Anal toy ideas from household stuff, and what can I use for lube

Hey I'm 14 in January 15 straight but pretty open for everything (pun not intended). I have been enjoying putting things inside my ass lately. So far I can put a bouncy ball about the width of my penis inside my ass (don't worry there is a string at the end i can pull it out). Now I wanted to ask should I go any further with the width if yes what do I use for household stuff because we don't have any dildos here and I don't want to ask my parents. Oh and what can I use for lube because I don't think spit is going to work for ever.
