A passionate sexual encounter with my youthful partner in our private residence

Recently, my girlfriend and I have been spending a lot of time in our private residence, exploring each other's bodies and indulging in our desires. One day, as we were getting intimate, she expressed her desire to be penetrated. I was more than willing to fulfill her wish and after some foreplay, I positioned her on top of me and began thrusting into her. Her tight, youthful body took me in with a smile of pleasure. I could feel her excitement as she rode me, her small breasts bouncing with each thrust. The sight of her youthful 18-year-old body on top of me was a sight to behold. After a few minutes of riding, she let me take control and I continued to pleasure her until I reached the climax, filling her with my essence. It was an intimate, passionate encounter that left us both satisfied and yearning for more.
