Huh, Hypnotica's powers don't work on you

Hypnotica strokes her cock and approaches you and Titgirl, her spiral eyes shining bright. You're still positioned behind Titgirl, who is on all fours with her tits touching the ground. She whimpers, struggling to resist Hypnotica's power, whatever it is, but at the same time you can tell her pussy is just as wet as before.

"You two are having fun." Hypnotica says. A statement, not a question. No... a command.

"Yes, we are." Titgirl moans loudly and starts pushing herself onto your cock again, fucking herself without you even doing anything.

"H-hey, Titgirl, wait... who is this? What's happening?" You try to ask. Titgirl turns back to look at you and smiles, her eyes replaced with spirals like Hypnotica's.

"We're having fun." She says with a vague smile. Clearly it's some kind of hypnotizing power... but you feel like you're still in control. Then again, seeing Titgirl brainwashed, impaling herself on your cock... it's really hot.

"You will service me while you fuck yourself stupid on... whoever this is. Give me the best blowjob of your life." Hypnotica commands, standing in front of Titgirl and positioning her cock in front of the hero's mouth.

"Uhhh huh. Fuck stupid. Fuck me stupid!" She yells, bouncing harder and harder. Unable to resist, you grab on to her ass and start thrusting. Titgirl then crawls forward slightly and takes Hypnotica's cock deep into her throat, sucking and gagging as drool runs down her lips and onto her enormous swaying tits. She looks like a proper fuck-cow.

"And you, tell me who you are. You have a dick but you're shamefully flat. You're not from Futanaria." Hypnotica says to you, though you don't feel ****** to answer. Her power isn't working!

"I'm... from somewhere else. Another world. I guess Titgirl thought that was hot?" You shrug and continue fucking the superhero, who is just mindlessly taking it while worshipping the villain's cock.

"Well, get out of here. Titgirl is my prey." Hypnotica hisses.

"No can do. This feels too good." You keep fucking Titgirl, ignoring the villain's command.

"WHAT?" She snarls, the two of on either end of Titgirl, spitroasting her, using the hero like an object. If she's conscious in there, you guess that she's having the time of her life, knowing how much she likes being bossed around and used. "Stop fucking her now! She's mine!"

"No." You grin, going harder and deeper into the hero's hole.

"Then I'll make her crush you. Titgirl, I command you to---ungh...oh fuuuck... I forgot how good at this you are..." Hypnotica groans and her knees start to buckle, she puts her hands on Titgirl's head, holding her in place. Titgirl is unable to resist giving the best blowjob of her life, and it was clearly too much for Hypnotica to handle as she cums down the hero's throat. Hypnotica arches her back and lifts her head up, rejoicing in the feeling of cumming in Titigrl's mouth, with her orgasm releasing such an enormous volume of cum that a lot of is is dribbling out of Titgirl's mouth and onto her tits and the roof that the three of you are on. At the same time, you notice her spiral eyes start to return to normal for a second.

"J-j-john!" Titgirl cries out, feeling an orgasm of her own. "C-c-c-cum in me! Fill me up! Make me yours! Make me your slut and not hers!"

You're unable, or unwilling, to ignore Titgirl's request, and you immediately let yourself go, your cock pulsing as you release multiple heavy loads of warm, sticky cum into your new superhero friend. You groan loudly as you do it, Titgirl's pussy squeezing and massaging your cock to get every last drop out of you. You feel your own knees get weak and you release your grip on Titgirl's ass, but the superhero's pussy still holds you up, milking your cock for another moment before releasing you. You fall back onto the roof, spent and happy. You almost don't care to see what happens with Hypnotica, but you prop yourself up on your elbows to watch.

Titgirl is still in her position, your cum running down her leg and Hypnotica's cum running down her lips, but there's something different about her. She seems... more powerful.

"HELEN!" Titgirl shouts. "We broke up! You have to get over me! I can't date someone who is evil!"

"B-b-but Claire! I just..."

"No! When I met John I knew we had a connection... we're both from other worlds, we're both affected by the yellow sun of this planet. My powers and his powers just had to combine for me to be strong enough to resist you!"

Wait, YOU have powers? What is she talking about? What happened to Titgirl when you came inside of her?
