SSIS-909 Aika Yumeno, a perverted office lady who was forced to act as a swimsuit model...couldn't forget her excitement and got addicted to group sex.

I joined the company because I wanted to be a swimsuit designer, but due to the economic downturn, I ended up helping out in the sales department instead of in the design department... Due to a schedule management mistake by a senior who couldn't work, a model came to fit a new swimsuit with a client. No trouble. Then you come! I don't want to waste my time! I'm forced to wear an erotic swimsuit that shows a lot of exposure with no way to escape...I'm being penetrated.
