As a Jounin, former ANBU, and former student of the Yondaime, Psycho Minato, I've seen some crazy shit in my life.
But not as crazy as what I saw in Team Seven's training grounds one fine day.
I'm sure you remember my dear students, Naruto and Sakura? Their song-and-dance of the good ol' days?
I LOVE YOU, SAKURA-CHAAAAAAAAAAAAN!
*WHACK!*
So you can imagine my surprise when I saw them dry-fucking in broad daylight. Frenching, her nuzzling his neck, him nibbling hers, him unzipping her top, feeling her up, her dry-humping him…what the! Vines wrapping around me, pulling me away, Yamato growling C'mon!
My surprise is such that I can't shut up about it, even as Yamato takes the boys to his place.—Wow. I mean, just…wow. In a million years, I never thought—I mean, Naruto and Sakura—
—Sempai!
—I'm just saying, Sakura's hitting him one moment then dry-fucking him the next—
—Shut up!
—I mean, she's prolly ripping off his clothes and fucking him against the fence as we speak!
—WILL YOU SHUT UP?
—What? Am I the only one who sees the humor in this?
Incredulity.—I think you might be, sempai.
—Your loss. Ja ne.
I must investigate. If what I saw wasn't a genjutsu (and my Sharingan made sure it wasn't), then Hell's freezing over as we speak.
Outside the window of Naruto's room. Naruto and Sakura wrestling like kids. Her straddling him. Redux of earlier foreplay. Divestment.
Her hand on his knee for leverage as she rides him. Him thrusting upward. Up, down. Up, down. His hands at her hips, steadying.
Faces scrunching in orgasm before collapse in each other's arms.
I again activate my Sharingan. Not a genjutsu. So it is happening, Naruto and Sakura.
Groundbreaking like Sakura's attacks, yes, but the sex…meh, so-so. I've read better hentai on page 45 of Icha Icha Violence.
What a pity. It appears that I won't be able to observe more NaruSaku. They've skipped town to "become outside agents."
Oh well. If that's what Tsunade says, then there's nothing we can do about it.
Yes, I'm perfectly aware of Sasuke's situation and now you are wondering why I don't pity him, especially considering that he was my favorite student.
My answer to you: the Sharingan develops into Mangekyou when your closest bond is dead to you, literally or proverbially. Before he left to give his body to someone who made Michael Jackson look like a beauty queen, I didn't have Mangekyou.
Afterwards, I did.
That alone should answer your question.
