THE PROPOSITION

Eva stood on Mr. Mike's doorstep, her heart racing, second-guessing this decision for the hundredth time.

She'd only been married to Ryan for three months, and already their sex life was... disappointing. Ryan was sweet, successful, a good provider. But in bed? He was vanilla, quick, and frankly, inadequate. Eva had needs she didn't even know existed until they weren't being met.

And then there was Mr. Mike.

Their neighbor. The man who'd helped them move in, who always had that knowing smile when he looked at her, whose eyes lingered just a bit too long on her ass when she wore yoga pants. Eva had felt the heat of his gaze, the intensity of his presence, and she'd been both intimidated and intrigued.

She'd learned from neighborhood gossip that he was "connected"....some kind of street lord with a reputation. But she'd also heard whispers about his other reputation. The one that made married women blush and look away. Something about being a "sex demon" who could fuck for hours, who left women ruined for anyone else.

Eva had laughed it off as exaggeration.

Until now.

Until her desperation for better sex had driven her to his door at 10 AM on a Monday when Ryan was at work, wearing a sundress that showed off her curves, her thick thighs, her ample breasts, and yes—the ass that Mr. Mike couldn't stop staring at.

She knocked.

The door opened, and there he was.

Mr. Mike was six-foot-five of pure masculine dominance. Dark skin, muscles that strained against his white t-shirt, arms covered in tattoos, a face that was both beautiful and dangerous. He looked her up and down slowly, deliberately, and Eva felt naked under his gaze.

"Eva," he said, his voice deep and rough. "This is a surprise. Ryan at work?"

"Yes. I... I need to talk to you about something. Can I come in?"

His smile was knowing, predatory. "Of course. Come in, beautiful."

She stepped into his house....bachelor pad with expensive furniture, dim lighting, an atmosphere that screamed masculinity and sex. He led her to the living room, and she sat on his leather couch, suddenly very aware of how her dress rode up her thighs.

"So," Mr. Mike said, sitting across from her, his legs spread wide in a posture of complete confidence. "What brings Ryan's pretty little wife to my door on a Monday morning?"

Eva's face burned. "This is embarrassing."

"I'm sure I've heard worse."

She took a deep breath. "Ryan and I... our sex life isn't great. Actually, it's terrible. He's... small. And quick. And doesn't really know what he's doing. I thought maybe it would get better but it hasn't and I don't know what to do."

Mr. Mike's expression didn't change, but his eyes darkened with interest. "And you're telling me this because...?"

"Because I've heard things. About you. That you're... experienced. And I thought maybe you could give me advice. Tell me how to spice things up with Ryan. Make it better."

"Advice." He repeated the word like he was tasting it. "You want advice."

"Yes. Please. I don't know who else to ask."

Mr. Mike leaned forward, his elbows on his knees, and the intensity of his gaze made Eva's breath catch. "Let me ask you something, Eva. How small is Ryan?"

Her face burned hotter. "Maybe... five inches? On a good day?"

"And how long does he last?"

"Five minutes. If I'm lucky."

"And does he make you come?"

"Never."

Mr. Mike sat back, shaking his head. "Baby girl, your problem isn't technique. Your problem is you married a man who can't satisfy you. No amount of 'spicing things up' is going to fix that."

Eva's eyes filled with tears. "So there's nothing I can do?"

"I didn't say that." He stood, moving closer, and Eva had to tilt her head back to look at him. "I can teach you things. Show you what real pleasure feels like. Give you an... education. But it's not advice I'd be giving you, Eva. It's hands-on instruction."

Her pulse quickened. "What do you mean?"

"I mean I'd be fucking you. Teaching your body what it needs. Showing you what a real man feels like. And after three days with me, you'll either go back to Ryan and pretend to be satisfied, or you'll realize what you're missing and come back for more."

"Three days?"

"That's how long it takes. Three days of intensive training. Your body, your pleasure, your education." He cupped her jaw, tilting her face up. "But I need to be clear about something, Eva. If we do this, I'm going to ruin you. By the time I'm done, Ryan's dick will feel like a toothpick. You'll never be satisfied with him again. You'll always be thinking about me, about my cock, about the way I made you scream. So you need to decide right now if that's what you want."

