A cap assembly for removable attachment to a non-mechanized masturbation device is provided. The cap assembly comprises at least one moveable extension member, and at least one actuator adapted to move the extension member. The actuator may include a motor. The actuator is adapted to move the extension member in one or more selected directions, such that the extension member can contact an elastomeric gel provided as part of the non-mechanized masturbation device, and move a portion of the elastomeric gel to impart sensation to a user.本發明係提供一種用於可移除式地附接至一非機械化自慰設備的蓋組件。該蓋組件包括至少一可移動的延伸構件、以及至少一適用於移動該延伸構件的致動器。該致動器可包括一馬達。該致動器係適用於在一或多經選定的方向中移動該延伸構件,以使得該延伸構件能接觸到一經提供為該非機械化自慰設備之部分的彈性膠凝體,並將該彈性膠凝體的一部分移動,進而賦予感覺給使用者。
