That Saturday

Miles walked through the city in the Spider-Man costume he bought from the store. He turned a few heads on the way over, most people assuming he was a street performer. Once he made it to the tower he took a moment to take it all in before walking through the front door.

"Hey, I'm was told to come here by Spider-Man…" before he could finish that sentence the receptionist pushed a button causing an elevator to open.

"Just push the big 'A' button on the elevator."

Miles walked into the elevator and did as instructed and waited as the elevator took him upwards while he struggled to settle his nerves. The doors opened to a penthouse with Spider-Man sitting on a couch in the middle with Spider-Woman, Captain Marvel and Princess Shuri of Wakanda draped over him and kissing him.

"Hey Miles" Peter said as he got off the couch and walked over to miles with the girls, "you bring what I asked you to?"

"Right here" miles said pulling the notepad and sketch book out of his backpack, handing the sketchbook to Spider-Man.

Spider-Man flipped through the sketchbook "cool designs" he said before handing the sketchbook to Shuri, "think you can work with this, babe?"

"There's plenty to work with, and never call the princess of Wakanda 'babe'." Shuri said as she took the sketchbook and walked off towards the laboratory, "I'll have my prototypes finished in a week."

"Okay Miles, if you'll come with me" Spider-Man said as he escorted Miles to the training room.

"Are you dating two of the Avengers and the princess of Wakanda?" Miles asked, "at the same time?"

"Yeah" Spider-Man admitted, "there's kind of a culture in the superhero community around polyamory and harems."

"And those three are your harem."

"They're part of it, but I have more girlfriends."

"How many?" Miles said shocked.

"Besides the three you just saw? There are five that live with me, three more living on their own, two X-Women, and two that I share with other heroes."

"That's a lot of girls."

"Admittedly my harem is rather big compared to some other heroes, figure it's my spider pheromones making me more attractive."

"Is that going to happen to me?" Miles said half nervously.

"Possibly" Spider-Man said bluntly, "I'll give you advice on that later. Right now I'm going to need test your current skills so I can figure out the learning curve." He handed miles a pair of his old web shooters. "Right now I'm testing your agility and aim, we'll teach you how to swing from webs later."

Miles entered to training room while Spider-Man entered the control room. They spent most of the rest of the day testing what Miles was already capable of, somewhere in the middle they discovered that, besides the powers that Spider-Man possessed, Miles could also turn invisible and fire a close contact venom blast.

"Well that was quite productive, here's some equations I want you to go over, and I'll see you next week." Spider-Man said as he saw Miles off.

"Okay, I'll see you then" Miles said as he headed for the nearest subway station, "have a good week."

"You too!" Spider-Man said as he swung off towards home. Midway through his commute he suddenly found himself caught in electrified bolas and landed on a nearby rooftop, the bolas shut off on their own and Spider-Man looked up to see a woman with white hair and a silver bodysuit.

"Hello Spider-Man." She said in a husky Slavic accent.

"Silver, what's the occasion?"

"You know what this is about, Parker" Silver Sable said as she mounted the wall crawler, "you still owe me a baby." She then proceed to remove both of their pants and shoved her pussy in his face before going down on him herself.

For his part Peter took all of this in stride. Silver Sablinova had a habit of being the most aggressive of all his girlfriends when it came to getting what she wanted and right now she wanted a spider bun in her oven. Peter diligently licked Silver's pussy, while Silver sucked hungrily on his cock. As she slurped and lick along the shaft, she made extra sure to give attention to the glans. Once his cock had reached its maximum size of ten inches, Silver stood up removed the rest of her clothes and impaled herself on his erection. Silver let out a scream and shouted something in Symkarian at the top of her lungs before bouncing up and down on her lover's cock.

"I love it when you talk dirty" Peter said, half joking as he didn't speak Symkarian. He grabbed her arms and pulled her down over him taking her breasts in hand before licking either nipple, "bet you can't wait to have these full of milk, can you? I'll bet it even turns you on. The thought of your tits leaking milk just makes you so wet, doesn't it?"

"Ah" Silver moaned.

"I'm right, aren't I?" Spider-Man said as he slapped her boobs, "your a lactation fetishist, aren't you? That's why you want a baby so bad, isn't it?"

"You're wrong, ah, want this baby so badly because I love you!"

"I love you too Silver" Peter then pulled her into a kiss as he came in her pussy.

The couple lay on the rooftop basking in the afterglow and the light of the moon.

"Once I'm pregnant I'll move in with you and your other concubines."

"Speaking of which, do you want to join us for dinner tonight?"

"That would be wonderful."
