for Advance Chapter
Sitting on the edge of the bed, the signs of two people living together were everywhere. Her boyfriend is real, Yoshida thought, feeling an indescribable weight.
The door pushed open. Ms. Goto walked in wearing her office attire—the look he saw her in every day at work.
"H-How is it? I thought you might like this..."
She tucked a strand of hair behind her ear and hugged her arms under her chest, emphasizing her curves. The top three buttons of her shirt were undone, revealing her collarbones and the deep cleavage between her massive breasts.
"It's fine. But... why this outfit?"
"Because... you always look at me with such naughty eyes at work."
She sat beside him, her skin a faint, tempting pink from her recent bath or rising lust.
"So you knew."
Yoshida reached out and pulled her into his arms. Their lips met. Their kiss was deep and messy, a far cry from the pure, innocent first kisses of youth.
Before things went further, Ms. Goto slid off the bed and onto her knees between his legs. Her eyes, hazy with wine and desire, looked up at him through her lashes. She slowly unzipped his trousers, her movements deliberate and practiced. When his turgid member sprang free, she let out a soft, admiring gasp, reaching out to stroke the length of it with her soft, warm palm.
"Yoshida-kun... it's so big..."
She leaned in, her tongue flicking out to tease the sensitive head before she engulfed him completely. The heat of her mouth was staggering. She used her tongue to swirl around the ridge, applying a rhythmic suction that made Yoshida's hips buck involuntarily. Her throat was tight and wet, and she bobbed her head with a focus that showed she wanted to savor every inch of him. The sound of her wet, sloppy sucking filled the quiet room, a primal melody of submission and lust.
He noticed her phone on the table was constantly lighting up with notifications.
"Don't you want to check that?"
"Is it okay?" she asked, pulling away with a wet pop, her lips glistening.
"He's the official boyfriend. And... I'm curious too."
"If you don't mind..."
Ms. Goto sat in his lap with her back to him, her skirt hiked up around her waist. He could easily see the screen, but he controlled his curiosity, choosing instead to kiss her neck.
"Sorry, wait a second. You can... you can play with these first..."
She took his hand and pressed it against her chest. So big... so heavy... so soft. He finally held the breasts he'd dreamed of for five years. He unbuttoned her shirt. She wasn't wearing a bra.
"Just how big are these?"
"...H-cup, hehe~"
"H-cup?!"
He began to knead them, counting through the alphabet with his fingers. He squeezed the heavy mounds, watching them spill over the sides of his hands, the pink, large areolae hardening under his touch.
"That tickles! You're like a child, Yoshida-kun~"
She set the phone aside and straddled him, burying his face in her cleavage. The scent of her perfume and the musk of her arousal was intoxicating.
"I'm so happy... I'm almost jealous of him."
"Stupid. He's the one... imagining us right now, jealous enough to go crazy..." Her voice trembled as he began to lick her, his tongue tracing the underside of those massive weights.
"You won't regret this?"
"No. Yoshida-kun, how much do you know about cuckoldry?"
"...A bit."
"He... he has that fetish. And because of work, we're often apart... he told me he wanted me to find a lover..."
"Which means..."
"But! Not before you! I've never done this with anyone else like this!"
It was unexpected, but it made sense. If she had been with someone else in the office, he would have noticed.
"When you confessed, I was so happy. I realized I liked you too."
"I thought the 'boyfriend' talk was a rejection."
"You were too impatient! I didn't know how to explain it then."
"So why now?"
"Because... because you have a girl you like now, don't you? I can't give you all my love, but if you—like me—can love two people at once, then I can... I can reach out to you without guilt."
Inside the room, silence fell.
"I'm a bad woman, aren't I?"
"If you weren't a bad woman, I wouldn't have a chance."
The memory of that day by the lamppost surfaced. This time, he didn't let go. They stripped until they were nearly naked, though she kept her black stockings on, bunched around her thighs to reveal her pale, soft rear and her slick, yearning center.
"What about... protection?"
"The box is in the nightstand drawer."
He found the box. It was half-empty. He wondered when her boyfriend had last used one as he rolled it on. It was tight.
"Pass me my phone again... please..."
"Now?"
He handed it to her.
"Come in. Put it inside me."
He pushed his hips forward, guiding himself into her soaking wet fold. There was so much lubrication it stained the sheets, a squelching sound accompanying his entry. His member disappeared between her legs, the tight walls of her vagina clamping around him with desperate heat.
