My Building Staircase Is A Sex Toy

Late nights, I smoke weed in my staircase and im a freak to be getting fully naked stroking my cock knowing no one would be walking in at 3 AM with no security in the building. The railings of the stairs is a solid frame that goes up but has a bar handle that goes on top leaving a good two finger gap in between the frame and the bar handle that is stacked on top. I put my cock in between and started to thrust and it was something where i was stroking hands free while smoking. I was only able to cum when i had my fingers under my frenum to rub my cock as i was thrusting but then i came across my vaseline jar and a zip loc bag. I rip the bottom part of the zip loc bag so its open and put vaseline in and put it in crack between the frame and handle and it felt like wet pussy. Im addicted to it, I get fully naked and fuck that staircase till I have a mind blowing orgasm. Fuck spending money on a sex toy when I have that hole and some vaseline with a zip loc to viciously fuck.
