Themes: Master/Pet, Tentacle Sex, Breeding
Summary: Part 2 of Tentacles & Subs (originally named Tentacles & Red Heads). Whenever Peter talks about this Gwen from another universe, its obvious to MJ that he wants to fuck her. Peter himself doesn't even seem to realize it, but MJ has a sixth sense for these kinds of things. Far from being jealous, the red head is eager to help make it happen. She can imagine nothing better than feeding another woman to her beloved master's insatiable lust.
-x-X-x-
“F-Fuck. This is such a bad idea…”
Letting out a particularly perverse little giggle, Mary Jane Watson shakes her head, nuzzling into the crook of Gwen Stacy’s neck as she feels up the slightly younger woman. She’s not their universe’s Gwen, but rather a Gwen Stacy from a universe where she got the spider powers and Peter didn’t. As a result, the timelines are a little out of whack. Gwen is a few years younger than MJ and her beloved Master.
“And why’s that, darling?”
Moaning, squirming in MJ’s grasp, Gwen shivers as she stares down at where the red head’s hands are working up and down her naked body.
“I-It’s not right… I shouldn’t… I shouldn’t be here…”
Humming, Mary Jane pinches Gwen’s nipples between her fingers, grinning wickedly as the young blond squeaks.
“Why not? You love Peter. I love Peter. I don’t see anything wrong with sharing. Don’t you want to be with him?”
Gwen whimpers, shivering under MJ’s touch. Her entire body is alight with sensation, her nubile but also toned frame bucking in Mary Jane’s grasp. And yet, she doesn’t try to get away. The red head would know if she were actually trying to escape, considering Gwen had powers and MJ didn’t. She could have easily broken out of her hold, but that was the kicker. She didn’t WANT to.
“I-I loved… m-my Peter. I don’t want… your Peter.”
One hand slides down off of Gwen’s chest and moves betwixt her legs. MJ scoffs as she begins to finger the blonde right then and there.
“He’s not MY Peter, darling. Don’t get it twisted now. I’m his pet, not the other way around.”
Gwen grows even redder at the reminder, stuttering and stammering in response.
“Y-You know w-what I m-meant!”
Giggling, MJ nods, nuzzling some more into Gwen’s body as she does so.
“Heh, yeah. You’re just too fun to tease. Don’t lie to me now, Gwen. Peter might not realize it yet, but there’s electricity between the two of you. He thinks the world of you. He thinks you’re all that and a bag of chips. And you look up to him, don’t you?”
Gwen moans, still trying to deny it.
“I s-see him as a mentor. It’s not like THAT! He’s-!”
She suddenly cuts herself off mid-word, but MJ knows that there’s no reason for Gwen to do so… unless her superior hearing has allowed the young woman to pick up something Mary Jane can’t. Eyes lighting up, the red head licks her lips.
“He’s coming, isn’t he? He’s almost home. He has no idea you’re here, Gwen. If you don’t want this, now is the time to break free and slip away~”
She means it too. She’d never force anything on Gwen. She can’t. Mary Jane is literally nothing but a kept woman. She’s her Master’s pet, his fuck toy. By comparison, Gwen Stacy, or at least this version of her, is a bonafide superheroine. If she wanted to escape, she could in an instant. If she wanted for Peter not to see her like this… then he never would.
In the end, Gwen hesitates, shivering and shaking until finally, it’s too late for her to escape. The window to the bedroom slides open and Spider-Man slips inside. Peter, dressed in all black, pauses for a moment as he looks to the spot on the floor where MJ would normally be waiting for him. When he doesn’t see her there, he slides his gaze to the left, where she and Gwen are currently laid out on the bed.
The mask bubbles for a moment before pulling back, revealing Peter’s features. His eyes are dark as her brown-haired Master looks at them both, expression unreadable.
“… What’s all this then?”
Grinning wickedly, licking her lips in a salacious manner, Mary Jane wiggles from where she’s positioned beneath Gwen. Gwen, meanwhile, whimpers from where she’s position on top of MJ. There are certainly more compromising positions than this one that Peter could have found them in, but not many.
Even still, it’s a position MJ has chosen for a very specific reason. There’s a certain sort of presentation to it that she hopes will appeal to her Master. Yes, Peter has just caught them in bed together. But there’s no denying that Mary Jane is showing Gwen off like a piece of meat. Everything about what she’s doing to the younger blonde in this moment positively SCREAMS ‘here you go, have at her’.
