Great body, great cock, great story. I've jacked off in public, naked, a lot, even in populated areas, love the thrill. Try going out in the hall with nothing on, not far, but just a few steps outside your door and/or go out with something up your ass already. If your building has an elevator and it's the main thing used, try stripping in the stair well. If you have a balcony, try some stripping/playing out there as well.
I also would love it if you took vids/pics of you doing that but get it if you can't. Thanks for sharing, hope to see/hear more.
