A kind of property accessory part, penis simulator and vagina simulator. Property accessory part include a penis simulator and a vagina simulator. Penis simulator includes a cylinder, a pressure detection unit and the first signal transceiving unit. Vagina simulator includes an ontology, a speed detecting unit and one second signal transceiving unit. Cylinder is to be inserted into one of one first user sexual organ. A convergent force of the pressure detection unit to detect sexual organ, and a radial actuation information is exported to apply a radial pressure to one of the second user penis. Ontology has a recess. The insertion being recessed to receive penis. A relative motion of the speed detecting unit to detect second user's relative velocity detecting unit, and export an axial actuation information and one axial movement is generated with the sexual organ of opposite first user.一種性輔助組件、陰莖模擬裝置及陰道模擬裝置。性輔助組件包括一陰莖模擬裝置及一陰道模擬裝置。陰莖模擬裝置包括一柱體、一壓力偵測單元及第一訊號收發單元。陰道模擬裝置包括一本體、一速度偵測單元及一第二訊號收發單元。柱體用以插入一第一使用者之一性器官。壓力偵測單元用以偵測性器官的一收縮力，並輸出一徑向作動資訊以對第二使用者之一陰莖施加一徑向壓力。本體具有一凹陷。凹陷用以接受陰莖的插入。速度偵測單元用以偵測第二使用者相對速度偵測單元的一相對運動，並輸出一軸向作動資訊以相對第一使用者的性器官產生一軸向運動。
