I used to feel self-conscious about my body and was passive in sex, especially with my petite and thin husband. However, Takahashi-kun, who is my husband's subordinate, has always been looking at me with a lustful gaze. Tempted by the devil, I invited him, and he was enthusiastic... His tight, youthful genitals were very different from my husband's. Moreover, he fully accepted my insecurities. I couldn't help but want to indulge more, so I suggested he become my exclusive cunnilingus partner, and he readily agreed. From then on, whether my husband was there or not... No, rather, his presence turned me on even more. Right, Takahashi-kun!
