Slave for Five Days and Nights in Amsterdam Part 4

The slave kneels on the bed. He is wearing the tight mask that gave him such good feelings in the morning. Now everything is different. Goddess Kamikatze attaches 2 spiked rings to his cock and has prepared a variety of nipple clamps.
These are sorted by strength and she starts with the weakest pair of clamps. Excited by the situation, the slave becomes hard, which is immediately avenged. The spikes drill painfully into his cock.
Then it goes on and on and on. Change nipple clamps, stimulate the cock, next pair of clamps. Soon the slave no longer knows what is happening to him. His nipples are in severe pain and he has to concentrate hard to stay still.
To make matters worse, the mistress lays her hand on the mask, but then quickly devotes herself to more nipple clamps. The last ones are the worst. They don't have a flat contact surface, but are a spike that drills deep into the skin.
The slave sweats with pain and exertion as the clamps are applied. Goddess Kamikatze visibly enjoys his agony and feasts on it. Completely exhausted, the slave kneels when she finally frees him.
