I met Mizuki through the internet and arranged to meet up, though my real intention was clearly to have sex with a current college girl. When she arrived and saw me filming, she asked why I was recording, and I casually revealed my fetish, saying, "It's a hobby—I'm into gonzo sex videos." Despite her nipples clearly visible through her clothes, she remained completely confident even with many people passing by. We chatted and decided to grab a meal at a nearby restaurant. On the way, I asked if she wanted to stop by an adult shop, and her eyes lit up as she eagerly replied, "I want to!" Inside, she picked out nipple-focused sex toys, explaining that her nipples are a major erogenous zone, and even tried some out right there in the store. Her body twitched and jerked with each stimulation, and she clearly enjoyed the attention from people around us. After buying several items, I asked her to wear a remote-controlled vibrator before heading to the hotel, and she immediately agreed. Once I turned it on, I could see her clit being stimulated, making her squirm with arousal. Despite strange looks from passersby, we made it to the hotel. I confirmed her nipples were fully erect and began intensely teasing them. She was so sensitive that she nearly climaxed just from nipple play, so I used the toys to push her over the edge repeatedly, making her squirt multiple times. I also learned she's regularly trained by her master, so I took full advantage. Riding me in the cowgirl position, she performed deep throat, sobbing as she took my cock deep into her throat. With her mouth dripping saliva, I switched to missionary and began bareback sex. She climaxed over and over while gushing fluid, driving me wild with no chance to stop. I finished with a creampie. But such a rare gem was too good to let go after just one round. After making her clean me with a cowgirl-style deep throat, I confirmed my erection was back and thrust inside again. As she twisted her own nipples and orgasmed repeatedly, I emptied the rest of my cum all over her face. At one point, she apologized to her master, which only intensified the feeling of her complete submission and turned me on even more.
