I (26M) still think about that wild night with my 19yo college intern last summer

Throwaway for obvious reasons. I'm 26, from Ahmedabad, work in a small IT startup that has some interns from nearby colleges. Last summer, we had this 19-year-old girl (let's call her R) doing her internship. She was the typical "good desi girl" on the outside soft spoken, always blushing when I spoke to her. But I noticed how she started staying late, finding excuses to come for walk on lunch & tea breaks, and the way her eyes would drop whenever I gave her direct instructions.

One Friday evening, everyone else had left. She was still there "finishing a report." I told her straight up, "R, it's late. Lock the door if you're staying." She did it without a word, then stood there fidgeting.

I sat back and said, "You've been acting different around me. Tell me what you actually want." After some hesitation, this innocent-looking girl whispered that she gets wet whenever I get strict with her. That she touches herself thinking about me treating her like a slut in private. Fuck, that flipped a switch.

I made her prove it. Had her lift her shirt, pull her skirt down, and show me how soaked her panties were. She was trembling but dripping. I didn't even touch her at first just made her stand there, describe out loud what a horny little submissive she was for her senior . Then I bent her over my desk, used her belt to tie her hands lightly behind her back, and fucked her slow and deep while telling her exactly how I'd use her whenever I wanted.

She came so hard she was biting her own arm to stay quiet. Called me "daddy" the whole time, which honestly did something to me. After that night we had a few more secret sessions before her internship ended car rides where she'd suck me off in the parking lot, quickies in the office store room, even once at my place when my family was out. She loved being told what to do, being used, being praised for taking it like a good girl.
