If I Monopolize the First Time of the Exceptionally Skilled Prince

‘You can love others as much as you want. You must not give your whole heart when you love. Even if you love someone sincerely, it is better to keep a certain distance in anticipation of getting hurt.’

Her mother, who is no longer by her side, would hold young Jeanne tightly whenever she was heavily drunk. Then, looking down at Jeanne with eyes full of affection, she would always say the same words.
Ah. Why was she recalling those words right now?
It was because, at this very moment, a secret deal was being exchanged with her as the subject.

“Lilian. What did you just say?”
“I asked whether you couldn’t confess to Jeanne Nova and start dating her.”
“What do you mean? Suddenly telling me to start dating her?”
“Yes. So that she can’t even think about studying and ruins her grades.”

Jeanne had not once lost the top rank since enrolling in the academy. On top of that, she was even a commoner, so it was not entirely incomprehensible that the princess, who had been trailing behind Jeanne year after year, was that resentful.
She had everything, yet she wanted the grades too. But in that moment, a certain thought flashed through her mind.
Her twin brother, Ruhir de Winter, was kind to everyone regardless of status, and was the sort of existence that felt like everyone’s first love.
He had never once dated anyone either.
In that case, what would happen if she, a commoner, took away all of his firsts?
If she kept her distance so as not to get hurt, there would be no problem at all when they parted ways.

“Ruhir.”
“……Yes.”
“It feels good to share all the firsts with Ruhir.”
“—Me, too.”

The wet sound of tongues intertwining echoed through the quiet living room. When they had kissed in the alley, it had been drowned out by the loud noise around them and she had only felt the sensation of their tongues meeting, but now it was different. The lewd sound reaching her ears felt strange and her spine trembled on its own.
After kissing deeply and opening her eyes, she saw Ruhir, his face flushed red like a tomato, unable to even open his eyes properly.
Without realizing it, she stroked his soft hair and pressed her lips to his nose, the corners of his eyes, his cheeks, here and there. Then, lightly biting down on his lip, she was met with a startled gaze.
Jeanne, wiping the corner of her mouth, took his hand and brought it over her shower robe. Then she had him take it off. As her soft br*asts were revealed, Ruhir opened his eyes wide and froze on the spot.
At the sight of him just opening and closing his lips, Jeanne smiled and guided his hand.
As she had him caress her soft chest with his calloused palm, his already red face flushed even hotter.
