Pleasure bench pain

It was no surprise for cunt that it would be made to enjoy its pleasure bench this evening. It had eagerly fetched the bench beforehand. But when Master told it to put the black clamps on its teats and squat over the plug, cunt was trembling from horniness and submissiveness... 

Bulbs went inside and cunt was soon riding on those bulbs. Massaging its cunt and tiring its legs before being made to sit down hard...

Cunt was reminded of how the spikes hurt. Master told it to sit with its legs nicely spread wide. Time to suffer in this humiliating position with the fat plug hornily penetrating its cunt and pressing against its prostate.

Two times during the session, Master made it get up, ride, and sit back down. A break for its cunt but extra pain refreshment for its ass. During the second time, cunt could feel its ass throb and literally twitch from being hurt. With intense burning and loud moans it was then back to sitting for the remaining duration.

Cunt enjoyed 1 hour and 45 minutes of suffering and riding on its bench, and two hours with the black clamps on its now sore teats. Knowing it has one or two more of such sessions to look forward to this week...
