I orgasmed for the first time from penetration.

I was so confused when i felt myself getting close just from my boyfriend thrusting. And when I realized what was happening I was pretty much screaming and he looked so satisfied. I've never finished from us just having sex. Most of the time I feel like I have to focus when he's giving me oral or fingers to climax and it was starting to get to me. I just have to throw out there that that was the best sex I've ever had and even though I'm 18 I'm still learning things about my body I never knew. It was amazing you guys. 😩💕
