Sae Niijima had been consistently coming home late, which was no shock to Makoto. Sae was a hard worker, and in a competitive field. It left little room for mistakes, and she always had to be the hardest worker in the room. Though unbeknownst to Makoto, the reason her sister was coming home late had little to do with her work. Though, Makoto did not mind it. She had a girlfriend of her own, luscious Ann Takamaki. The two enjoyed going on dates together, and with Sae gone, they always had some privacy. Makoto was studious just as she was in high school, she always had her hands full with work. A full 8 hours of sleep was a demand her body called for. She also was not easily awoken, Sae once had to wake her up when the fire alarm went off in the building– she slept right through it. Sae benefited from all of this, as she could bring home her girlfriend to have fun late at night without the judgment of her sister. Luckily tonight, Makoto was 'going out', not expected to return until the next morning. Which gave Sae Niijima a perfect excuse to have some fun with her girlfriend.

It was about 10 pm in Tokyo, Tae Takemi began to close up shop. She stood outside in the frigid cold, she was waiting for someone. Tapping her foot impatiently, Sae Niijima approached her from the shadows.

"About damn time!" she said in an angry tone. Sae only smiled at the woman, cupping her hand to her face. Quite out of character to everyone who knew her. Maybe that's why she hid her relationship from everyone.. She only wanted her girlfriend to see her in such context.

"You're cute when you're mad Tae-Tae" Sae booped Takemi's nose, her scowl turned softer as the display of affection. Her expression slowly changed into a smirk, she bit her lip knowing what came next. Sae bent in for a kiss, swooping Takemi off her feet. She giggled at her girlfriend's forwardness.

"You're lucky you're as attractive as you are Sae… If you weren't I'd be forced to take some drastic measures." Takemi spoke slyly, Sae could only continue holding her bridal style and kiss her more. "We should get out of here though. Your sister's friends hang out here, and no doubt they'd be interested in knowing about us", Sae nodded in agreement.

"Makoto isn't coming home tonight… So my place this time?" Sae asked as she slowly set Takemi back on her feet. The goth doctor nodded in agreement. The two headed down to Yongen Jaya station, holding hands. While holding hands was potentially the most mild form of intimacy, it still turned the two of them on. The train ride seemed to take forever, as the two women grew increasingly hornier as time passed. Sae was completely red in the face, just as her girlfriend was. Takemi placed their locked hands onto Sae's thigh, her smirk becoming more devious by the minute. Sae could feel her ears heating up at this small act of love.

When they arrived at the station, Takemi and Sae managed to keep it together long enough to get into the apartment. The two women knew they needed to be quiet as to not start a commotion with the neighbors. Takemi walked into the living room and placed herself onto the couch, sitting with her legs opened– the opposite of ladylike. Sae stood in the kitchen looking at her girlfriend, she was preparing a small snack for them to consume before things got heated.

"Sae… I'm in the mood to try something new." Sae looked up and saw her girlfriend straddling the couch.

"Oh? What might that be?" Sae smiled, knowing things would surely get fun.

"I've been watching a lot of… Well, sexual movies to give me ideas-"

"Tae, don't tell me you watched porn for the plot."

"Let me finish!" Takemi whined, Sae rolled her eyes and giggled a bit as she chopped up the melon.

"I-I just thought it may be hot if we were to do it in here…" Takemi became flustered, realizing her request would put the private nature of their relationship in jeopardy. Sae smirked a little, she put down the knife she was using to cut the melon.

"I mean.. As long as we're quiet. Makoto said she wouldn't be coming home tonight." Sae smiled as she looked at her girlfriend.

"Though I didn't think you were a fan of the act of possible Voyeurism, Tae" she giggled, Tae rolled her eyes at her girlfriend's joke.

"You like it too, dumbass." She said coldly, this turned Sae on even more. Usually she was the one talking to people in such a tone, but it being done to her in a context like this… There was something particularly erotic about it.

"Is it me, or is it getting hot in here?" Sae began to unbutton her shirt. She walked towards Takemi, who pulled Sae onto the couch.

