Okay so I know how hard it is to turn yourself on, especially without help or any kind of toys. Most people on the internet suggest anonymous sources from where you can order this sketchy stuff but WHAT IF YOU ARE A BLOODY TEEN WHO LIVES WITH FAMILY?
Vibrators are super expensive and I'm pretty sure it'll be hard to explain to your mom why her teenage daughter is ordering a penis shaped vibrating object.
I looked and looked and VIOLA! I found us the perfect substitute!
There is an app called "Vibration and relaxing sounds"
You can download it from the app store and then open it. It'll lead you to the main page and set the intensity to hundered. Shift to regular mode, so that there is no long breaks in the middle.
Now place the sound outlet of your device over your clit, over the underwear preferably, but if you want direct contact, clean the device throughly and touch it gently to your clit.
For added lustful effect, switch on the rain sound effects and enjoy!