But of course, her Master has asked her a question, and MJ doesn’t hesitate to answer honestly.
“I’ve seen how you’ve looked at her, sir. And I’ve listened to you talk about her as well. I knew you wanted her… just as I knew she wanted you. She’s ready for you, Master. She’s ready to become your woman, just like me.”
Peter’s eyes flash and his nostrils flare. He takes an immediate step towards the bed before seeming to catch himself. Mary Jane can tell that he wants to act right then and there. That he’s already primed to do something. And yet, he holds himself back and looks to Gwen instead.
“… Is this true?”
Moment of truth. If Gwen wants to, she can still back out. Though they’re far past the point where she could have backed out without it resulting in serious backlash for Mary Jane. Of course, even if Gwen HAD fled before Peter could have arrived, MJ would still have had to explain to her Master why the younger woman’s smell was all over the bed and why-
“Y-Yes.”
Oh! MJ’s eyes light up and the red head has to hold back a squeal as Gwen finally admits the truth. The last vestiges of reluctance melt away from the gorgeous, naked superheroine’s body as she trembles in Mary Jane’s grasp. She’s so damn ready it’s not even funny. Peter seems to agree, because he takes one long look at the both of them… and leaps on the bed.
Gwen squeaks and MJ giggles as Peter is suddenly on top of them both. One of his hands grabs Mary Jane by her red hair, yanking her head up and around.
“You’re a bad, bad girl, Pet. I’ll punish you later.”
Shuddering at the promise, MJ moans.
“Mm, yessir~”
At the same time, Peter’s other hand has come up to grab Gwen by the jaw. His thumb finds her lips and pushes in past them into her willing mouth. She shivers but dutifully sucks at his digit as she stares up into his eyes. For a long moment, he just looks at them both… then, he nods. From there, things rapidly escalate. The way MJ is holding Gwen, her legs are already spread. As such, Peter doesn’t really have to do anything but let his massive, alien member protrude from his living suit.
Gwen’s eyes catch sight of it and go wide as she stares down at his huge, fat cock. The young woman knew about Peter’s relationship with his symbiote, of course. She’d warned them that in her timeline, the symbiote had paired itself with a nastier individual, someone who turned the alien intelligence bad. Obviously, Peter was different. He was a better influence.
… Or maybe, the symbiote was simply getting its darker impulses taken care of in a different way. In the end, it doesn’t matter. The bulbous alien shaft presses into Gwen’s cunt and a moment later Peter thrusts his hips forward, spearing the young blonde on his cock.
Gwen squeals loudly as her eyes flutter and threaten to roll back in her head. Now that Peter is inside of her, MJ drops all pretenses, happily acting as a bed for her Master to fuck Gwen upon even while she whispers sweet nothings in the blonde’s ear.
“There it is, Gwen. Master’s cock. So big, so thick, so filling. Don’t you love it?”
“Yeeeesh~”
Already slurring her words. So cute! MJ giggles, nibbling at one of Gwen’s earlobes.
“Then shouldn’t you be asking for more?”
Peter is quiet as he watches this byplay, though he’s not idle. His cock slides in and out of Gwen’s flexing cunt, and MJ can only imagine how hot and wet and tight the blonde heroine is. Gwen, meanwhile, whimpers before taking the red head’s words to heart.
“P-Please… please fuck me more!”
Hm, seven out of ten in terms of volume and follow-through. She’s just missing one thing. Luckily for her, she has Big Sis MJ to help her out!
“That’s not it, Gwen. You have to ask properly. Repeat after me. ‘Please stir up my insides more with your big fat cock, Master!’.”
There’s a pause at that, and MJ can tell Gwen has gone bright red, even redder than she was before. For a moment, she doesn’t know if she’s gone too far. But then…
“Please s-stir up my insides more with your b-big fat cock… Master!”
Word for word. Mary Jane can’t help but grin a wide, wicked grin as Peter chuckles and gives Gwen what she asked for. Continuing to fuck her nonstop, pounding away at her cunt, their Master gives Gwen the fuck of her life. MJ watches with an expression of pure, honest glee on her face. She hadn’t been lying when she’d told Gwen that Peter wasn’t hers earlier. It was completely true. She was Peter’s, but Peter… Peter was her Master. And he could do whatever he wanted and fuck whoever he wanted.
