Rape Kink Origin: Losing my virginity at 18, to my supervisor [m27]

I was ecstatic to get my first part-time job at 18, even though it was at a slimy fast food restaurant. The thought of finally being able to afford my own phone, makeup, clothes, etc. motivated me to work as much as my tight school schedule allowed me to.
My manager positioned me to be the cashier, so the front face of the restaurant was a cute, young, preppy, teenaged girl who was always excited to serve hungry customers & potentially get a tip.

He [M27] was my supervisor, who trained me from the first day. He showed me around the restaurant, taught me how to punch in orders, and on slow days he would show me around the kitchen too.
It started with him offering to drive me home after work, and I’d let him. Sometimes we would just sit & talk in the parking lot. Over time he began to take me home the long route, and sometimes rested his hand on my thigh. During our shifts together, he’d text me about how good my ass looked in the uniform. One day, we were getting issued a new & improved design of our uniform, and he gave me a new set that was a size too small. It was gave me an obvious camel toe, wedgie, and the buttons on my top showed chest a bit. It was embarrassing, but this encouraged him to start groping me at work. He’d walk up behind me to help me at the cash, while grabbing my ass & rubbing my pussy between my thighs. I was too shy to say anything, so I let it happen. The sexting and groping at work became a regular occurrence, but I thought that the attention was nice so I never stopped it.
