A slightly chubby junior coworker confesses that she has felt miserable since her boyfriend criticized her recent weight gain. Her senior notices that the extra softness also gave her enormous, perhaps K-cup breasts, and lets slip how inviting her body looks. Months later on a company trip, she makes her move, and he accepts, blaming the boyfriend who neglected such an erotic figure. They sneak away to fuck throughout the inn and in a private hot spring, reveling in breasts soft enough for hands to sink into, her bouncing chest and belly, plump mound, and heavy ass driving down with her full weight. A live-action adaptation of Futaworks' CG comic, which sold more than 68,000 copies.
