        self.recording_stream = self.p.open(format=audio_format, channels=channels, rate=rate, input=True,
        print("Connected to Server")

        # start threads
        receive_thread = threading.Thread(target=self.receive_server_data).start()
        send_thread = threading.Thread(target=self.send_data_to_server).start()
    def stop_streaming(self):
        self.streaming = False





        print("finished clean up")

    def receive_server_data(self):
        print("started reciving data.")
        while self.streaming:
                data = self.s.recv(512)
        print("stopped reciving data.")

    def send_data_to_server(self):
        print("started sending data.")
        while self.streaming:
                data = self.recording_stream.read(512)
        print("stopped sending data.")


使用时,首先创建 Client 对象。

client = Client(address[0])

在需要交换数据时调用 start_streaming() 方法。


在需要停止交换数据时调用 stop_streaming() 方法。

  21. Garrett can see what his father is doing, unconsciously his hands moves to his cock. He strokes the length of his tool with his left hand while he teases the blistering red crown with the fingertips of his right hand. The lightning of his cool fingertips sends sparks through every nerve in his body.

  22. “Damn it, son! Damn it! Damn it, you hit the mirror above the sink!” His father shouts as the bullets of cum shoot forth from his son’s cock and hits the adjacent mirror directly in front of the porcelain bathroom thrown.

  23. Exactly a week after, daddy texted me with a different tone saying, “ get your ass ready tonight cause daddy is coming to your place tonight.” He was usually really sweet and nice, I was shot when I got the message. But automatically I said, “ yes daddy!” I guess I am a slutty whore for him right at the beginning as I knew my place where is always going to be inferior.
