A cold feeling came from my fingers.

Ying Sitong raised her eyes like a charming look and sniffed the back of his hand gently.

It's like a kitten.

Xia Yuan was slightly stunned and couldn't help but stretch out his left hand to touch her hair.

But as soon as my hand was stretched out halfway, my right wrist suddenly hurt.

Then Ying Sitong's beautiful eyes flowed, and he raised his right hand to his mouth.

"uh-huh……"

Vampire has two different ways of eating:

First, wrist suction, which can obtain nutrition by sucking venous blood from the hands. This method has a small flow rate and can satisfy cravings, but the satisfaction comes late, like a trickle, which needs to be tasted slowly.

The second is cervical suction, which means sucking the carotid artery. This method has a large amount of gushing, which is refreshing and easy to be full. The disadvantage is that the donor is prone to death.

Ying Sitong suppressed her for a long time, and relied on her strong willpower to not bite Xia Yuan's throat.

The reaction of the sucker is-

One word: cool.

Two words: Beier cool.

Three words: What a fuck.

Why?

There is a similar reason to snake bite. When the blood tribe sucks wrist, they bite holes in the vein through the canine teeth, because this pair of real teeth is hollow, which not only can play the role of sucking, but also injects a special substance into the donor's body.

This substance has no side effects and will make the donor feel abnormal pleasure. This pleasure comes quickly and fiercely, far exceeding all happiness in the world.

From an evolutionary perspective, this is to allow the donor to provide blood more willingly without rebellion and make eating safer.

So in less than half a minute, Xia Yuan fainted from extreme excitement.

"Oops."

Ying Sitong raised her head in horror.

"It seems a bit too much, I accidentally eat too much."
