DETAILED DESCRIPTION OF THE INVENTION

(7) FIGS. 1 and 2 illustrate an example of a mutual sexual stimulation device 10 embodying the objectives and advantages described herein. In the example shown in FIGS. 1 and 2, the mutual sexual stimulation device 10 includes a molded, one-piece, silicone body 12, including a front face 14 in which a pair of offset, adjacent openings 16 are located. The openings 16 lead to a pair of channels 18 that converge to a chamber 32 (FIG. 3) that runs internally along the length of the body 12, as described further herein. A rear face 30 includes a third opening 34 (FIGS. 3 and 4A-4C). The body 12 may further include one or more handles 20 or other gripping mechanisms to improve the users' ability to position and manipulate the device in use.

(8) Although shown as a one-piece, silicone body 12, the mutual sexual stimulation device 10 can be made from any one or more materials appropriate for use as a sexual aid. The preferred material is medical-grade, chemically inert silicone, which is hypoallergenic and safe for use as described herein. It is a non-porous material that is easy to clean and does not wear out easily. It is a strong, dense material, but it also warms to body heat, which may be more comfortable and natural feeling for the users than other suitable materials may be. However, it is contemplated that one or more portions of the mutual sexual stimulation device 10 may be formed from one or more thermoplastic elastomers, soft plastics, rubbers, and the like. For instance, in the example shown in FIG. 3, the mutual sexual stimulation device 10 is a two-piece construction that includes an outer sleeve 36 surrounding the silicone body 12. The outer sleeve 36 may be made from a different material as the body 12, for example, a more rigid material (or a more rigid formulation of the same material) to provide support and structure to the device 10 and improve the stability of and compression of the penises within the chamber 32. Similarly, the embodiment shown in FIG. 1 may be a two-piece construction, with the portion of the mutual sexual stimulation device 10 including the handles 20 being a part of the outer sleeve 36 and the body 12 being the portion of the mutual sexual stimulation device within the outer sleeve 36.

(9) In addition, one or more portions of the body 12 or sleeve 36 may be formed from materials incorporating water-filled cavities, gel-filled cavities, air-filled cavities, and the like. Similarly, the mutual sexual stimulation device 10 may incorporate one or more vibrating motors to enhance the sensations experienced in using the device. Between variations in materials and construction techniques, such as including water-filled cavities, the stretching, compression, heat regulation, and other physical characteristics of the device 10 may be adapted to meet a wide range of personal preferences.

(10) As shown in FIG. 2, the openings 16 lead to channels 18 and each opening 16 provides an entry point for a penis. The openings 16 in this embodiment are separated by a barrier 22 that spaces the openings 16 and provides isolation between the channels 18 near the openings 16, but partially merge further inside the body to form the chamber 32 (FIG. 3). The openings 16 are located in contoured, recessed receiving areas 24 of the body 12, that provide space for a user to comfortable fit close against the mutual sexual stimulation device 10. The channels 18 shown have textured interior surfaces 26; in this example, raised bumps. Although shown as bumps, the interior surfaces 26 may include and combination of rings, ribs, ridges, channels, beads, bristles, and the like. Alternatively, the interior surfaces 26 may be smooth and non-textured.

(11) In the embodiment shown in FIGS. 1 and 2, the face 14 of the body 12 is designed for penetration includes generally smooth and rounded features, which helps to make the device 10 more comfortable to the users, though the mutual sexual stimulation device 10 may be embodied in a variety of shapes, including generally rectangular, ovular, spherical, and on. Additionally, the embodiment shown in FIGS. 1 and 2 may be made of one integral piece of material (e.g., silicone) or from two separate materials (e.g., a silicone body 12 and thermoplastic elastomer outer sleeve 36).

(12) Turning to FIG. 3, a cross-sectional view of the mutual sexual stimulation device 10 details one example of the internal form. The embodiment shown in FIG. 3 is a two-piece mutual sexual stimulation device 10, including a body 12 and an outer sleeve 36. By employing a multi-piece device 10, varied materials can be used for the body 12 and the outer sleeve 36 to enhance the respective properties of each. For example, the body 12 may be made from a softer and more elastic material to improve comfort, while the outer sleeve 36 is formed from a less soft (though still comfortable for use against the body) and less elastic material to resist the expansion of the inner body 12 and to improve compression within the chamber 32. As additionally shown, the outer sleeve 36 is thicker to provide more rigidity and compression in the section of the body 12 where the penis heads rub together. Comfort and other performance variables may be intentionally affected by varying the thicknesses and the materials of the device 10.

(13) As shown in FIG. 3, the interior surfaces 26 the channels 18 are textured along their lengths. The textured interior surfaces 26 include both ridges and bumps. In addition, it is easy to see in this view that longitudinal axis of each of the offset channels 18 are furthest apart at the openings 16 and converge along the length of the mutual sexual stimulation device 10 (i.e., the channels angle towards each other as they approach the third opening 34).

(14) The angle between longitudinal axis of each channel 18 shown in FIG. 3 is approximately 8 degrees (i.e., each channel 18 is at an angle of approximately 4 degrees with respect to the centerline of the device 10). However, it is contemplated that the arrangement of the openings 16 may be adapted such that the angle may be any of a wide range of angles. For example, in some instances, the angle may be anywhere between 0 degrees and 30 degrees. In other examples, the angle may be anywhere between 5 degrees and 15 degrees.

