A spiraling tunnel runs through a majority of the Transfer Student masturbator. The entrance is tapered-in for a fast and easy insertion with the overall 3D design giving a tighter sensation. At the beginning flesh-like folds spiral in a roller-coaster track then change mid-way into a helical spiral of nubs. At the very end you will find a vacuum chamber lined with tiny stimulation nubs and by squeezing the air out of this chamber before insertion, the hole will have an increased suction feeling.
The "Baby Skin" material as the name suggest, is soft to the touch while being completely safe. Made in Japan of the highest Japanese quality, fans of spiraling sleeve should consider ToysHeart's Transfer Student Masturbator.
