Hydro Or Water Pump

Hello guys since I’m still living at my parents I really don’t have much privacy and my parents always complained about how much time I spent in bathroom (doing PE) so my question is do you have any suggestions for a good hydro pump that can make me gain some girth ? There is such thing a hydro pump that doesn’t make lot of noise ? Can I use penomet or bathmate without water like in the bedroom? Any suggestions and tips will help.

Don’t buy that overpriced stuff that you can’t check the pressure

Get an air vacuum set some water lube (most easy to clean) and do it your bedroom

After clean it hide it in a shoe box until the next training
