Professor Kim's Request

"Yes. If you grant me just one favor, I won't make an issue out of Cha Eunyung's matter."

"What... kind of favor?" Cha Eunju's eyes trembled. She was holding my left hand with both of hers. Her skin was especially pale because of her mixed heritage. Her breasts looked like G-cups, her waist was slender, and her hips were full and curvaceous. The white thighs peeking through the slit of her dress made me feel intoxicated by the mature allure radiating from her.

"I want to borrow your ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠body, Eunju."

"Y-Yes?" Her voice was flustered. "W-What do you mean by that...?"

"Exactly what I said. I want to borrow Cha Eunju's body."

"So... what exactly..." I set my phone down on the table. Then I gently placed my right hand over hers, which were still holding my left.

"Ah!" Cha Eunju flinched and tried to pull her hands away. I quickly reached out and grabbed her left hand. Her slender fingers rested in mine. A wedding ring gleamed on her ring finger. She tried to yank her hand free, but I held it tightly.

"L-Let go... Professor..."

"If I submit that video to the university steering committee, Cha Eunyung's life is over."

The phone on the table was still playing the video of Cha Eunyung's anal sex.

Strength drained from Cha Eunju's hands. Her voice grew weaker too.

"B-But still..."

"Even if something bad happens to Cha Eunyung, you'd be fine with that?" My tone was firm. No resistance remained in her grip.

"..." Cha Eunju fell silent, unable to say anything more. My hand slowly slid up from her left hand. Soon I was holding both of her shoulders. She only averted her gaze and offered no resistance. I stood up, pushing her down onto the sofa with my hands. Her eyes wavered.

"H-Here?"

"Yes." There was nowhere else to go. More importantly, quests could only be completed on campus. And... the thought of taking Cha Eunju in the same place I had taken Cha Eunyung strangely excited me.

Hoo... My body was starting to burn. I reached out and tried to push up her long dress, but her hands blocked me. I frowned slightly. To remind her of the situation, I brought up the video again.

"If the steering committee sees Cha Eunyung's video..."

"A c-condom." Cha Eunju looked at me and said the word. "You have to... wear a condom."

"..." I stayed silent for a moment. Then I applied more force, intending to simply pull off her panties. But Cha Eunju was resolute.

"If you don't use a condom... I absolutely won't allow it." Her expression was firmer than I'd expected.

Hoo... Her hands clutched mine tightly. Should I just force it? Several thoughts flashed through my mind. Then I stood up from the position where I had been covering her. When I rose, she also sat back up on the sofa. I walked over to Professor Kim Byung-yoon's desk—the same one where I'd found the lubricant last time. If it was his desk, there might be condoms.

-Rattle. -Rattle. -Rattle. I opened three of the four drawers but found no condoms. Only the lubricant bottle from before.

-Rattle. Hmm? In the fourth drawer, I found something unexpected. A small paper box the size of a palm. Printed on it were the words:

It was a contraceptive pill. I took it and headed to the small refrigerator beside the office entrance. Inside were bottled water and vitamin drinks for guests.

"Did you... find a condom?" Cha Eunju's trembling voice reached me. Somehow, it sounded like she almost wished I hadn't found one.

"..." I gave no answer. Instead, I quietly took out a bottle of water from the fridge. -Click. After closing the refrigerator, I walked back to the sofa where she sat and handed her the pill and the water.

"Eunju. This should do, right?" Cha Eunju didn't reply, her face full of displeasure. I drove the point home.

"If you don't like it, just leave. Just remember that whatever happens to Cha Eunyung will be entirely your responsibility."

"I... understand." She finally relented. Cha Eunju took the pill and water, placed the tablet in her mouth, took a sip, tilted her head back, and swallowed.

-Gulp. I watched her neck as she swallowed. The pale line of her throat, the hint of cleavage above her dress—my body grew hotter at the sight. The moment she set the pill and bottle down, I pushed her onto the sofa again.

"Aah!" She let out a startled cry. I slid my hand under her dress.

"N-No!" She grabbed my hand in panic. "..." When I met her eyes and applied silent pressure, the strength left her hands. My hand snaked beneath her dress like a serpent.

