Mistress Ava Black has a fun new toy, pyramid nipple clamps. Well fun for her but not so fun for the slave. “Arrgh” the slave screams as his nipples are elongated and stretched by the pyramid clamps. Mistress tortures the slave’s stretched nipples with her pin wheel. “Did you think the stretched nipples were torture enough slave? Well you were wrong”. Argh, argh, arrgh”. “Thank me for the pain”. The slave thanks her profusely. “Pain has a weird way of incentivising slaves” observes Mistress Ava.
