Chapter 2: Sinful Desires (2)

“So, is everyone set?” Ciara asked loudly from the driver's seat. I could only see the top of her hair from over the large TV between us. 

“Uh..” I paused, “We are alright. Aren't we, Jen?” I asked her, closing the car door. 

Jen coughed, “Yeah, I am.”

Ciara began to drive.

~~~~

Jennie was as light as a feather, and she still felt soft against the hardness of my body, despite being so fit. It seemed as though each time she leaned back, her body melted into mine.

She wore a peach-like fragrance and it felt intoxicating as my nostrils took it in. The car rocked our bodies steadily, and soon she was leaning her head against my shoulder, with her eyes shut. My senses flared as her exposed neck was next to my face. 

Sleep fled from me and I became wide awake. I was suddenly aware of every curve of her body as she rocked against mine. The deep cut neck of her summer dress gave me a slight bore of her cleavage.

It was obvious she didn't even have any bra on because her boobs bounced as the car went over speed bumps, and I could see the outline of her nipples. 

Every ten minutes or so, Jennie would adjust herself, trying to get more comfortable and I felt one thing; the crack of her ass, slightly tracing my cock.

Well, I was sure she never planned to make me feel this way. We didn't even have such a relationship because she regarded me as her older brother. 

How could I ever betray her trust by allowing myself to get horny, just because she was seated on my lap?

I decided that it was best to distract myself and try to get some sleep, but the softness of her body against mine seemed to distract me even more. Each time the car went over a speed bump, a friction occurs between her ass and my laps. 

Slowly, I felt my cock become hard and it pushed upwards, along her ass crack, towards her pussy,  but the raw tension in my gym shorts had a way of preventing my cock from fully pushing into her crack.

 Damn it!

I couldn't continue like this. Something had to distract me from the wild thoughts that were running in my head or else, I would end up crazy before we were even halfway through the trip!

I cleared my throat softly, "Ciara?" I called out to my wife. 

"Oh! Babe " My wife responded from the other side of the car, "Aren't you supposed to be asleep? Is Jennie asleep?"

"News flash!" I groaned, "I can't sleep, I just...need a bit of noise. Turn up the music, please. I can't reach the radio. And yes, Jennie has been sleeping."

"Okay. Great!" Ciara piqued, "If you need to stretch or anything, make sure you wake Jennie up."

I nodded, then I remembered that she couldn't possibly see me. The TV completely blocked her view of the passenger seat. I let out a long sigh as the volume of the music on the radio went up.

Ciara was talking, but I couldn't hear him over the music.  So I simply reached out and lightly placed my hand on her head, giving it a slight pat before pulling away.

"Ok, sounds good, don't be afraid to wake Jessica up if you need to stretch or anything."

My next goal was to focus on the music which boomed in the car, but as I closed my eyes, I only seemed to get even more riled up, as the fast beat of the song made my head foggy, and Jennie's warm ass grinded against my body. 

My eyes tore open and my attention fell on Jennie's thighs. She had such perfectly long, slender legs and I could barely wrap my mind around how her body could be so beautifully perfect. Her thin dress was now riding up on her thighs and I noticed that her cleavage was now deeper because the left strap of her dress had gone off her shoulder. 

I felt like I would explode. 

My cock was almost completely hard as blood pumped through me. The build up of pressure in my shorts was almost making me insane.

"Jennie," I whispered against her soft neck,"Are you awake?"

There was no response besides the heaving of her chest as she took in short breaths. 

Damn it, Man!

This is your sister-in-law! Snap out of this. 

I tried to readjust myself slightly so that my cock wasn't pressed along her pussy as closely as it was before. I dug my teeth until my lower lip, trying to stop myself from grabbing her juicy tits with one hand, hoisting her up and fucking her right here, even though her sister, my wife sat on the other side of the car. 

It was hard. Way too hard to stay in control. 

The body heat, the awkward friction and the pressure built up, and suddenly I couldn't think clearly anymore.

My body began to catch out on its own. 

I shot a wary glance at Ciara again, just to be sure she couldn't see me over the TV which was wedged between our seats. Next, I leaned close to Jennie to make sure that she was fast asleep. I knew she was from her steady breathing motion. 

Fuck.

Her skin was incredibly soft. Without pausing to think, I gently placed  my right hand on her right thigh, and I waited to see whether I would get any reaction from her. 

There was none. 

I continued my risky move. This time, I placed my left arm around her skinny waist and pulled her closely against my body.

Jennie stirred slightly and I stiffened, relaxing the grip I had around her waist. Minutes passed and she slumped against me. Soon, I was softly massaging her flat stomach; slowly rising higher until I got to her underboob. 

Shit. 

My senses left me as my cock became rock hard. I couldn't even think clearly anymore. Jennie was no longer Jennie to me. Rather, she was some freaking hot teenage girl who sat on my lap, half naked. 

I gently inched my other hand up and pressed lightly against her right tit, feeling the soft mound of flesh fill my palm against the thin fabric of her dress.

 She was definitely about the same size as my wife's, but I noticed that Jennie's tits were younger and more firm. 

I snapped my eyes, held my breath and gave her tit a light squeeze. My hard cock twitched just underneath her pussy. 

I had no idea whether I was imagining it, but her spot felt so warm and slightly damp. Raw desire snaked its way through me. 

 My right hand began to slide her dress up as reg minutes went by, and soon I caught her pink panties peeking out. 

It got worse. 

The thick, long bulge of my cock was now visible between her legs, and it pressed hard against the bottom of her wet panties. 

My breathing quickened. 

This was taking a different, more dangerous turn, but did I care? I could barely give any damn about it now. 

My wife was sitting less than two feet away from me, driving, and here I was, shamelessly feeling up her sleeping younger sister. 

I had to figure out how to get my shorts off because the pressure which was fast building up in there was too much to handle. I shot a glance at Jennie again, wrapping my left arm around her waist a second time.

Then, I pushed my legs up, partially raising myself above the seat before I used my right hand to pull down my shorts past my knees.

I let out a gasp, my  erect cock popping out. My hand slid her dress up, fully revealing her panties before I sat us back down on the car seat. With my shaft pressed along her slit, my cock stood erect, pointing forward. 

It felt so damn good, sending a thrill through me. My brain did the quick math; if I made her lean forward, just a little bit, my cock would be right at her pussy.

The only thing which separated my cock from rubbing against her pussy was her thong panties. I swallowed hard.

All I had to do was slid her panties to the side. I drew in a sharp gasp, hesitant. Then, I did something silly. 

I pushed my bare cock towards, gently massaging her pussy with it. Her panties stood as a barrier, yet it felt incredible. My left hand was still on her right boob, gently rubbing it while my right hand massaged the thick head of my cock against her pussy. 

Her wetness seeped through her pussy, and her breathing became harder. 

A soft moan escaped from her throat and I felt my life flash before my eyes. 

Damn it!

She was definitely awake now.
