Fireworks and Forbidden Glances
Clang! Clang! "...Huh?" Even the faintest sounds echoed loudly through the empty lecture hall. The noise came from somewhere far behind me, reverberating across the entire room.
"Hup!"
I wasn't the only one who heard it. Ayoung's eyes widened in surprise, a startled gasp escaping her lips.
Clang! Clang!
The sound kept repeating. Its source was obvious—someone was trying to open the iron door to the lecture hall. Good thing I'd locked it earlier. Otherwise, our secret tryst would have been interrupted.
But... why? Who would try to open the door to a darkened department building lecture hall on the third floor at this hour?
Soon, muffled voices drifted through.
"Oppa... is the door locked?"
"Huh? Yeah... weird. Lecture hall doors are usually left unlocked..."
One male voice, one female. They sounded like college students out enjoying the festival.
"Oppa, let's just go somewhere else. We can watch from another classroom. The fireworks are about to end."
"Ah... but this spot has the best view of the fireworks... Strange, isn't it...?"
Clang! Clang!
Their quiet conversation echoed through the lecture hall. Only after hearing it did I understand why they were trying to get in.
Whoosh~ Bang. Boom.
Behind Ayoung, a beautiful fireworks display lit up the night. They had come here looking for the perfect spot to watch the show. The guy had probably scouted this place earlier. Just as he said, the view of the university fireworks from the third-floor lecture hall was breathtaking.
But...
Slurp... Suck... Slurp... Suck... Slurp... Suck...
Perhaps it looked even more beautiful because I was watching it while buried inside Ayoung.
The moonlit windowsill. The dark, silent lecture hall. Beyond the glass, festival lights and tents stretched out below. Everything felt beautiful.
Especially Ayoung.
She kept her head bowed low, letting out soft sighs. Beneath her lovely face, her shirt and bra were pushed up, exposing her breasts. Her ribs showed clearly beneath her flawless skin. That almost-transparent complexion. Her smooth legs swaying rhythmically. And the traces of blood from her torn hymen still staining her thighs. All of it was beautiful.
Then, the voices returned, faint but clear.
"Oppa, hurry up and let's go over there. That door's open."
"Huh...? Wait... I think there's someone inside..."
"...Someone?"
Their voices faded. But I didn't hear them walking away either. They must have spotted us... and were watching.
The lecture hall door had a narrow rectangular window, just wide enough for a handspan, positioned at about head height. Perfect for peeking inside. I'd used it myself earlier to check if the room was empty before entering.
And now... another couple was peering through that same window at us.
Slurp... Suck... Slurp... Suck... Slurp... Suck...
"Haa... hah... haa... hah..."
"Hng...!"
Ayoung tried to hold back, but soft moans kept slipping out.
"Oh my... oh my..."
"Wow..."
The couple's surprised whispers reached us from the other side.
Whoosh~ Bang. Boom.
Neither we nor our hidden audience cared about the fireworks anymore.
Slurp... Suck... Slurp... Suck... Slurp... Suck...
The soft, tight squeeze of Ayoung's insides sent waves of pleasure through me. Part of me wanted to show off this incredible sensation to the couple beyond the door. What exactly were they seeing right now? My half-lowered pants and thrusting hips? Or Ayoung's legs spread wide on either side of me? What thoughts were running through their heads?
A strange curiosity kept bubbling up.
Then Ayoung, who had been still until now, suddenly moved. She leaned forward, burying her face against my chest.
Slurp... Suck... Slurp... Suck... Slurp... Suck...
"Haa... hah... haa..."
"Hng... hng... hng..."
We were so close I could hear her heartbeat. Her short hair swayed with every thrust of my hips. Her eyes shone with anxious light. Her lips were pressed tight. Her pale, delicate shoulders trembled. At this distance, every detail of Ayoung stood out vividly.
The reason she'd suddenly pressed herself against my chest was obvious—she was trying to hide her face from the couple watching through the window. She didn't want anyone else to see her expression.
Slurp... Suck... Slurp... Suck... Slurp... Suck...
"Haa... hah... haa..."
"Hng... hng... hng..."
My hips never stopped, driving my cock in and out of her. Ayoung clearly felt ashamed that someone else was watching us have sex in an empty classroom. But me? I found it strangely exciting. Like becoming an animal on display at a zoo. Half-dressed, fucking in the open—it felt primal, far removed from civilized life. And knowing someone was secretly watching me claim this beautiful girl only made it hotter.
