She lay there perfectly still for a long while, feeling her racing heartbeat against her fathers which steadily slowed with each passing breath. After what seemed like an hour, a muffled snore erupted from her father’s mouth and Sarah breathed a sigh of relief. She was dripping with sweat from the stress, but her pussy was even more wet. The entire time she had lain there, her father’s cock was filling her entirely, throbbing slowly, teasing her to the edge despite the fear. She barely dared to move as she knew that if she slid off his cock now, she would surely orgasm and collapse on top of him. And if that happened, he wasn’t going to sleep through that.

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.

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.
