A masturbation sleeve is a flexible tube used to enclose the penis and enhance masturbation. Masturbation sleeves have one or two openings (on one end or either end) and may include texture to increase sensation. Masturbation sleeves are offered in a variety of materials, such as plastic, silicone, and thermoplastic elastomers (TPE), a rubber-like material.
Some masturbation sleeves are designed to look and feel like a vagina, which is why they are often called pocket pussies.
