelly fluid. I squeezed out the last drops from her urethra with my hand, then pulled out some tissues to clean her up.
"How was it? Did it feel good?"
"…Next time, do it with your mouth."
"I'll do that at home."
"You'll do it later, right?"
"I'll think about it."
After flushing the toilet to erase all evidence, we walked out arm in arm like nothing had happened. While thinking about what to eat for dinner on the way back, I checked the school community and saw a notification for a newly registered HOT post.
"Huh, what is it?"
…It was a post with a title that bothered me quite a bit.
