A strap-on is a device used by stories' characters. It consists in a replica of a male cock made from any materials, but preferably flexible and soft or polished. Characters can find it or craft it patiently. It is equipped only by women characters, who can harness it to their waist and wield a replica of penis to pleasure any other character, and typically use it to penetrate them. It can also be sucked. If nasty, strap-on can also be made with a hook fitting in the vagina of the user. In this case, in addition of a waist harness, it is also maintained by the perineal clenching of the strap-on user, and has the potential to pleasure even more the strap-on user through penetration and movements.
