"I might as well make my girlfriend dress up in an idol costume and do all sorts of naughty things..." I became a fan of a certain idol. My desire to have sex with her grew stronger day by day, and I came up with the idea of having her dress up as my girlfriend! I had her wear the clothes I prepared, and we changed into live clothes, and then I played around with her, came inside her, and took her out on a date and gave her a blowjob! She was also excited by the fact that I was different from usual, and asked me, "Does it feel good to have sex with me in a costume? Do you want to cum?" I think I'm going to get addicted to this!
