Mom Interrupted Mastrubation

Actually, I accepted my reality. It's fun to masturbate if I do once a day. It's good, and I don't have a problem.

I also got my sister a panty, so instead of a tissue, I can use a panty. Moreover, knowing my older sister knew this, and she seemed happy with it, made it even more enjoyable, no matter how much I denied it in front of her.

So, again, I received panties from my older sister today.

These panties are good, soft, and look beautiful. So, I think for a long time, I'm going to use my older sister's panty as my masturbation tool.

Today's panties color is light blue. They were neat panties with no special patterns and were a bit thorough.

I guess my sister only wears sexy panties.

I took off my pants and lay down on the bed.

Since it's kind of become a habit, whenever I lay down with my sister's panty and pants down, my cock gets erect in just two seconds.

Usually, I warp her panty around my cock and stroke my cock, but today I got an order from my sister.

"When you masturbate, you should watch my videos."

Now, I enjoyed masturbation, and i even did many times before my older sister started giving me panty. I fantasies about my older sister before but never once in my life I masturbate while watching my older sister photo or vidoes.

Because it felt like she was watching me and judging me. That's why I never tried such a thing before, and even I now feel kind of embarrassed.

However, my older sister ordered me, and there was a small part of my heart that wanted to do this. So there is no need to think about anything else.

I go to a video site on my smartphone and search for my sister's name.

Among the searched videos, I chose the one that appeared at the top.

It was a video titled 'Amara, the best tennis player's highlights'

The thumbnail shows my sister wearing a T-shirt and skirt. Under the skirt were tight black pants that ended around her ankles.

The video was edited with highlights of my sister swinging.

Occasionally, there were scenes where she squatted or bent down to pick up a ball.

Since she was wearing long, tight pants, her panties wouldn't be visible even if she was wearing a short skirt.

However, her body and legs were perfectly outlined, which was beautiful. It was obvious what the video producer intended by including such a scene.

And just as the creator intended, I started masturbating while watching that.

I masturbate using my sister's panties while watching a video of her.

At first few seconds, I did feel bad, but soon pleasure ran through my body, which made me enjoyable, and I forgot about my bad feelings.

When I was almost on the verge of ejaculation, I heard a knock on my door.

I stopped moving. At the same time, I almost took my breath away. 

Who is it? Is this my older sister?

If it were my older sister, then did she know, and she came at the right time on purpose to surprise me?

"Rye. Are you sleeping?"

But what I heard on the other side of the door was not my sister's, but my mother's voice.
