Over with Powergirl and Sara things do indeed escalate to a face fucking right quickly, with your daughter grabbing the kryptonian woman's head and hammering away into her throat in short order. The gas and that collar also seem to be doing their part to fuel things however as Sara does not grip powergirl very hard. In fact Powergirl actively seems to be working with your hybrid daughter, pulling her head back slamming herself forward, her hands gently holding onto Sara's thighs as the two of them go at it.
Back on your end you decide to be stubborn, because fuck Stella! Just not like, you know, fuck Stella? You refuse to keep choking her, despite the slow progress you had been making on that front, not really trusting that anymore given how Stella's been acting. Stella pouts a little at this, pressing your hands to her throat a little more firmly. "Aw come on. Pretty please?", She asks with a sugary sweet siren like voice. You have to admit, you almost heed her demand there. Her voice was just so alluring and sultry. But no, you resist, and try something else instead. Your legs feel heavy as hell, but you still manage enough strength to haul them up with some modicum of effort, and wrap them around Stella's head. You get a short rush of satisfaction when your calves press on her cheeks, smushing her face and drawing a surprised 'hurk!?' from her lips. Heck she even looks sort of adorable like this... but you don't care that much about that right now. You push down, trying to slam her against the table. Sadly you don't get far on that front either. You force her to arch her back slightly, but that's about it. However she lets go of your hands and pries her legs off your face. You decide to take this opportunity as well though and try slamming your first right above her belly button, trying to wind her. She jumps a little, but otherwise is still barely affected. Now she just holds your legs by the knees and looks down at you in annoyance. "Would you stop being so difficult already? Sheesh!", she huffs, before suddenly returning the favour. She lets go of your legs and punches down, driving a fist into your stomach and forcefully ejecting the wind from your lungs. You gasp loudly, and find your limbs becoming like limp noodles as they fall back to the table.
Before anything else happens though an intercom clicks on, and out comes the voice of Clark's nemesis. "Stella, enough of your games. Why antagonize that upstart? We have real Kryptonian's to work with anyway. Not that we have time for that anyway. Your 'projects' are causing problem's on the lower levels. Deal with it please. It's hard enough getting personnel here discreetly without them dying all the time.", You hear Lex Luthor's voice say. Stella pauses, thinking while continuing to give that annoyed stare. Before huffing and hopping off you. "Such a needy boy. Ah well. We'll pick this up another time 'Psion'~", Stella says before laughing a classic evil laugh. "Sara, come. We have spawn to placate.", Stella says as she begins to stroll toward an exit behind you. Sara, pauses a moment, thinking, before pushing Powergirl off of her and striding off behind her mother. "Hey, wait!~ Where are you going?~", The blonde Kryptonian woman whines as your daughter walks away.
Right before the two exit though, Stella calls back with a laugh. "Have fun you two! I'd hate for all this gas to go to waste~", she trills before laughing again. A second later the a heavy door slams shut behind them, leaving both you and Powergirl in your cell, now unbound, undressed, and the two of you incredibly horny.
