Abstract: An axial elongated main body of a container with flexible material has a filler member of soft and more resilient material filled and fixed in the main body of the container. A penis insertion part is arranged at a substantial central part of the filler member and lubricant agent is coated at the penis insertion part. The penis insertion part has a narrow insertion part and a slack insertion part. The narrow insertion part is provided with a plurality of projections. The massage device so constructed is operated such that a lid, if this is set at the device, is taken off of the device and if the lid is not set at the device, a packaging bag is broken and then lubricant agent is coated on the penis insertion part. Or if the device is coated in advance with lubricant agent, the device may be used as it is.
