Hey guys, I'm on vacation, and I want to masturbate so bad. Unfortunately for me, my sister and I share the same room. And, I can't do it outside because people come and go to the neighborhood. The bathroom is the trickiest part, it has a lock but it doesn't work. Sometimes, it's hard to have self-control but at the same time you're horny as fuck so what can you do. If you guys know what to do, please let me know????
