The weekend.
On the day of the group shoot, Rin Ito and Orie, just like last time, picked up their luggage early in the morning to first collect Sajuna and Shinju before heading over to Marin's house together.
To save time, they had already styled and prepped their wigs at home beforehand, so arriving here only required simple makeup before they could head to the studio together, change into their clothes, and immediately start shooting; although the schedule wasn't as tight as a convention, the rented studio had a strict time limit, so they still needed to prepare early.
Visiting Marin's house for the very first time, Sajuna and Shinju were utterly shocked the moment they stepped through the door... the sheer degeneracy of the otaku room was far too dense.
Explicit, R18 dakimakura pillows and posters were everywhere, and the display cabinets were packed with various lewd, erotic figures of Shizuku... What made it even harder for Sajuna to keep a straight face was the otaku shirt Marin was wearing, which was printed completely with Shizuku's ahegao face...
This was the kind of sight that made Sajuna cringe so hard her toes wanted to drill straight through the floor.
Seeing the two sisters' astonished expressions, Marin proudly puffed out her chest to show off Shizuku's ahegao face.
"How about it? Pretty awesome, right?"
"Your house really is..." The corners of Sajuna's mouth twitched, swallowing the second half of her sentence. "It's getting late, let's start on the makeup."
"Please wait a moment!" Orie stopped Sajuna just as she was about to start her makeup, pushing up her glasses with her index finger; if this were a manga, Rin Ito would absolutely draw a close-up panel of her glasses gleaming with a lens flare.
"Sajuna-chan, your lingerie is completely finished. Why don't you use this perfect opportunity to try it on and see how it fits?"
"Yeah, exactly, since you're already here, you might as well try it on first. If a cosplay costume has minor flaws you can still force it on, but if something is wrong with your lingerie, it'll be pure torture," Rin Ito said with a smile. "Conveniently, I also provided quite a few reference opinions for this specific lingerie set."
Orie rarely crafted wholesome, child-friendly magical girl outfits; as a condition for agreeing to tailor a magical girl cosplay for Sajuna, Sajuna had agreed to wear custom lingerie made by Orie beneath the costume.
"That's right, Ito-sensei gave me a mountain of advice and even sketched some reference diagrams for me." Orie's glasses practically gleamed with excitement; tailoring lingerie for Sajuna's flat-chested body type served as a completely novel experience for her.
Most of the lingerie Orie usually crafted was based on adult doujinshi designs and tailored to her own voluptuous figure, but she had never made lingerie suited for an absolute flat board like Sajuna before, so she had asked Rin Ito and Eriri for reference advice.
Rin Ito provided insights from a male perspective, while Eriri provided advice from a flat-chest perspective.
In fact, Orie had also prepared a set for Shinju to wear, but because Shinju had previously stated she wanted to keep it a total secret from Sajuna to give her a massive surprise, Orie only brought Sajuna's lingerie along today.
"N-No way! At least not right now!"
Sajuna's cheeks flushed crimson; if it were any ordinary day, she wouldn't care too much, as she had already shared wild sex parties with Marin, and Orie was a woman too, so it wasn't a big deal.
But it was completely out of the question right now!!!! Absolutely not right now!
Sajuna glared viciously at Rin Ito... he knew perfectly well what state her body was in right now, yet he still expected her to change her lingerie right in front of them!
Unlike Ichika before, who didn't want her sisters to see her wearing a chastity belt, Rin Ito had already allowed Sajuna to take off her chastity belt during her exam week.
But well...
Just because the chastity belt was gone didn't mean there weren't other things inside her.
Currently, a long string of smooth, perfectly round anal beads was packed deep inside Sajuna's ass; Rin Ito had specifically tasked Shinju with shoving them up her backside before they came over, and after inserting them, Shinju had even snapped explicit photos to send to Rin Ito. Each bead was slightly smaller than an egg, and after undergoing his intense training during this period, Sajuna's rear was fully capable of accommodating Rin Ito's massive cock, so squeezing a string of toys inside was an absolute breeze.
Rin Ito leaned close to Sajuna's ear, dropping his voice to a whisper.
