The ritual itself is a lengthy process, taking up to three weeks. One begins by preventing any orgasm, but continuing to expose oneself to arousing material as is possible. Every night, after bathing thoroughly, as one goes to bed, choose to sleep naked and spend a short time with your eyes closed in as dark a room as possible. Take this time to caress yourself as you would wish a lover to, and try to visualize a pair of hands that are not your own in doing so. Try to create a mental image of your lust embodied -the most sexually attractive thing you can imagine(succubi can take the form of tentacle monsters, too, with alterations to this ritual) and attach that image to the caressing hands/appendages. During this quiet time, it could help some to light candles, or incense -I did not find it necessary. This is to continue every night, granting this mental visualization more features, even personality. The lack of orgasm and overexposure to sexual material will be trying on the willpower, but persist -as libido whips your mind into a frenzy, struggle to put that energy into the visualization of your partner.
Beyond that, results are varied. Some are raped in their sleep, waking with bruises and cuts, others wake up with damaged memories, others simply have orgasms while asleep. The ritual itself is merely a catalyst to control the appearance and beckon the coming of a succubus, not a way to determine it's actions.
Granted, this can be screwed up in at least fifteen different ways, result in a tulpa instead of a succubus, or just not work. But hey, experimentation is the flower of knowledge.
