Imagine a movie where Peter only loves Mary the transwoman, but she doesn't give a fuck about him, then he succumbs to depression and starts asking out random guys and girls in metros and buses, but everyone rejects him and he gets banned from entering public transport. So he becomes evil, eats a spider, gets his Spiderman powers, and uses them to do evil. Like webbing random people on dark alleys, hehehe. Finally he is beaten by Doctor Octo-Pussy who, as a person who has a good and loving relationship with his wife and doesn't fuck everything that moves, teaches him the meaning of true love. Spiderman first tries to steal O-pussy's tenctacles, but after being beaten by him, loses his Spiderman web powers by ejaculating all the webbing inside him out at once, and becomes an eunuch. Now that he is a powerless eunuch he can't resist (I don't mean romantically) Octo anymore, so he forfeits, and starts his healing process, he no longer desires other people and he has no superpowers anymore, and starts living like a regular guy and studying science. Later he meets Otto again, Otto (who never found out Parker is Spiderman), thinks Peter has potential to be a good scientist who can invent many great things, and hires Peter as his apprentice. The End.
The second movie is about Otto one day 8 years later on a really drunken party night remembering that Spiderman had wanted to steal his "tentacles" to do naughty things. So he starts doing naughty things with the tentacles in public, and now it's Peter who has to use his Eunuch powers to defeat lust once and for all. Octo's wife divorces him, Peter marries her and finally when Peter has a chance to get consentual sex, he refuses it, since he prefers being a good Eunuch. Tying nicely with the first movie where he lusted after Mary for 5 years and after getting rejected started trying to get everyone.
What happens to Octo? Well, heeeee........ I don't know. Maybe he gets thrown into a lake, and Peter thinks he drowned, but he actually drifted along the river, until he was found by Mary and her newest Chad friend. Octo got his head hit (in the fight, or hit a river rock), has an amnesia, doesn't remember Peter, Spidy or his wife anymore and starts a new life in which he helps (consentually) people with disabilities with his tenctacle arms.