"Only a tiny pull-ring is left hanging on the outside. If you clamp your cheeks tight, no one will notice~ You wouldn't want to disappoint Shinju, right?"
"...You bastard." Sajuna's lips trembled, stealing a glance at the immensely expectant Shinju beside her. Since it was the price for getting her cosplay outfit, she would have to wear it sooner or later... and it was exactly as he said, she had to face it eventually.
"Fine, then..."
Although Sajuna had a dark, thoroughly displeased look on her face, she reluctantly agreed.
"Please wait a moment!" Orie excitedly bent over to open her suitcase. "Ito-sensei can step into the adjacent room for a second while she— wait, eh?"
Before Orie could even finish her sentence, Sajuna took a deep breath and stood completely straight.
Exactly like what that perverted bastard Rin Ito had told her, only the small loop meant for pulling the beads out was left on the outside of her ass; as long as she clenched her butt cheeks hard, she shouldn't expose her secret.
Without thinking too much, Sajuna directly stripped off her trench coat, giving Orie a massive shock; Orie had originally intended to ask Rin Ito to wait in the other room so Sajuna could try on the lingerie here, but she never expected Sajuna to strip completely naked right in front of Rin Ito's face.
Although Orie had participated in Mashiro's reference orgy parties before, she had only ever gone as far as lounging around in her own underwear... she had absolutely no idea about the intimate sexual relationship between Rin Ito and Sajuna's group.
Sajuna stripping down so casually startled Orie completely, leaving her momentarily at an absolute loss for words.
"What are you standing around dazed for? Take it out and let Sajuna try it on..." Rin Ito's words brought Orie back to her senses; if Sajuna herself didn't mind, why should she be embarrassed?
Stripping off her trench coat and jacket, Sajuna revealed her cute underwear printed with a strawberry pattern... though rather than lingerie, it was more like a flat camisole top, since given Sajuna's flat board chest size, she didn't even have a use for an actual bra.
Since Sajuna didn't care, Orie didn't say anything further either, pulling out a lingerie set that was as thin as a cicada's wing; the semi-transparent black lace was even thinner than typical stockings.
Aside from two narrow patches of fabric, the rest consisted entirely of slender strings; while it was called lingerie, it offered absolutely zero coverage for her privacy, its sole purpose being to maximize Rin Ito's sexual arousal.
It was bad enough that the fabric was incredibly scarce, and bad enough that it was completely semi-transparent, but what caught Sajuna's attention the most was—why the hell were there two little holes right on the nipples of the bra!?
"Come on, let's get started." Rin Ito pressed his hand against Sajuna's shoulder to untie the strings of her camisole, while Shinju squatted down in front of her older sister to pull the cute underwear down.
Shinju grasped the fabric on both sides with her hands and gently pulled downward, but the crotch section seemed completely stuck to her flesh; only as Shinju's fingers worked further down did the clinging fabric slowly peel back.
Her delicate pink slit parted slightly, leaving a faint, glistening trail of wet juices across the pure white fabric of her panties; fortunately, Rin Ito hadn't turned on any vibrations during their journey here, so Sajuna was only slightly turned on. Squatting down to look closely, it wasn't overly obvious, looking merely a bit exceptionally wet and plump.
Shinju suppressed a giggle, quickly rolling the panties into a ball to hide her sister's wet secret, while Sajuna's earlobes turned completely scalding red, her clenched fists pinned tightly against the outsides of her thighs, her petite, rigid body standing completely straight as if she were a soldier on guard duty.
Oblivious to the truth, Marin and Orie simply assumed Sajuna was being incredibly shy, but in reality, Sajuna was standing at strict attention solely to clench her butt cheeks tightly together, preventing the pull-ring crammed inside her ass crack from slipping out.
Marin's eyes stared intently at her, her brows knit tightly together as if she were pondering something deep; just as Sajuna began to panic, wondering if Marin had caught onto her secret, Marin slowly opened her mouth.
"Juju-sama's stomach looks a little bloated. Have you gained a bit of weight recently?"
