"Sister, if I put this on, can I really become Kars's wife?" Flandre, who was brought into the bedroom by Remilia, quickly changed her clothes after hearing her sister's explanation. Although, it was less clothes and more lingerie: pure white panties and bra, along with white thigh-high stockings, with purposeful cutouts in the slightly more essential areas.
"Yes, that's absolutely true. Look, I'm dressed the same way, aren't I?" Remilia, dressed identically, answered Flandre's question. She didn't have a formal wedding dress, but what mattered to her was the sense of ceremony. The room's decor was sufficient, and other details could wait for the actual wedding. This current attire was merely to add some excitement.
"But Flandre just wants to know why you have to wear it too, Sister?"
Remilia: (ー_ー)!!
Oh, come on. Did she think I shouldn't wear this? Did she think I couldn't be Kars's wife? I can't believe you think that way.
"Why wouldn't I be able to? Besides, this was originally supposed to be just me. I brought you along because it was important, and now you don't think I should be here." Remilia couldn't help but feel a little hurt. She felt it was necessary to bring Flandre along, but Flandre clearly disagreed.
"Hehehe! Flandre was just kidding! After all, you told Flandre she couldn't be Kars's wife before!" Flandre laughed, sticking her tongue out at Remilia, causing Remilia to sigh.
"Alright, now just wait here patiently for Kars."
Just as Remilia finished speaking, the door opened. Both their eyes turned toward the doorway where Kars stood, momentarily stunned by the room's decor and the sight of the two on the bed.
"Why are you just standing there?" Remilia urged Kars to come closer.
"Oh!" Kars reacted, nodded, closed the door, and climbed onto the bed. His heart began to pound faster as he took in the sight of his two young aunts' attire.
"Kars, does Flandre look pretty in this?" Flandre impatiently asked Kars if she looked beautiful in her outfit. Kars nodded repeatedly.
"Very beautiful!"
Being gazed at by Kars's fiery eyes made Flandre feel a little shy. She instinctively covered her chest with her hands but quickly lowered them, allowing Kars to continue looking at her body.
Remilia watched the mutual gazes between the two, which seemed to exclude everyone else, and let out a soft huff, causing Kars's attention to shift to her.
"Alright, now is the time for something very important. Stop staring foolishly at each other. Kars, take off your clothes."
Hearing Remilia's words, Kars completely undressed. Remilia and Flandre then sat together in front of him.
"Well, we're starting now." Remilia leaned forward and kissed Kars's lips, their tongues intertwining. Simultaneously, Kars's hands gently stroked her breasts.
Then, he felt a warm, wet sensation enveloping him below. Kars shifted his gaze slightly and saw Flandre bending down, taking his manhood into her mouth, and beginning the same service she had provided before.
Kissing Auntie Remi while being serviced by Auntie Flandre gave Kars a unique pleasure he hadn't experienced before. He quickly became captivated by it, and the pleasure made his tool respond uncontrollably.
He instinctively reached out and pressed down on Flandre's head, making her speed up a little. Noticing this, Remilia stopped kissing. The strands of saliva that pulled apart as their lips separated looked incredibly provocative.
Remilia then bent down toward his tool, allowing Kars to release Flandre's head. She and Flandre then licked him together. Their soft tongues covered his entire length with their saliva, giving Kars an intensely comfortable sensation. Finally, unable to hold back, he erupted, splashing onto both their faces and into their mouths.
Afterward, the two continued to lick Kars's tool clean together. Remilia and Flandre then began to clean the fluid remaining on each other's faces.
"And now for the final step." Remilia had Flandre lie on the bed, positioning her legs in an 'M' shape. Remilia then lay over Flandre, lifting her hips slightly, and used her hands to spread open her own private area, clearly exposing everything to Kars.
Remilia looked at Kars with an alluring smile and said, "So, Kars, whose would you like to try first? Mine? Or Flandre's?"
"Try… try what?" Seeing Kars's confused expression, Remilia realized she hadn't mentioned this to him yet.
"This coming-of-age graduation requires you to use your tool to enter us! So, I'm asking you, whose do you want to enter first? You can choose either one."
Kars understood after hearing Remilia's explanation. He moved closer to the two, his eyes fixed on their intimate areas. He placed his hands on Remilia's buttocks and began stroking them. Then, as she had instructed, he positioned his tool against Remilia's opening.
"Very good." Remilia smiled, watching Kars gently rub his tool against her, and then, finding the exact spot, he thrust in without hesitation. It entered completely, filling and stretching her internal space, making Remilia let out a sharp cry of pain. A trace of blood dripped onto the pure white sheets, causing Kars to tense up, thinking he had made a mistake. Remilia quickly spoke up:
"It's alright. This is normal. So, Kars, continue now. Start slowly, bit by bit…" Remilia quickly reassured and continued to instruct Kars.
Slightly relieved, Kars began to move as Remilia instructed. Starting at a slow pace, he transitioned to a normal rhythm of thrusting, kissing the inner walls of her chamber and making Remilia emit sounds of blissful satisfaction.
Lying beneath Remilia, Flandre watched her sister's expression and began to eagerly anticipate when it would be her turn.
