A Day in the Life of a Sex-Slave Professor (2)

I sat her down on the toilet, spread her legs wide, and took a moment to admire the view. "It’s a lovely sight. You look just like a human toilet..."

"A, a human toilet...?"

I pulled out my cock, rested the head right against the entrance of her cunt, and leaned down to meet her eyes. "From now on, you’re my human ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠toilet. You’re going even lower than a mere sex-slave. You are my human toilet, Professor Song Eunchae."

Degrading her, I thrust my cock all the way in and began to move slowly. "Imagine it. Imagine yourself as nothing more than a human toilet..."

"Haa-euk... haa-eung... mmm..."

"If you make noises like that, you’ll get caught..."

"Hup... hup... hup..."

The tension of potentially being discovered by someone else, combined with the thrill of doing it in a public place, made her cunt clench around my cock with an intensity that was beyond words. I was enjoying that exquisite tightness, thrusting my hips faster, when—

We froze, my cock half-withdrawn, staring into each other's eyes. Her pupils were trembling wildly, and the way her cunt tightened even further around me showed just how terrified she was. The stranger, whoever he was, stood in front of a urinal. The sensor triggered, the sound of flushing water filled the air, followed by the sound of a zipper being lowered.

Upon hearing the man’s voice, Song Eunchae’s pupils dilated even further. The owner of that voice was none other than her boyfriend. Seeing that, I wanted to make her even more flustered, so I pushed my half-withdrawn cock all the way back in with a firm shove.

"Huuuup..."

She covered her mouth tightly with both hands, shaking her head from side to side, trying her best to suppress a scream. I didn't want to actually get caught either, so I didn't thrust; instead, I kept my cock buried deep, pressing, rubbing, and grinding the head against her cervix to keep stimulating her.

The sensation of her cervix being rubbed by my glans must have been overwhelming, as she shivered and sent me a desperate, pleading look. Her cunt was clenching around my cock so endlessly that I wondered if she even had a limit.

A moment later, the man finished his call, washed his hands, and left the bathroom. The door slammed shut with a heavy *thud*.

"Phew... haa... haa... What were you thinking? What if we’d been caught?"

"We didn't get caught, so what’s the problem? It was thrilling, wasn't it? Your cunt was clenching like a madwoman..."

With that, I began to thrust rapidly.

"Hup... hup... haa-hup... hup... hup..."

Due to the extreme tension and arousal, she was rapidly spiraling toward a climax. Just before she could finish, I pulled my cock out again.

"Haa... haa... Why again?... Please, just put it back in...!"

"That wouldn't be any fun, would it? That’s it for now. I’ll make it twice as good for you next time, so hold it in a little longer."

I helped her up, pulled up her panties, lowered her skirt, and straightened her clothes. She looked at me with a flushed face, biting her lip, her expression full of resentment.

"Haa... you’re really cruel."

"It was thrilling and fun, wasn't it? There’s not much time left, so do your best until the end."

"Haaa..."

I stroked her cheek as she let out a deep sigh, then stepped out first. After confirming the coast was clear, I signaled for her to follow. When I returned to my seat, the female bartender smiled and struck up a conversation again.

"You took a while. I thought you’d gone somewhere."

"Ah... I was on a phone call..."

I brushed it off and spent the time chatting with the bartender, who clearly wanted me to seduce her. After I’d had about three cocktails, Song Eunchae and her boyfriend got up to leave. About ten minutes after they disappeared, I said my goodbyes to the bartender and headed out.

I went to the hotel she’d mentioned and booked a room on the same floor. I showered, wrapped myself in a robe, and waited for about an hour... She contacted me sooner than I expected. Less than a minute after I’d messaged her my room number, there was a knock at the door.

— *Knock, knock, knock.*

When I opened the door, she entered and began stripping before the door had even fully closed. She must have been in such a rush that she hadn't even worn underwear, arriving in just a skirt and blouse. In an instant, she was naked, and she pulled at the belt of my robe.

"I’ve held it in for so long, so give me my reward quickly."

Demanding her reward, she frantically took my cock into her mouth and began to suck.

I’d been tormenting her all evening and stopping midway, and since I’d been holding back as well, my cock was swollen to the point of bursting. Once I was ready, I lifted her up, sat her on the edge of the bed, pushed her over, and lifted her legs like a frog to spread her wide. I stood at the foot of the bed, grabbed my cock, and slapped her clit.

"Haa... hoot... put it in already."

Since she’d been soaking wet and ready for ages, there was no need to make her wait any longer. I thrust my cock deep inside her.

"Haa-eung... this is it... finally... it’s here..."

She muttered to herself with an ecstatic expression.

"You’ve waited a long time, so now it’s reward time. Look forward to it."

"Ah-eung... heung... heung... hoot... heung... haa-oot..."

As the real thrusting began, I started moving my hips forcefully from the start. Perhaps because she’d been holding back for so long, she reached a climax almost immediately.

