Oh god, oh god, oh god.
This wasn't just in front of strangers anymore; it was in front of her idol. Marin felt her body heat up again, her heart pounding against her ribs as if it were trying to burst out.
The full title of the game was Saint Slippery Academy: The Miraculous Life of a Shameless Young Lady in the Disgrace Club. The setting was an all-girls school where the male protagonist, the chairman's grandson, was enrolled and joined the "Disgrace Club."
In a normal light novel, a club with a name like that would be something boring like a service club—lewd name, wholesome activities. But Slippery Academy was a hardcore eroge. It sounded lewd because it was incredibly depraved, and all the girls in the club were the protagonist's slaves.
As an eroge, the club naturally had more than just the main heroine Shizuku as a route. It wasn't all solo CGs. Back in the convention hall, the mix of men and women had reminded Marin of the solo "public exhibition" CGs, but now, being stared at by Sajuna in the parking lot made her think of Shizuku's group-shaming CGs.
Bad, bad, bad.
Alarm bells rang in Marin's head. She could feel her inner thighs getting sticky. Yet, she couldn't stop her hands from sliding up the chain and cupping Rin Ito's hand.
"...?"
Rin looked at her with confusion. Marin guided his hand toward her lips and then... Ahn~
She took his index finger into her mouth, sealing her lips around the tip before sliding the whole finger in. Her tongue swirled around the digit, sucking and nibbling with wet, squelching sounds. Her eyes fluttered shut as she imagined his finger was something else entirely.
Gulp.
Sajuna, watching from the side, involuntarily swallowed. She was stunned. This fit the character Shizuku Kuroe perfectly, but this... this was way beyond the scope of mere cosplay!
Are they lovers? But the way she addresses him doesn't sound like it...
Before Sajuna could process the situation, her body suddenly stiffened. Her slender legs, hidden under her track pants, pressed together instinctively. She felt as if a finger had suddenly entered her own body, ruthlessly digging and prodding at a place she had never allowed to be touched.
Why is my imagination so vivid right now!? Just by watching, I'm getting wet... it feels like his hand is actually...
Sajuna might look small, but she was the same age as Marin. While she rarely read 18+ manga or played eroge, she wasn't a complete blank slate like Kaguya or Mashiro. She had "self-pleasured" before; she knew exactly what was happening to her body.
The hand holding her phone trembled so much she feared it would drop. Hold it together! If Marin finds out I'm creaming myself just by watching her, she'll be totally disillusioned!
He's looking at me! Stay calm!!!!
Sajuna kept her eyes glued to the phone screen, terrified of making eye contact with Rin. She wanted to cry. When did my body become this slutty? She gritted her teeth against the waves of pleasure and pressed the shutter button with a shaking finger.
Of course, Sajuna wasn't naturally that "sensitive." No matter how lewd a girl is, she doesn't feel a physical phantom limb just by watching someone else. The culprit, as always, was Kaede.
The moment Marin took Rin's finger into her mouth, Kaede's camera system had activated. Kaede was first surprised to see another "blonde" girl (Sajuna's hair was pinkish, but close enough in the system's eyes), and secondly surprised that Marin was bold enough to do this in a parking lot.
If she's going to be that bold, let's turn it up!
Kaede opened the System Mall and made a purchase: Sensory Link.
This system upgrade could temporarily link two parts of a person—like linking the mouth to the clitoris so that eating spicy food or sucking a finger felt like direct stimulation downstairs. But it could also link two different people.
Kaede had linked Marin's mouth directly to Sajuna's pussy.
Marin's horizontal lips became Sajuna's vertical ones. Marin's tongue became Sajuna's clitoris. Marin's oral cavity became Sajuna's vaginal canal. Marin's throat became the entrance to Sajuna's womb.
Currently, Rin's finger was only teasing Marin's tongue, but the sensation of being toyed with in such an intimate, forbidden place made Sajuna's knees buckle. She had no idea why she was feeling this; she just assumed she was a huge pervert.
Rin noticed Sajuna's strange behavior. He didn't know exactly what was happening, but he guessed Kaede was involved. No girl gets this affected just by watching. It clearly had something to do with Marin's mouth.
Rin glanced at Sajuna before focusing back on Marin. He decided to push it. He curled his index finger to pin down Marin's tongue, stretching her mouth open, and then slid his middle finger in alongside it.
"Ugh-nnh!!!!"
Sajuna let out a strange, high-pitched whimper and leaned heavily against a nearby car, her other hand gripping her phone with white knuckles.
Rin pretended not to hear. Marin's eyes were wide and she was incapable of speech as she took a second, then a third finger. Rin toyed with her tongue ruthlessly, his fingernails scraping the sensitive flesh and his pads pressing down as saliva squelched in her mouth.
Marin's gaze turned glassy. Even though her senses weren't linked, the thrill of cosplaying Shizuku and being "trained" in front of her idol was enough to make her leak onto the pavement. She was lost in her own world, unaware of Sajuna's plight.
Alright, that's enough for now.
Rin didn't want to risk a car owner returning. He pressed all three fingers together in the back of Marin's mouth and shoved...
"Gack!!!" "Eeeeiiiii!!!"
