How do I masturbate with no privacy?

I just started college, moved away from home and currently am living with two roommates. There isn't any privacy for me to get some alone time like how I am used to back home. I couldn't even bring my massager with me because it's very obvious when I'm using it and it's also fairly loud.

I feel incredibly pent up these days and have no idea how to get off. I've been reading a lot of smut lately as is my right and GOD it's making everything so much harder!

My entire panties were soaked through this afternoon and I even had to change my pants (I didn't even touch myself I just read on my phone). I haven't gone this long without masturbating in around 2-3 years now.

I'm not used to having to hide my expressions or suppress my voice, especially at night. Additionally, I am very accustomed to my massager and fingers barely do it for me, so I have no idea if trying will even work.

Desperate for advice.
