The warm steam from the bathtub filled the small bathroom as Yukie slipped out of her revealing slit gown. The crimson fabric pooled at her feet, leaving her completely naked. She straightened her long hair with a graceful flick of her wrist and stepped into the large wooden tub with a contented sigh.
"That's quite refreshing…" she murmured, sinking into the warm water up to her chest. Her massive breasts floated gently on the surface, the deep cleavage clearly visible above the waterline. She leaned back against the edge of the tub, eyes half-closed in bliss.
"This is honestly the best thing in this world so far," she whispered softly, a calm smile playing on her lips.
Suddenly — CRACK! — a small window high on the wall above the tub swung open on its own. A blast of cold evening air rushed in, making Yukie yelp and instantly cross her arms over her chest.
"Oh no! That's so cold!" she complained, shivering as goosebumps rose across her wet skin. She stood up slowly, water cascading down her curvaceous body, and glared up at the offending window. "Who even puts a window in a bathroom like this?"
Rolling her eyes, she closed them and concentrated. A soft pink glow appeared as she conjured a fluffy towel out of thin air and wrapped it tightly around herself. The towel barely contained her enormous breasts, the fabric stretching taut and creating a dangerously deep cleavage.
Lucian sat in the main room, absentmindedly brushing dust off the old leather-bound book. "This looks ancient…"
The bathroom door opened. Yukie stepped out, still dripping wet, the pink towel clinging to her body. She gestured back inside with a slightly embarrassed expression.
"Sweetie, can you help me with something?"
Lucian stood up and followed her back into the bathroom. Yukie pointed dramatically at the open window high on the wall.
"See? Can you close that for me? The cold air is ruining my bath."
Lucian gave her a flat, deadpan stare. "Really? You can't bathe with a little cold air?"
Yukie pouted cutely, looking away shyly. "You don't understand anything about comfort, Lucian…"
Lucian sighed and dragged a wooden chair into the bathroom. "We can use this."
Yukie looked at the chair, then at him, then at the high window. A confident glint appeared in her eyes. "Actually, I think I can reach it myself. This chair is only about 45 cm tall, you're around 163 cm, the wall is roughly 2.6 meters, and I'm 168 cm. I should be able to do it easily."
Lucian tilted his head, confused. "What do you mean?"
Yukie tightened the towel around her body and stepped onto the chair with surprising confidence. "Hold the chair tightly."
She stretched her arms upward, the cold air making her shiver. "Brr… that's very cold…"
With one firm push, she managed to slam the window shut.
Lucian looked up. "Did you do it?"
Yukie turned toward him with a proud smile. "Of course, Sweetie. There's nothing your stepmom can't do—"
Her foot slipped on the wet surface of the chair.
"Kyaa—!"
She tumbled forward directly onto Lucian.
THUD!
They crashed onto the bathroom floor in a tangled heap. Yukie landed on top of him, her huge, towel-wrapped breasts squishing heavily against his face and chest. The impact caused the towel to loosen dangerously, but it somehow stayed in place — barely.
"Ouch…" Yukie winced, then looked down at him with genuine concern. "Are you okay, Lucian?"
Lucian's eyes were wide, his face completely buried in soft, warm cleavage through the towel. "Mmmph—!" was all he managed before his eyes rolled back and he fainted on the spot.
At that exact moment, the door opened.
"Here's your lunch, sir—" Lisa, the fox-eared maid, stepped in with a tray, only to freeze at the sight of Yukie sitting on top of the unconscious Lucian.
Yukie sat up energetically, waving her hands frantically. "It's not what you're thinking! This is my stepson! He was helping me close the window, but my leg slipped and I fell on him!"
Lisa tilted her head, ears twitching. "It's okay, ma'am. I understand," she said softly, placing the tray on the table.
Yukie smiled hopefully, still sitting on top of the fainted boy. "Why don't you help me put him on the bed?"
Lisa looked at Yukie, then down at Lucian's unconscious face, and nodded slowly. "Of course, ma'am." She rolled up her sleeves and walked over to assist.
Yukie let out a dramatic sigh of relief. "Thank you… This world is going to be the death of both of us."
After a while, Lisa sat back down on the chair with a tired look on her face. "It was very difficult," she said with a heavy sigh, wiping the sweat from her forehead.
Yukie nodded, still wrapped in a towel as she sat on the edge of the bed. She wiped the sweat from her face and spoke with a soft, proud tone. "Well, that's good. He's heavy, which means he's having a good diet. I don't want to see him thin." Her gaze then shifted to the covered plate on the table. She stood up and walked toward it. "That smells nice," she said energetically, giving Lisa a quick wink.
Lisa clapped her hands together with a soft, happy smile. "I am very happy that you like this, Ma'am," she replied before standing up.
Yukie covered the plate with another lid and headed toward the bathroom. "You can leave now. I should take a bath," she said in a tired tone, stepping inside and closing the door behind her.
Lisa nodded and walked out of the room, gently closing the door. As she did, an ork man wearing a cap and a suit walked down the corridor.
"Are you finding something, Sir?" Lisa asked politely.
The ork man looked down at her for a moment, then continued straight to his room without a word and shut the door.
"What happened to him?" Lisa asked softly, tilting her head in confusion.
Another maid appeared nearby. "Lisa, you have to take care of the other corridor too," the woman said gently.
Lisa nodded. "I will. Thanks for reminding me, Celia," she replied before walking away.
