Time for some smut brothers, remember that you can skip this one if you want.

While Ryona and Sayori's little hang out developed, the pink and purple couple continued their growing relationship.

Natsuki had some stuff to do with her father that day, so she told Yuri she would come over early the next day, which would be Saturday, and so the tsundere and the bookworm parted ways just like when they became friends.

Ever since that reward Natsuki gave her, Yuri's desire for her girlfriend had kept growing stronger and stronger every day. However, they hadn't done it since then.

Yuri was afraid to ask for it since this was something completely new to her. She knew very well she wanted it, at any time by now, but she didn't know what Natsuki wanted. Perhaps starting it herself was a bad idea and would just create an awkward situation if Natsuki didn't happen to be on the mood, or so Yuri thought.

Now that she had some time for herself, Yuri knew she needed to relieve some of that intense desire somehow.

Ever since that unforgettable first time Natsuki came over to her house, Yuri had kept the pen she had borrowed from her days before that. That time Natsuki had found the pen but luckily for Yuri, she didn't really get a closer look as she only glanced at Yuri's desk and saw it, telling Yuri to remind her to take it with her when she leaves. Due to the storm of events that happened that weekend, Yuri truly forgot to do so, and so Natsuki also forgot about the thing.

The stickiness of the pen had dried off a few days later when Yuri again found and realized she still had the pink haired girl's writting tool. Yuri was again thankful Natsuki forgot about it as she could've felt when it was still fresh if she would've touched it that day which would surely made her think the worst of Yuri, or so the shy one believed that day.

Ever since, Yuri had kept the pen inside one of the drawers of her desk and it was now time for it to see the light again.

Yuri locked her door as she arrived home and went upstairs immediately to get herself changed.

The purple haired girl took off her uniform and was now on her black bra and panties only. Yuri, already aware of what she was going to do, opened the drawer and decided to get over with it once and for all, she knew she would feel hot anyways so why bother putting on clothes at that point.

Yuri then took Natsuki's pen and laid down on her bed. She took a quick look at the small tool and smiled as she remembered the time she borrowed it from her girlfriend. As she kept remembering how Natsuki had that habit of putting the tip of the pen inside her mouth while she wasn't writing, which was the main fuel for Yuri's first use of it back in the day, she remembered how it actually felt having Natsuki's mouth somewhere else and so Yuri slowly slid the pen inside her panties.

Yuri rubbed the tip of the pen against her crotch gently and closed her eyes imagining it was Natsuki's tongue. She then moved downwards and placed the pen between her labia doing up and down moves, starting slow and going a little faster then.

The shy girl could feel her juices already starting to coat the pen as they poured outside her already wet insides only from thinking about the petite girl.

Yuri knew it was time and gently and slowly she inserted the writting tool inside her vagina and started rubbing it in circles against her wet walls while she kept thinking and remembering the feeling of Natsuki's tongue inside of her. Yuri started moaning quietly and rocked her hips against the pen that kept teasing her sensitive spots.

Natsuki was right in front of her apartments building when she received a text from her father.

Dad: I had to work extra hours today, I'm sorry, you can now go with your girlfriend though 😁

The short girl sighed slightly annoyed but nonetheless grateful since she was now able to go and spend the night with her lover, cuddling and maybe watching some anime just as she loved to do.

The pink haired girl thought of calling her girl to let her know she would be coming over after all but instead got a better idea and decided to give her a little surprise.

Despite Natsuki's refusal, Yuri had handed a copy of a set of keys of her house which included the front and back door, bathroom and Yuri's room. The bookworm had said it would be coming handy in case of any emergency and of course she trusted her girlfriend enough to make good use of it. Natsuki still a little hesitant at the time accepted and kept the keys always with her, adding them to her own set of keys.

Natsuki now in front of the purple haired beauty's fancy house, took a quick glance inside from one of the front windows. Yuri didn't seem to be downstairs so the pink one guessed she would be upstairs in her room, which would be perfect to startle her a little.

The petite girl then quietly unlocked the front door and locked it back, leaving her stuff nearby. Natsuki then with ninja like stealth, climbed upstairs and approached Yuri's room.

Just before slamming the door open as she had planned though, the shorter girl noticed a weird yet familiar sound coming from inside. Natsuki gently placed her ear on the door and listened closely.

The moaning sounds from her girlfriend was something Natsuki had present every night and day, so immediately, she gently opened the door and snuck her head inside to watch what was going on.