Part of me wanted to show them her face. To let them see this stunning university girl being thoroughly taken by me.
Slurp... Suck... Slurp... Suck... Slurp... Suck...
"Hah... Ayoung... haa... lift your head... hah... so they can see... haa..."
"Hng...! N-no... hng...! I don't want to... hng...!"
"Hmm..."
Should I remind her again that I'd bought her? No need to go that far. But a little teasing sounded fun.
While still thrusting, I released one of her breasts and brought my fingers to her nipple. I pinched it lightly between my index and middle finger, then spoke to make her lips part.
Slurp... Suck... Slurp... Suck... Slurp... Suck...
"It's fine... hah... just once... lift your face... haa... Ayoung..."
"Hng...! No... don't... kyaaah!"
Ayoung suddenly cried out. The reason was simple—I'd twisted her nipple the moment her mouth opened. Her small, pink bud was now pinched tightly between my fingers. I'd done it on purpose so the couple at the door would hear her voice.
The more ashamed she felt, the more I enjoyed it.
Ayoung looked up at me with wide, embarrassed eyes. Tears welled at the corners from the pinch. Gazing down into those clear, innocent eyes... I pulled my cock out of her and pressed it against her lower belly, releasing everything.
Spurt.
"Kyaa!"
She gasped as the hot liquid splashed across her stomach.
"Haa... hah... haa..."
Rough breaths escaped me too as I finished.
Whoosh. Bang. Boom.
The festival fireworks were reaching their climax. Beyond Ayoung's shoulder, through the window, the sky exploded in longer, more brilliant bursts. Looking down, I saw another kind of fireworks spread across her belly—streaks of white cum glistening on her pale skin. I smiled in satisfaction. Just like the red fireworks that had bloomed on her thighs earlier, this white display on her stomach brought me pure pleasure.
"Haa... haa... haa..."
While catching my breath, I absentmindedly rubbed my cock against her belly, smearing the cum like ink on paper. Only this ink was thick and white. Before I knew it, both my shaft and her stomach were completely coated.
Then voices drifted from behind the door again.
"Oppa... touch me there..."
"What? Why not? It's mine, isn't it?"
"Pfft. No, oppa. Why would my body be yours...?"
"It is now..."
Whether it was from Ayoung's earlier moan when I twisted her nipple or the sight of my trembling back as I came, the couple watching us seemed aroused. From their conversation, the guy had started touching his girlfriend. She didn't sound entirely opposed, bantering with him playfully.
Then...
"Haa... hng... O-oppa..."
"Yeah?"
"Let's go to the next classroom. Not here in the hallway..."
"Alright. Let's go over there."
Once they got worked up, they moved to the neighboring room. Their footsteps faded, followed by—
Click.
Just like when Ayoung and I first entered, the iron door of the next classroom locked shut. They didn't want anyone interrupting them either. This campus building, meant for learning, had turned into a love hotel.
Once their voices disappeared completely, a small sigh left my lips.
"Whew..."
Whoosh. Bang. Boom.
My gaze returned to Ayoung. Beautiful fireworks bloomed behind her as she stared down at her own stomach, watching my cum slowly trickle down the curve of her belly.
Then the countdown timer appeared beside me, steadily decreasing.
[Remaining Time: 17 min 32 sec]
[Remaining Time: 17 min 31 sec]
[Remaining Time: 17 min 30 sec]
"When did it get this low...?"
No time to waste. I grabbed Ayoung's slender waist with both hands. That delicate curve always gave me a rush of pleasure whenever I held it. Savoring the sensation, I pulled her down from the windowsill and pressed her shoulders, guiding her lower.
"E-eh!? Juwan sunbae?"
She sank down until she was kneeling in front of me. I looked down. Her short hair swayed gently. One ear peeked out from the strands. And those clear, beautiful eyes gazed up at me—deep and lake-like.
Right in front of that lovely face, my cock stood rigid again. Covered in blood and cum, it looked almost grotesque. The contrast between Ayoung's beauty and my filthy shaft was striking.
Meeting her questioning gaze, I spoke.
"What are you waiting for? Suck it, Ayoung."
I ordered her to clean the red virgin blood from her pussy and the thick white cum from my cock with her tongue.
