This is a very specific thought, but one I have had for the longest time as well! I finally asked and after 20 minutes of basically begging, she finally told me something. She said she thinks of a one night stand she had 20 years ago with some friend of hers that come to town to visit one day and they hung out all day and there was sexual tension all day and then they finally fucked and she said it was the hottest sex she ever had.
I was so dumbfounded to be hearing her say this, i layed in bed staring at the ceiling awake all night thinking about it. Who was this fucking guy? Is she friends with him still on facebook? Wtf did he do to her that was so hot? I admit I was jealous, but I asked for it so i definitely dealt with it quickly. I also was sure to not let her know i was jealous 'cause that would jeopardize any further chance of her telling me hot ...... like this. I kept a smile and was like "there we go! that's fucking hot as ......!" while simultaneously thinking "jfc this is a mindfuck"
