Mistress Reina trains the slave to be sensitive to any nipple. She thoroughly plays with the nipples with her fingers, further teaching pleasure to the slave's body, which has become sensitive not only to the nipples but to the whole body. She places a stainless steel medical tool on the nipple. The cold temperature makes the nipple feel hard, and it cries out for stimulation. When electricity is applied, the penis becomes erect, and Mistress Reina smiles with delight, continuing to tease the nipple relentlessly. The holy water as a reward makes the penis swell even more, and the slave's fantasies are instantly brought to an internal ejaculation. [※There may be some disturbances in the image and sound]
