How did you end up swallowing cum for the first time with a guy?

Fucklicking. I went from sucking her clit to get really worked up with his balls dragging across my face. Soon my tongue went from clit, to shaft, to eventually just engulfing him in my mouth when he slipped out her pussy. She joined me and we blew him until he gave us both a facial. I sucked what was left out of his dick. Loved the taste.
Omg, so fucking hot.
 
Probably not in the usual definition of this. I am only interested in doing this with my wife after she has been with Lovers. I think most definitions would siggest an interest in cum from any source, like my wife was when she was in her 3 year BBC exclusive period. By the time it ended, the only thing that mattered to her was that the guys were Black and she would have sex with them. That is my concept of a "cum dump".
But, I imagine in terms of AMOUNT of cum I have eaten over the years as a result of her affairs, I probably meet that definition. Her affair with her Boss/Lover lasted 11 years, and they were together 2-3 nights a week and many weekends also. And the traveled for business together during that time too. I cleaned her up every time she came home, wherther it was an evening in town with him, or after a week long business trip.
Never had any urge to ingest cum in any other manner tho. Just from my wifes cunt. CW
I haven't eaten a lot of cum so far but I love being humiliated and called demeaning names.
 
I explained all my fantasies to my new wife before we got married. Last weekend when I got home I was made to undress and be on all fours. My wife made me suck a male friend of hers while another used a Dildo on my back door. She kept telling me how worthless I was and these were real men. She laughed and held my throat while I sucked his head. I was never so excited. Being my first time by back door hurt, but, the more it hurt, the harder I sucked. I swallowed and while the taste was not so good I loved it. I thanked my wife for a wonderful gift.
 
I was so turned on by being forced to take it.
If you can channel your inner submissive tendencies towards pleasure while being dominated by a hung aggressive alpha male, the results can be astonishing. You might be surprised by just what you will do for a guy once the action starts. You certainly wouldn’t be the first formerly straight guy biting a pillow with a big cock up all the way up your ass, grunting through an intense sphincter stretching, and wondering how you winded up being an alpha male’s Fleshlight. Your wits generally return once the sperm hits your colon and you do the walk of shame to the washroom to clean up. That’s also when your realize your burning ass is dripping cum … and you vow to never do that again. But you do anyway.

Yup, it seems most guys get hooked after their 1st cock. I sure did.
 
Since my teen age times i used to jerk off and cum to my mouth and swallow. After i got married to my wife i started having this fantasy about sharing her with another man, when it finally happened i couldn´t help but feel like i wanted to suck his cock. the third time i shared my wife with another man, some how i felt that he would let me, so, in the middle of the action i just grabed his cock and gave him a blow job, he told me when he was about to cum but i didn´t care and toke the molk in my mouth and swallowed it all, it was amazing
 
My friend and I were masturbating together to some porn, and one thing led to another...before I knew it I was sucking his cock. He was smaller than me and circumcised. The first few times, I just jerked him off until he came, but eventually we began experimenting with oral sex. I let him finish in my mouth a few times before we went our separate ways...
