IPZZ-921 — My senior colleague, Sakai, who trains me at the swimwear company, has a body like a gravure idol when she takes her clothes off, and I get an erection every time I see her trying on swimwear, but my senior colleague is secretly a pervert and gets excited and makes up an excuse to have sex with me.

I got a job at a swimwear company. In an adult video I watched a long time ago, all the employees were wearing swimsuits, so I went to work with my imagination running wild. But the reality was that we had to go to work in suits as usual, which was disappointing. However, I was told there would be a swimsuit fitting, so I immediately tried on some new designs with my mentor, Senior Sakai. Senior Sakai appeared in a swimsuit, and I was surprised to see that she was slim with huge breasts, which was completely unexpected from her clothes! Damn... thinking about erotic things is making me hard...! I hope it all works out!
