Her captivating voice!

Like a fatal poison, it almost had control over me.

From head to toe, after admiring every inch of her skin.

I was even more aroused to the extreme.

"Alright, I’m coming now, what kind of moves do you want?"

I panted with heat.

My hands trembled a bit more.

"This place is too small, let me face away from you."

Su Yue said, turning around.

She laid her entire upper body on the door of the fitting room, her back facing me.

Now, her perfectly shaped bottoms displayed an even more tantalizing shape.

But before I could proceed to the next step.

Her phone rang.

Immersed in the amorous atmosphere, we both were startled.

That damned phone!

Su Yue quickly dug it out from her bag, about to turn it off.

But when she saw the caller ID, she was slightly stunned: "It’s my sister!"

A thrill ran through my heart, excitement all over my face: "Then answer it, isn’t that more exciting?"

"Yes, sister certainly doesn’t know that her brother-in-law is having fun with me."

She then answered, on speakerphone, Su Qin’s voice came through.

"Sister, I’ve already arrived at the mall, you’re in the women’s section, right?"

"Ah?" Su Yue was caught off guard: "Sis, how did you know?"

"You always only browse here, right, you should be in the fitting room changing bras."

After Su Qin said this sentence.

Su Yue and I soon heard the click-clack of high heels outside the fitting room door.

This made both of our hearts tighten.

A sense of panic as if our affair was about to be discovered.

"Sister, only this fitting room is closed, it must be you, hurry and open the door, let me see the bra you chose."

Su Qin confidently hung up the phone, then directly knocked a few times on the fitting room door.

"What do we do, if sister sees me having fun alone with brother-in-law, she will definitely be angry."

Su Yue dared not breathe loudly, she could only whisper to me.

"It’s alright, as long as we don’t make a sound, she can’t be sure."

I quickly calmed down.

As long as there’s no sound, Su Qin wouldn’t blindly make assumptions.

Moreover, the fitting room door was locked from the inside, without a key she couldn’t open it.

Su Yue’s eyes lit up: "Brother-in-law is right, just don’t respond with a sound."

"Sister, let’s continue now."

My hands moved, landing directly on her beautiful bottom.

"Mm, ah, brother-in-law, don’t, this is too exciting, sister is just outside the door."

Su Yue hurriedly clenched her teeth.

But a kind of stealth pleasure, multiplied over her body.

Outside was her sister, inside she was naked with her brother-in-law.

This was both absurd and thrilling.

Especially when she had to desperately suppress it, to lower her voice.

But the more suppressed she was, the more sensitive her body became.

The wondrous sensations her nerves touched, became even clearer.

Every finger I ran over her bottom, she could feel, that scorching rub.

She was on the verge of collapse!

Yet in this near-collapse, she was especially joyful.

As I continued to wander, she even started to voluntarily press against my hand, to match my rhythm.

Soon, she was increasingly craving, wanting more.

"Brother-in-law, hurry, uh, I’m almost going crazy, this is so shameful, yet feels so good."

Her exquisite bottom quivered rapidly, with slight twitches, constantly contracting.

I felt my mind was almost flooded with blood, such a marvelous scene was burning away my rationality, wanting to dive in...
