Early the next morning.
"Mm… that's a lot of energy…"
Leo held Tsunade in his arms. One hand kneaded the soft flesh of Tsunade's chest while she slept, the other stroked his chin, now rough with stubble.
Last night, Tsunade had probably lost emotional control because she had nearly gotten herself killed saving someone.
So instead of sleeping, she'd dragged Leo into doing this and that, that and this, deep into the night—and she'd been extremely proactive. For nearly half the time, she'd been on top, pounding him so hard that Leo was fairly certain his pelvis had shifted out of place.
But there was no denying it.
It felt damn good.
And even better was something else entirely.
The energy points gained each time he slept with Tsunade had increased.
Not a small increase—a massive one.
Leo hadn't noticed the first time, but when he opened the system interface afterward, he was completely stunned.
1,680 energy points.
In one night, it surpassed all his previous efforts combined. Not only was it more than enough for Tsunade to return to her own world, it was already close to covering the energy needed to send Kelly back as well.
It was absurdly shocking.
But Leo knew exactly why.
"You really are a headache of a woman… You even call out the wrong man's name when you're with someone else. Do you actually have feelings for me, or not? It's seriously confusing."
Squeezing Tsunade's chest, Leo complained helplessly.
Last night, while Tsunade was slamming her hips into Leo's pelvis and reaching her limit, the name she cried out wasn't his.
It was Dan Katō.
That almost made Leo go limp on the spot.
And worse still—when Tsunade activated the Strength of a Hundred Seal and still lost because her body was too sensitive, she collapsed on top of him and muttered things like, "Dan… I'm sorry…"
It left Leo completely unsure whether Tsunade had feelings for him at all.
Or whether he was basically playing the role of a cuckold.
"There are studies saying that the man who takes a woman's first time leaves an unforgettable mark—something she'll never forget for the rest of her life. The same goes for a man's first love. But even if that's true, this feels a bit too effective. And how does someone like Tsunade even factor into that?"
With the Strength of a Hundred active, every time Leo dared to fully pull out, that thin membrane would regenerate instantly—only to be torn through again under Tsunade's monstrous strength.
For Leo, it was overwhelming stimulation.
For Tsunade, it was the same.
Thanks to the mysterious reinforcement his body now had, Leo could barely endure it. Without it, he'd have been completely wrecked. As for Tsunade, she was repeatedly experiencing the cycle of tearing and regeneration—painful, yet exactly the kind of sensation she secretly enjoyed. For someone like her, who liked things a bit rough, the Strength of a Hundred actually made her easier to deal with.
Still…
As Leo was grumbling to himself, Tsunade suddenly opened her eyes.
She didn't swat his hand away like usual. Instead, she calmly pushed what he'd slipped out back inside, climbed back on top of him, and grabbed him by the collar.
"Huh? You've got the nerve to complain about me?"
She moved slowly as she spoke, glaring down at him.
"You're the same! Who's name were you shouting? Nakiri Erina!"
Leo went silent for a moment, then answered righteously.
"She was my first woman."
That only made Tsunade angrier.
"Then what about Mai Shiranui? Tifa Lockhart?!"
"…Ah."
Leo had nothing to say.
"Enough! You're just a bastard! Hurry up and stockpile the energy to send me back! Hurry up and send me away already! I don't want to see your stupid face anymore!"
She said that—but not only did her hips keep moving, they sped up and pressed down harder.
And Leo suddenly realized something.
Tsunade…
Wait. Doesn't she have hemophobia?
Through the flickering white flashes in front of his eyes, Leo looked down between them. Sure enough, there was a red-and-white mess visible—despite the fact that just last night she'd still been afraid of it…
As he was thinking that, Tsunade noticed his gaze too. She looked down, froze, and then went completely limp again, collapsing onto his chest.
The sensation of that soft body falling against him was incredible.
Leo let out a helpless sigh. If Tsunade could actually cure her fear of blood by losing her virginity over and over, wouldn't that be a good thing?
But unfortunately—
She still hadn't gotten over it.
So after getting scolded, Leo lifted Tsunade off himself and laid her back down on the bed.
"As for the energy points… honestly, it's already enough, Tsunade."
As he pulled back, Leo even poked at the passage that couldn't get pregnant. He was curious—but there was no way Tsunade would agree, and without proper tools, it would've just been stirring a mess.
So he never tried it.
He'd always kept things normal. Proper.
After all, the women around him were all decent, serious women. He didn't have the heart to treat them badly.
But—
While he was thinking, his footing slipped.
As he braced himself by grabbing Tsunade's towering chest and was about to move again—
The steel door was kicked open.
Kelly stormed into the room.
"You said… it's enough now?"
