I've been enjoying more because of quarantine and now I have a lot of beer cans that I need to flatten to put in the recycling bin.  I know a fun way to crush them down. Use my ass!  I stand up and pull my panties down and get to work.  I grab a can and bend a bit forward to spread my ass cheeks to try and get the can as far in as I can.  Once I get it in I start to use my ass muscles to crush it down.  I squeeze as hard as I can and you can hear it crackling as it starts to crush down.  When satisfied with how flat that section of the can is I move it to the non crushed part to smash that down.  The first can doesn't come out to flat but I have plenty of others to try and crush flat.  So I grab another and try again.  Sometimes I'm squeezing so hard I grunt a bit and ball my fists.  I try to get them as flat as I can.  When done I show all of them and some have gotten really flat and others I did an ok job at but all good enough to get into the bin.
