Hope Van Dyne a.k.a. The Wasp knew she was taking a big risk. One she didn't really want to take, even though she had been thinking about it ever since a woman enslaving alien had used magic to construct herself a palace outside of New York.
She wanted to avenge The Avengers, SHIELD and the countless women who had been enslaved, and ideally save them from the debauchery they were going through, but honestly, she had been afraid. She hadn't wanted to deprived the world of superheroes, so she had stolen her father's technology and started fighting crime while remaining tiny and out of sight so she wouldn't get the attention of Sif and her slaves, but it had been no use.
Somehow Sif had found out and sent Natasha Romanoff, a.k.a. The Black Widow, to capture her, perhaps assuming that she would be too proud to run. It was certainly the hardest thing she'd ever done, but Hope managed to do it.
She should have probably run to the other side the world, or find a way to get off world, but it felt there was no way she could truly go to escape Sif, so the only option left to her was trying to infiltrate her base and to land an attack before she was discovered. Luckily for someone who could shrink themselves infiltration was easy, especially as in this case Sif didn't even have any guards, or locked doors. Unfortunately Hope wasn't prepared for what she found in that palace.
Of course she had seen plenty of footage on her TV, and had even used the website one of Sif's slaves had set up to scope out the place, and prepare herself for what she may find there, but seeing it on screen and witnessing it first hand was completely different.
Especially as her heart was racing from the risk she was taking, and Sif's magic had to be affecting her already, as she found herself staring at all the writhing body she found. Like the woman who had almost captured her, The Black Widow, getting her big juicy ass eaten by her girlfriend Maria Hill. And Jane Foster and her assistant in a 69. And the aliens strap-on fucking two former Agents of SHIELD, while they licked the pussies of two other Agents.
Most of all though Hope found herself watching Wanda Maximoff, a.k.a. The Scarlet Witch, bouncing up and down Sif's lap. After a few long minutes of just staring Hope moved in for a closer look, and sure enough her initial thought/fear had been right, the little Witch wasn't simply riding the alien with her pussy, but with her ass hole.
Maybe the most powerful human alive was eagerly impaling her most private hole on Sif's dick, which Hope had always found ridiculously hot, even when she had been watching on that website. And she didn't even like women. Did she? She had been telling herself she didn't over and over again ever since Sif showed up, but she'd never been sure, and right now she was unsure as she watched a woman anally ride a dildo to orgasm.
"Oh Mistress Sif, please can I cum." Wanda whimpered, "Please can I cum on your big cock like the dirty little anal whore I am! Please? Oooooooh please, I need it, I need it sooooooo bad! Fuck me! Mmmmmm, fuck my ass hard and deep and make me cum. Please Mistress, ohhhhhhhh, ass fuck me, oh God! Oh Mistress! Ooooooooohhhhhhhhh fuckkkkkkkkkkkk!"
"You may cum." Sif interrupted her slave's rambling, "Cum now, on my big cock, you beautiful little slut. Yes, that's it. Good girl. Mmmmm, good little slave of Sif."
As soon as she had permission Wanda started frantically hammering herself up and down her Mistress's dick, almost instantly having the hardest orgasm Hope had ever seen in person. The way she screamed, shook and squirted all over Sif's stomach was truly out of this world.
Of course it was nothing Hope hadn't seen, or touched herself too, on the website, but again to see it in person was something else, and weirdly made her feel jealous of the girl so totally humiliating herself in that moment. Especially when Sif effortlessly stood up and started bouncing Wanda up and down on her lap as if she was weightless, practically using another woman's most private hole to masturbate the dildo strapped around her waist.
Surely it was impossible, but as she did that Sif seemed to look directly at Hope. The most likely explanation was she was just looking into the distance and concentrating on not cumming so she could continue butt fucking her sex slave, as Hope was way too tiny for her to notice at that point. But if Sif could see her, then Hope was screwed. Literally.
Her plan rested on the element of surprise, and a combination of her own curiosity and Sif being more powerful than she thought had perhaps ruined that. Her only real chance now was to do something while Sif was distracted, but the second she started advancing the taller brunette smirked, as if daring her to do something about it, which froze Hope to the spot.
For a few long seconds Hope was frozen in fear, and admittedly lust, as she watched Wanda's butt being brutalised, then suddenly Sif let go of her precious Witch and let the exhausted woman fall to the floor.
Wanda cried out with pain as she landed on her sore ass, but she barely hesitated before lifting herself up onto her knees and wrapping her lips around the dildo which had just pummelled the deepest part of her bowels. Wanda then moaned shamelessly as she tasted her own ass, and then began eagerly cleaning it, and again Hope couldn't take her eyes off this obscene sight. Just as Sif couldn't seem to take her eyes off of the tiny superhero.
"Well..." Sif purred, "Aren't you going to introduce yourself?"
Again Hope froze, before looking behind her in the vague hope there was someone behind her, but nope. Sif was referring to her. Sif knew she was there, and now she was truly screwed. And about to get screwed. Luckily for her Hope had managed to come up with a back-up plan in case she was caught, which was now surely her only option. But could she really go through with it?
Especially now she actually wanted to do it? Well, she wouldn't have thought of it in the first place if some part of her hadn't wanted to do it, but still, it was quite the adjustment to her original plan. But since she had no other option she returned herself to full-size, and then got down on her knees in front of the terrifying woman.
"My, my name is Hope Van Dyne..." Hope introduced herself nervously.
"Huh... do you have a superhero name?" Sif asked out of curiosity with a raised eyebrow.
"She's, she's The Wasp." Wanda weakly informed her, pausing the blow job momentarily.
