Yuugi would be the first to tell anyone who asked her life had improved dramatically since she'd taken 6O in. She wasn't just talking about the sex, either (though that WAS a contributing factor). The Former Hells could be a dark, lonely place, and someone like 6O was a ray of life and sunshine that made it so much more pleasant. At first it had been an arrangement of convenience, sex for housing and protection. But despite being enough of a wanderer for her soul to end up here, 6O was so pleasant to be around Yuugi was now consciously making suse she made her lover's life comfortable enough to be worth spending it together.
All together, it was more than enough that Yuugi was willing to take on another guest. Especially one with a connection to 6O. The gynoid had been exploring when she'd found the wondering spirit of 21O, another android she'd known in a past life. Considering how lonely this place was, and understanding by now how androids needed company (even if 21O had a different personality), Yuugi had agreed to take her in. There was just one complication.
Sex. Yuugi had barely controlled herself around 6O and got caught within days. Ever since she'd resumed her habit of casually tugging her cock whenever she felt like it, along with frequently fucking just for fun. 6O had warned Yuugi that 21O might not be so... unconditionally receptive, and asked her to try and control herself, at least long enough for her friend to be more comfortable. It was an insane request to make of an Oni... but it was 6O, so she'd agreed. Sure about half her frequent "bathroom breaks" were an excuse to quickly whack off in private, and having to wait for a chance to slip away for sex with 6O meant she was usually a hair trigger when they did. It wasn't quite enough, of course, and she was slowly feeling pent-up and 6O had to set a limit on their sessions before they started. But she gave her word, and kept it.
And 6O noticed, so when she thought they had a little while too themselves, she gave Yuugi permission to go a little wild. Anything she wanted, as selfish as she wanted, to get some of the energy out of her system. And Yuugi had almost torn her bloomers off, stroking herself just a few times to blow the inevitable hair-trigger load before she got to the fun part - telling 6O to kneel down, then shoving her cock in the gynoid's mouth, grabbing her head in both hands, and going wild.
"Nnnnnh, fuck! Holy shit, I need this...!"
And that's what she was doing right now, thrusting her hips and rapidly moving 6O's head up and down her cock, as callously as if she was using a sex toy. Yet the warm sparkle in 6O's eyes, even as they filled with tears from the strain, just made this better than ever. She was so caught up in remorselessly fucking her girlfriend's face she wasn't paying any attention to little things like the door opening...
