“Stand straight.” snarled Si-Jin in a whisper while he lay on her. Na-Yool tried to, but it was pointless.

“……kuuh…”

Still unable to raise her body up, she simply quivered again with excitement. Just then, the hot thing that was filling her unexpectedly grew bigger, ready to explode.

…How even could that disgusting thing still get bigger? While Na-Yool was inertly astonished at that fact, Si-Jin firmly grabbed her waist with his wet hand that was now done with the teasing, and lifted her body straight. For a brief moment, it gave her a new sense of security.

Si-jin, who had roughly pulled out, raised his waist and pushed back all the way again without any gap. Though the thrust was weak, the stimulation was excessively strong for her body that had just climaxed. The tip of his thick penis spread open her narrow walls and stabbed her deepest part.

“Ah-ang, ngh!”

At his every thrust, Na-Yool’s arms drifted dangerously, as if she was being swept away by the sea. Si-jin’s desk felt so wide and Na-Yool could not reach the edge even with her arms fully stretched. And so, with nothing to hold onto properly, Na-Yool started to instinctively escape by crawling forward.

But Si-Jin was not the kind to let her. As if to punish her for daring to run away, he slapped her ass with the hand that was in her mouth. Of course, this was all while he relentlessly kept pounding her as his other hand was lodged on her waist.

“Ah!”

He then strongly pulled her waist with both hands outside the desk and thrusted back hard. The sharp staccato sound of their skin slapping crackled through the air.

At the sensation of feeling penetrated all the way up to her throat, Na-Yool moaned, hardly breathing.

“Ha-uuuhng, hng…!”

“I can’t go deeper than this but…”

“Uuhng, haa……”

“It seems like you can’t take me all in backwards either.”

As he panted, his reproach fell on the back of her head. He muttered again as he slowly moved his waist,“Really, you’re damn too tight…”

“If you have – hnng – complaints, don’t rush in then, ha-hnn…”

“As if – ahh – you don’t take pleasure in. ah – sucking me in.”

“Ah, ah-aan, uh-ahng!”

“It comes off every time you squirt, so understand my frustration.”

“Uhuuhk…”

“As expected, is it because it’s too narrow down there?”

“To begin with. I am not – Ahh – tight. it is yours, that is, too – uhh – big. Until now, no one. has told me that – hnnn – I was. weird, uhaang…!”

Just as she was vehemently protesting, he shoved deep through. Rendered speechless, Na-Yool sobbed.

“If you are going to be stupid and talk about your fucking exes at such a timing, stop right there. Your hole would have made them go soft too.”

“Oh god, ‘hole’, how crude! Could you get any more vulgar! Damn…”

Nowadays, that naggy thought would cross her mind half-seriously and half as a formality every time Si-Jin would swear. Meanwhile, he would continue to either ignore her remarks about his swearing or respond to it like a dog in heat…

“So, it is yours, Mr. President, that is – hnn – weird!”

“Their small dicks are to blame.”

Pricked by his words, Na-Yool quietly shut her mouth for a moment. Although it did happen with a few of them ‒ but less than Si-Jin thought  ‒ , she never had a boyfriend with such a big one.

Were they… maybe half his size?

Her mind wandered off for the first time while she had sex with him. Her body bounced spiritless as she pensively recalled a few memories, when a menacing voice invaded her ear.

“It stood with just a glance from you, so can you imagine how surprised I am that my boy would let me down in your hole? If it goes limp, you’re on your own.”

“Uh-uhk, ngh… If it does, then – hnn – it can’t, it can’t be helped…”

“So it’s fine with you if we don’t reach the finish line?”

“Uhhng, hhnnng…! Hahng!”

“Hm? Are you okay with it?”

“……N-no…”

As soon as she answered, Si-Jin released her waist to grab and lift her flaccid butt cheeks and started to hammer hard. He then looked down at his work as if it was meant to happen.

“Hnn, hnng…”

Yes, he was enjoying the explicit sight of Na-Yool’s beautiful white ass wide open with her twitching flower-like back entrance in full view. And more than that, just below, the sight of his bulging penis frantically going back and forth stirring her insides.

The outside of the condom was smeared with her love juice. Si-Jin stared at it with much delight, but on the other hand, he looked irritated as he was still thirsty.
