Exclusive: Don't you have sex after everyone's asleep? Yui 300MIUM-1300

Today is my part-time colleague's birthday party. I just randomly bought a vibrator as a gift, and Yui immediately tried it out, haha. These people are so funny! Our idol shouldn't go too far. This kind of youthful atmosphere is only available now... I still need to find a job... While thinking this, I took a leak, and Yui suddenly came in and asked, "Hey, will you be angry if I take my clothes off? ///" What are you talking about? After going completely naked, Yui also started taking off her clothes. How will this develop?
