Chapter 3: Sinful Desires (3)

"Stop it!" A small voice yelled at the back of my head, yet I continued.

I didn't know how to stop myself from rubbing the thick, throbbing head of my cock against her pussy.

I didn't know how to stop myself from massaging her soft, right boob with my left hand.

Instead, I continued. 

Her wetness seeped through her panties as she stirred, breathing and moaning harder. She let out a soft moan and rolled her head on my shoulder, her breathing was now directly on my neck. 

I froze. 

What if she was only pretending to be asleep? What if she knew exactly what was going on? I could tell from her heavy breathing that she was so fucking aroused by what I was doing to her.

My hands remained in the same position as she panted on my shoulders. While my left hand cupped her boobs through her thin dress, my right hand still held my cock. 

I dug hard on my lower lip as I gently released my cock. Desire flicked through me as I waited for a reaction from her.  

After a couple of seconds she moved slightly, and I gently rubbed my finger over her pussy, feeling the moisture. 

She was soaking wet! I had gotten her aroused, even in her sleep. Now, how was I supposed to explain this situation if she jerked awake? I had no idea.

 How would she even react to seeing my finger on her pussy, and my other hand over one of her boobs?

She would definitely freak out. I waited until her breathing slowed down before my left hand reached through the top of her dress and gently cupped her juicy tit.

Oh God!

Having to hold her breast bare felt so fucking good! Her nipple was hard as I gently caressed her boob. Suddenly, my cock twitched. 

It was against the back of my hand which was still rubbing her pussy. Then, I started to trace the outline of her slit over her panties. She had gotten even more wet, and I could feel it through the fabric of her panties. 

I gritted my teeth and slowly spread my legs apart, causing her legs to also open some more. 

A smile spread across my face as I realized what had just happened. I had more access to her now. Without thinking, I pulled her panties to the side, using a single finger and caressed her clit with the head of my dick.

She was dripping.

Jennie moaned again, this time it was louder. Her breathing started to quicken again. 

I paused for a moment to think about everything that was happening. 

Henry, what the hell are you doing? I asked myself silently. 

My beautiful wife was seated next to me, completely hidden from view and here I was, groping my innocent sister in-law who was sleeping.

I was even inches away from fucking her as my cock twitched at the opening of her pussy. 

Was I willing to take the risk of going a bit further with this? I didn't know.

All I knew was that my cock could no longer hold back from inviting itself into Jennie's pussy!

I parted her pussy lips with my fingers and pressed the tip of my cock against her wet entrance. With how wet it was, I was so stressed that it would slide in, with the slightest  nudge. 

I squeezed her boobs a bit, and massaged her slit for a few more seconds.

"Fuck her!" A loud voice teased at the back of my head. "Push it just a little bit into her pussy."

My mind clouded as I decided to take my own advice. Then, I adjusted my legs, and gave my cock a nudge until her pussy lips. 

In an instant, Jennie's body tightened against me. 

She threw her head over her shoulder and her eyes met mine. 

My mouth turned dry as I realized that she was wide awake. 

"Henry, Wh-what are....you... you doing??" She asked. 

Her legs clamped shut as she shoved my hands off, struggling to jump off my legs. 

As a result of her forward motion, my cock which throbbed at her wet entrance, slid a couple of inches into her pussy. 

"Oh my God!" She shrieked, looking at me with shock. 

It was a good thing that the music was loud and Ciara couldn't hear her sister's shaky voice. 

"Listen, Jennie" I blurted, feeling stupid "I am so sorry that...." It was hard for me to focus on what I was saying because I was trying to stop myself from thrusting my cock all the way into her pussy. 

Jennie continued to struggle.  

This wasn't helping matters at all. Rather, it only excited my cock which was pulsing at her pussy. 

I placed a firm hand on her smooth legs and gently spread them back open again. 

"Henry. Please .... you're married to my sister. What the hell are you.... doing?"

"Jennie, you're so hot, and I never wanted this to happen," I said with a strain in my Voice , too caught up to think clearly "Stop moving, please. You're riling me up." 

"Henry!" Jennie shrieked louder as she attempted to raise her butt up. With that one move, my cock flinched even deeper into her sweet pussy. 

"Are you two okay?" Ciara asked with a loud voice. "Should I turn off the music or something?"

Jennie and I stiffened. 

I held her firmly against me, squeezing her. Her dress straps had fallen off during the struggle, and her boobs were now exposed. Jennie met my gaze as I pleaded with my eyes, begging her to remain silent. 

She looked at me, obviously too confused to say anything. She probably didn't know what to do, especially after finding out that her sister's husband had put her in this position. I had watched her grow since she was 16 and now she was 20. 

But now, she looked at my hand which cupped her boob and my thick dick which was already halfway up her vagina. 

If she said anything to her sister about what was going on, then my marriage with Ciara would be over. Ciara would never forgive me for this!

Moments passed and Jennie started to cough. "I'm so sorry, Ciara.." She said with a loud voice.

"Are you okay?" Ciara asked. The volume of the music on the radio went down and silence enveloped the car. "Jennie?"

My chest tightened with fear. This was it. Jennie was definitely going to expose me. Damn it!

Jennie looked at me one more time, and looked away, out of the car, "I had a bad dream, Ciara, and Henry woke me up, just as I was freaking out."

Relief washed over me. 

"Ah, okay. Henry, aren't you exhausted?" Ciara asked, still driving, "You two should try to get some sleep before our next stop."

Jennie looked back at me, and I felt like leaning close to kiss her out of gratitude. 

"Yes, Babe. I was only trying to get... comfortable. I'll try to sleep as soon as possible. I need it" I repatord looking at Jennie. 

Ciara turned up the music on the radio and I let out a long sigh. Jennie sobbed quietly, as she squeezed my arms. 

"Hey, Love" I moaned next to her ear, "It's okay "

"I've never done this before. I've never had sex before...and you're so damn big. Can we stop please?"

I wasn't surprised that she was a virgin because her pussy was so tight, firmly wrapping around my cock. Being a virgin at 20 was quite impressive, I reasoned.

Not wanting to give her a chance to change her mind, I planted a soft, wet kiss on the side of her neck and whispered. "Jennie, thank you for not telling Ciara anything. You're so fucking beautiful, Jen. Please, let me push all the way in. Just once, and then, I'll pull my dick out. Is that okay?"

My voice was hoarse and I was sure that there was a wild look on my eyes. 

It was so hard to wait for a response from her because my cock felt like it would explode at any motion.
