It was a bad threesome dating

I have once tinder threesome dating which is terrible. My neighbor was a couple who are nice and good-looking. I was single at that time, so they always invited me to have a dinner or hangout. One day, they brought to the idea of threesome hookup. With some drink, I said yes. Honestly to say, at the first, it was amazing. The husband kissed his wife, and the wife touched me gentle and take off my close. But gradually, they concentrated on each other, I was left out.
