I was 22, and was on a date with this guy I'd met on the Internet. After a not so eventful date, I brought him home to meet my parents, which I now regret doing. After talking for over two hours, he had to go home. I had been getting vibes from him all night that he wanted some non-sexual physical contact, whether it be a kiss, or a held hand. So, I walked him out.
We'd made it maybe three feet before he stopped dead in his tracks. I began babbling some incoherent thing, because I knew this might be the moment. He smiled, leant in, and kissed me. All brain activity stopped, but I was unaware of what was happening. My eyes were open, and my mind wasn't recepting. I didn't even pucker. Nine seconds later, I began babbling again. He lightly laughed, and leaned in again. This time, I was ready. I let go of all thoughts, closed my eyes, and opened myself up. These two(yes, two) were better than the first, because I was open to the experience. Or it might be because on the final kiss, his upper and lower lips sucked at my upper lip. It was truly erotic, thinking back on it.
A truly memorable experience, despite the little moment of awkwardness.
