CHAPTER THREE: STEPBROTHER’S BET

The Eight-Hour Drive

I am twenty-one. Jake is twenty-three.

We are adults, and we have spent the entire summer proving exactly how adult we can be when no one is watching. But it was wrong. There was nothing wrong with how good my stepbrother drew orgasms out of me. It was funny to think it just started with a bet.

The calendar on my phone has been a countdown of red X’s since June. Every night I crossed off another day, another morning I woke up with his teeth marks on my throat, another afternoon he had me bent over the kitchen island while Mom was at book club. I told myself if we just fucked enough times, if I just let him brand himself inside me often enough, the leaving would not hurt.

It was a lie.

Last night I sat on the edge of his bed and watched him fold T-shirts into boxes to return to college and felt my chest crack open. So this morning, when Rick was swearing at the Tetris puzzle in the back of the SUV and Mom was trying to wedge one last lamp in sideways, I looked at the single empty spot on the back seat and said, clear and bright, “There is no room anywhere else. I will just sit on Jake’s lap. It is only eight hours.”

Mom laughed, called us adorable. Rick shrugged and said problem solved.

Jake’s eyes met mine across the garage and I saw the moment he understood exactly what I was asking for. Eight hours. His cock inside me the entire drive. My goodbye written in sweat and cum and the kind of desperation only he has ever pulled out of me.

The garage door is still rumbling down when I climb over the center console. My sundress is pale yellow, thin cotton, the kind that clings when it gets wet. I chose it on purpose. No bra. No panties. Just the dress and the blanket Mom hands back with a cheerful “in case you get cold.”

Jake watches me settle onto his lap like he already knows every filthy thought in my head. His hands come to rest on my hips the moment the blanket covers us, thumbs stroking the bare skin just under the hem. The car has not even left the driveway yet and I am already soaked.

Rick backs out. Mom turns on her playlist. Some bright pop song fills the space between us.

Jake leans forward, lips brushing the shell of my ear. “Spread your legs a little.”

I do it instantly, parting my thighs until I am open over him. Cool air from the vent kisses my bare pussy and I have to bite the inside of my cheek to keep quiet. The blanket barely moves. From the front seat we must look perfectly innocent.

His right hand slides higher, slow enough that I feel every inch of skin wake up under his palm. When his fingers finally graze my folds I let out a shaky breath that fogs the window.

“Tell me why you are doing this,” he whispers.

“Because I am falling for you,” I answer before I can stop myself. The words are soft, but they feel huge in the quiet car. “Because every day this summer you touched me like I was yours and now you are leaving and I am scared that when you are gone no one will ever touch me the way you do.”

His fingers pause. Then they part me gently, tracing through the wetness I have been carrying since I woke up thinking about this exact moment.

“Lily,” he says, and my name sounds different in his mouth now, rougher, reverent.

The car turns onto the main road. Mom starts singing. Rick taps the steering wheel.

Jake cups me fully, letting the heel of his hand rest against my clit. He does not move yet. He just holds me there, letting me feel how easily I open for him, how ready I am.

“I am scared too,” he says so quietly I almost miss it. “I keep thinking about waking up in that new place and you not being there and it feels wrong.”

I rock forward the tiniest bit, chasing pressure. “Then do not think. Just feel me for the next eight hours. Please.”

His thumb starts the slowest circle around my clit. My spine arches before I can stop it. I press my lips together to keep from moaning.

Mom glances in the rear-view mirror. “You okay back there, honey?”

Jake’s thumb never stops moving. “She is fine,” he answers smoothly. “Just getting comfortable.”

I nod, face burning, and turn my mouth into his neck so she can not see how red I am.

His thumb keeps circling, never quite brushing the peak, just teasing the sensitive skin around it until I am squirming. My thighs are starting to tremble from holding them open.

Inside my head I am screaming: Touch it, please touch it, I need—

He finally flicks the clit once, sharp, and my whole body jerks. A tiny whimper slips out before I can stop it.

