Boys will be boys

I woke up the next morning. Yesterday was great, but watching my sister make out with Amber only made me realize how much further I wanted to go.

It seems that Amber has since been long gone, and I hear a familiar rhythmic voice drone away in another room.

I walk into the lab and it seems that Diana is trying to get some last minute studying for some presentation she has to give.

She is sitting there like always. Despite being mindless at the moment, she is making the cutest sleeping face.

I head over to the terminal and type the following:

Whenever you see your brother, it’s common etiquette to greet him with a tight hug and passionate kiss on the lips.

The machine processes the data. Eager to test this out, I pause the program and watch Diana as she begins to stir.

She lets out a big yawn and blinks herself awake.

“What’s up bro. Why’d you pause the fast learning machine. I wasn’t done yet,” she says as she gets up with a slight jiggle in her thicker regions.

“Just wanted to say good morning,” I say as she takes a step towards me and pulls me into a bear hug.

Her meaty tits mush into my chest. They feel like clouds pressing into me.

Knowing what comes next, I close my eyes and brace my lips. Not to my surprise, I feel her soft lips meet mine for a slow kiss. She seems to return the amount of passion I give back. I speed up, so does she. I bite her lips, she bites mine. I stick my tongue in her mouth, she meets me in the middle. Our tongues dance around each other, our saliva swapping places and mixing into one.

I grab her head and run my hands through her soft black hair. They reach barely below her shoulders, but the look fits her. I pull out a Bobby pin that has been holding her hair in a neat, cute style. Her hair falls into a mess, giving a wild looking fashion to her.

Without thinking, I reach my hands to touch her vanilla soft ass. At the same time, I press my erection into her, leaving a squirt of precum on her thigh.

Immediately, she opens her eye and pushes me away.

“Ew, do you have a boner?” she says, clearly grossed out.

I realize my mistake as she wipes her leg with her hand, only succeeding in spreading my cum across her hands and thigh.

“Oh sorry, it’s morning wood,” I say, knowing it’s a lame excuse.

“Okay fine that’s okay I guess. But please just watch out where you put that thing. I don’t want your boner or sperm on my when we make out or cuddle,” she says.

For now, I think.

“Okay okay. My mistake, I didn’t even notice I had one,” I say sheepishly.

Diana’s lack of awareness to this situation is kind of cute.

“Alright, sorry for overreacting,” she responds, “but can you get going? I need to finish studying.”

She makes this too easy.

I say bye and close the door behind me. I stop right outside the door and begin to listen. It doesn’t take too long for the robotic voice to return, to which I promptly renter the room.

“Did ya miss me?” I asked to the basically empty room. I chuckled to myself. That’s just show biz I guess.

I head over to the terminal and type:

Boys have natural urges, so if Tommy has a boner, that’s okay because boys will be boys.

In fact, Tommy’s erection is the most beautiful boner you have ever seen, so you often try to sneak looks at it.

Realizing it is getting late, I head to work.

—————————————————-

I come home early to a silent home. I look around and I cannot seem to find Diana. Until I notice a soft sound, that is. I trace it back to Diana’s old room and make out heavy breathing—maybe even some light moans?

I gently open the door and see Diana masturbating on her old bed. She seems to be watching what looks to be a homemade porno on her laptop.

Wait a second, I recognize the girl in the video. It’s Amber, and she seems to be recording herself blowing another guy in a public bathroom.

I realize this is my time to strike. I open the door, making a point to jut out my dick, almost like I’m parading my erection.

“Hey what’s up sis,” I say boldly.

She quickly removes her hand from her crotch and closes her legs. I can see the stringy ropes of liquid around her fingers. Her face blushes bright red as she frantically turns off her laptop.

“Hey Tommy!” she says with a dry smile on her face. “I didn’t know you would be home so early!”

I see her get caught on her words as she notices my proud erection. She seems to relax her legs a little, no longer hardly pressing them together.

Despite her best efforts, I can see the wet spots on her bed. I move closer, making a point to have my penis directly in front of her face. She’s trying her hardest to maintain eye contact.

What a view, your sister sitting in a puddle of her own cum, staring up at you, with your erect penis inches from her face.

“I got off early,” I say jokingly, “why are you in here. What have you been up to?”

“Oh, I just came to use my desk and work. Yknow, the usual,” she says, obviously still embarrassed.

This is interesting. It seems that my command only influenced her perception on male arousal, which I guess makes sense.

I say nothing while I stare at her tits. She noticed my gaze and takes the chance to grab an eye full of my fat cock.

Realizing she hasn’t greeted me yet, I pull her up and into a big hug. I make a point to press my dick into her thighs. I mark her as mine with a trail of precum. She says no words as she pulls me in for a passionate kiss. This time, she starts it fast, sticking her tongue as far as she can down my throat.

Though she still thinks of me as a brother, there is only so much she can do to stop herself from being wet. She pulls away, a string of spit connecting you to her. She breaks it, making sure to use her finger to stuff her half of it back into her mouth.

“Im hungry, lets eat,” she says, as if nothing happened.

Oh, how much I want to eat.
