Chapter 3

Sienna’s POV

When Grant’s voice dropped right against my ear, it carried a slow, undeniable force that offered absolutely zero room for refusal.

I froze entirely.

The paralyzing shame of being caught red-handed crashed over me like a bucket of ice water. My limbs went completely weak, and my breathing derailed into frantic, shallow gasps.

My boyfriend was sitting right in the fucking driver’s seat.

And I had just been grinding myself against his father's lap.

The pure humiliation of it slammed into me. My face burned with a stinging heat, and my heart hammered so violently I thought it might burst through my ribs.

What the hell is wrong with me?

I just wanted to curl into a tiny ball and pretend none of this had ever happened.

He didn’t say another word right away. Instead, he simply shifted his knees, pressing up with a subtle, deliberate pressure that forced my center of gravity right back down onto him.

"Since you're already dripping wet, don't bother pretending now."

Grant’s hand slid completely beneath the hem of my skirt.

He didn't rush straight for the most sensitive spot. Instead, his calloused thumb settled on the delicate skin of my inner thigh, tracing slow, agonizing circles over the overheated flesh.

Every single pass of his thumb expertly bypassed my core, yet it constantly teased out a deeper, excruciating tingle that curled my toes.

I bit down hard on my lower lip, but a soft, broken pant still slipped through.

My underwear was already soaked through, clinging stickily to my skin. With every microscopic shift of his hand, it created a faint, wet friction.

My breasts rose and fell rapidly with my erratic breathing, straining visibly against the fabric of my dress.

This was too much.

This is so fucked up.

Yet, traitorously, my body was melting for him.

Grant’s low, gravelly timbre and those rough, experienced hands possessed a twisted magic. It made me terrified of him, but simultaneously desperate to inch closer.

Sensing my reaction, his free hand suddenly wrapped around the back of my neck.

He forced my head to tilt back, pressing my face firmly into the crook of his shoulder. The tall collar of his tactical jacket perfectly concealed the lower half of my face.

"Shut your mouth. Make one more sound, and Kevin is going to turn around and see his girlfriend acting like a little slut on my lap."

His hot breath fanned against the sensitive skin behind my ear, laced with a very clear, dark warning.

I had no choice but to muffle every single whimper into the fabric of his jacket, my body swaying slightly with every subtle, upward thrust of his knees.

Shame burned so hot I could barely think, but my hips still followed every small push of his knee.

I had no idea how much time passed.

Finally, the hand that had been tormenting my inner thigh moved up. Right over my soaked cotton panties, he pressed his palm firmly against my wettest, softest part.

The pressure wasn’t bruising, but it was enough to send a violent, crippling wave of pleasure shooting straight up my spine.

I jerked, my vision flashing white. I almost screamed.

But his hand tightened on the back of my neck, ruthlessly choking the sound right out of my throat.

"Hold it in. It's not your turn to scream yet."

He didn't plunge his fingers inside me. He simply used the heel of his hand to grind and press against me, alternating between slow torture and heavy friction.

The pleasure was stretched out endlessly, washing over me in relentless, agonizing waves, yet constantly denying me the final release.

I was trembling violently against his thighs, my sanity being ground into absolute dust.

Kevin is right there. Less than three feet away. And I’m soaking through my underwear on his dad’s lap.

Kevin was completely focused on the treacherous road ahead, occasionally tossing out a complaint about the terrain.

Everything happening in the backseat was perfectly masked by the roar of the engine and the howling mountain wind.

Just as I was about to completely shatter from the prolonged, edge-riding torture, Grant suddenly stopped.

"That's a bit too biased in your favor, Sienna."

I blinked my eyes open in a daze, my voice coming out as a raspy whisper. "What...?"

He didn't explain.

He simply tightened the arm locked around my waist and thrust upward—hard.

The scorching, rock-hard length of him slammed directly into the deepest cleft of my ass through his slacks. The sheer force of it knocked me forward.

The presence of his erection was terrifyingly vivid. It was brutally hot and rigid, feeling like it had already reached its absolute breaking point.

I ground my teeth, reaching up to pull the jacket collar down just an inch away from my mouth.

I spoke in a whisper so faint it was barely a breath.

"... If it stays pressing against you like this, it’s still hours until we reach the cabin. I've heard that if a man holds it in for too long, it's bad for him... it'll hurt."

Grant’s movements halted completely.

He lowered his head slightly, his gaze dropping to my face. His eyes were so impossibly dark they looked like they could swallow me whole.

"Oh? And how exactly would you know that?"

"I just... heard about it before." My face was burning so hot I thought I might catch fire, but I forced the words out anyway. "And your pants are so tight... keeping it pressed like that might leave a mark... you, you should probably take it out and handle it first."

He let out a low, dark chuckle. The deep vibration rumbled directly into my spine.

"Alright."

The rough pads of his fingers gripped my chin, forcing me to turn my head and look him dead in the eye.

The predatory hunger in his gaze was completely unmasked.

"Then you do it. Take it out for me. Right now."
