Cocksucker does much more than just suck your dick

 1. It also worships your manhood. A cocksucker understands the enormous privilege it has when you allow him to suck your cock.
the more you give it to it the hungrier it gets and the better it will perform, devoting itself exclusively to your total pleasure.

2, A good cocksucker makes your dick the center of the world while it's on his knees. That's a big turn-on for most men.

3. You don't have to feel guilty about using a cocksucker instead of having mutual sex with it.
A cocksucker wants to be used, wants to make it all about you and your pleasure, your cock, your masculinity.
It's on its knees to serve you, its feeder. A cocksucker doesn't expect or want reciprocation.
It is happy to go after it has served you.

4. A cocksucker allows you to express your dominance, as the cocksucker necessarily submits to you and allows itself to be used.
Most men love to be dominant, and you can't get much more dominant over another than by using it for your
sexual pleasure and sticking your dick in its mouth. Having your cock worshipped by another, on its knees, and seeing
the hunger and need in its eyes, amplifies your power and reinforces your dominance. Over time you become more superior.

5. A cocksucker will allow your superiority to inform and guide its worship.
In turn this will enable you to realize, if you didn't already, that you can get a cocksucker to serve
you any way you want and you don't need to hold back.

6. Cocksuckers expect to be used this way. Its how they are and what they need to be fulfilled.
This is why men use cocksuckers. Or could if they wanted to.
