First orgasm from penetration alone

I was fairly young but it was the day of my 15th. The day was amazing, a lot of my family and friends getting along and all of us just having a great time, vibing with the music and dancing etc. There is a moment where me and my bf were dancing and everyone were watching us. It was very romantic but I felt so much sexual tension. I was feeling it and I know he was too. After the party he begged his dad to let him use the car to take me home, they agreed as they trusted us. We get in the car, he parks somewhere more secluded and we just start making out, we both knew what we wanted to do. We already been having sex at this point but this day was just different, I felt so much love. I had taken my dress off at this point so as he takes my remaining clothes off, and he starts kissing all over my body and starts eating me out. It felt very pleasurable, as I start rubbing my clit, he grabs my feet placing his fingers between my toes and fingers me with his other hand and I let go, he tries to continue eating it but my vagina is very sensitive at this point lol. After i do my thing to him and after a while I sit on his dick. As I’m grinding on him I’m just hugging him up with my head on the side feeling very relaxed and in pure pleasure, as he starts kissing my neck he repositions himself and I arch my back a little bit and my god it starts to feel so much better, every time I grinded faster and faster I felt contact in my clit and felt an orgasmic feelinhg building up. I hear my bf moaning and I start to moan louder and louder too as I get closer to orgasm. He mumbles to me “i fucking love you” as I grinded faster moaning very very loudly at this point until I reached my climax. My legs start trembling , I start squealing and mumbling, I felt the rush from my feet all the way to my head, this is the strongest orgasm I’ve ever felt I almost felt like fainting, I feel my bfs dick pulsating. The first orgasm with penetration alone. It last over a minute and when it wore off we were just catching break, we start making out endlessly. Repeating I love you. He gets hard again, and I start grinding again, he starts humping from the bottom and I’m going crazy out of my mind at this point. I then start doing my part and starting humping him as fast as I could, feeling my ass clapping along him I felt like i was out of this planet, I forgot we were even there. He starts thrusting at the same time, I start to orgasm again. As I am I ride on him as fast as I could as he holds on to me as he’s finishing again. I start crying at this point , this is the best I’ve ever felt in my life , the best day of my life actually. Everything went perfect that day from the party to the sex. We stop as I hear our phones ringing, over an hour has passed we had to go our parents were worrying. We change up fast and he takes me home, I had a grin on my face for weeks straight lol, and from now on sex was my new heavy addiction.
