Soft tube onacup – Tighten yours to suit. Now with a new soft tube, this onacup gives you complete control over the tightening sensation. Feeling that suits you, controlled by how tightly or how lightly you grip the masturbation cup. Enjoy a wide variety of sensual sensations from rubbing, stroking, pressing, etc. One remarkable feature is the ability to “squeeze out" the onacup after ejaculation.
