2.5 hours of suffering

Pleasure bench time. Master had cunt wear the spiked suction cups for teat torture. Maximum suction is achieved by starting out flat and then twisting them open. Only a bit is enough to already feel strong pain from the spikes digging in. Every minute or so cunt could twist them a little further, renewing the pain each time, until cunt had them fully screwed open.

The required sitting duration turned out to be about 1.5 hours; the last 45 minutes with closed hood waiting for Master's signal. Suffering in darkness, breathing more difficult, focusing on the burning in its ass and teats, the humiliating horniness from the fat plug up its cunt. Feeling its slave status and the humiliation in advance about asking for extra suffering time...and nervous because it knew there would not be a way back when it asked its Master to have cunt sit for another hour...

Of course the pain slowly increased further and further, real agony and submissive endurance well after its Master was already gone. Moaning/crying from its ass being on fire, throbbing. Thinking about how it asked for it...And when it finally got off its bench after 2.5 hours, walking and sitting was painful due to the burn...
