Nagi, the younger sister, was in love with her older sister Rena. The older sister knew her younger sister's feelings and accepted her affections. Their gentle and sweet kisses gradually became more intense. Because they loved each other, they wanted to do more and more things that felt good. They touched every inch of each other's bodies, licked each other, and made love to each other. They came, came, and were made to come, and the sisters' secret sexual acts were repeated from morning to night.
