That previous single thought of her own indecency was wiped out by the tidal wave of her curiosity. About the only thing that she was still aware of was her father’s steady breathing and making sure not to wake him. Taking care not to cause too much disturbance on the mattress, she gently shifted further down the bed. Her dad was still unfolded like starfish, so her legs had to slide out alongside them as she brought her face down to the level of his pelvis.

“And do you know the best part?” she asked, reaching down to slowly stroke my dick again, giving me another, slower lick. “The best part is, all you ever had to do was ask! I had such an enormous crush on you, back in high school! I'd have sucked you off gladly, any time you wanted! I'd have done so much more than that... I'd have done my makeup, and dressed up like a girl for you! I wasn't very good at it, yet, but I'd have done it for you, if you'd wanted me to. I'd even have given you my cherry, let you be the first one to fuck me in my ass—anything you wanted, I'd have done it, if only you'd asked! But you never did that, never gave me the choice. You and your friends decided to force me, instead. So now, you don't get a choice! You get that, Brianna? You belong to me, now, just how I used to belong to you! So, I'm going to go upstairs now; it wouldn't be safe for me to let you drive yet anyways, not until the drugs I gave you work their way fully out of your system. I'm going upstairs, and you can just stay down here and think about it. Think about how this is all happening to you just because you never had the courage and courtesy to ask! I'll be back in maybe an hour or so, once I'm ready to go again!” She paused, staring deeply into my eyes, then suddenly kissed me, deep and passionate, full on the lips! I was still trying to recover from my shock as she was walking out the door, closing it behind her.

idk if you've played chaos;head (or watched it, I never saw it so idk if it's in the anime) but it's set in the same world as steins;gate (which I've watched but never played) and things the eyes see but the brain doesn't process are a literal plot point, you could almost certainly make a fairly lore accurate manip with that if you like this world.
