“If we’re talking percentages, you’re basically asking me to live on a starvation diet while you’re feasting at a buffet,” I said, pulling Lauren against me. I let my hand slide down the curve of her hip, squeezing the firm flesh of her backside with a possessive grip. I could feel the heat radiating off her, and God, the smell of her skin, like vanilla and something sharp, something electric, was driving me insane. I wanted her right here, on the kitchen island, with her legs wrapped around my waist and her breath hitching in my ear.

Lauren laughed, a melodic sound that only made me want to devour her more, but she gently pushed my hand away. “Greg, honey, three or four times a week is a healthy, sustainable pace. Getting you off twice a day is a full-time job. I’m exhausted just thinking about it!” She leaned back, her eyes sparkling with a mixture of amusement and genuine fatigue.

I groaned, pressing my forehead against hers. “But I’m a growing boy with needs, babe. I’m practically starving for pussy and boobs.”

Inconveniently, the swinging door to the kitchen creaked open. Olivia trotted in, the cute redhaired teen’s mismatched socks sliding across the hardwood. She stopped dead, looking at us with that wide-eyed, unnervingly observant stare she’d inherited from her mother. “Why are you hugging so weird?” she asked, tilting her head.

Lauren didn’t let go of me, but she shifted her gaze to her daughter, her voice softening. “Well, sweetie, Greg and I were just talking about the future. After we get married next month, we’re thinking about having a baby. That means you’d have a little brother or sister.”

Olivia’s expression shifted instantly from curiosity to a look of sheer, focused horror. She crossed her small arms over her chest and frowned. “No! No way! I don’t want a baby! I want to be the only one. If there’s another kid, you guys have to share the love and the presents, and that’s not fair!”

I chuckled, the sound vibrating deep in my chest, while my mind was still stubbornly fixed on the friction of Lauren’s thighs against mine. The conversation about progeny was a distraction from the immediate, pulsing urgency in my gut. “We’ll talk about it later, Liv,” I said, my voice a bit too husky to be casual. “Right now, some grown-up has to go make some money so you can keep buying those expensive collector dolls, and weirdly colored socks.”

I didn’t let her answer. I stepped back just enough to wrap my arms around Lauren, pulling her into a kiss that was far too hungry for a Tuesday morning. It wasn’t a ‘goodbye’ kiss; it was a claim. I tasted the mint of her toothpaste and the lingering heat of her skin, my tongue tracing the seam of her lips with a deliberate, slow pressure. For a second, I felt her melt, her breath hitching in a way that told me she wasn’t as ‘exhausted’ as she claimed to be.

Suddenly, a loud, theatrical “Ewwwww!” erupted. Olivia was scrubbing her eyes with her fists, acting out a scene of extreme disgust. Lauren broke the kiss, laughing and breathless, her cheeks flushed a deep, inviting crimson. “Go! Get out of here!” Lauren giggled, giving me a playful shove toward the door. “See you tonight.”

“Love you. Have a nice day.” As I walked toward the car, my mind was already mapping out the friction of the evening. I could still feel the phantom pressure of Lauren’s body against mine, the way her scent clung to my shirt like a challenge. I drove to the office in a state of semi-conscious agitation, my focus entirely on getting her back in bed the second I stepped through the door.


Meanwhile, the kitchen had returned to its domestic stillness, though the air still felt charged. Lauren leaned against the counter, letting out a long, shuddering breath that she’d been holding since the moment Greg’s lips left hers. She looked at Olivia, who was still making a face of profound disgust, though the curiosity was starting to override the “eww” factor.

“Mom?” Olivia asked, her voice suddenly small and inquisitive. “How do babies start? How do they get in a girl’s belly?”

Lauren froze. She looked at the clock, then at her daughter, realizing there was no way to dodge the important conversation. She took a deep breath, trying to keep her voice neutral despite the lingering heat in her own belly. “Well, honey ... it’s a bit complicated. You see, men have something called sperm, and the slit, the hole between a woman’s legs is called a vagina. When a man and a woman love each other very much, and they want to make a baby, the man puts his sperm in her vagina. Then, that little bit of sperm swims to find a tiny egg, and if they meet, they start to grow into a baby.”

