"Good, you deserve a little reward. Today, I'll let you experience just how incredibly pleasurable it feels to have wave after wave of climax."

Hela was also getting addicted to this training. She signaled for Luis to change positions, her smile utterly wicked.

"I can't take it anymore, Auntie..."

"Please spare Brook, this sensation... it's too overwhelming."

"No more... it feels so full, like I'm going to pee, Auntie, stop squeezing there..."

"Auntie..."

Inside the office, Brook's moans began to spill out, impossible to contain. For her, this erotic entanglement of unspoken rules was simply too intense.

At that moment, the sexy secretary's clothing was a complete joke. She lay on the desk, her hands cradling Hela's head, showing deference and not daring to push her away.

Hela was bent over her chest, sucking on her sensitive little nipples and kneading them with her hands, perfectly imitating Luis's actions.

Meanwhile, her nimble right hand traveled to where their bodies joined, parting the labia's protective folds to find an even more lethal zone, lightly pinching that exquisitely sensitive clit.

Her buttocks swayed, suspended in the air, while Luis stood behind her, gripping and spreading her beautiful black-stockinged legs, fully exposing her shameful pussy.

The man panted with rough excitement, his thick cock plunging again and again into the tender vagina, delivering a maddeningly wonderful pleasure that was more than enough to drive her insane.

The multi-pronged stimulation completely shattered Brook's sanity. Saliva dripped from her mouth, leaving her capable only of moaning, fucked well past the point of reason.

She had never imagined her own body could be so sensitive, nor had she ever dreamed that sex could be such a blissful experience.

Just as her third climax was about to crash over her, pushing her to the brink of madness, the man's cock inside her began to pulse violently. The glans swelled almost instantly, breaching the protective barrier of her cervix.

"Bitch... hurry, lick my asshole."

Luis's face was twisted, his eyes bloodshot, his hoarse voice crackling with a beast-in-heat intensity.

Hela smiled with soft seduction, obediently squatting behind Luis. She strained to part the hard muscles of the man's buttocks, and her soft little tongue darted forward without the slightest hesitation.

"No... I'm in my fertile window... don't cum inside... my husband always uses condoms."

"Haha, that makes it even better... too late. Feel it properly now."

The employee cafeteria of the First Municipal Hospital was open to the public. With the meal subsidies, everyone preferred to eat there.

The main draws were the clean environment, reasonable prices, and the especially wide variety of options. However, the medical staff were quite busy, most of them hurriedly getting their food to take back to their own departments.

"Hello, Director Hela!"

"Hello, Director Hela. You look particularly well today."

"Director Hela's earrings are so beautiful. Where did you buy them? I'd like to get a pair too."

Basking in the spring breeze of success, her ears were filled with flattering words. Every staff member passing by offered an obsequious, ingratiating greeting.

"You came down yourself? Secretary Brook must be busy again."

She returned each greeting, appearing very approachable and without any airs, but the look of triumph on Hela's face was impossible to hide.

Everyone was exceedingly attentive, acutely aware that this was the hospital's future number one. Even if they didn't seek to curry favor, they couldn't afford to offend her.

"Just looking around casually. Oh, her? She's still occupied."

Naturally, Kai's subordinates were all on edge, each worried about Hela settling scores later. Now was the time for Hela to appear benevolent, to reassure and appease them all.

She packed up three boxed lunches, thought for a moment, then added a few servings of nourishing stewed soup. Carrying it all herself, Hela returned to her office.

The door closed. The indecent scent inside the office hadn't yet dissipated. Luis was sprawled casually on her bed, still bare-assed.

His clean, soft penis lay limply as Luis contentedly smoked his post-coital cigarette, letting out a lewd chuckle.

"Put your pants on!"

Hela tossed the pants over. Glancing at the tightly shut bathroom door, she teased vulgarly, "So clean. Well? Satisfied with this sister-in-law?"

"Her technique still needs some polishing. You'll have to train her a lot more."

Luis couldn't help but laugh too. Having achieved his first creampie with a married woman, his sense of accomplishment had skyrocketed to unprecedented levels.

Brook was quite a delicate beauty, someone to be called 'sister-in-law,' a married woman. Combined with that secretary's professional attire, the allure was undeniably stunning.

Filling her up and then watching her weep silently, moaning through her climax, had excited the sinful pair for quite a while.

During the time Hela was gone, Luis had pressed Brook, who had rested briefly, down to his crotch. While the beautiful wife silently shed tears, he trained her, forcing her to use her mouth for post-coital cleanup for the very first time.

Though she was very uncomfortable and somewhat resistant, under Luis's training, she still swallowed the cum mixed with her own climax fluids.

"Her first time swallowing, right?"

"Likely. Very resistant, very clumsy. Next time, let's try a mouth pie."

"Next time, let's take her from behind. I want to see..."

"I felt her while you were fucking her earlier. Her asshole is very sensitive too, contracting fiercely."

"You're even more depraved than I am. Why'd you suddenly touch there?"

"Curiosity. When I was giving you that deep tongue bath, I even tried probing a few times. So tight, her husband must never have fucked it..."

The sinful pair discussed things brazenly. Brook in the bathroom could definitely hear. After the cascading climaxes, she was somewhat adrift too, but these vulgar words still made her burn with shame.

The office windows were left open, for ventilation and also because keeping the door shut for too long would look bad.

Most importantly, people would come by to seek instructions on work or seize a chance to get closer, so Hela couldn't just keep the door locked and act without restraint indefinitely.

Having cleaned up, Brook still looked radiant and full of charm. She sat to one side, eating her meal with a hint of shyness.

"No need to be nervous. You'll get used to it from now on."

Hela offered her unique brand of comfort, and then they naturally fell into conversation.
