I’m 19 and I fucked my driving instructor while my mom was waiting in the car outside

I’ve been taking driving lessons for the past month. My instructor is 38, married, and honestly pretty hot in that older guy way. He’s always been professional but I noticed him looking at my legs when I wear skirts. Yesterday my mom came with me because she needed to go somewhere after the lesson. We were practicing in a quiet residential area. At one point he told me to pull over because I made a mistake. My mom was sitting in the back seat on her phone. He told her he’ll show me something on the hood of the car real quick. We got out, he opened the hood… and two seconds later he had me pressed against the side of the car, out of my mom’s direct view. He pulled my skirt up, moved my panties to the side and fucked me right there. It was super fast and risky. I could hear my mom moving in the back seat. He came inside me in less than two minutes. I got back in the car with his cum dripping down my leg and continued the lesson like nothing happened. My mom had no idea. I even drove the rest of the lesson while feeling him leak out of me. When we got home I went straight to the bathroom and cleaned up. I feel like such a whore for doing that with my mom literally 2 meters away. But the risk was insane and it turned me on more than anything.

He already texted me for the next “lesson” tomorrow. I know I shouldn’t go… but I probably will.
