Unwitting man turns table on ancient succubus

A young man was browsing a thrift store looking for retro video game cartridges when he came across an old brass oil lamp. It looked like a genie lamp out of a story, so he grabbed it as a joke. A few days later when fiddling around with the lamp, he accidentally releases a succubus. The succubus' name is Astrid. She is tall with long blonde hair, with a soft but athletic body, and generous breasts, hips, and butt. She also has a red tail, horns, and wings. Astrid introduces herself and immediately tries to work her magic and seduce the young man. Unbeknownst to either Astrid or the protagonist, he seems to be almost completely immune to her magic. When he realizes what she is, he understandably declines her invitation for sex. This is incredibly perplexing to Astrid as she's never had a man deny her before. As a succubus, Astrid needs to feed on human sexual energy in order to survive. She has been tied to the lamp for over two thousand years since she was imprisoned there by an ancient sorcerer as a weapon he intended to use against a rival, but was forgotten when the rivalry ended. The enchantment on the lamp only allows her out when someone rubs the lamp, and only long enough to drain whoever rubbed the lamp to death. Normally, once she drains a person, she gets sucked back into the lamp and put into a kind of stasis until the next person lets her out. However, because our protagonist is immune to her hypnotic seduction, she ends up out of the lamp for an extended period of time and begins to get hungrier and hungrier. She is naturally quite dominant, taking the energy she needs from the men who rub the lamp, but as she gets hungrier for energy she becomes more submissive and cock-hungry. Over time as the relationship develops with the protagonist, the relationship can go a variety of different ways. The man can willingly agree to become her submissive and feed her energy all the time whenever she wants. Astrid can become the man's loving submissive, with the man keeping her fed and happy in her servitude but allowing her real personality to continue to shine. They can develop a loving relationship of mutual trust. Or the man can keep her starving and cock-hungry all the time and turn her into a desperate submissive sex slave. Whatever strange magic protects the protagonist from her seduction also protects him from any other physical or magical attacks she tries to throw at him. He is also immune to being drained by Astrid, though he can't know this until he experiments somewhat and tries to give her some sexual energy, and he doesn't know why. Astrid can gain energy from their encounters when he specifically tries to give her energy, but he doesn't seem to be negatively affected by the encounter. The only explanation that they can come up with is that somehow he produces so much sexual energy that Astrid filling herself completely doesn't even put a dent in his reserves, and because he can control when he actually releases energy, he also has some control over how much actually gets released. Astrid's magic does seem to have some effect on the man though. Over time he notices his average cock and balls begin to get bigger and bigger, and he begins to produce more and more cum. Over the course of months or years he'll reach truly ridiculous proportions and begin to release impossibly large loads. The enchantment on the lamp only allows Astrid to move about 15 feet away from the lamp at any time, and doesn't allow her to touch or move the lamp in any way, allowing the protagonist to control her location. Once Astrid and the man develop their relationship, she can teach him how to summon more succubi to either keep Astrid company, join their relationship, or to join his harem. Astrid doesn't know how the magic that keeps her chained to the lamp works, but the man may be able to research and discover that as well to eventually free Astrid, or alternatively, enslave more succubi.
