Blowjob gone wrong

Last night I was giving my boyfriend a blowjob and he was pushing my head down on his dick and that triggered my gag reflexes and I was like "okay be careful" and it happened a couple different time. (He had a shitty day so I wanted to do something for him). He was about to cum but I stopped and he pushed my head back down and then he came and he pushed my head down so far and hard I threw up. Thankfully it wasn't all over him or his dick. Just on the floor of the car and outside 😂 most embarrassing moment ever. He didn't care he thought it was funny