The sight was something Natsuki would never forget as Yuri was laying on her bed only in her bra with her eyes closed, the back of one of her hands on her mouth trying to silence the moans coming from her and the other holding something the size like a pencil that was inserted inside her pussy while her hips rocked against it.

Yuri seemed too focused as she didn't notice the girl sneaking inside her room now staring at her with crossed arms, quietly.

Eventually though, Yuri's eyes flutter a little and quickly noticed the highlighting pink color in front of her. Yuri then opened her eyes wide and quickly took the pen out of her vagina, trying to mutter something but really unable to string together any words while her face had become a red mass with purple hair.

Natsuki didn't say anything though and simply walked towards her, climbing on the bed like a cat and taking Yuri's wrist that tried to unconsciously hide the writting tool with one arm, making her reveal the object, Natsuki then took the still sticky and coated in Yuri's juices pen from her and moved it closer to her own mouth. The pink one then stuck out her tongue and rubbed it against the cilindric object wiping off the juices from it, tasting them and licking her lips every time she did so.

Once Natsuki was done licking the pen clean, while Yuri simply stared both turned on and surprised, the petite one then put the pen inside her mouth one more time and coated it in her saliva. She then moved closer to her girlfriend and gently shoved the writting tool back inside her still wet pussy.

Natsuki moved the pen back and forth inside her lovers vagina, letting her love juices mix with her saliva she used to lubricate the pen. While she did so, Yuri's aroused face stared at her with lustful violet eyes and moaned repeatedly. Natsuki then locked her lips with her girlfriends quickly pushing her tongue inside Yuri's mouth. Natsuki then wrapped her tongue against Yuri's to which the taller girl responded by doing the same while Natsuki continued pleasuring her with the pen she was using a few minutes ago.

The two pulled away from the kiss a few times, panting heavily to catch their breath with her mouths still connected by a thin string of saliva, with Yuri moaning into the kiss as the pleasure inside her pussy kept increasing.

When Natsuki instinctively felt her girlfriend was about to come, she pulled out the pen from her insides and put it aside. Yuri then looked at her with puzzled and pleading eyes, begging her to continue. Natsuki then got away from her lover a little, lifted her skirt and removed her panties while Yuri stared lustfully.

The petite girl then grabbed one of Yuri's long legs and rested it on her shoulder to then lock her own pussy with her girlfriends in what they called scissoring.

Yuri immediately felt Natsuki's juices pouring out from her vagina as she was already really wet just from kissing and pleasing her with the pen. The sensation was heavenly as Natsuki started rubbing her pussy against Yuri's own slowly, but soon quickening the pace as she started to moan too. Yuri answered rocking her hips against Natsuki's trying to keep up the pace while their juices mixed with each other's and the lips of their vaginas kissed.

Yuri continued moaning louder as the pleasure she was feeling was out of this world, not caring if the neighbors heard her at this point until she felt how it was all coming together and her fluids gushed out of her pussy scattering all over Natsuki's vagina and lower half zone in general.

Natsuki who thought was still able to hold on a bit longer felt her juices starting to gather inside of her as the sensation of Yuri's love juices pouring all over her crotch did the trick, making her come all over her lower half zone in response.

Both girls twitched and moaned loudly as they finish climaxing together, leaving their pussies connected for a little while.

The two then leaned forward and stared at each other with satisfaction in their eyes. Yuri smiled at her girlfriend and pressed her lips against hers softly sharing one more deep and passionate kiss with their lower lips still connected as well.

As they finally broke the kiss, Natsuki then moved her mouth to Yuri's ear and whispered, "Next time just ask, okay?". Yuri giggled and nodded, landing a quick kiss on her girlfriends cheek.

Natsuki then removed herself from Yuri's lower half after she felt she had regained some strength in her legs to stand up. "Come on, let's take a shower, I got all sweaty and sticky from scissoring you with my uniform still on", Natsuki said extending a hand to her girlfriend. "Alright love", Yuri chuckled and got up feeling her legs a little wobbly, but still hugged her girlfriend from behind as she made her way to the bathroom. "Yuri, my legs can't hold my weight and the weight of your big boobs right now", Natsuki said playfully, but still being honest. "Neither can't mine", Yuri said. "Hmph, stop boasting about it", Natsuki said pouting to which Yuri giggled happy.