"Feisty today, hmm?" Sae smiled at her girlfriend's sudden dominance. Tae didn't respond, instead, she flipped Sae so she would be underneath her. Sae's face turned bright red, Tae then began to kiss her. They were as quiet as they could be. While the two of them began making out, Sae began to remove Tae's shirt, leaving her only with her pants and her bra on. Sae grabbed her boobs instinctively, she began to work her way down to Tae's crotch. Tae let out a small giggle, as she moved her hand downward to Sae's crotch. Sae's breathing became heavy, she started sweating as the pure fervor of the moment became increasingly heated. Tae stuck her fingers into Sae's pants, attempting to begin to penetrate her with her fingers. Sae gasped, trying to keep quiet. Her pants fully came off at this point, only leaving her panties. Tae looked down and smiled at Sae, who was tightly in her grasp. She smiled seductively and bent in for a kiss.

"O-Ooh…. Tae, you really know how to please a woman…"

"Shhh. Don't talk, you'll wake up the neighbors."

"Not a chance."

"If you say so.."

"Shut up and do me damnit!" Sae yelled. Tae began to kiss Sae's neck, and finger her vagina. Sae began to moan, she began to take off her panties. Her panties were soaked as she had gotten very wet by the entire encounter. Takemi worked her lips downward, kissing all of Sae's body in the process. She then bent down on her knees and began to eat Sae out.

"A-Ah!" Sae moaned out, she no longer cared about if someone were to walk in. She was in a state of bliss and happiness. Tae continued to eat her out, even rubbing her clit intensely. Sae's breath became heavy and she started to hyperventilate. Tae knew she was about to climax, suddenly white fluid emerged from her vagina. It landed all on Tae's face. Sae gasped in embarrassment as she saw her girlfriend just take a face full of her ejaculate.

"I-I-I" Sae was frozen, but Tae smiled at Sae, in an attempt to let her know everything was alright. She moved her hand to her face, getting some of her cum on her fingers. She licked it. The two women were truly in ecstasy, they began to laugh quietly. This would soon be disturbed by the announcement coming from another person standing in the hallway.

"U-umm, sis?" Makoto stammered, suddenly, play time was over. "Fuck!" Sae audibly said. Sae looked up, hoping perhaps it was just her imagination. There stood Makoto, and behind her a Ann Takamaki, neither of them were wearing much clothing.

"I-it's not what it looks like!" Sae quivered as she spoke, Tae turned around to face the girls and attempted to cover herself up. Though, the cum on her face left little to the imagination as to what was going on.

"And what exactly does it look like?" Makoto said solemnly. Sae felt like her words were caught in her throat. She coughed a bit, trying to decipher how much Makoto and Ann saw. Sae began to dress herself and fix her hair as the two girls watched the older women flounder in panic.

"Well?" Makoto repeated herself. Sae didn't know what to say, this had been her worst fear.

"Weren't you staying out tonight?" Sae angrily stated, Makoto's face then turned to a scowl.

"Don't answer my question with another question. Answer me!"

Tae could see Sae's panic flowing from her face to throughout her body. She knew she needed to stop Makoto from questioning anymore. She wiped her face, hoping it wasn't clear what she and Sae had just done.

"You know, Sae. I think your sister would make a great public prosecutor." She smiled at Makoto, Makoto only seemed to harbor more rage at her backhanded compliment.

"Flattery will get you no where."Makoto coldly said, sounding ominously close to her sister. Ann then began to look concerned. It was clearly an uncomfortable situation, but there was no real reason for her to get so heated over a sexual moment between her sister and the death doctor of Yongen jaya. She began to also get frustrated, it was time to fire back.

"Takamaki, keep your woman in check." Tae said in a scolding tone, all three of the other women in the room eyes opened wide, as though they saw a ghost. Makoto turned pale at this, which seemed to halt her anger, for now ar least.

"Y-your woman?" Sae said quietly. Makoto then turned red.

"I-It's not what it sounds like!"

