Completely motionless, the slave lies wrapped in foil on the BDSM bed. The head is in a heavy leather mask. The mistress, dressed in red lace underwear, now begins to expose the only relevant part of the body. With scissors she cuts the foil around the cock. But no pleasure follows, instead she takes a steel ring, which is covered with many sharp spikes on the inside. She attaches the ring directly to the shaft and closes it with a lock. So the slave is now in a predicament. The more aroused and therefore harder he is, the more the pointy spikes bore into his cock. The mistress now starts to make the slave as horny as possible. For this she licks him gently on the cock with her tongue and sits on his face to get fun herself. The slave protests loudly. But she does not let herself be distracted and simply continues. The impact of the spikes is so great that the slave does not manage to have an orgasm.
