What does it feel like? For me, it feels great. It is my reward for worshipping the guy's cock. I love kissing, licking, sucking a large cock and balls. I alternate between deep throating him (I have met only one guy that I could not fit all the way down my throat) and other actions. His cock is usually wet after deep throat, so I fondle his cock using my throat juices as lube, all the while licking and kissing his cocks and balls. If he raises his hips, I will lick his ass and stick my tongue in it. I like caressing his chest, arms, legs, and ass as I suck hands-free. Eventually, I get into a rhythm in which I stroke him and move my mouth on and off his cock at the same time, his cock penetrating my lips and mouth to the rhythm of my hand stroking him. If I want to prolong things, I only do this for a short while since he will definitely unload very soon. Most guys don't want me to stop once I start that action and they end up shooting on my lips, chin, and into my mouth. Whatever cum is on my face, I try to push into my mouth by rubbing his wet dick over my face. I always continue worshipping his cock after he unloads, although some guys are too sensitive to let me do that.
Some guys like to hold my head and push their cocks in and out of my mouth, maybe even twist it around inside my mouth. They are more forceful and are fucking my mouth as they would a woman, and I do enjoy these more forceful guys a lot. These guys usually unload completely in my mouth. I like when they grip my head more forcefully as they are close to unloading. I love the feel of the first squirts touching my tongue and inner cheeks. Then my mouth fills up as the guy keeps pumping inside my mouth. When they finish, I savor the load before swallowing it. Other guys pull out and jerk themselves to finish, and I quickly put my lips around the head of their cocks to receive their loads.
I love giving oral. As I said, my reward is a mouthful of spunk. I guess that I am a born cocksucker. I also love giving oral to women, feeling them buck against my mouth and face.
