My germaphobic sister asked, "Will you let me practice kissing with you?" We kissed for a week before our wedding. Nene Yoshitaka, a woman who has never been kissed in her life, and who only wears a rubber for blow jobs and sex.

Nene's soon-to-be-married older sister, Nene, is so germaphobic that she is unable to kiss her fiancé, Izumi. Fearing that her wedding kiss will not go well, she asks her younger brother Tomoki to be her kissing practice partner. Will Nene be able to kiss Izumi successfully, and what about her relationship with Tomoki? Tongues entwine, saliva mixes with each other, and their kissing practice becomes serious before they know it. Forbidden incestuous NTR sex.
