Peter, never thought that you could have too much sex. Now he understands that it can actually happen. Ever since his reverse gangbang with the Sinful Six, he has had a constant and painful erection 24/7. He has tried everything to make it go down but any attempt leads to him getting harder. He even ended up imaging Jamason naked. Which would have worked if he didn't think of if JJ was turned into a woman that he would violate.
Poof
A scantily clad demoness appears in front of Peter.
"... Are you here to help me?"
"Yes, Spider-Man. My name is Mephista. I am the daughter of Mephisto and I could sense your sexual suffering from hell. I decided to come to help you out."
Peter doesn't negotiate with his enemy's children, but he could always make an exception.
"How are you going to help me?"
"You are overloaded on tantric energy with barely any chaotic energy. As a demoness, if we have sex then you will gain some tantric but mostly just chaotic energy. If we do it enough times they will be close enough to not be as painful for you."
"What's the catch?"
"I want you to fuck me every year on this day. Even if you're married to someone."
Normally Peter wouldn't ever make that sort of deal, but he was in serious pain.
"Deal."
They both start kissing each other furiously. Peter strips off Mephista's pants and starts to finger the demoness very fast. Peter moves his head down to lightly bite the woman's clit. Mephista cums over Peter's face.
"Taste like hot sauce."
Peter is too excited to fuck her that he foregoes a blowjob and pulls his member free and lines it up with her cunt.
"Fuck me like your raping me. It will generate more chaotic energy if you commit sins during sex."
Peter nods and starts pounding into the cock hungry bitch. Peter pulls on her nipples and forcefully kisses her, making her taste herself. Peter bites her neck leaving marks.
"To show you belong to me now cunt!"
Mephista cums at Peter making her his own cock sleeve.
After several O's from Mephista, Peter feels his first of many approaching. Peter grips her neck moderately tight and screams.
"Take my seed, Bitch!"
Peter can feel dark thoughts flooding his head as he fucks the Demon Lord's daughter.
Peter turns Mephista around and shoves his cock up her ass without missing a beat.
"Ahhh!" Mephista hasn't ever done anal with a cock so big and felt some serious amounts of pain course through her.
Peter grips the woman's tail and yanks on it like a person would a leash to a bad dog.
"Yes!"
"Quiet slut!"
Peter starts to spank the demoness's cheeks as he fucks her ass. He also tugs her gorgeous black hair back so that she is looking up at the ceiling.
Peter leaves a huge creampie in the woman's ass and after he pulls out forces her to suck him off.
"My pet, can you shapeshift?"
"Yes, master."
Peter pulls out his phone to pull up a picture of a naked woman.
"Turn into her." The arachnid demanded.
"Yes, master."
Suddenly standing in front of Peter Parker is his old classmate Jessica Jones.
"Pretend you are upset with how your husband Luke doesn't have sex with you and you called me to help you out.
She nods at the man's words.
"Oh tell me, Peter. Do you think I am attractive?"
"I think you are beautiful, Jessica."
"Well, Luke hasn't felt the same recently. He's always spending time with his friends and has ignored my needs. That is why I called you here tonight. Please make love to me.
"Of course."
Peter starts kissing 'Jessica' and makes sure to feel all over her soft body.
'Jessica' kisses Peter with passion. Peter slowly sheaths himself into her womanhood. Peter increases the pace and thrust deeper and faster into the woman.
"You should have never married that bitch Luke. He could never satisfy you as much as me."
Peter and 'Jessica' both feel their climaxes coming and cum with each other.
"Mephista, that was great. Can we try a genderswap next? I have the perfect person in mind."
Peter smiles darkly as he is going to fulfill his darkest fantasies with his new pet.

In Hell
Mephisto receives an alert from his iPhone. He finds a video of his daughter getting plowed by Spider-Man.
" Spideeeeerrrrrrrrr!!!!"
Mephisto storms away from his servants into his room for privacy. Mephisto makes sure no demon is nearby and once he confirms he changes his form. He turns into a female form. Mephisto has always been a woman, she just hides it because the system of hell is very sexist and no demon would listen to a female leader. The woman is jealous because she had taken away Peter's marriage with Mary-Jane, but she had agreed to leave him alone.
Mephisto starts masturbating to the man she loves but can't be with as he plows her daughter.
Life can be so cruel.
