Amazing. It's like you are giving someone immense amounts of pleasure selflessly.
You start sucking and the cock is still somewhat soft, and each time you bob your head up and down, it gets harder and harder, and you feel it, so your brain knows that you are making him feel really, really good and that makes you become really aroused yourself.
You hear him grunt and moan with pleasure as your tongue is wrapping around his head, your face is buried in his crotch, his cock is deep in your throat, his balls are on your chin and your nose is stuffed into his pubic area and you are smelling his manly scent. If he has good hygiene, it is not a bad odour at all and it is actually very hot.
You feel your cock leaking precum all over the place, but you have no desire to reach down and touch yourself, your entire mind is blank and your only goal is to make him feel good.
Whether you are doing the movements, or he is thrusting in and out of you, it is amazing. When he is about to cum you will feel his cock almost swell up right before it is about to burst when he is cumming in your mouth.
The hottest blowjobs I ever gave were to my old boyfriend, after he would come home from work and shower. He would sit in a recliner and I would service him, and he would be sitting there with his eyes closed while I did all of the work.
It feels way hotter when I am doing the movements instead of being 'facefucked' because knowing that the motion of my tongue and lips made him cum is what I think about when I masturbate later by myself.
It feels very satisfying, like a job well done, when your mouth is full of cum that you sucked out of a man.
I have sucked cock well over 100 times, maybe even close to 200 times, and I will never get tired of it.
