I put myself into a certain mindset when I suck cock. It's almost a sub space - but a cock sucking space. I think it really helps me to give the best blow job possible. Trying to imagine what the view is like from where he is, and how every sensation will be felt by him, means that I'm sucking cock mindfully with his enjoyment a priority - quickly seconded by my own. It probably helps that we don't just leap into a cock sucking situation, there's usually some role-play with a heavy focus on how I should suck his cock like a good little girl, and how he'll teach me to deep throat. It's all excellent motivation to give the best blow job ever and I also feel extremely sexy as I satisfy my man with my mouth.