A little while later, Yukie came out of the bathroom wearing a simple white vest and dolphin shorts that hugged her thick thighs. "Lucian, wake up," she called softly. "Don't you want to eat some tasty beef stroganoff and roast beef?"
Lucian opened his eyes, immediately sniffing the delicious aroma in the air. "Did someone just talk about beef stroganoff and roast beef?" he asked hungrily, getting up and walking toward the plate while following the smell.
Yukie gave him a deadpan look. "A foodie stepson… What else can a woman want in her entire life?" she said in a flat tone as she sat down in front of him.
Both of them started eating with great enthusiasm. "This is very tasty, much better than the dishes from our world," Yukie said softly, licking a bit of sauce from her lips.
Lucian nodded while taking another huge bite. "That's right. This dish is insanely better than anything back home," he replied with an energetic smile. His eyes soon drifted to the mysterious book on the table.
Yukie noticed and followed his gaze. "What are you thinking about, Lucian?" she asked, still eating.
Lucian picked up the book and opened the first page, revealing drawings of various demons. "What type of drawings are these?" Yukie asked, confused, as she leaned forward to examine them more closely. Her large breast pressed lightly against the table through the thin fabric of her vest.
Lucian flipped the page, revealing rows of ancient-looking mantras. "These must be magical spells," he said calmly.
Yukie leaned in further, her expression puzzled as she twirled the fork in her hand. "What do you mean by spells? Does that mean we can actually use magic with these?" she asked.
Lucian rubbed his chin thoughtfully. "That's right. We could use these spells for magic… but who would leave a book like this here?"
Yukie crossed her arms, looking up at the ceiling in confusion. "Maybe someone just put it here by mistake?" she suggested softly.
Lucian rolled his eyes with a skeptical chuckle. "No one forgets something this important. And it looks really ancient. Something feels off about this whole thing."
He smirked slightly, the classic look of someone who had just realized they might have stumbled upon a major isekai cheat item. "Looks like our new world just got a lot more interesting."
Yukie smiled brightly as she finished the last bite of her meal, pushing the empty plate aside with satisfaction. "Stop thinking too much, Lucian. If he can use this book to learn skills, it'll help us a lot — whether in monster battles or earning money."
She confidently grabbed the old leather-bound book and flipped through its yellowed pages. Her eyes stopped on a particular spell, and she rubbed her chin thoughtfully.
"Fire magic… that looks interesting," she murmured softly, examining the runes and instructions with focused curiosity.
Lucian took another bite of his beef, chewing with growing excitement. "That's great! If you learn these spells, we'll make a perfect team. Your mage skills combined with my attacker style — we'll crush monsters left and right."
Yukie nodded enthusiastically and stood up, extending her hand forward dramatically like a true isekai protagonist. "Let me try…"
She looked down at the spell and began chanting in a clear, confident voice:
"Flame of the ancient core, gather and obey. Condense into fury, burn all in my way… Ignis Sphere!"
Nothing happened.
Yukie stared at her empty palm, blinking in confusion.
Lucian stood up and examined her hand carefully, trying to look like an expert. "Maybe you have to use your mana the same way you do when creating items. Focus on that feeling."
Yukie nodded, closed her eyes, and tried again with more concentration:
"Flame of the ancient core, gather and obey. Condense into fury, burn all in my way… Ignis Sphere!"
A small, bright fireball suddenly flickered to life above her palm, crackling with warm orange light.
Yukie's eyes lit up with pure joy. "That's amazing! It's a real fireball on my palm!" she exclaimed happily, bouncing slightly on her toes. Her huge breasts jiggled noticeably inside her vest with the excited movement.
Lucian nodded, rubbing his chin thoughtfully. "Good start. Now try to use your mana to increase the size."
Yukie closed her eyes again, focusing hard. The fireball slowly grew bigger, flames dancing more intensely.
"It's getting bigger!" Lucian said, his tone shifting from serious to genuinely happy.
Yukie opened her eyes and stared at the growing orb with wide-eyed delight. "This is literally amazing, Sweety!"
Then her expression changed. "Wait… how do I make it disappear?"
Lucian's confident smile froze. He grabbed his forehead in sudden panic. "We… don't know how to dispel it yet. Maybe try reducing your mana?"
Yukie nodded frantically and closed her eyes again, but when she opened them, the fireball was still there — now even larger and more unstable.
"I couldn't do it!" she said, her voice rising in terror.
Panicking, she burst toward the bathroom, hand outstretched with the flaming orb. She plunged her arm into the half-filled wooden bathtub.
HISSSSS!
A massive cloud of steam exploded upward as the fireball met the water, filling the bathroom with thick white mist.
Yukie leaned heavily against the edge of the tub, breathing hard. Her huge tits pressed firmly against the rim through the thin fabric of her vest, rising and falling rapidly with each breath.
"We… have to stay careful with these skills," she said, voice tired but relieved.
Lucian nodded from the doorway, still looking a bit shell-shocked. "Yeah… we have to stay careful," he repeated in a calm but slightly traumatized tone.
The steam slowly cleared, revealing Yukie's flushed face and the slightly singed edge of the bathtub. She looked back at Lucian with a weak, sheepish smile.
"…At least I didn't burn the inn down on our first night."
Lucian gave her a long, deadpan stare.
"This is going to be a long Isekai adventure."
