After Gabi arrived, Carla didn’t mention the previous event again. I remained rather silent while Gabi explained how complicated the end of the season was shaping up to be for her team. As we were leaving, Carla said to Gabi at the end of the evening, “Don’t hesitate to ask your big brother. He has plenty of little tricks for the end of the season.”

Far from understanding the underlying meaning, Gabi replied, “Don’t worry, I already do!”

Then Carla hugged me and whispered, “See you Monday, little guy.”

*****

After arriving home and wishing Gabi goodnight, I locked myself in my room. I started to jerk myself off furiously, thinking about what happened. My best friend would never see me the same way again after seeing my little dick spurt without even being touched. After finishing, I reassured myself, thinking she wouldn’t tell anyone. She remains the girl I trust the most despite everything.

The next morning went by normally: breakfast followed by my Sunday running. Since our parents were abroad for a wedding, we decided to take turns cooking until they returned. It was Gabi’s turn, and as usual, she was in her underwear, wearing an apron. With her slightly tanned skin, I couldn’t help but get hard while watching her. During the meal, she told me that James, her boyfriend, would come in the afternoon.

“No problem, I’ll go buy some snacks. The cupboards are almost empty,” I replied.

*****

At the store, in the frozen food aisle, I ran into Sara, a colleague that Carla and I don’t particularly like because of her condescending tone and habit of always bringing the conversation back to herself. Despite her difficult personality, she had a beautiful face with multiple piercings and long black hair. When our eyes met, she felt obliged to greet me, but we left it at that because she didn’t like me either.

*****

Back home, I found the kitchen deserted and started putting away the groceries when I heard strange noises from upstairs. At the top of the stairs, I found Gabi’s bedroom door slightly open, with moaning sounds coming from behind it. I couldn’t help but push it open, knowing what I would see. My little sister, naked, practicing doggystyle with James.

“Damn it, Dean, get out of here!” she shouted when she saw me.

She jumped out of her bed and pushed me out of her room.

“Sorry, Gabi, I shouldn’t have…”

I found myself back at her bedroom door.

*****

A few moments later, I returned to the kitchen to finish putting away the groceries. James came downstairs, looking genuinely embarrassed.

“Really sorry you had to see that, Dean. I hope she won’t be too mad at you.”

Then he put on his shoes and left.

*****

I then went up to my room and sat on my bed. One detail hadn’t escaped me: the size of James’s cock.

It was much, much bigger than mine.

As I took off my pants, I stared at the little worm between my legs. I began to get hard thinking back to what I had just seen.

I put it between my index finger and thumb and started to wank myself.

“Ahem, it must run in the family to forget to close the door, ‘two-finger boy’…”

I stopped abruptly and looked up. There was Gabi, arms crossed, looking amused.

“I came here to scold you, but I think watching your little goon face killed the urge,” she giggled.

“Gabi, get out of here!” I said, my voice unusually high-pitched.

If I hadn’t stopped just now, just two or three more pumps would have been enough to make me explode. My little dick was throbbing with despair.

“Tell me, is that hard? James has a bigger one, even when soft! Considering how much it shakes, you must be close to the end, right?”

That was too much—my little sister’s smirk at the sight of my little dick made me cum hands-free with a groan. “I’m sorry!” I screamed, looking into her eyes.

In a state of shock, Gabi stared at the few dribbles of cum on the floor.

“Did you just…?”

Then she burst out laughing. “I’ve never seen anything so pathetic! And to think you were the man I respected the most just a few hours ago!” She then turned on her heels. “You’d better clean all this up while I make dinner, big brother. I’ll take your turn if you want,” she added, her voice still laughing.

*****

Later, Gabi called me for dinner. We sat in silence for about ten minutes before she broke it.

“So, was it because of James and me that you were horny earlier?”

“Gabi, please, I don’t want to talk about it. I’m sorry about what happened, but let’s just leave it at that.”

“That was quite a show, though. Seeing you cumming in front of your sexy little sister, looking at your babydick. But with such an…unusually small one, you’ve never had any trouble with girls?” she asked curiously.

“You think I’d dare show myself in front of a girl with this?” I replied, ashamed.

Gabi took a few seconds to understand. “You’ve never… Oh, Dean, I’m sorry. I’ve been teasing you this whole time, but I thought you had already… But you know, size doesn’t make the man. I’m sure some girls won’t care about that.”

She seemed genuinely sorry for me; surprisingly, her words comforted me a little.

“So, no one else knows?” she asked.

“Carla found out just yesterday, right before you arrived…and she burst out laughing.”

“Of course, she laughed! It’s not every day you see a little carrot like yours,” she said, half-laughing. “But don’t worry, I’ll help you find a girlfriend, little brother.”

“I’m not sure I want your help with that. And don’t call me like that!”

“He-he, don’t get mad. With your lack of control, you might cream your pants,” my sister teased before bursting into laughter again.

Seeing my lovely, beautiful sister laughing at me only made me hard, and I felt the urge to go to the bathroom.

“Happy fapping seconds, big bro!” she called after me.

*****

My best friend and little sister discovered my little secret in just two days. The next few days were going to be different.
