'Nough done. Let's get started while I'm still running on the fuel called "lack of sleep". 

Tsukiya Tanaka lived alone. By day, he was a student. In the afternoon and evening, he was a construction worker. At night, he was a male brainwashed by lust. Monotonous lifestyle and lack of social communication with his peers beyond school led to an increased longing for another human being. However, he had no one to satisfy this desire. Tsukiya did not invite many people to his house as he would rather not receive pity for his living conditions. He lived in a fine apartment that was cleaned. He ate proper, homemade meals every other week. Living alone was fairly tough, but it was manageable if one put their mind to it.

There was a knock on the door. Outside the window showed nothing but the darkness of the sky. Reluctantly, Tsukiya forfeited his time in an imaginary world full of his carnal desires in order to answer the door. He was curious. Who would visit a person like him at a time like this?

"It's me. Open up."

Behind the door was Erika Airheart. She was one of the few people that Tsukiya could call as a friend, but the two of them tended to get into plenty of disagreements. 

"Geez, took you long enough," she exasperated. Tsukiya could only shrug in return as he retaliated, "Who the hell comes this late at night?"

"I do. Need any help with anything?"

"Huh? Let me see, everything is freaking clean since the last time you came in except for yesterday's laundry. Want to clean that?"

"...If you insist. D-d-don't get me wrong! I'm just doing it because you told me to."

"I was being sarcas-"

"I'll clean it!"

"Make up your mind damn it!"

The two squabbled on a bit before Erika relocated herself to the bathroom. Inside, there was a basket with a few articles of clothing from the day before. A certain odor seemed to linger on the clothes. When she reached out to put the clothes into the laundry machine, Erika could feel a sticky substance similar to slime or saliva with the exception of the thing being much thicker. Pondering about what it could be, Erika's face flushed with a deep shade of red and quickly threw the articles of clothing into the washing mechanism one after another. Upon grabbing the underwear, she paused slightly. Instinct seemed to dominate her actions as she brought it closer to her face. She sniffed and absorbed the male stench attached to it before dropping it into the purging device full of detergent and softener. After she completed her little quest, Erika skipped back out to the living room and encountered a depraved Tsukiya reading a magazine full of erotic models. 

"You're such a pervert." Erika could only sigh in disgust.

Tsukiya looked up from his magazine and protested. "It's a natural male instinct!"

"Pshh. You're just stupid. That's all."

"What?! It's the law of Mother Nature!"

"I'm saying that looking at that book is pointless.. when... you... have me."

"You? You'd beat the crap out of me if I touched you."

"Would I?" Erika's eyes glistened as they seemed to beg for an appropriate answer.

"Aww hell yeah you would 9 times out of 10." Tsukiya broke that expectation of hers.

"Well... What about the remaining 1/10?" Erika asked suggestively. She loomed over the prone Tsukiya who was on the couch. An impulse suddenly ran through Tsukiya as he reached out for the girl and embraced her with his arms around her waist. One pair of eyes met another as their lips inched closer to one another's. Tsukiya allowed his hand to slowly slide down the side of the person he thought as a friend only a few seconds ago. Erika felt her hand reach for the lower region of the male body and sensed the passion it seemed to emit. 

"Erika..."

"Tsukiya."

Just as the event was about to become something irreversible, there was a knock on the door. A somewhat frustrated Tsukiya released Erika and opened the door to address the person behind it.

"Onii-chan. Time is up." A blonde lolita girl told him.

"It's time to wake up isn't it?" Tsukiya questioned.

"Well, yeah."