Jake’s mouth curves against my hair. “Careful,” he whispers. “That was almost too loud.”

The fear hits me like cold water. If Mom turns around and sees the way I am shaking, if Rick glances back and notices the blanket moving in tiny, suspicious rhythms, everything ends. The summer we stole would be exposed. Our parents would know. The thought should terrify me enough to stop. Instead it makes me wetter, makes my pussy clench around nothing in a way that has Jake hissing softly.

Rick accelerates up the ramp. The sudden surge rocks me back hard against Jake’s chest and the ridge of his cock slides perfectly along my slit. I can not stop the soft, broken sound that escapes.

Mom glances in the rear-view. “Everything okay?”

Jake’s hand slides up my ribcage under the blanket, slow, deliberate, until his palm cups my left breast. My nipple is already a tight, aching point against his palm.

“She is fine,” he answers for me, voice perfectly steady while his thumb starts the slowest circle around my nipple. “Just getting comfortable.”

I nod, swallowing hard, and turn my face into his neck so Mom can not see how wrecked I already am.

His thumb keeps circling, never quite brushing the peak, just teasing the sensitive skin around it until I am squirming. My thighs are starting to tremble from holding them open.

Inside my head I am screaming: Touch it, please touch it, I need—

He finally flicks the nipple once, sharp, and my whole body jerks. A tiny whimper slips out before I can stop it.

Jake’s mouth curves against my hair. “Careful,” he whispers. “That was almost too loud.”

The fear hits me like cold water. If Mom turns around and sees the way I am shaking, if Rick glances back and notices the blanket moving in tiny, suspicious rhythms, everything ends. The summer we stole would be exposed. Our parents would know. The thought should terrify me enough to stop. Instead it makes me wetter, makes my pussy clench around nothing in a way that has Jake hissing softly.

The highway is smooth now, but the vibration of the tires travels straight up through the seat and into my clit where it is trapped against him.

Jake’s left hand joins the right under the blanket. He cups both breasts, squeezing gently, then rolls both nipples at the same time between thumb and forefinger. The pressure is perfect, steady, relentless.

I feel my pussy clench hard.

“Jake,” I breathe, barely audible. “I am already close.”

“I know,” he murmurs. “I can feel you fluttering every time I do this.” He pinches harder, tugs, lets the peaks slip free, then pinches again.

My thighs are shaking so hard the blanket trembles.

“Jake,” I whisper, desperate. “I am falling so hard it hurts. I did not mean to. I swear I did not. But every time you look at me like that I fall a little more.”

He adds a third finger and I have to cover my mouth with my own hand to keep from crying out.

Mum's head lolls against the window. Rick turns the music down a notch.

Jake waits thirty full seconds, then slides his right hand all the way down between my legs. Two fingers part my folds, spreading me open, gliding through the slick. He does not enter me. He just traces, slow, deliberate circles around my clit that make my hips chase his touch.

I am panting against his neck now, little desperate breaths I can not control.

“Tell me what you are thinking,” he whispers.

“That I am going to miss this so much I already want to cry,” I answer, voice muffled against his skin. “That I hate every mile we just put between your bed and mine. That I want you to ruin me so thoroughly I feel you for weeks after you are gone.”

His fingers pause. Then he pushes two inside me in one slow, possessive glide. The stretch is perfect. I bite his shoulder through his T-shirt to muffle the moan.

He curls them, finds that spot instantly, and starts a slow, steady rhythm that matches the thrum of the engine.

My thighs are shaking so hard the blanket trembles.

“Jake, please...”

“Not yet,” he says, and withdraws his fingers completely. I whine at the loss, high and needy.

He brings those fingers to my mouth. “Taste yourself. Taste how much you want this.”

I lick them clean without hesitation, sucking them deep, eyes locked on his in the dim reflection of the window.

He groans softly and I feel his cock jerk against my entrance.

My legs are screaming now. The position is brutal. Jake notices, slides both hands under my thighs and lifts me just enough to readjust, then settles me back down so I am sitting fully impaled, my back to his chest, legs draped over his.

