Isekai wo Denma dake de Ikinuku!!

While carrying suspicious adult toys, Kenji is run over by a car. "Will I die a virgin?" he thinks as he fades out. At that moment, he reincarnates in another world. Standing before him is a beautiful female knight. In his hand, he is not holding a sword...rather, it's an electric vibrator.

This is the rise of one man and his vibrator in another world.
