Chapter 3 Brewing Desires

Isabella's POV

The kitchen smelled of fresh coffee and toast the next morning, a facade of normalcy that made my stomach churn. Mom bustled around, humming off-key as she poured herself a mug, adding her usual splash of creamer from the fridge. I watched her from the breakfast nook, my phone hidden in my lap where I'd been scrolling through discreet online forums about poisons. Ethylene glycol antifreeze. Odorless, sweet-tasting, deadly in small doses over time. I could buy a bottle at the auto store, siphon some out, and mix it into that creamer bottle. She'd sip it daily, none the wiser, until her kidneys failed. "Natural causes," the doctors would say. And Daddy? He'd turn to me for comfort, his cock finding solace in my pussy every night, no more hiding.

"Isabella, honey, you want some eggs?" Mom asked, snapping me out of my reverie. Her smile was genuine, oblivious. It almost made me feel guilty. Almost.

"Sure, Mom," I replied, forcing a grin. Daddy sat at the table, newspaper in hand, but his eyes flicked to me, lingering on my short robe that barely covered my thighs. I shifted, letting it ride up just a bit, feeling myself get wet under his gaze. Last night's fuck over the vanity replayed in my mind his promises to end things with Emily, his cum dripping from me as we talked about a future without obstacles.

He cleared his throat, folding the paper. "Big day at the office today. That merger's closing soon." His voice was steady, but I caught the wink meant for me. Merger? Or another "meeting" with his slutty PA?

Mom set a plate in front of me, kissing my forehead. "Eat up. And Richard, don't work too late. We have that dinner reservation tomorrow night."

He nodded, but as she turned to the sink, his hand brushed my knee under the table, sending a jolt straight to my core. "I'll try, dear," he said to her, but his fingers traced higher, teasing the edge of my panties. I bit into my toast to stifle a gasp, my pussy clenching at the risk. Mom was right there, washing dishes, chatting about groceries. If she turned...

"Tell me about the merger, Daddy," I said innocently, spreading my legs a fraction wider. His finger slipped under the fabric, dipping into my wetness. "Is Emily helping with it?"

Mom laughed. "Oh, his PA? She's a lifesaver, isn't she, Richard?"

He smirked, his thumb circling my clit slowly. "Yeah, she's useful. But I handle the important stuff myself." To me, under his breath as Mom rummaged in a cabinet, "So wet already, baby girl. Thinking about last night?"

I nodded subtly, my cheeks flushing. "Can't stop," I whispered back. "Your cock felt so good."

Mom turned then, and he withdrew his hand smoothly, licking his finger discreetly as he stood. "Gotta run. See you ladies later." He kissed Mom on the cheek, then me lingering a second too long, his breath hot on my ear. "Be good, Isabella."

As he left, Mom sighed contentedly. "He's such a good man. I'm lucky."

Yeah, lucky, I thought, my jealousy flaring anew. But not for long. I excused myself to my room, locking the door to touch myself, imagining his cock pounding me while Mom faded away in the background. My fingers plunged into my pussy, wet and slick, but it wasn't enough. I needed him.

That afternoon, I drove to the auto parts store, heart pounding. The antifreeze was easy to find blue liquid in a jug, labeled for engines but perfect for my plan. I paid cash, no trace, and hid it in my trunk. Back home, Mom was napping, her creamer bottle half-full in the fridge. It would be so simple: pour some in, shake it up. But not yet. I needed to test the waters, see how Daddy reacted to the idea of us alone.

Evening came, and Mom announced she was heading to her yoga class. "Won't be back till nine. You two behave!" she teased, grabbing her mat.

The door clicked shut, and I found Daddy in his study, typing on his laptop. I leaned against the doorframe, my sundress short and flirty. "Alone at last," I purred.

He looked up, eyes darkening. "Isabella, your mom's barely out the driveway."

"But she's gone," I countered, sauntering over and perching on his desk. My legs parted just enough to give him a view. "And I'm so wet for you, Daddy. Touch me."

