I haven't gotten my ass fucked by a cock yet. I sometimes use a 8" dildo, but no real dick there yet.

But I remember having an amazing time with a real hot & buff daddy in a adult arcade. After he sucked me really good, he whipped out his cock to get sucked. Wow! I didn't know what to feel! I got super nervous but incredibly aroused. It was 8 or 9", and I could hardly get my mouth around it because it was so damn thick! I dropped to my knees, sucked him, and starting stroking my cock. After a while, I swore his dick got even bigger, harder, and thicker as I was choking and gagging on it. It felt amazing! My mind was going blank right before he came in my mouth. Happily swallowed that load.

Kind of wish he would've been able to fuck me right after that, but I think he had to leave right after that. Still, what a fun time that was.

You are one lucky guy. I am still patiently waiting to suck a BBC, I would be in heaven, especially a uncut one, I have never had either a uncut or black dick.

but i still want to find that proverbial "hung like a horse" one! ;)

For me it was BBC in an Adult Video theater
 

There is a "club" in a central Florida city (for privacy I am not going into details) that resembles more an Adult Video Arcade than a sex club. I went there once before, and it was pretty tame. Just two or three other guys, and just nothing really going on in the booths or two theaters. Anyway, I was in town for something else, and had time to spare, so I thought let's try again...
So I arrive late afternoon to learn the place is closing down in a few minutes, and the lone attendant was cleaning up... So I was going like 'ah man, that sucks..." but after a few awkward moments the attendant let me in anyway. Indeed, no one there, the long row of booths empty... so I went to the one theater where he was finishing up cleaning, there was brief talk along the lines when the best time would be to come... The attendant said I could sit down on the leather sofa and watch porn... I was so horned up all day, I did sit down... Straight porn, a bitch was getting it rough and hard on the beach, just how I like it. I did jut get hypnotized watching it, rubbed my crotch, at was hard. On top, I like to come in running pants, long soccer socks, sneakers and sweatshirt to places like this... I really had no agenda or plan, I thought the place is about to close, but things happened almost like in a hot porn from here on... While cleaning the other sofa, the attendant told me, I guess liking to watch me all horned up, this is a place where you can be naked... I slid slowly out of my running pants and sneakers, my bulge very visible through my white sport trunk briefs... It did not take for him to just slide his pants off, and while he was a nice, average guy, I just did not expect this XXXXL aubergine cock suddenly to dangle in front of me... I did not even blow him hard, just used some spit and my hands to massage that thing... It was clear, though, he wanted to fuck, and I told him I have condoms. I got up, slid out of my underwear and got a condom out of me running pants on the floor... As hard as I tried, I could not get it on him. I did not even manage to get it on the tip of his cock, let alone the shaft. Well, he managed and rolled me on my back, one leg in hot soccer socks over his shoulder. He slowly entered, but it was not a gentle entering, it was a slow moving freight train with so much momentum impossible to stop. So there I was on that couch, he fucked me hard as I stole a glimpse of the porn where that bitch got fucked just as hard as me... After some time I took off my sweatshirt and turned on my back, where he continued the rampage. I felt such a whore, I wanted to be naked for him to use me. Well, after some if this insane fucking, he rolled me on my and towered over me, telling me to cum. I thought I blew a load only to be soaked in squirts of his cum... It must have taken half a roll of paper towels to clean me up... I dressed, left, and he closed up. Crazy, I thought, one just never knows! By the way, if you live in central FLA oder south FLA and need a married guy to use and abuse, give me a shout.

Living in central Florida myself, I'd sure like to know the name of this place. Care to share?