Olivia stared at her, her brow furrowed in intense concentration. “So ... he just puts it in there? Like a letter in a mailbox?”

Lauren winced slightly, the mental image crossing with the memory of Greg’s possessive grip on her hip just minutes ago.

“Something like that, sweetie. It’s a very special, private way adults share love. Enough science for one day,” Lauren announced, her voice regaining its maternal authority, even as her thoughts lingered on the ‘special attention’ Greg needed. “Go get ready for school. The yellow monster will be here in ten minutes.”

“But I don’t want to go to school! I want to know more about love and babies.”

Lauren playfully swatted her bottom lightly. “Go. I’ll teach you more before your first date. Fourteen is too young for all the details.”


“Wait, so it’s like a key in a lock? Or like when I put my Lego man in the little plastic house?”

Olivia’s voice cut through the silence of the dining room like a scalpel through a steak. I nearly choked on my red wine, the liquid spraying slightly across the tablecloth. I looked at Lauren, pleading for a rescue, but she just leaned back in her chair with a look of profound, maternal patience that bordered on sadistic. I felt the heat crawl up my neck, my face turning a shade of crimson that matched the Cabernet.

“Well, uh ... you see, Liv,” I stammered, the words tripping over each other in a frantic race to stay PG. “It’s ... it’s a very biological process. There are ... cells ... and chemistry ... and, you know, the plumbing is a bit complex.” I glanced at Lauren, my eyes screaming help me, but she just smiled, that slow, knowing curve of her lips that usually preceded her telling me ‘no’ to a third round of sex in a day.

Lauren didn’t miss a beat. “Honey, Greg is just nervous. Look, Olivia, men have a penis between their legs, it’s a bit like a wiener. The penis goes inside a girl’s vagina. It feels very good, but it’s also how babies are made. Because it’s so adult and ... well, dangerous for a girl’s body, it’s something you only do when you’re grown-up.”

The honesty of it hung in the air, raw and clinical. I cleared my throat, the embarrassment shifting into a sudden, mischievous impulse. I looked at Lauren, then back at Olivia, a smirk tugging at the corners of my mouth. “Of course,” I added, my voice dropping an octave, “a penis in a mouth doesn’t make babies, and it feels very good too.”

The room went silent. Lauren’s eyes widened. A mixture of shock, resentment, and arousal confused her emotions.

Olivia didn’t even blink. She looked at me with a purely logical, child-like focus, as if we were discussing the proper way to stack building blocks. “Then you should just put it in her mouth,” she declared, her voice ringing with absolute certainty. “If that’s how you do it without making a baby, just put it in her mouth all the time. I don’t want a sibling. Especially a bratty little brother!”

Lauren’s jaw practically hit the table. She looked at me, her face a cocktail of disbelief and a sudden, sharp spike of desire that she was trying desperately to hide from our daughter. I felt my pulse thrumming in my throat, the sheer audacity of a fourteen-year-old’s logic acting like a shot of adrenaline straight to my groin. I couldn’t help it. A slow predatory grin spread across my face as I looked at the woman I wanted to devour.

“Right. Bedtime. Now!” Lauren managed to choke out, her voice an octave higher than usual. She stood up with an abruptness that nearly knocked over her wine glass. “Olivia, march. To your room. No more talking about ... babies.”

As Olivia trotted away, still humming a little tune and clearly proud of her solution, Lauren collapsed back into her chair. She let out a long, jagged breath, her chest heaving. The silence that followed was heavy, charged with a sudden, electric tension that made the air feel thick.

I didn’t say a word. I just leaned forward, my eyes locked on hers, letting her see exactly what I needed. I reached out, my fingers grazing the sensitive skin of her wrist, and watched a shiver race up her spine.

“Blowjobs are great! If she doesn’t want a baby, I guess you have to...”