"Hng!" My fingers touched her sex, still covered by her panties. A flustered sound escaped Cha Eunju's lips. Ignoring it, I pulled her panties off. They slid down her plump thighs and caught on her right ankle. I lifted her right leg and hooked it over the armrest of the sofa, leaving her left leg dangling off the edge. Her panties hung from her right foot. Between her spread white thighs, her pubic hair came into view.

Once she was ready, I took the lubricant from my pocket as usual and unbuckled my belt, lowering my pants. Hoo... My cock, now revealed, was much larger than before. Thanks to the quest reward, its size had increased and its shape adjusted somewhat to match the partner.

100% compatibility, was it...? Unlike before, my shaft now had a slight curve to the side. After applying the lubricant, it almost didn't feel like my own. Veins bulged along the slightly curved length. It looked less like a penis and more like some other living creature.

I finished my preparations and slipped the lubricant back into my pocket. My fingers brushed against the spray can inside. Itch Spray. An item that caused intense itching wherever it was sprayed, and even the slightest touch would bring abnormal pleasure.

Hmm... I hesitated for a moment, then took it out. She might as well enjoy it too. I aimed the nozzle at her sex.

-Pssht. Pssht. Is this enough? I wasn't sure. It wasn't my first time using it, but I hadn't been able to check the effects immediately last time. More is better, right? I'll just spray plenty. Even a light spray was supposed to bring tremendous pleasure. With Cha Eunju's sex completely exposed and defenseless before me, I sprayed the itch spray generously over it.

-Pssht. Pssht. Pssht. Pssht. Pssht. Pssht. Pssht. I sprayed far more than necessary, yet no visible moisture appeared on her sex. It doesn't drip or anything. I didn't know why, but it didn't bother me. I put the spray away. Preparations were complete. Cha Eunju had been lying there with her legs spread, unable to do anything. I moved over her.

Hoo... Her white thighs spread wide. Skin like porcelain. And the black pubic hair nestled between them. I positioned myself above her on the sofa. I slid my left knee onto the cushion beneath her right leg while my right foot stayed on the floor. Once I was set, my cock came fully into Cha Eunju's view.

"Ah..." She seemed slightly startled by the sheer size of my swollen erection. It ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠looked like a small serpent raising its head.

-Slide. My cock slowly approached her sex. Eventually, the head of the little serpent pushed its way into the gap before it.

-Squelch. "Aahng!" Her eyes widened even more than when she had first seen my cock. She seemed shocked by the sensation of her sex being completely filled. Her hips bucked toward me for a moment, arching into a gentle curve that reminded me of a smooth archer's bow. I, too, felt a thrilling pleasure from my cock. Perhaps because it was larger now, the tightness felt intense. I could vividly sense every contour of her inner walls through my shaft. The pleasure from the very first thrust made me ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠move my hips with great anticipation for this session.

-Squish. Squish. Squish. Squish. My cock, which filled her sex completely, thrust in and out, scraping along her inner walls. The sticky lubricant created slick, obscene sounds between my shaft and her vaginal walls.

"Aahng!" Cha Eunju's lips parted slightly as a moan escaped. Just like when she swallowed the pill, she suddenly threw her head back. Her body trembled as the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠pleasure surged up from her lower half.

Her reaction... is intense. We'd only just started having sex, yet Cha Eunju was already losing herself beneath me. Her constantly writhing body was actually getting in the way. I sprayed too much of the spray. Spraying it indiscriminately had been a mistake. Cha Eunju's body seemed to be feeling pleasure dozens of times more intensely than usual. Next time I'll use it more moderately. Her moving body was interfering. I pressed down on her left shoulder with my right hand and her stomach with my left, pinning her in place. While I held her body steady, Cha Eunju looked at me with flustered eyes and spoke.

"P-Professor! Hngh! Just a moment... The feeling right now... haah! I-It feels... strange..." Before she could finish, I thrust my cock back into her sex.

-Squish. "Aahngh!" Overwhelmed by pleasure, she threw her head back again. In my line of sight, the pale line of her throat stretched out.
