Queen Rena excels in nipple training, skillfully stimulating any nipple with her fingers to heighten the entire body's sensitivity. To intensify the sensation, she uses cold stainless steel medical instruments to tease the nipples, drawing out desperate reactions from her male slave. When electric currents are applied, the slave's penis becomes fully erect, prompting a satisfied smile from Queen Rena as she continues her relentless nipple torment. As a reward, she grants him her sacred pissing fluid, causing his cock to swell even further, driving his mind into a frenzy of explosive, hallucinatory ejaculation.
