Two main rules of giving a blowjob

Two main rules of giving a blowjob: 1. No matter what technique you choose, the first thing you should do is hide your teeth. Also, remember not to close your teeth with your lips. Firstly, you can hurt yourself, secondly, it doesn't look very attractive. 2. The best blowjob techniques are performed using the lips, tongue, and hands, and all these three parts should become a unified whole, complementing each other, and in some cases even replacing each other.
