Oral Embarrassment

So me and my fwb just had sex but during everything was going great as normal we were making out foreplay was amazing until it was my turn to give him some pleasure. Now I am proud of my skills I know I can get the job done and then some but tonight idk but I had him in my mouth and I usually spit the first time was great and then I kept going deeper and deeper and then I felt myself gag so I came up and wanted to spit but.....I threw up 😣😣😣😖😖😖😖😖😫😫😩😩. I have never been more embarrassed in my life but thankfully either he didn't notice or knew I was already killing myself inside he just grab a towel cleaned off and I cleaned as well and yea continued on. I know it sounds gross and I most likely will disappear from him for awhile but he was a complete gentleman and even kissed me goodbye when I left. (After I rinsed out my mouth of course. He didn't know I did but I had too) please tell me this has happened to someone else 😖
