Extensive cock sucking training on the practice dildo

Yesterday extensive training with THE IMPALER, opening up the cunt again for the rapes that it is for. This evening Master had cunt practice cock sucking on its practice dildo, giving it the opportunity to prepare for the loanout to SIR next week, and of course to improve its capabilities as a cock sucker whore in general.

During its training this evening, Master required the cunt to be plugged with the larger GK 85 plug. Deep throat training on its dildo with a well filled cunt. 

Cunt trained on its gag reflex by swallowing the dildo at different speeds, but always balls deep inside. It also tried keeping the dildo balls deep for as long as possible while breathing around it. 

Sitting there naked with cunt filled, concentrating on the dildo to prevent gagging made cunt think of moments when SIR would lock its head between his thighs while having his cock deep inside. A humiliating feeling: locked in place, the slave mouth open and filled deeply, just a stupid whore whose throat is used for horny pleasure.

Cunt was focused on improving its ability to do its job properly, for SIR and for other horny men to be able to use the slave mouth for their pleasure without hindrance. Extensive training this evening, and it was motivating to notice progression throughout the training. 

The throat is sensitive now, and cunt imagine it will be feeling it tomorrow. Perhaps a good reminder what the purpose of a slave mouth and throat is, and whose pleasure it is that counts.
