Even though I have a girlfriend, I secretly go on a date with my senior coworker Riho. She hugs me whenever she gets the chance, whispers dirty talk, and keeps tempting me with kisses, promising a hotel trip as soon as I get hard. At cafés, arcades, and amusement parks, her natural Kansai accent and aggressive teasing keep me fully erect. She takes control in the hotel, gives me a blowjob at the entrance, rides me hard during intimate sex, and draws me into repeated internal finishes. By the end, she declares me her boyfriend, and I am completely captivated despite knowing the affair is wrong.
