COM-223 "I want to experience the warmth of a woman just once..." A middle-aged virgin (currently on leave) tries having sex for the first time with a beautiful girl!

I had no intention of keeping it safe, but I hadn't had sex until this age (51 years old). But finally, I've gathered up the courage to graduate from being a virgin! When I welcomed a girl into my apartment, the gray space instantly transformed into full color. We took a shower together, got into the same futon, and warmed each other's bodies, and my heart was pounding. I sucked her soft breasts and did the cunnilingus I'd always dreamed of. I don't know how to do it, but she seemed to feel it when I licked her as hard as I could, and I was happy. Then she licked my penis, and when it was erect, she put on a condom and we did it in a cowgirl position... When I tried to insert it, it was probably because I was nervous, but it was flaccid and wouldn't go into the woman herself. I never thought that my penis would be a hindrance at a time like this... Will my first experience go well?