Eva knew she should leave. Should say no. Should go home to her husband and try to make it work.

But God help her, she wanted this.

"Yes," she whispered. "Teach me."

Mr. Mike's smile was pure sin. "Good girl. Let's begin your education."

 THE FUNDAMENTALS

Mr. Mike didn't waste time.

The moment Eva agreed, he pulled her up from the couch and kissed her...hard, demanding, his tongue invading her mouth while his hands gripped her ass, squeezing the flesh that he'd been watching for months.

"Jesus Christ," he groaned against her lips. "This ass. I've been dreaming about this ass since you moved in."

He walked her backward to his bedroom....a massive space dominated by a king-size bed with black silk sheets. He pulled her dress over her head in one smooth motion, then removed her bra and panties, leaving her completely naked.

"Goddamn," Mr. Mike breathed, his eyes traveling over every inch of her body. "Ryan is a fucking idiot for not worshipping this every single day."

Eva's confidence grew under his hungry gaze. Her body wasn't perfect....she had curves, softness, thickness in her thighs and ass....but Mr. Mike looked at her like she was a goddess.

"On the bed," he commanded. "On your back. Spread your legs."

Eva obeyed, her heart pounding, and watched as Mr. Mike stripped off his shirt, revealing a torso carved from stone....abs, chest, shoulders that could carry the world.

Then he removed his pants.

Eva's eyes went wide.

His cock sprang free....sixteen inches of thick, veined, dark perfection. It was massive, intimidating, beautiful, and utterly terrifying. She could see the veins pulsing along the shaft, the head already glistening with precum, and she had no idea how something that size would fit inside her.

"That's... oh my God."

"Lesson one," Mr. Mike said, climbing onto the bed between her spread legs. "Size matters. But technique matters more. Watch and learn."

He lowered his head between her thighs, and Eva gasped as his tongue made contact with her clit. He worked her with expert precision....licking, sucking, flicking in ways that Ryan had never even attempted. Within minutes, Eva was moaning, her hands fisting in the silk sheets.

"That's it," Mr. Mike murmured against her pussy. "Let me hear you. No holding back in my bed."

He inserted two fingers inside her, curling them to hit her G-spot while his tongue continued its assault on her clit, and Eva came with a scream...her first orgasm from someone else's touch in her entire marriage.

"Good girl," Mr. Mike said, not stopping. "That's one. Let's go for two."

He made her come three more times with just his mouth and fingers, and by the time he finally lifted his head, Eva was shaking, oversensitive, completely wrecked.

"Lesson two," he said, positioning his massive cock at her entrance. "You need to learn what real penetration feels like."

He pushed inside slowly, and Eva cried out at the stretch. He was so big, so thick, filling her in ways she'd never been filled. Ryan had never even touched the sides....Mr. Mike was stretching her impossibly wide.

"Breathe," he commanded. "Relax and let your body adjust."

Inch by inch, he worked his way inside, and when he finally bottomed out, Eva was sobbing with the intensity of it.

"You feel that?" Mr. Mike asked, holding still. "That's what it should feel like. That fullness. That stretch. That's what you've been missing."

Then he started to move.

Long, deep strokes that hit every nerve ending, that made Eva see stars, that had her screaming his name within minutes. He fucked her for an hour straight....changing positions, adjusting angles, showing her what her body could do when properly stimulated.

"Lesson three," he grunted, flipping her onto her stomach, pulling her hips up so her ass was in the air. "Ass worship."

He pounded into her from behind, his hands gripping her ass cheeks, spreading them, his thumb pressing against her asshole.

"Tomorrow," he promised, "I'm going to teach you about anal. Prepare yourself."

He made her come six more times before he finally allowed himself release, filling her with hot spurts of cum that seemed endless.

When he pulled out, Eva collapsed on the bed, unable to move, her body singing with satisfaction.

"Day one complete," Mr. Mike said, pulling her against his chest. "Rest. You'll need your strength for tomorrow."
