I masturbated with my roommate and she admitted something to me that turned me on like crazy

I shared a flat with a girl in my university, who was pretty chill and awesome overall. Definitely the quiet type but not like I'm super extroverted either so it works. Was pretty impossible to hide my sex habits from her and she's been surprisingly chill about it.

Few years ago, in one December we we chillin just us. Drinking wine while watching a movie. Don't remember how but we were talking about masturbating cause she's caught me before and I asked how she is so sneaky about it (ofc she started off all like "I don't masturbate" lol)

I'll skip the convo but we masturbated together. Like full on spread facing eachother and telling eachother about our turn ones. We got super into in so much that we touched our pussies together. Things got super sticky. She was telling me about something that turned her on that she didn't want to say cause she thought I'd get mad. I kept poking. She told me it made her wet how easily I've picked up girls in the past, and she was envious of them, when she heard sounds coming from my room about them begging, getting spanked etc.

We really went at it after that. I told her to be blunt, and even put her on my lap to get her first spanking. Asked her how she felt and she said that it turned her on that I was such a slut. That she didn't think she'd be such a whore.

I came so fucking hard I thought i was going to pass out from the exhaustion!
