Anal punishment on the F-machine

Description: There is a fundamental rule in my world and that is that the punishment should fit the 'crime' where possible, and today is just that day.  i have behaved like an ass, so it is my ass that will be punished in a punishment called '2-way stretch'.  i am to take the small dildo in my ass, the fucking machine pounding away faster and faster stretching my very tight ass hole, while i take the bbc dildo in my mouth, my lips stretched round it sucking away on as deep as i can go.  here is the jeopardy for me.  if i manage to keep sucking on the bbc dildo without gagging and releasing my mouth from it, i keep the small cock pounding away at my ass hole.  if i fail to suck on the bbc cock, this is then swapped onto my fucking machine and the bbc cock stretches my ass hole really wide.  unfortunately for me i do not manage to suck on the bbc cock properly, so my ass is treated to this cock, which i really struggle to take at first!  the bbc cock is then left to pound away at my ass hole faster and faster until i have learned my lesson.   watch me struggle to suck on the big cock while my ass is fucked relentlessly by my machine, watch me struggle to take the big cock in my ass as it stretches me further than i have ever been before in my anal training.  watch me beg and plead to be released as the big cock stretches my ass nice and wide.  finally, watch my pussy become really what as i clearly get a kick out of my anal training!
