Two hands keeps them in place and allows you to ram that monster down their tight throat.  You can position their head wherever it feels best on your cock. It may hurt the fag a little, and his throat will definitely be sore for a while, but who really cares, they are here to drain your balls and make your cock feel good. Besides, a little suffering is good for them, right? Reinforces their place in life.
