Oh gosh. I've done this but I forgot to say the word cock. Legit. I don't know what I was planning to say when I started speaking but I most certainly did not love him. It came out as an "ohhhh fuck I love......" and then there were no words to complete that sentence. Or there were too many words. I don't know. Luckily, he knew exactly where I was and didn't make a big deal about it at the time. He just slowed down and made me beg. He really enjoyed fucking with me when my senses were overloaded. We laughed about it later - he would randomly bring it up, saying, "So, I've been wondering what you love." Every time I would stutter trying to explain myself before realizing he was just fucking with me again.
I KNEW that this had to have happened to more people than me. It's just, like, when you get in that moment where you're likely to say you love someone's cock, you're likely to be in the heat of things, and there's thrusting, and sometimes thrusts cut off the end of your sentence for you.
