While house hunting with my fiancée at a real estate agency, the agent Kasumi turned out to be an unexpectedly stunning beauty, with soft-looking large breasts and a glimpse of cleavage that made my heart race. Though I knew I should restrain myself for our upcoming new life together, the moment she subtly pressed against me and reached for my crotch during the viewing, my rationality vanished. Her seductive words, 'I think you're really attractive as a man,' completely captivated me, leading to a secret affair. In the empty room, her cowgirl position with her ample hips created lewd piston sounds that echoed, and the fear of being caught only heightened the excitement. This work masterfully portrays the temptations hidden in everyday moments, with a drama that intertwines guilt and pleasure, leaving a lasting impression as a true masterpiece.
