UMD-1003 Unexpected mishap during intimate play!! While practicing with my younger sister, it accidentally slipped in! 12 Karin Kitaoka

Karin is a caring younger sister who looks out for her brothers. Each of her two older brothers has a girlfriend, and both are on good terms with them, but they each have their own unique worries about intimacy.

Brother 1 has a girlfriend, but things are not going well between them. He has trouble with physical closeness and can’t seem to make progress.

Brother 2 has a girlfriend for the first time in his life. He has little experience with women and doesn’t know how to act around girls.

Seeing her brothers struggle, their kind younger sister steps in to give them affectionate guidance. At first, because they are siblings, they only practice in a limited way, but as the situation becomes more intense, things go further than planned. In the end, after holding back for a while, they can no longer resist.
