From the R&D boffins at the mega-selling Japanese adult brand, the Toy's Heart Cup Soft is a convenient cup-style masturbator that comes lubricated for ease of use. The hole is cased in a special urethane foam material that maximizes the pressure you feel inside, enhancing the sensations of the slightly undulating vagina with varied wall textures.
The cup features a "moisture lid" to prevent the inner lube from drying out, plus there's a hole on the other end that functions like a valve that you can cover with a finger to boost the vacuum.
