Yuna went silent, completely silent. She stared at the picture on his phone, and Makoto couldn't read her expression at all.
Mika took a calm sip of her coffee. "She's very good," she said softly. "Her makeup is flawless."
Makoto gulped. "Ehem, that's a good costume, I guess."
His body betrayed him immediately. Despite everything, he felt himself getting hard as he looked at the photo.
"I bet she just called me over to help her make the weapon props or something, haha." His smile felt pathetic even to himself.
Yuna wasn't looking at his face anymore. Her cold eyes traveled slowly down his body and stopped at his lap. She stared at the obvious bulge straining against his pajama bottoms.
A terrifyingly sweet smile spread across her face.
"Weapon props, huh?" Her voice came out low and dangerous. "It looks like you've already got your 'weapon prop' all ready to go."
She leaned closer, dropping her voice to a whisper. "You really are a disgusting, predictable pig, big bro. One picture of some slut in a cheap cosplay, and you're instantly hard."
Mika had been watching everything with calm detachment. She set her coffee cup down with a gentle click.
"Oh, don't be so hard on him, Yuna," she said in that innocent voice of hers. It's only natural for our Makoto to get excited about a new project." Her gaze flicked to his groin, then back to his face, her eyes sparkling with something wicked.
Makoto scratched his head, trying to salvage the situation. "Umm, how about a... compromise?"
He looked between them both. "If you're both worrying that I might do something unfaithful... Maybe you can... drain me dry before I go, so I can't... get hard anymore?"
The two girls looked at each other. Something passed between them in that glance.
Yuna's furious glare met Mika's calculating gaze. There was a flicker of understanding. They recognized their common enemy and their common goal.
Yuna's smile turned feral. Mika's smile turned devastating. They turned back to him in perfect sync.
"Drain you dry?" Yuna repeated, amused. She crawled onto the bed with fluid grace. "That's not a compromise, brother. That's a reward."
Mika joined her on his other side, moving with the same predatory elegance. "But we'll do it," Mika murmured. "So you can keep your fidelity."
She leaned in, her breath warm against his ear, her hand already grabbing his erect cock. "And because we were planning to do it anyway."
...
Makoto lost track of how many times he ejaculated, or where he cum.
The next thing he knew, he was waking up in a sticky mess with the clock pointing at three in the afternoon.
There was something wet on his cheek. He could hear intense whispering somewhere nearby.
The room looked like a disaster zone. The breakfast tray lay overturned on the floor, coffee and toast scattered everywhere. Blankets tangled, pillows askew, and the air thick with the musky scent of sex.
He was naked, sprawled across the bed. His body showed evidence of their possession everywhere: bite marks, scratches, dried cum, and love juices he didn't want to think about. He ached in places he didn't know could ache.
At the foot of his bed, Yuna and Mika huddled together like conspiring generals.
Yuna scrolled through her phone with fierce determination while Mika leaned over her shoulder, pointing at the screen. They were both dressed in their normal clothes, looking surprisingly fresh and energetic.
"No, that one's too obvious," Yuna was saying quietly. "We need something subtle. Something that says, 'He's ours, and if you touch him, you'll find your tires slashed and your cat shaved.'"
Mika giggled softly. "I like the one with the leash. It's a classic for a reason."
They both looked up at the same time, their eyes locking onto him.
Cold sweat ran down Makoto's back. "Ahem, how long did I sleep? No... that's not important. What are you two talking about?"
Yuna's smile was pure evil. "Oh, nothing important. We were just planning your social life." She turned the phone around.
It was an Amazon shopping page. The item displayed was a simple black leather collar, with a small silver ring in front.
"We were just discussing your new accessory," Yuna explained, her voice too cheerful.
Mika leaned forward with that innocent expression of hers. "We think it would really suit you. It's very slimming."
Yuna scrolled down the page. "And look," she said triumphantly. "It comes with a matching leash." She looked at Mika with wicked eyes. "I think we should get two."
Makoto cleared his throat. "Ahem, you should just... not spend too much on that."
He pointed at his flaccid cock. "So... can I go now?"
Yuna and Mika exchanged a look. Another silent agreement was passed between them.
"Go?" Yuna repeated, amused. "Oh, you're still going? Fine." She stood gracefully. Mika followed, mirroring her movements.
"But first," Mika said softly. "A little insurance."
Yuna pulled out a small lipstick from her purse. Deep, vibrant crimson. Mika pulled out an identical one, but hers was a soft, unmistakable pink. They advanced on him, their smiles showing both fury and undeniable desire.
"We're just going to give you a little going-away present," Yuna said sweetly.
"Something for Ayane to remember us by," Mika added hopefully.
They leaned in from both sides, their breath warm against his cheeks. Then they started kissing him. Everywhere: his face, his neck, his chest, his stomach. Each kiss left a lipstick stain, a small declaration of ownership.
When they finished, he was covered in pink and red kiss marks.
"There," Yuna said with a low growl. "Now you can go."
"You should have fun on your project," Mika added, too sweetly.
Makoto grumbled, though he felt happy and content from all their kisses. "You two will pay for this. Don't blame me if you're both covered in my hickeys the next time you go to school."
