must be kinda hard with your little sister walking around the house all the time. If the dude was on 500mg of test and had to pin twice a week yes that would be fairly easy to hide, but I dont think thats the case 
Detailed answers here fellas on where to hide shit I need some ideas myself the under the bed/in a cabinet is too risky I need to get creative like Evan. 
i see your question, and i raise you this:
where does your mom keep her cum filled condoms from other guys fucking her ?
