If I'll store it in the fridge (not freezer), for 1-2 days, how's that? It will be okay?

Well ... I know it's best to freeze it (I just wanna do some webteases from here). But ... problem is, my parents are home very often and I don't know where to store it so they won't find it. You think if I'll put the cum in that ice cubes thing, and in water in other holes, it will look different ...
