Peter Parker never really knew the full extent of his powers, how much “spider” was in the “man”.
Turns out, he was only buying time before the full effects of his transformation into tour friendly neighbourhood hero set in. On the eve of his 21st birthday, surrounded by family and friends, the changes set in.
Being late to his own celebrations was not like him, so the Avengers decided at least one should investigate. Tony, already being drunk, wasn’t a good fit so Thor instead offered his assistance.
He took the elevator down to Peter’s floor and heard the unmistakeable sound of needy moans and the squelch of juices. At first he thought Peter might have brought a woman down, but peering around the corner saw the younger man legs spread and hands finding the soft wet folds of womanhood between his legs.
Surprised and obviously interested, Thor approached. Peter squeaked in surprise. “Th-Thor! I don’t, don’t know what’s ha-PPENING MMMMHHHH!”
His words turned to moans as his hands couldn’t stop playing with his pussy, offering a gush of juices rewarding Peter for finding his g-spot for the first time.
Thor smirked, removing his clothes and ordering FRIDAY to keep the floor locked. He first kneeled between Peter’s legs, worming his surprisingly long tongue deep inside Peter’s pussy. He moaned and gripped Thor’s hair, grinding his hips into the God’s face as he squirted hard.
“Th-Thor! Ohhhh g-god- Daddyyyy!” He screamed, voice cracking as he drenched the handsome features. Thor pulled up, licking his lips as he lined up the true replacement for mjolnir, all 15in of the Fertility God lined up with his quivering lips and plunged in, sending Peter into orgasm after orgasm as the fat mushroom head sent shocks deep inside.
Their trust wasn’t even that long, three minutes at most of Thor pounding viciously at Peter’s cunt and said Superhero nearly passing out from the sheer pleasure. It wasn’t until Thor sought a more pitiful route that he made himself cum early; dumping his fat balls’ load into the hungry womb of Spider-Man.
He managed to get Peter lucid and dressed, materialising a ceremonial plug from one of Asgard’s many vaults around the cosmos and slipped it into Peter, ensuring not a drop of his godly seed would be wasted.
Now, Spider-Man stands on the rooftops of Manhattan, peering down at the city streets with a godly helper at his side, surveying the streets for the last time in at minimum a few years as Thor wants to spirit him away to Idunn, give him a golden apple of immortality, and make sure he can handle the birth of three little Demi-Gods into the world.
He snapped one final picture for tomorrow’s editorial, positive that both his identity and status at the God of Thunder’s new bride would make international headlines. They moved to a train station, well lit as a late train began to zoom past. The camera was in position and snapped an image as Peter took off his mask and Thor’s lightning illuminated the cloudy sky.
Peter smiled, depositing the camera into a bag ready to be dropped off to the news station. He smiled at the God of Thunder, who leant down to kiss him and pick him up into a bridal position.
“You are so big, my beloved. Big with my kin, you will be even more beautiful as you progress.”
Peter snorted. “Yeah, I’ll be somewhere between beach ball and tyre-“ he began, looking Thor in the eyes. “But I couldn’t be happier it’s with you.”
They took off into the night, news of the Spider-Man and Thor pregnancy took the world by storm and their wedding and honeymoon, the galaxy.
