I love sucking, even if there is no cum to swallow

Walked into Uptown ABS and saw a lot of closed doors to viewing booths. First door I tried, locked. Second door, occupied by one sucker and one suckee. Third door, unlocked with a Black guy watching porn. I closed the door behind me and knelt down as he sat in the chair. My eyes had not adjusted yet to the darkness as I fumbled to find his buckle and drop his pants. He knew what I wanted and undid himself to reveal his luscious cock to my starving mouth. Still, my eyes had not adjusted so I could not locate his cock using only my mouth (You'd think I'd be able to find ANY cock by using my mouth, by now!). So I had to resort to finding what I sought by using my hand. Just as I was lifting his cock to my mouth my eyes could now see a gorgeous cut cock that was semi-hard and aiming directly toward my mouth. ANY cock feels great when it is in my mouth, this one was particularly magnificent if only because I felt so starved for delicious meat. He was about the perfect size as I was immediately able to bury my nose in his pubes with very little gag-reflex being an issue. My mouth had found nirvana and began to pump my lips on his cock while he sat and enjoyed my attention to his needs and wants. After a few minutes he stood so he could really thrust his hips and drive his cock into my mouth. GOD, I love being used as a fuck-face! He was fucking my mouth so aggressively he often popped out and I frantically seeked out his cock to resume its proper place, my mouth. After about five minutes of vigorous suckage he said he needed a break. I looked up at him and said something like, "Yeah, I can see you're sweating". But I could not leave his cock alone so I returned to what I wanted most, to just suck and suck and suck. Soon he was again actively fucking my mouth. After another fives minutes of utter bliss (for me) he pushed me away and said he must stop. I never like letting a cock out of my mouth but he was definitely suffering from overheating (not over-sucking). As I sucked him I so wanted him to cum and feel him thrust uncontrollably as he filled me with his warm cum. Even though he tried more than once to masturbate into my mouth he was never able to ejaculate and thus bring sheer pleasure to both of us. So I left the booth telling him, "The pleasure was all mine", and sought out my next cock to suck. I found another big Black, cut cock and knelt before him. He immediately proceeded to grab my head with his hands and fuck my mouth. I had trouble being able to get him into my throat without gagging. He told me he's a throater and started to put himself away. I was depressed I could not deep-throat him but for whatever reason I just couldn't. He was unwilling to help me get past gagging, so we parted. My next customer was an elder (or maybe my age?) White gentleman jerking off his cock while watching porn. I began to go directly to his lovely cut cock but he said, "No blowjob, just take out your cock and masturbate with me." I so wanted to suck his handsome cock but told him as much as I would have loved to join him my little dick doesn't get hard anymore (sad, but, true!). I took a look for any other "customers" in other booths but Uptown was surprisingly sparse on opportunity for a cocksucker like me at the time. I sensed I was running out of time to hang around and so I left. I really wanted a load of warm cum hitting the back of my tongue, but I so enjoyed the time I had with the first cock it didn't really matter that I didn't get to swallow. But MAN! did I ever love the privilege of sucking, sucking, sucking.
