I see......

Su Xiaoli suddenly realized.

However, after she suddenly realized, the restless little hand rubbed towards Su Mu's lower abdomen.

Her fingertips slid softly, slowly, little by little, through his thin pajamas.

Su Mu only felt that the hairs on his body stood up, he subconsciously held Su Xiaoli's little hand tightly, and asked in a low and hoarse voice, "Don't touch it." ”

"Why?" Su Xiaoli's tone was full of incomprehension.

It was as if she was touching her brother's lower abdomen to see if there was any heat flowing through.

"No why." Su Mu grabbed her hand and put her hand outside the bed, then turned around and turned his back to her and said, "Hurry up and go to bed." ”

“……”

Hmph, don't let her touch it, she just wants to touch it!!

Su Xiaoli pouted unhappily in the darkness, and carefully recalled the plot he had just watched.

It seems that the above said that boys will be more sensitive behind their ears, and when they are sensitive, they will react, but they do not say what the specific reaction is......

Su Xiaoli blinked, feeling that practice still made true knowledge, so she leaned up lightly and leaned silently towards her brother's back.

By the faint moonlight outside the window, she could barely see the outline of his brother.

Su Xiaoli propped up one arm, cautiously leaned next to Su Mu's ear, and then whispered while breathing: "Brother......"

Her warm breath sprayed on his ears, and with a slightly wet, wet sensation, it swept past his ears as if out of nowhere.

A strange feeling passed through Su Mu's heart, but he still turned around and whispered to Su Xiaoli, "What are you doing?" ”

"Don't do it, I'll see if you're asleep ......" Su Xiaoli still leaned next to his ear and whispered.

Her behavior inexplicably made him feel as if a strange feeling was taking root in his heart.

“……”

After Su Mu was silent for a moment, he tried to suppress the strange feeling in his heart, and said in a faint voice: "Fall asleep, you should also go to sleep quickly, don't talk." ”

"Oh......" Su Xiaoli felt a little disappointed.

It seems that the above is all a lie, saying that the back of the ear will be more sensitive, and her brother obviously didn't react at all.

Could it be ......

Is it the way she practices that isn't quite right??

Su Xiaoli tried hard to think about what he did wrong.

Suddenly, a flash of inspiration flashed through her mind.

That's right!! The female protagonist on the male protagonist is not just talking and blowing behind the male protagonist's ear, she also kissed the male protagonist's ear!!

Thinking about it like this, Su Xiaoli instantly had a feeling of opening up the second pulse of Ren and Du.

However, just as she was about to put it into action, in the darkness, Su Mu's deep and gentle voice suddenly sounded: "Xiaoli." ”

"Huh??" Su Xiaoli was stunned for a moment, and subconsciously responded.

"Can't sleep??" Su Mu turned her head and reached out to touch her hairy head.

"Uh...... Hmm......" Su Xiaoli replied in a low voice.

Not only can't she sleep, but the curiosity in her heart is about to explode!?

"What are you thinking??" Su Mu reached out and put his arm around her shoulder, and asked in a low voice.
