Forbidden Romance--My son is using his wife to test me.

He sends me photos of her—intimate, revealing. He tells her I’m watching. He tells me she likes it.

And now… she’s at my door, playing her part perfectly. A vision in a low-cut shirt and yoga pants that hide nothing.

She serves me lunch, "accidentally" showing me the lace of her bra. Her every move is a calculated temptation. My son texts me while she’s in the kitchen: “Does she look good today?”

It’s a sick, twisted game. A trap laid by my own flesh and blood.

The worst part? I’m not sure I want to escape.

He’s the puppet master. She’s the willing puppet. And I just sent the one-word text that told them both I’m ready to play.

How far will a son push his father? And how long can a good man resist the one woman he can never have?

Drop a 🔥 if you think Arthur is about to cut the strings.

Now she’s at my door, her body promising everything the photos did.

He lit the match. She is the flame. And I am about to let my entire world burn. 🔥

Wicked Taboo- The Mother I Crave

I woke up in my girlfriend’s brother’s bed to find her mother, Eleanor, between my legs. And what she did next pushed us both over the edge.

Her head was bowed as she licked me with a reverence that made my stomach clench. I was instantly, painfully hard.

But I needed more.

I pulled her up onto the bed, turning her until she was on her knees. I was buried deep inside her when her phone rang, shattering the night.

The screen lit up with a single name: Chase.

Her son.

I didn’t stop. "Answer it," I whispered, the command a dark thrill.

Her hand trembled. "H-hello? Chase?"

His voice was tinny through the speaker. "Mom? I can't sleep. I was thinking of just grabbing an Uber and coming home."

I chose that moment to thrust deep.

"No!" she gasped, too quickly. "No, honey… Mom's… ungh… Mom's fine."

"Mom, are you okay?" Chase asked, his voice laced with suspicion. "You sound… weird."

The second she hung up, she shattered. "You bastard," she sobbed, but her hips arched back against me. "While my son was on the phone… oh god, Finn… don’t stop."

We collapsed in the wreckage. Her eyes were wide with shame and exhilaration.

"Finn," she panted. "I think he knows something's wrong."

What happens when a son's suspicion turns into an investigation? And how long can a secret this explosive stay hidden in his own house?

Wicked Taboo- Tangled Lines

Finn seems to have it all: a loving girlfriend, Chloe, and a best friend who’s like a brother, Chase. But a dark secret binds him to the one person he should never touch: Chase's mother, the elegant and beautiful Eleanor. What starts as a shared secret quickly ignites into a forbidden, high-stakes affair. Every stolen moment and whispered lie pulls Finn deeper into a web of deceit. He is falling for the mother while betraying the son, and as his obsession with Eleanor grows, he risks losing not just his friend and girlfriend, but his entire world. It’s a dangerous game of love, loyalty, and betrayal where one wrong move will leave everyone in ruins.

Wicked Taboo- The Sin ofBreakfast

The morning after crossing the ultimate line with my best friend’s mom, guilt didn't stand a chance against our addiction.

When Chase called to say he wasn't coming home, the elegant Mrs. Hayes dropped her maternal facade completely. What followed was a day of pure, unhinged taboo. From taking her against the kitchen counter while she cooked, to making her worship me under the dining table, we blurred every single boundary. She wasn't his mother anymore; she was entirely mine.

But our forbidden fantasy crashed to a dead halt when my phone buzzed on the coffee table. It was my girlfriend, Chloe.

She was back in town early—and pulling into the driveway in exactly five minutes. 😱🚪

Wicked Taboo- The Second Fall at Dawn

The morning sun exposed exactly what we did in the dark.

Waking up on the living room sofa with Eleanor tangled in the sheets next to me, the reality of what we’d done hit me. We crossed the ultimate, forbidden line—right down the hall from my best friend.

I expected her to be filled with regret. But when she looked up at me with heavy, half-lidded eyes, the tension between us instantly caught fire all over again. The guilt didn't stop us; it only fueled us to go back for seconds.

The teasing is over. We’re officially past the point of no return. 😈🔥

Wicked Taboo-Midnight after drinking

For weeks, my best friend’s mom has been edging me in secret, refusing to let me cross the ultimate line.

But that all changed the night I dragged her son home blackout drunk.

After tossing him into bed, Eleanor told me to crash on their sofa. When she leaned over to hand me a drink, her sheer silk slip left absolutely nothing to the imagination. I snapped. I pulled her down, pinning her to the cushions, and finally took exactly what I’d been craving—right while her son slept down the hall.
