At his new job, every female employee works in a swimsuit that clings tightly to her breasts and hips. No one distracts him more than his cool, confident trainer Momoka Kagura, whose enormous K-cup breasts strain against the fabric. As she gradually recognizes his hard work, she becomes kinder and lets him get increasingly close to her chest. When his erection makes it impossible to concentrate, she sighs that it cannot be helped and presses those soft, warm breasts against him. The swimsuit-clad office drives him wild, and he becomes desperate to discover what lies beneath the fabric as she repeatedly helps him get off.
