"???"
Sajuna was baffled. Be Shizuku-tans together? Then it clicked. She means being sex slaves together!? Does she think I'm a total nympho?
Normally, Sajuna would have screamed in protest, but after what just happened... she couldn't.
"I... I'm not interested in that." She looked away, wearing borrowed clothes. She couldn't look Marin in the eye.
"Really? Not at all?"
"No!"
"Alright." Marin didn't push. Asking someone to be a "sex slave" right off the bat was a bit much. But looking at Sajuna's "sensitive" body, Marin figured it was only a matter of time.
"So, what now? Do you want to see the rest of the con or should we take you home?"
"Um... you guys are still at the con, right? I'll wait here." Sajuna didn't want to ruin their day by making them leave early, and she certainly didn't want to go home in a butler suit with her own piss-soaked clothes in a bag.
"I'll stay here with you."
"Eh!? No, you don't have to! You cosplayed Shizuku for this event, and it just started..."
"It's fine. I can cosplay anytime. Besides, my mind isn't on the con today... I'll tell you a secret: I climaxed when I was sucking his fingers, too."
Marin saw that Sajuna was drowning in shame. Sharing a "dirty secret" was the fastest way to bridge the gap.
"Really?"
"Yeah!" Marin whispered into Sajuna's burning ear. "In the hall earlier, I soaked my panties through. I only came back to the car to change them."
The tension eased. They were both fans of each other and had now shared a very awkward experience.
"But still... I've got nothing on Juju-sama, passing out just from watching."
"!!!!" Sajuna's face turned beet red. "I... I..."
"Sajuna," Marin said, her voice dropping. "Do you want to know what the real thing feels like?"
Sajuna's toes curled. It was an embarrassing question, but she had to know. If watching did that to her, would the real thing kill her? And she couldn't ask anyone else. She went to an all-girls school; her friends were either virgins or into other girls. Her mom was out of the question. Only Marin, who had seen her at her most pathetic, could be asked.
"I don't know yet. I'm still a virgin."
"Wait... you too?" Sajuna was stunned. A woman who climaxes from sucking a finger is a virgin? Then again, she herself had climaxed just from watching. "But aren't you his... Shizuku? His slave?"
"You think I'm the type who just likes casual sex, don't you?" Marin smiled. "The 'parties' we have are interesting, though."
"Normal parties?"
"Slutty parties."
"..." Sajuna didn't know what to say.
"It's not for mindless lust. It's... well, people with different fetishes gather. You can participate or just watch. And there's only one man: Ito-sensei."
"Who is this Ito-sensei?" Sajuna asked. This sounded like a harem from a visual novel.
"He's an eroge artist. One of my friends joined because she likes 'perverted play' but was scared of bad people. Another does it for 'research' for her own games... Ito-sensei is a good man. He helped a girl who was a shut-in for two years because of trauma. That's why we trust him."
"As for me... I wanted to be Shizuku. But Shizuku is a slave, and you can't just let anyone play the 'Master'..."
Sajuna was quiet. It sounded logical, in a very twisted way.
Marin watched her closely. She hadn't planned on dragging Sajuna into this—Juju-sama seemed too pure for 18+ stuff. But after seeing her body react like that...
I want to see it. I want to see Juju-sama cosplaying a magical girl while making an 'ahegao' face!
A pure magical girl being captured and "corrupted" was a classic trope. Forced to serve the villain while pretending to be a hero to her friends, only to fall deeper into depravity...
The thought made Marin press her own legs together. She took a deep breath.
"I already have a promise with Ito-sensei. After the con, he's going to play the 'Master' and take my virginity... just like the protagonist does to Shizuku."
"Juju-sama... do you want to watch? Watch me being 'trained' just like her?"
Gulp. Sajuna swallowed hard.
