The vagina-shaped element includes an opening at a first end of the substantially hollow cylindrical body to receive a male genital organ therein. The adult toy includes a chamber arranged between the substantially hollow cylindrical body and the vagina-shaped element, with the chamber surrounding the vagina-shaped element, and further includes an air pump arranged towards a second end of the substantially hollow cylindrical body. The air pump is disposed in fluid communication with an ambient atmosphere and the chamber and provides an air pressure inside the chamber. The chamber inflates and deflates based on the air pressure therein to cause the vagina-shaped element to compress and decompress to stimulate the male genital organ received therein. ## Claims ### Claim 1 An adult toy, comprising: a substantially hollow cylindrical body having a first end and a second end; a vagina-shaped element arranged inside the substantially hollow cylindrical body, the vagina-shaped element providing an opening at the first end of the substantially hollow cylindrical body to receive a male genital organ therein; a flexible bag arranged between the substantially hollow cylindrical body and the vagina-shaped element, the flexible bag being configured with a space defining a chamber surrounding the vagina-shaped element; and an air pump arranged towards the second end of the substantially hollow cylindrical body, the air pump being disposed in fluid communication with an ambient atmosphere and the chamber and being configured to provide an air pressure inside the chamber, wherein the chamber is adapted to inflate and deflate based on the air pressure therein to cause the vagina-shaped element to compress and decompress to stimulate the male genital organ received therein. ### Claim 2 (depends on 1) The adult toy as claimed in claim 1, wherein the opening of the vagina-shaped element includes at least one of a mesh, a gauze, and a sponge and is of a labyrinth form. ### Claim 3 (depends on 1) The adult toy as claimed in claim 1, further comprising: a cover plate arranged at the second end of the substantially hollow cylindrical body, the cover plate being provided with: a first air-hole adapted to be disposed in fluid communication with the chamber, to vent out pressurized air therefrom, and a third air-hole adapted to be disposed in fluid communication with the air pump, to allow the air pump to draw air from the ambient atmosphere. ### Claim 4 (depends on 3) The adult toy as claimed in claim 3, further comprising: a first valve provided on the chamber such that the first valve is disposed in an open position to allow for venting out pressurized air from the chamber when pushed; and a first outlet pipe aligned with the first valve and arranged with respect to the first air-hole to translate therein, wherein the first outlet pipe is adapted to be pushed to move through the first air-hole so as to push the first valve. ### Claim 5 (depends on 4) The adult toy as claimed in claim 4, further comprising a controller configured to control opening and closing of the first valve for regulating the air pressure inside the chamber. ### Claim 6 (depends on 1) The adult toy as claimed in claim 1, wherein the vagina-shaped element extends partially along a length of the substantially hollow cylindrical body between the first end and the second end. ### Claim 7 (depends on 1) The adult toy as claimed in claim 1, further comprising one or more stimulation devices arranged inside the substantially hollow cylindrical body and configured to induce stimulations to walls of the vagina-shaped element to stimulate the male genital organ received therein. ### Claim 8 (depends on 7) The adult toy as claimed in claim 7, wherein the one or more stimulation devices comprises at least one of a gel, a metal foil, other electrically and thermally conductive materials, or a vibrating device. ### Claim 9 (depends on 8) The adult toy as claimed in claim 8, wherein the vagina-shaped element has channels built in to its structure to use the at least one of the gel or the metal foil or the other electrically or thermally conductive materials or the vibrating device to induce stimuli to specific regions on a surface of the male genital organ received therein. ### Claim 10 (depends on 1) The adult toy as claimed in claim 1, further comprising at least one button for activating the adult toy and regulating the air pressure inside the chamber. ### Claim 11 (depends on 1) The adult toy as claimed in claim 1, wherein the adult toy is configured to provide a sensory feedback to a user to indicate real-time strength, pattern, and other status information of stimulations of the adult toy. ### Claim 12 An adult toy, comprising: a substantially hollow cylindrical body having a first end and a second end; a vagina-shaped element arranged inside the substantially hollow cylindrical body, the vagina-shaped element providing an opening at the first end of the substantially hollow cylindrical body to receive a male genital organ therein; a chamber arranged between the substantially hollow cylindrical body and the vagina-shaped element, the chamber surrounding the vagina-shaped element; and an air pump arranged towards the second end of the substantially hollow cylindrical body, the air pump being disposed in fluid communication with an ambient atmosphere and the chamber and being configured to provide an air pressure inside the chamber, wherein: the chamber is adapted to inflate and deflate based on the air pressure therein to cause the vagina-shaped element to compress and decompress to stimulate the male genital organ received therein, and the adult toy is configured to provide a sensory feedback to a user to indicate real-time strength, pattern, and other status information of stimulations of the adult toy.