He groaned, his hands gripping my thighs. "You're insatiable. What if she forgot something?"

"Then we'd hear the car," I said, pulling his head toward my chest. "Come on, tell me about your day. Did you really fire Emily?"

He hesitated, his fingers inching up. "Not fire, exactly. Reassigned her. But it's over."

"Liar," I teased, though anger bubbled. "Prove it. Call her right now, on speaker. Tell her it's done."

His eyes widened. "Now? Baby, that's—"

"Do it," I demanded, grinding against his hand as he slipped fingers inside my panties. "Or I won't let you fuck me."

He cursed under his breath but pulled out his phone, dialing. It rang twice before Emily answered, her voice sultry. "Hey, boss. Miss me already?"

"Emily, listen," he said, his free hand fingering my pussy slowly, making me bite my lip to stay quiet. "What happened between us it's over. For good."

There was a pause. "What? Richard, come on. Last week you said—"

"I know what I said," he interrupted, thrusting his fingers deeper as I moaned softly. "But it's done. Don't call me like this anymore."

She huffed. "Is this about your wife? Or that stepdaughter of yours? I see how you look at her."

My blood ran cold, but Daddy's eyes met mine, fierce. "None of your business. Goodbye, Emily." He hung up, tossing the phone aside. "Satisfied?"

"Almost," I breathed, hopping off the desk and dropping to my knees. "Now let me suck your cock as a reward."

He unzipped quickly, his thick shaft springing free. I took him in my mouth, swirling my tongue around the head, tasting the pre-cum. "Fuck, Isabella," he groaned, his hand in my hair. "Your mouth is heaven."

I bobbed deeper, gagging slightly but loving it. "Better than her?" I asked, pulling back to stroke him.

"Way better," he assured, guiding me back down. "She was sloppy. You're perfect."

We moved to the couch after, him eating my pussy until I came on his face, screaming since Mom wasn't home. Then he flipped me over, slamming into me from behind. "This pussy is mine," he grunted with each thrust. "No one else's."

"Yours, Daddy," I panted, my mind racing. "What if... what if Mom wasn't around? We could do this all the time."

He slowed, still buried deep. "What do you mean?"

I pushed back against him. "Just hypothetically. If she... passed away. Would you marry me? Make me your wife?"

He chuckled, resuming his pace. "Dark thoughts, baby. But yeah, in a heartbeat. You'd be all mine."

The words fueled my orgasm, my pussy clenching around his cock as I came hard. He followed, filling me up. We lay there, tangled, talking softly.

"Tell me more," I urged, tracing his chest. "What would our life be like without her?"

He stroked my hair. "No more sneaking. I'd fuck you in every room. Wake up to your wet pussy every morning."

I smiled, but inside, the plan solidified. "Sounds perfect."

Mom came home later, none the wiser. That night, as Daddy slipped into my room after she fell asleep, we whispered more fantasies. "Imagine poisoning her," I joked lightly, testing. "Something slow."

He laughed, his cock hardening against me. "You're twisted, Isabella. But hot."

"Would you stop me?" I asked, guiding his hand to my pussy.

"No," he admitted, fingering me. "If it meant having you forever..."

We fucked quietly then, his words echoing. He wouldn't stop me. Good.

The next day, I poured the antifreeze into her creamer while she showered. Just a little. Enough to start. She drank it with her coffee, smiling. "Tastes sweeter today," she commented.

I hid my smirk. "Maybe it's love, Mom."

By evening, she complained of a headache. Daddy fussed over her, but his eyes met mine knowing? No, just lust.

That midnight, he came to me. "Your mom's out with meds. Now, tell me what you did."

I feigned innocence. "Nothing."

He pinned me down, his cock teasing my entrance. "Liar. I saw the bottle in your car. Antifreeze?"

My heart raced, but I spread wider. "For us, Daddy."

He thrust in hard. "Fuck, that's dangerous. But... exciting." We talked through the fuck, him admitting the thrill, me detailing the plan. His cock swelled at the details, pounding my wet pussy until we both came.
