"From here on out, I'll give you… the ultimate pleasure with this toy." Nanase, who works in the sales department at an adult goods company, and Togo, who works in the development department, are like cats and dogs. Even today, I was full-on rejected during my presentation and ended up working overtime into the night. For work… I was putting one of Togo's products in my ass when, for some reason, Togo walks in!? "…I'll show you how to use it." Even though I hate him, when Togo's hot hands caress me my mind melts away…!? The exciting love between a sadistic top dog of the development team, and a headstrong, hot and cold beauty!
