Masterbation

So I'm 15 and I'm ya know not allowed to have a vibrator yet but I really really want one my mom is very nosy too so it's difficult. So I have really bad breathing and I have to take a breathing treatment everyday and the machine that I have vibrates pretty intensly and I wanna try using the machine as a vibrator but like idk, cause I'm tired of using a tooth brush it takes forEVER but I'll feel ashamed if I use the breathing machine HMMM
