Time for some extreme depth training up my ass as well!  Obviously I love taking my longest dildo at about 17" insertable down my throat, but it's time to feel all that length and those wonderful suction cups going up my ass as well!  Can I fit the whole thing up my ass like I can down my throat??  I can!! Although with all the lube it's slippery and tricky getting it up my ass by myself.  Pulling it out feels so good though, and being able to taste myself as I put it back in my mouth and throat from my ass is HEAVENLY!
