MISM-403 [Uncensored Leaked] Well-trained Supreme Nipples - Golden Spiral of Nipples - Yuri Adachi

Yuri Adachi is a masochistic woman with a remarkable sexual appetite. We discovered that roughly treating her nipples causes her pleasure index to rise abnormally, so we decided to train her by focusing on nipple torture. We tied a 1kg weight to her and swung it like a pendulum while we tortured her deep in the throat, causing her to convulse and her eyes to roll back. We continued to rotate her nipples with such force that it seemed like they were going to tear them off.
