CHAPTER 37: CHAPTER 27: MY SISTER IS MASTURBATING

WHAT THE FUCK?

Why is someone moaning and calling my name at the same time?

Is someone home?

Who?

Mia? Or Helen? Did they take the day off?

"Ah! Mm, OH GOD!"

I quietly approached my old room.

Ever since I went to college and Johnny joined the army, the house only had two women living in it, so they didn’t have to share a bed, and Jesse is now using the room Johnny and I used to share.

Jesse?

Is she home from school?

I slowly reached the doorway and held my breath. The door wasn’t locked; there was a gap.

Through the sunlight, I saw Jesse lying on the bed, legs apart, with her panties hanging on her calves. Her uniform skirt was lifted, revealing smooth skin and fair thighs.

Her left hand was pressing and rubbing hard on her clit. Her fingers moved quickly as her legs began to tremble. Her lower abdomen kept wriggling, as if an itch down there made her unable to control her hips.

Love juices dripped from her vaginal opening, leaving a palm-sized wet spot on the sheets.

The tender opening slightly parted, the fluid wetting the labia. As fingers slid swiftly, there was even some white froth near the entrance.

"Ah, mm, ah! OH GOD!"

Jesse moaned as her fingers kept rubbing her lips. Her uniform shirt was unbuttoned, her bra was pulled up to her collarbone, and two beautiful firm breasts swayed with her movements like two large puddings.

Her right hand squeezed her own breast as Jesse arched her back.

Her body was arched, resembling a bridge.

I knew she was reaching climax.

"Kenny, I want you, I need you. Ah!"

WHAT THE FUCK?

Jesse called my name?

Is she using me as a fantasy for her masturbation?

Is she imagining having sex with me?

Oh my God! Looking at the girl on the bed, I opened my mouth but no words came out; I was a bit scared.

"Ah ah ah!" Jesse screamed, her body started to tremble, her nose reddened, clearly she had climaxed.

Her entire face was like a glistening, flushed apple.

The sheets were soaked with her juices, and her legs continued to tremble uncontrollably, showing she was very sensitive, and the climax came quickly.

Jesse opened her eyes, and our eyes met.

"Fack! Kenny!" Jesse exclaimed, hastily covering her chest, sitting up, her naked body exposed before me.

"MY GOD! What are you doing?" I covered my eyes; that was my sister.

"How long were you watching?" Jesse felt like she had embarrassed herself in a school classroom, like when someone has tissue stuck to their butt and doesn’t realize it, then walks around the room while everyone witnesses the embarrassment.

The shame overwhelmed her.

"Not long, just a little while!"

"How long?" Jesse glared at me angrily, "Why didn’t you knock on the door?"

"You were calling my name just now, so I came to the doorway, and you didn’t close the door."

"So, you saw me climax?"

I spread my hands. "Maybe."

"Maybe? Ahhhhh!" Jesse screamed.

Startled, I backed away from the door and ran to the living room. Picking up the remote, I turned on the TV.

National Geographic Channel.

It’s mating season now.

On the screen, two zebras were getting it on.

Fack!

Switching the channel, there was a man and a woman rolling on the bed.

Fack!

"I was just." A timid voice came from behind.

The girl had buttoned her shirt and came out wearing a skirt.

I was very awkward, and Jesse was too.

She sat on the sofa, keeping half a meter’s distance from me, tucking her legs on the couch, hugging her knees as if she was shy.

"Well, I know you’re an adult now, it’s normal."

I broke the silence.

"You think so?"

"Yes, adults have physical needs, there’s no need to be shy about it."

"Don’t tell anyone else."

"You can trust me."

When I turned to look at Jesse, she was also looking at me.

"You don’t have a girlfriend?"

"No."

"I don’t have a boyfriend either, and I often hear girls at school talk about sex. Every time they ask me, I feel really awkward."

"Why? You’re a charming girl. You shouldn’t feel confused."

"Because I have no experience, and they think I must have many pursuers and should have experience. Every time they ask me, I don’t know how to answer."

"My friends all have boyfriends, they even share who has the bigger dick, who has a better body, who’s better at oral? What position goes in deepest?"

Fack! Hasn’t Helen talked to Jesse about this? I feel like I’m having a mid-life crisis.

Right, Helen herself is a virgin; she can’t guide Jesse.

God, do I have to give my sister a sex-ed lesson?

"Why aren’t you saying anything?" Jesse asked shyly, burying her head in her knees.

I prefer dealing with thugs. I can easily smash their heads in. But facing Jesse?

I don’t know what to do.

"Relationships between men and women are mainly about feelings, that heart-fluttering sensation. Choose a boy you like, but always learn to protect yourself, and remember to take safety measures. Like condoms or birth control pills, don’t let those guys cum inside lightly."

What the fuck am I saying? This is what parents should do. I’m her brother, damn it.

"I don’t even have a boyfriend yet." Jesse said discontentedly.

"You will."

"What does kissing feel like?"

Fack! I know teenagers are curious about the opposite sex and sex itself, that’s puberty. Parents should guide and educate, and some kids are rebellious. Stopping or forbidding them often piques more curiosity.

"It’ll excite you, your mind going blank, creating a craving. As for comfort, that depends on your dopamine levels."