The new angle drives him even deeper. I have to cover my mouth with my own hand to keep from crying out.

He keeps one arm banded around my waist, the other returns to my breasts. This time he is slow, almost tender, tracing circles around my nipples with just his fingertips until they are so sensitive I am shaking.

“Tell me what you feel,” he whispers.

“Like I am going to come just from this,” I answer, voice muffled. “Like I am already ruined and we still have hours left.”

He kisses the side of my neck, soft, open-mouthed. “Good.”

My legs are starting to cramp again. I shift, trying to find a better angle, and the movement drives him deeper. I gasp, loud enough that Rick glances in the rear-view.

“You good back there?”

Jake’s arm tightens around my waist. His free hand slides down, finds my clit, starts slow circles.

“We are fine,” Jake answers, voice steady while his fingers make my hips jerk.

Rick nods, turns back.

I am panting now, the fear of that glance mixing with the pleasure in a way that makes everything sharper. If Rick had looked longer, if he had seen the blanket move, if he had heard the soft, wet sounds under it...

Jake feels me clench around him. “You like that? The risk?”

“Yes,” I whisper. “It makes it better. Scarier.”

He circles faster. “Come for me then. Quietly.”

I do, shaking, biting my own wrist to muffle the moans as my pussy spasms around him.

Rick’s voice breaks the haze. “Next exit, gas and bathroom. Ten minutes.”

Mom wakes up, stretches, yawns. “I need coffee. Lily, want anything?”

Jake’s cock is still buried inside me, pulsing with every heartbeat. I am so close to another orgasm I can taste it.

“I am good,” I manage, voice hoarse.

The car pulls into the farthest pump. Doors open. Cool outside air rushes in. Mom and Rick’s footsteps crunch away across gravel.

The second they disappear inside the convenience store, Jake moves.

Blanket flung aside, hands on my waist, bold now. He lifts me off his cock so fast the sudden emptiness makes me whine, “No, Jake, put it back, please—”

He spins me, pushes me chest-first against the tinted back window. My palms slap the glass. My nipples, raw and swollen from hours of attention, drag across the cold surface and the sting is so perfect I sob, “Yes, right there, please—”

“Hands on the glass,” he growls behind me. “Show me how much you need this goodbye.”

I arch, pushing my ass out, dress rucked up to my waist. “Fuck me hard,” I beg, voice breaking. “Make me feel it for weeks. Please.”

He lines up and slams home in one brutal thrust.

The scream that rips out of me echoes in the empty car. My forehead knocks the glass. Every thrust rocks the SUV on its suspension. He sets a punishing rhythm, one hand in my hair, the other sliding around to rub my clit in rough circles.

“Look out there,” he snarls against my ear. “Any second Mom could walk out and see her perfect little girl getting railed in the back seat.”

The thought alone detonates me. I come screaming his name, pussy spasming so hard I squirt down his thighs and the seat. “Jake, oh God, I am coming! don’t stop—”

He does not. He fucks me through it, drawing it out until I am shaking and crying and begging in broken whispers, “Please come inside me. I need to feel you.”

He slams deep one last time, groans my name against my neck, and I feel him swell and pulse, flooding me with heat, rope after rope until it is dripping down my legs in thick rivers.

We are still panting when headlights sweep the lot. Mom and Rick walking back, coffee cups in hand.

Jake pulls out slow, tucks himself away, smooths my dress down just as the doors open.

Mom slides in, smiling. “Feel better, sweetie?”

I turn, hair wild, lips swollen, his cum already sliding warm down my thighs.

“So much better,” I say, voice wrecked.

Jake meets my eyes in the rear-view mirror and mouths: Two more hours.

I settle back onto his lap, feel him already hard again, and whisper against his jaw, “Make it hurt, Jake. I want to feel you for weeks.”

He smiles, dark and possessive, and the car pulls back onto the highway.

Best goodbye I have ever had.