Of course, she wasn’t sure even her Master had understood how deep her loyalty went until now. He likely never would have taken that final step and started a carnal relationship with Gwen if MJ hadn’t forced things. Or maybe he would have, but out of some misplaced sense of guilt, he would have kept it a secret from MJ.
The idea of Peter having an affair with another woman was laughable. Not because MJ thought her position was unassailable, but because MJ would never want Peter to think he had to lie to her about such a thing in the first place. He could fuck anyone. She wouldn’t care. So long as she got to be his sexy, slutty little red-haired Pet.
As things intensify, Peter lets out a growl… and then the mask is back. Spider-Man looms over them both and MJ’s eyes twinkle as she knows what comes next. His hand comes up to her mouth this time, and his thumb presses against her lips. MJ lets him press right in, even as she feels his digit grow and expand, turning from a thumb into a full-blown tentacle. As he begins to face fuck her with the expanded digit, MJ gurgles and chokes, gagging on the tentacle.
At the same time, Gwen squeaks in her arms as another set of tentacles forms from Peter’s hips. Two of them go to MJ’s orifices, punching into her cunt and ass respectively without so much as a ‘by your leave’. However, the third tentacle doesn’t touch MJ… instead, it slips in between the red head and Gwen, and begins prodding at the blonde’s asshole.
Shivering, Gwen finds herself gasping for breath as she experiences her first DP at her new Master’s hands. Well, not hands. Appendages. She moans as their Master’s other hand spreads over her tits, his fingers elongating into tentacles there as well. The appendages wrap around Gwen’s breasts, with two of them suction-cupping over her nipples, splitting into mouths with feelers that drive Gwen absolutely wild.
Spider-Man has never been more alien than in this moment, MJ idly notes as she sucks at the tentacle in her mouth. But then to be fair, she’s never arranged for a threesome for him before this moment either. Even as he pounds Gwen harder and faster with his actual phallus, his tentacles are going to town on both of them at the same time.
It’s as though he’s obsessed with making sure neither of them get left out… even for a second. It’s quite admirable, and MJ can’t help but let out muffled moan after muffled moan as she shudders her way through orgasms again and again. Gwen isn’t much better. The younger blonde is sandwiched between the two of them. She has been all this time. But she wasn’t getting fucked in both of her lower holes before.
One last tentacle protrudes out of their Master’s body, dangling itself right in front of Gwen’s face. Her eyes go crossed and her mouth opens wide as her tongue lolls out in open invitation. With that, the tentacle thrusts in, and the blonde experiences what it means to be made ‘airtight’ for the first time in her life.
It’s a beautiful moment all around. Everything that MJ could have hoped for in fact. Not only has she successfully gotten her Master and Gwen together, but the blonde has even named Peter as HER Master as well. There is that one last thing getting in the way though. Gwen isn’t from this world. She can’t stay here all the time, or it’ll destabilize things. There’s only one thing for them to do, really… whenever Gwen can’t be here with her slave-sister and their Master, she needs to have something back in her world for her to remember them by.
With her mouth full of tentacle, MJ can’t exactly suggest what she wants to suggest to Peter verbally. But she can lift her legs and wrap them loosely around her Master’s hips, tapping her heels against his back to give him an idea of what she’s ‘suggesting’. She knows he catches on after a while because he pauses for a moment… before fucking Gwen even harder.
The blonde loves every last second of it… just as much as she loves when their Master finally slams into her one last time and begins to cum. He cums and cums, filling Gwen to the brim and then some with his seed. He’s breeding her, just like he’s already bred MJ. It’s not like they’re keeping it a secret necessarily, but they haven’t announced it quite yet, mostly because MJ is only a couple months along. Still, it does the red head’s heart good to know she’ll soon be joined by her slave sister in another way. Together, they will bear their Master’s children. What’s not to love about that?
As he slowly pulls out of Gwen, their Master watches them cuddle for a moment before extracting his tentacles. Then, he slowly and carefully takes Gwen out of MJ’s arms and sets her aside. He’s not quite so careful when he roughly pulls Mary Jane up and flips her over onto her hands and knees. Not that she would want him to be. She’s been a bad, bad girl… and she’s VERY happy to be taught a lesson and punished most severely for daring to overstep~
Her Master knows exactly what sort of… discipline she needs. MJ is just along for the ride.
