Learned from Mom
Growing up my mom found out that I had my first girlfriend and kept ribbing me about it. It was embarrassing. She asked me if I had kissed her yet, and I said yes, but I wasn't sure if I was doing it right. I asked mom if I could practice on her and she could give me feedback on my technique.
We were home alone and she said "sure" and we locked lips, then probed tongues. We were making out hot and heavy and she showed no signs of wanting to stop, and I sure as hell didn't either. It was summer and she was wearing cotton running shorts. I got a little bold and reached down and rubbed her pussy through her shorts. She discretely moved my hand up to her clit as I kept rubbing through the fabric.
After a couple of minutes she exhaled a moan while we were kissing and said "You do that well." I said, "Kissing?" She said "No. That other thing you were doing." We never had another make-out session.
