An erotic dream induction apparatus includes an inflatable air bladder, such as a rubber balloon, to induce sexual arousal via genital stimulation. The air bladder is brought into contact with either the penis or vagina of the user, and/or is inserted into the anus and/or vagina of the user. In one embodiment, the air bladder is brought into contact with the penis, vagina, and/or anus of the user by being maintained in position near, against, or around the penis, vagina, and/or anus by means of straps or pockets in stimulation underwear, such that when the air bladder is inflated, the air bladder makes contact with at least a portion of the penis, vagina, and/or anus of the user. The air bladder is repeatedly inflated and deflated by means of pumps and/or valves.