"Ah... Yoshida-kun is inside me... h-haaa!"
Her moans were sweeter than any fantasy. She threw her head back, her h-cup breasts swaying violently with every thrust.
"Wait, stop for a second."
Before he could start a rhythm, she pressed her foot against his chest, stopping his movement. She took a photo of their union—the place where they were joined—and sent it.
"Hey, can't you chat with him after we're done?"
"It's okay. Almost done."
She sent the message, then reached down and—to his shock—pulled the condom off.
"Is this okay?"
"It doesn't matter. I bought the pill. To do it with you through a condom for the first time... that's too lonely. And..." she looked at him with bedroom eyes, "the thought of being creampied by you behind his back... it's so exciting. He'll love it. Don't you want to ejaculate irresponsibly inside someone else's girlfriend?"
"You lewd woman!"
All gentleness vanished. Yoshida drove into her with raw force, his bare skin slapping against hers. The feeling of being inside her without a barrier was electric; he could feel every ridge, the pulsing of her internal muscles as they tried to wring him dry.
"Which of us is bigger?!" he growled, playing into the fantasy.
"Yoshida-kun... yours is bigger. It fills me up so much... I love it~"
"Then break up with him!"
"No, no... I want to date both of you, okay?~"
The more she talked, the more aroused he became. The sounds of friction and slickness filled the room, a wet, rhythmic slapping as he hammered into her.
"I'll let you come inside... I'll even have your baby if he agrees~"
Yoshida shuddered, a bit of fluid leaking out. He stood at the edge of his limit, the pleasure building into an unbearable pressure at the base of his spine.
"Give it to me... I want your child... I want both of your children~"
She pinned him down, straddling him and grinding her hips with a frantic speed that made the bed creak. She was leaning over him, those massive breasts brushing his face as she worked herself onto him.
"Ejaculate, ejaculate! Give it to me! He's done it inside too, don't lose to him!~"
With no protection, Yoshida released everything deep inside her. It was an immense amount, pulse after pulse of hot seed flooding her womb. He groaned, arching his back as he emptied himself into the woman he had desired for years.
She leaned down, kissing him deeply while savoring the warmth inside her, swallowing his saliva as she took his seed.
"Phew... so much. I have to share this with him too~"
She lifted her hips slightly, and the sight of the white fluid leaking from her reddened opening was immediately captured and sent to her waiting boyfriend.
"There, stop crying. I'll take the pill. Be a good boy, stop crying."
Ms. Goto was finally answering her boyfriend's call. Yoshida, feeling weak in the knees, sat up and patted her rear, causing a small squelch of fluid to leak out.
"Ah, wait, what are you doing?"
"I should go home."
"Not staying the night?"
"She's waiting for me."
"I see..."
She hung up and helped him dress, her body still flushed from the encounter.
"Tell me about her sometime."
"Yeah."
"...I'm sorry."
After a long kiss, he began his journey home.
On the train, the void left after ejaculation felt heavy. He thought about a senior he'd dated in high school who had been just as manipulative, just as experienced. He had been obsessed with her until he found her with someone else.
"It's not like you're bad at it... I just wanted to try it... A serious man like you isn't suited for a woman like me... I'm sorry."
He turned the key in the lock. Should he hide it? It didn't matter. Sayu had nowhere else to go. Even if she left, he'd just go back to his old life. Or he could cut ties with Goto and make it a one-night stand.
"Mr. Yoshida..."
Sayu hugged him—this man who looked so lost.
"Heartbreak is painful, isn't it?"
He realized he had "broken up" again. He hugged her tight.
"I'm sorry, I..."
"Ahem! My, my, this customer is so lucky! Congratulations, you've won the prize!~"
He looked up to see Sayu smiling.
"You know, like 'Win another can'? It's like that~"
She cupped his face, trying to smooth his furrowed brow.
"The prize is just a clearance-sale high school girl. Do you want it?"
"But I..."
"Who do you like more? Me or Ms. Goto?"
"You." No hesitation.
"Then that's that. I don't mind, so what are you worrying about? Or do you want me to leave?"
"I don't want that."
"Then say it out loud, or I won't understand."
"Sayu, I love you!"
A light, chaste kiss followed. Sayu felt embarrassed. She should have kissed him like an adult, with tongues and all.
"One more time."
"Sayu, I love you!"
"Stupid, not that part~"
She had to respond to the confession properly.
"I love you too, Mr. Yoshida! More than anyone else!"
