I've had this fantasy for a while.
And it all started when I was groped for the first time. It was in a mini market, this old man leaned forward and grabbed my pussy, obviously, me being a 10 year old, walked away. But I remember going home and thinking about it, hoping I wouldn't have walked away.
Then when my family and I moved into our new apartment, my father had asked me to go downstairs and guide the guy to out floor. I put on some clothes and went down.
He walked in the elevator with me, and as soon as the doors closed he walked backwards with his hand on my pussy. Obviously, I pushed him away and wanted nothing to do with it. He had trapped me between the walls and his back, pushing his hand further and further.
When we had reached our floor, he pressed for the ground floor again and continued to touch me. At this point my hands were on his back pushing him away. I went home touching myself wishing he had gone further and slipping his hand. He took two trips from the ground floor to the seventh floor and note that the elevator was slow.
Now, I rethink of that man. Continuing the fantasy of me turning him around and feeling his crotch. Letting him have his way with me.
Beside that, I also think of him threatening me to come an hour later on the building stair case last floor. Eventually leading to a daily thing where he uses me and I pretend to hate him but deep down enjoy it.
I fantasize about random men using me wherever they please.
There's something about me being useful to others that gets me, partially why I often go online.
