Chapter 66 - Younger Sister Is Also A Very Naughty Girl

Just as I finally managed to tear myself away from the boring numbers on my phone and found an app where I could watch highlights of the soccer games I’d missed, my sister suddenly put her little hand where she wasn’t supposed to.

(Phoebe, what are you... Is she still asleep?)

I had to shift over a little so my sister could lie down more comfortably on the seat of Mom’s car.

She rested her head on my athletic thighs, bent both legs, and tucked them against her butt with her knees up, then moved her phone to her two gorgeous breasts and continued watching her entertainment videos... until she fell asleep.

Sohen noticed this when my sister’s hands suddenly stopped holding the phone and it fell onto her big balloons.

(Phoebe, your boobs are huge... You’re definitely related to Runo and Karin, haha.)

My sister couldn’t find a comfortable position after she fell asleep and unconsciously turned from side to side several times, trying to find that perfect spot, which is why her phone almost fell down, but I caught it in time.

(You’re such a klutz, Phoebe... Phew... I’ll put the phone back as soon as she wakes up.)

At first, she lay on the side where the back of Karin and Runo’s seats were, but something subconsciously bothered her, so this time she turned in the opposite direction.

She liked this side better and didn’t move anymore, but there was a certain problem that could... only get worse from here on out.

The thing is, once she finally found a comfortable spot for herself, my sister moved her head a little forward, closer to my groin, and moved it a few times, teasing what was inside my shorts.

(Good thing I’m... "empty" right now)

Before setting off on the trip, Sohen jerked off a few more times because he had a feeling there might be problems if he didn’t, and in the end, that’s exactly what happened. But he was calm and felt free from any signs of sexual arousal; however, the young man knew himself very well and was sure that this wouldn’t happen all the time.

Phoebe slept peacefully until her hand landed on my sensitive spot and gently squeezed my cock, which slowly began to respond.

- (Me). "Phoebe, what are you doing?"

- (Phoebe). "..."

She didn’t answer, since she was still asleep, and Sohen could see that because her face was right there and her eyes were closed.

- (Me). "Phoebe? Wake up..."

- (Phoebe). "..."

Again, no response.

Then Sohen decided to look forward at the front seats of the car, and luckily, no one saw what Phoebe was doing right now.

Karin was still asleep, and Runo was listening to her music with obvious enjoyment, singing along to a song, opening her mouth without actually singing the words out loud.

Sohen turned his attention back to his sister and noticed some changes.

Her head began to move forward very slowly, closer to the cock, which—even after he’d come for the sixth time in less than half a day—had started to form a small tent in his shorts that was only growing.

A moment later, her nose was just a few centimeters from the cock.

(Is she really asleep? What is she subconsciously thinking about?)

Her plump lips began to part, and a pale pink, cute tongue began to emerge, wanting to be set free.

- (Phoebe). "Ouch! What?"

- (Me). "Phoebe is being naughty, sleeping on her brother’s thighs."

- (Phoebe). "???"

Anyway, I didn’t let her continue this little unconscious show she’d put on for me, and with my right hand I gently pinched my sister’s cheek, which finally woke her up.

Looking at me, Phoebe tried to figure out what had just happened, and after a moment, as if she’d found a logical answer, she sat up and apologized to me.

- (Phoebe). "I think I did something wrong. Is everything okay?"

- (Me). My sweet sister had been a little naughty, but aside from some minor inconveniences, everything was fine. By the way, be careful with your phone. A little more and you would’ve had to take it in for repairs."

Sohen didn’t know what she was thinking at that moment, but to avoid any awkwardness between them, he decided to keep quiet about the fact that she’d given him a little massage in the groin area, and luckily, by the time she started to realize what was going on, his dick had already calmed down.

- (Phoebe). "Oh! Thanks for catching it before it fell. There are a lot of important files on it, and it would be a shame if it stopped working because of my mistake."

(Like, for example, a photo of my dick and your ahegao face, but I’m not going to tell you that...)

- (Me). "It’s okay. Then, with your permission, I want to watch one of the highlights from the last soccer game. You can lie down again however you like, or..."

- (Phoebe). "Well then, make me a pillow out of your muscular thighs, hehe..."

- (Me). "Ha-ha. Okay."

Just a few minutes later, we settled back into the same position as before, but this time Phoebe decided to lie down and rest right away.

Her eyes slowly closed shortly after, and I, in turn, continued watching my favorite soccer.

About twenty minutes passed, and during that time I watched one highlight reel and was ready to watch the next, but suddenly Phoebe started moving around again.

Her hand ended up where it shouldn’t be and began teasing that sensitive spot again.

- (Me). "Phoebe?"

- (Phoebe). "Sorry, bro. That... thing of yours is kind of getting in the way of my relaxation. So I..."

- (Me). "Phoebe..."

- (Phoebe). "Oops! I think it’s starting to grow, big brother."

Phoebe kept doing the wrong things.

- (Phoebe). "My step brother thing is pretty big and aggressive... You were so naughty when you put it on my shoulder and slapped my face with it...

- (Me). "Phoebe... Mom and Grandma..."

- (Phoebe). "They’re wearing headphones, so no one will see us..."

(Shit! I think I know what’s about to happen...)

- (Phoebe). "This thing... it reacts so fast when my hand squeezes that spot..."

I quickly glanced at the front seats of the car and saw that Mom and Grandma still weren’t reacting to what was happening right now.

(Please don’t look back!...)

Phoebe kept pushing me toward the forbidden.

- (Phoebe). "This thing... probably needs to relax. What do you think, big brother? Your naughty little sister doesn’t want her big brother to feel uncomfortable, so..."

This cute girl looked me in the eyes with a mischievous smile that I’d only seen on the day she secretly jerked off my dick.

My cock quickly grew hard, and she, noticing the change, looked down at it and bit her lip seductively.

- (Phoebe). "Sohen... forgive your naughty little sister."

- (Me). "Phoebe, we can’t do this in the car!... Shit!!!.."

The fingers of my sister’s right hand quickly hooked onto the very top of my athletic shorts in the center and, in one swift motion, pulled them down along with my underwear, while her left hand slipped... down to my dick and grabbed it.

- (Phoebe). "My brother’s dick♡♡♡... It’s so big that it’s hard to even wrap both hands around it... Hah♡... This trip is going to be the best of my life♡♡♡..."

With one aggressive movement of my sister’s right hand, my cock and balls were completely exposed.

- (Phoebe). "My little brother’s thing... The best♡♡♡..."

Succumbing to an unexpected surge of lust, my sister slowly began to stroke my cock, and I myself was in a highly emotional state from the most extreme escapade of my life, and unfortunately... I began to lose control to my own desires.