"Hang... ha, ha-ang... I... I think I’m going already..."

I thrust even harder as she was about to finish, twisting her nipples with one hand and rapidly rubbing her clit with the thumb of my other hand. "Haa-ang... heuaaaaaang..." She screamed as if the room were tearing apart and climaxed.

Her cunt was clenching violently, and while she was shivering and climaxing, I kept my cock buried inside and flipped her over into a doggy-style position. She was so out of it from her climax that even when I moved her around to get her into position, she just went limp and let me guide her.

I grabbed her pelvis tightly and began to move my hips again.

"W, wait a second... it’s still... so sensitive... let me rest for a moment... heuk..."

"I told you I’d give you a double reward. I’m going to make you come twice as hard."

"Haa... oot, eu-geuk... ha, ha-ang... please, gently..."

I ignored her pleas to rest and kept thrusting. Then, I lifted one of her legs while she was on all fours, putting her in a 'dog peeing' position, and kicked it into high gear.

"Huuuk... huuuk... I’m coming now..."

"Heu-ang... hang... euk... euk... I’m... I’m coming again... heuaaaaaang!!"

As I thrust like a madman, she climaxed once more, her cunt biting down hard on my cock. Feeling that pleasant tightness, I let out a satisfying load of semen.

At the same time as my ejaculation, she fell into her second climax, shooting out juices, her head buried in the bed, drooling, her entire body trembling. Her cunt was clenching so hard I almost couldn't pull my cock out. I gripped her pelvis and thrust my hips forward with all my might, enjoying the pressure of her walls tightening around me like a palm.

After enjoying the afterglow for a moment, I pressed her hips down so she was completely prone on the bed, and I climbed on top of her, keeping my pubic bone pressed against hers so my cock wouldn't slip out. I slid my arms under her armpits to grab her shoulders, supporting my upper body with my forearms, and applied a comfortable amount of weight onto her.

With her trapped in my embrace, unable to escape, I began to lift my hips and slam down again.

The sound ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠of my lower body colliding with her buttocks echoed through the hotel room.

"Heuk... again?... heu-ang... ugh... ugh... let me... rest for a bit..."

"I have no intention of letting you rest today. I’m going to gift you endless pleasure."

"Hang... ha-euk... p, please..."

The aftermath of the unfinished climax combined with my renewed thrusting forced her back up to the peak. The pain-like pleasure continued, and only after she had climaxed two more times did my second load of semen shoot into her womb. I’d ejaculated so much that it mixed with the previous load, spilling out from the sides even while my cock was still buried inside.

I felt a sense of satisfaction looking at her, eyes rolled back, tongue lolling out, drooling as she lay prone. I pulled my cock out and pushed it into her mouth. She automatically began to suck on it, looking so cute that I stroked her hair; even in her dazed state, she rubbed her head against my hand.

After she finished the 'cleanup' blowjob, I held her in my arms, stroking her breasts and waiting for her to come back to her senses. Come to think of it, although I’d had sex with her many times, this was the first time we’d done it completely naked. She had a tall, slim body, C-cup breasts that fit her frame perfectly, and while her hips weren't massive, her narrow waist made the lines leading down to her thighs and legs stand out beautifully.

She had a body beautiful enough ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to be coveted by anyone. The satisfaction of using such a woman as nothing more than a sex-slave was quite immense. I’d read her desires and obtained her so easily; she wouldn't be able to escape me in the future, either. Now that she knew this kind of pleasure...

As I was thinking this, she regained her senses and looked up at me.

"Are you coming back to your senses?"

"Yes..."

"How was it? Were you satisfied twice over?"

"Haa... I can't deny it. It was too good. Enough to drive me crazy. You were incredibly hateful at the sushi restaurant and the cocktail bar, though..."

It made me proud to hear that the customer was satisfied with the double service.

"Food tastes better when you're hungry, after all. But you came much faster than I thought. I expected it to take much longer..."

"Not every man is as energetic as you are."

She spoke in circles, unable to bring herself to say outright that her boyfriend was inadequate.

"Then you’re a blessed woman!"

"Yes?"

"You have a good job, talent, beauty, and you’re going to marry a decent boyfriend. And now, I’ll take care of the one thing you were lacking—physical satisfaction. You’ve become a woman who has everything, haven't you?"

"Ah... that’s not entirely wrong, either. Assuming I can just become shameless enough."

It seemed she still felt guilty toward her boyfriend. Well, that was to be expected of a normal woman.

"Can you escape from this pleasure?"

"......No, I don't think I can right now."

In the end, she admitted it. That she couldn't escape this pleasure on her own...

"Then you have to be shameless. For your own sake."

"Haa... I suppose I have to, don't I?"

"Yes. That’s the only way you can be happy."

We finished our conversation, showered together, and after I filled her womb with semen one last time, I sent her home. I decided to ignore the fact that her legs were trembling as she walked away.
