"Gack!!!" "Eeeeiiiii!!!"
The sensation of fingers invading the throat made Marin's eyes bulge. If she hadn't had experience giving blowjobs, she would have gagged or vomited.
But Sajuna had it much worse. Because of the sensory link, Marin's throat was linked to the deepest part of her cervix. Being touched there was something that only happened in Eriri's hardcore doujinshi.
But the system link made it even more intense than any manga. First, there was no pain—only pure, overwhelming stimulation. Rin's fingers were in Marin's mouth, not actually tearing through Sajuna's body, so there was no limit to the intensity. Second, the dexterity of human fingers was something a toy could never match.
It was too much for a virgin like Sajuna, who had never even held a boy's hand besides her father or grandfather. She dropped her phone, her legs giving out completely as she slumped to the ground. Her pink eyes rolled back into her head, and a thin trail of drool leaked from her lips.
A second later, her body arched. The fabric of her tracksuit pants and the ground beneath her turned dark as she let out a massive, uncontrollable spray of urine, losing consciousness instantly.
"Holy shit..."
Rin and Kaede were both stunned by the extreme reaction. Kaede quickly cut the link. Rin pulled his fingers from Marin's mouth and caught the unconscious Sajuna.
Ignoring the fact that her pants were soaked with piss and girl-cum, he scooped her up. Marin's "pet play" was a minor scandal; Sajuna being found like this in a parking lot would result in a police report.
Ai opened the car door. Marin, shaking off her daze, rushed to help.
Rin wanted to check her vitals, but Marin blocked him. "We'll handle it in here!"
"I've had first aid training," Ai added firmly. "You'll only get in the way... unless you just want an excuse to see a helpless girl naked?"
"Fine." Rin stepped back and contacted his "System Daughter."
Rin: [Can you check her? Is she sick? What the hell did Kaede do?]
[Don't worry, Daddy. Her vitals are fine. She just suffered a massive sensory overload and passed out. She just needs rest.]
Rin exhaled in relief. [What exactly did Kaede buy?]
[Mommy linked Sajuna and Marin's senses. Basically, when you shoved your fingers down Marin's throat, Sajuna felt like you were fisting her womb.]
"Jesus..." Rin hissed. Even a girl like Karen would probably pass out from that. If he had known, he wouldn't have played so rough.
A while later, Sajuna slowly woke up. She saw an unfamiliar car ceiling and three silhouettes.
"Where am I..."
"You're awake? You're a boy now."
Marin's voice made Sajuna freeze. A boy? A BOY!?
"Eh? EEEEEEHHH!?" She sat up abruptly. Looking down, she saw she was wearing a loose butler's uniform. With her flat chest... Did I really change gender!?
No. Her brain cleared, and memories of the parking lot flooded back. She had climaxed so hard she passed out just from watching them. And she had... she had pissed herself.
Her brain throbbed with shame. She wanted to die. She wanted to pass out again and wake up on a street corner somewhere. But Marin was right there, clearly holding back a laugh.
"Relax, you're still a girl. I helped you change."
Marin was the only one in the car with her. Rin and Ai had gone back into the con to find Kaguya and Sagiri, leaving Marin to wait. It was for the best; if Sajuna had seen Rin the moment she woke up, she might have committed suicide from the embarrassment.
"You fainted so suddenly... I thought you were sick. I didn't realize your body was so... slutty."
Marin had been worried at first, but when she stripped Sajuna's pants off and saw the swollen, pulsing clitoris and the drenched thighs, she knew Sajuna had been right there with her.
"Do you secretly like lewd stuff like Slippery Academy, Juju-sama?"
"I'm not that slutty! I..." Sajuna tried to defend herself, but she had no explanation. She had never felt anything that intense before. Am I actually a depraved girl?
"Compared to me... you're the lewd one, Marin! Sucking his fingers like that... it's shameless!"
"It's not shameless; it's the ultimate love for Shizuku!" Marin's eyes grew fervent. "Shizuku is so cute! She's cold at first, but once she's trained and shows those helpless expressions, it's amazing. I love her so much I wanted to be just like her! I begged Ito-sensei to give me a first time just like hers."
Marin grabbed Sajuna's hands. "Let's be Shizuku-tans together!"
