She had long been asked by her boyfriend to wear a bunny girl costume, but she had no interest and kept refusing. Again that day, while on a date in Shinjuku, he seriously asked her to wear one. With no choice, they changed their plans and headed to Donki. There, they checked out the cosplay section to buy a bunny girl outfit. The designs were cute and varied. As she looked through them, her dislike toward cosplay gradually faded. She even started feeling like trying it on herself, but ultimately decided to fulfill his wish and bought the bunny girl costume. The next Sunday, he came over to her place, and after spending some time together, they immediately tried out the bunny girl costume. As expected, it was high-cut and made of thin fabric. Seeing her in it, his expression changed noticeably. When he touched her nipples through the outfit, she couldn't help but moan. The mood grew increasingly erotic, and before she knew it, her groin was wet. The dark color might have hidden the stain, but with any other color, it would've been clearly visible. He said, "You've got a naughty wet spot down there," and "You're soaked even through the fabric—Yui is really such a slut," as he continued teasing her. Her desire kept rising, and wanting his cock, she pulled down his pants and underwear to give him a blowjob—only to find it surprisingly hard. Normally it wasn't like this, but today was different. When she asked, "You're turned on by my bunny girl look, aren't you?" he got even more excited. He pulled aside the crotch of the costume and started thrusting into her from behind, hard and fast. His cock was rock hard, and she was wetter than ever before. She never imagined she'd feel so aroused wearing a bunny girl costume. In the end, he came heavily on her outfit, looking deeply satisfied. Watching him, she felt a new desire to try more cosplay. In this shoot, we'll have her experience sexy cosplay as a bunny girl once again, based on her real story.