(15) The barrier 22 spaces the openings 16 and the channels 18, but only for a short distance into the body 12 at which point the two channels 18 converge into a single chamber 32 in which, in use, the underside of each users' penis contacts the underside of the other user's penis, especially towards the head of each penis. One advantage of the barrier 22 is that it helps facilitate a feeling of penetration as each user enters the device 10. In this example, the barrier 22 extends into the body 12 approximately one inch, providing stability to the openings 16, separation of the channels 18 near the openings 16, but without interfering with the contact between penises further in the chamber 32. However, it is contemplated that the barrier 22 may extend a greater or lesser distance into the body 12. For example, in some embodiments, the barrier 22 may extend between one quarter of an inch to two inches into the body 12.

(16) In the embodiment shown in FIG. 3, the converging channels 18 approximately form a figure eight, or lemniscate, shape. This lemniscate shape helps to keep the penises aligned and in contact, specifically to promote contact along the underside of the head of each penis. In other examples of the mutual sexual stimulation device 10, the entire length of the channels 18 may be a lemniscate shape, including the openings 16, which in that embodiment would appear to be a single opening 16. As further shown, FIG. 3 shows that there is a third opening 34 in the body 12, as discussed further below.

(17) In an embodiment of the mutual sexual stimulation device 10, the body 12 is approximately 7.25 inches in length with channel diameters of approximately two-thirds of an inch near the openings 16 and tapering to smaller diameters away from the openings 16 and into the chamber 32. The reduction in diameter is intended to increase the compressive forces on the penises in the chamber 32. Variations of the dimensions may be used. In fact, various sizes of the mutual sexual stimulation device 10 may be provided to more closely match the anatomy of the users. In one contemplated example, the mutual sexual stimulation device 10 is custom made to match the dimensions provided by the users (e.g., one channel is a different size than the other). As such, each opening 16 and each channel 18 may be a unique size. In addition, the openings 16 may be staggered at various depths in the body 12 to assist in aligning the heads of the penises in use.

(18) FIGS. 4A-4C show variations of a two-piece embodiment of the mutual sexual stimulation device 10. As shown in FIG. 4, the body 12 of the device 10 includes channels 18 that extend through the entire length of the body 12 partially merging to provide a third opening 34 opposite of the openings 16 and the barrier 22 along the front face 14. The third opening 34 is useful for allowing semen, lubricant, and other substances to escape the body 12 and/or for the chamber 32 to be more easily cleaned. The third opening 34 may also help to prevent the formation of a low-pressure vacuum when the device 10 is in use and permit the easy application of lubricant.

(19) FIGS. 4A-4C provide views that help to illustrate the point that more the interior surfaces 26 pinch in to create a figure eight shape in the chamber 32 the greater the positional stability of the genitalia in the chamber 32, and the less the interior surfaces 26 pinch in to create a figure eight shape in the chamber 32 the more room there is for contact between the genitals. FIG. 4B demonstrates an embodiment of the device 10 which has no pinch in, with the chamber 32 forming a more ovular shape. Such a chamber 32 shape enables greater contact between user's genitals at the cost of positional stability. FIG. 4C illustrates yet another embodiment of the device, this time with the interior surfaces 26 highly pinched in (i.e., more pinched in than what is seen in FIG. 4A). This embodiment increases positional stability and reduces overall genital contact. As shown, variations in the shape of the chamber 32 may be used to optimize the performance of the device 10. In addition, the amount of pinching and the size of the chambers during use of the product will depend, at least in part, on the girth of the penises in the device and how much they cause the chamber 32 to expand.

(20) As further shown in FIGS. 4A-4C, the body 12 is intentionally thicker on the sides of the body 12 than the top and bottom. The thickness further helps with the stability of the penises in the chamber 32 by keeping them aligned and maximizing contact. This is one reason that the mutual sexual stimulation device 10 may preferably be block-shaped. Another reason the mutual sexual stimulation device 10 may preferably be a block shape is that having flat sides lie against each partners's body in use prevents the device 10 from rolling.

(21) FIG. 5 shows another example of a mutual sexual stimulation device 10. In the example shown in FIG. 5, an outer sleeve 36 forms a second piece of a two-piece embodiment of the mutual sexual stimulation device 10. As shown in FIG. 5, the outer sleeve 36 may be a more rigid material that surrounds the body 12 providing greater compression for the penises, as described above. In this embodiment, the body 12 may be made from a softer and more elastic material, while the outer sleeve 36 is formed from a less soft (though still comfortable for use against the body) and less elastic material to improve compression. In another embodiment, the sleeve's inner wall may also form a figure eight to increase the positional stability of the penises.

(22) It can be seen through a comparison of FIGS. 3-5 that the thickness and shape of the outer sleeve 36 may vary. For example, the outer sleeve 36 is thicker in FIGS. 3-4C than the outer sleeve 36 shown in FIG. 5. It will be understood based on the descriptions and drawings provide herein that the proportions and shape of the body 12 and the outer sleeve 36 may take many forms.

(23) It should be noted that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages.
