Pleasure bench and cock sucking training

1 hour and 45 minutes on the pleasure bench gave cunt a throbbing burning red ass again. 

Impaled on the fat plug, feeling the spikes dig in, cunt was given the task of practicing its cock sucking skills. The humiliating combination made cunt feel what it is good for. It was thinking of the horny men that would expect to be able to shove their cock deep in cunt's throat, as it practiced on its gag reflex and on dilating its slave throat enough to take the dildo balls deep. Each time it had to gag, its ass contracted painfully on the spikes.

Half an hour of enclosed darkness after Master told cunt to zip up its hood and wait. When Master's signal came, the torture was not yet over and Master put it back to work on practicing with its dildo...until He finally decided that cunt had had enough and was allowed off its bench.