"Oh? Then what does it sound like?" Tae retorted, smirking at Makoto who was fuming with rage and conflicting embarrassment.

"See how ridiculous you sound? If you want to talk about things, lets talk about them like the adults we are." Makoto knew Tae was correct with her logic. She turned less angry very quickly, staring at the ground. Tae and Sae finished putting their clothes back on and sat at the kitchen table, where the half cut melon was. Ann and Makoto sat across from them, though they all seemed to be avoiding eye contact. Takemi was the only person who seemed completely unbothered by the entire encounter.

"Now then, Niijima-san. Care to explain why you and your girlfriend here aren't wearing many clothes?" Takemi questioned the two younger girls. Makoto got angry at her deduction, immediately retaliating.

"Are you really going to lecture me about being unclothed? You two were butt naked up until five minutes ago." Ann felt super uncomfortable, wanting to get out of that situation. She side eyed Makoto and grabbed a hold of her hand. Makoto's face softened a bit, realizing she had put Ann into an extremely awkward situation.

"Makoto, I…" Sae started to say, she paused nearly breaking into tears. Makoto shook her head in disbelief, she had lived with her sister her entire life! Never had she seen Sae Niijima react this way to any sort of situation. She realized that she must've been holding onto this secret for a long time, perhaps it was eating away at her. Regardless, her yelling certainly wasn't going to get the response she wanted from Sae. If anything, it would push her further away. Takemi recognized her girlfriend stuttering for words, she began to speak in her stead.

"Niijima-chan, we're sorry for keeping our relationship a secret for so long" Takemi explained, she held Sae's hand under the table. Sae began to cry, tears falling down her face. "I understand if you're upset with us, but do know we wanted to tell you… Sae-san tends to be reserved, she hated the idea of anyone knowing about us."

"And honestly…" Takemi smiled at her next words. Sae's eyes darted upward as if she were trying to deliver a psychic message to her girlfriend 'Tae Takemi, I swear to fucking god, if you say what I think you're about to say'...

"I have a kink for secret intimate relationships. The idea of having this big secret that only we know… It's sexy to me." Takemi explained, Sae's eyes calmed down. She mentally exhaled in relief, it was true that Sae herself had such a fetish, she just did not want Makoto to hear of what her sister found sexually appealing. Makoto was at a loss for words at this conjecture, she knew her sister was reserved and also deep down a people pleaser. Her rough prosecutor exterior was the Sae Niijima she showed to the world– the one Tae Takemi gets to see was a warmer, submissive type of person. Makoto's mouth was agape as she struggled to find words.

"I-I'm sorry you guys. I don't know why I got so upset…" Makoto admitted, her cold and angry attitude from earlier seemed to leave her face. Ann smiled at her girlfriend, she was so proud of her for not bringing out her 'FIST OF JUSTICE' metaphorically into the house. Takemi smiled back at the younger girl.

"It's okay Niijima-chan. Your anger is understandable." Sae wiped her eyes and looked around at her girlfriend, her sister and her sister's girlfriend.

"I, I uh… I suppose you and Takamaki are dating?" Sae asked kindly to her sister. Makoto turned bright pink in embarrassment.

"W-what gave you that idea?"

"Oh, Makoto. Give it up. We're literally in our underwear. What else could we have been doing before we walked in on them." Ann spoke up.

"There you go, Takamaki! Take charge of your woman!" she encouraged Ann, as it was clear Ann was the submissive partner in the relationship.

"Tae. Stop referring to my sister as "her woman"." Sae said in an annoyed tone, though she did find it quite amusing.

"I gotta say sis.. I never would've imagined you were a bottom." Makoto smirked at her sister. Sae's face turned bright red again and she began to cough, trying to divert attention from Makoto's embarrassing comment.

"I mean, as a prosecutor, I figured you'd want control of YOUR woman, you know?"

"Now, now, Niijima-chan. Let's not shame anyone for being a bottom. She's still your older sister, you know." Tae smiled at the girls across the table. Who would've thought the scary Sae Niijima didn't take the upperhand in the bedroom?
