i gave my colleague a blowjob in work

so i (23f) gave my colleague (39m) head in work today and i just neeeeeed to get it off my chest. we’ve always had a sort of cheeky/flirty relationship and ive been into him since i started last year, but i assumed he wasn’t into me because ive heard him say the youngest he would ever date is 25/26 because he has a 23 year old niece. i thought he sort of viewed me as a kid. last week, i asked him to do something for me and he gave me a cheeky smirk and said ”what’s in it for me?”. i said “whatever you want.” and he said a blowjob. i laughed and said okay. i thought it was a joke because we would sometimes get on like that. this guy hasn’t had a girlfriend since he was around 18/early 20s btw. my colleagues say he’s totally shy and can’t talk to girls, and he’s told me before that he “doesn’t do one night stands,” so i never thought this would ever happen. anyway, he did the favour for me. throughout the week, he made comments and jokes about it. today, he said he was going down to an empty room to put something away and he was going to wait a few minutes extra in case i wanted to come down and ‘do what i owe’. we work in a doctors surgery. so i went down to the empty room - i thought he was messing with me, but at the same time i wanted to do it. i went in, he asked if i was going to do it, i talked about ‘what if we get caught’ etc and he said no one ever comes down here. i said “i can’t tell if you’re joking with me”. he said “do you need me to get my cock out to show you i’m serious?” and then he did, and he put it in my hand. i was so stunned, i was blushing. he asked me to get down on my knees, so i did. i gave him head for about 5-10 minutes and then he came in my mouth. after that, we left separately and we didn’t see or speak to each other for the rest of the day.. not necessarily intentionally, just that he was upstairs doing work and i was downstairs. im at that point where i’m like.. did that even happen? even during it i felt like that😆
