Tenderization of the slave's ass

The horny suffering for its Master on its pleasure bench is always a highlight of cunt's week. It makes cunt horny to anticipate sitting with the fat plug up in its cunt and spikes painfully digging into the flesh of its bare ass.

After an exhausting 30-40 minutes of squatting and riding on the plug, Master ordered it down hard in one go, where cunt could "rest", in agony. After a few minutes of surrender to the pain, Master ordered cunt to attach its claw clamps, intense but very horny pain of the needles digging into its teats.

Legs very wide, extra exposed feeling, and the horny suffering began. A "warmup" phase followed by a plug riding break, and then the renewed intense pain, where cunt couldn't stay silent. Master closed its hood. Sitting and waiting in darkness like a torture object. Feeling the fat plug in its cunt. Thinking of the fatter plug that Master might make cunt wear to replace its current one increased the horniness in its cunt. Occasionally the horniness was rising a lot, the slave cock attempting to get hard in its cage and leaking. Feeling the clamps swing, move and torture its teats, horny pain...fantasies of horny men watching and taking pleasure in the slave's suffering. 

Afterwards cunt humbly thanked the plug with its mouth. Thanking the plug that brings cunt's cunt such pleasure, during and afterwards. And thankful for the torture and humiliations that Master makes it undergo.
