Sumire, a married woman who married a serious and kind husband who had a relationship since college and felt happy in the casual daily life of the couple. However, the man of her husband's boss changes her life completely. While my husband was absent, I used my boss's position and forcibly screwed in a meat stick that swelled to the violet and had floating blood vessels. Sumire, who continued to be given pleasure that her husband had never felt, gradually weakened her resistance and began to seek pleasure and meat sticks herself.
