Tervicz tries to struggle as good as he can. But he's no  match for the dragon's ringmuscles. As he gets pushed deeper into the musky his struggles are dingling. Fatigue as well as an oxygen shortage within the arse tire him. His paws still twitch, but their movements become evermore scarcely. Eventually his struggles stop as the tight ringmuscle completely cuts off his air. No telling whether what lays ahead will contain enough air for him to recover.
