No; time to run

"...Maybe I'll just, just use your... Um..." Your father glances between your legs. "I'll just have one more go. We can always collect the medicine after." With that, he grabs you by the waist and pulls your prone body closer to the edge of the desk. "One more time won't hurt..."

Judging by the look in his eyes, he's dead-set on punishing your sore body again and wasting another precious dose. You need to interrupt him, somehow... Maybe if he stops fucking you for five seconds, then he'll come to his senses, realize how unacceptably he's treating his only daughter, and maybe put that Zanalfil to better use.

Unfortunately, your wrists are still tied to the desk by a pair of USB cables... But your father's been manhandling and pounding your body for a while now, and the makeshift restraints are getting pretty loose. You wiggle your arms a bit, and soon they're barely hanging on.

When your father's hand leaves your waist to line up his cock, you take the opportunity to roll off the desk and out of his reach. Before he can react, you spring to your feet and make a run for the door.

"P-Pumpkin! Wait!" He gives chase immediately, stomping around the desk. Luckily for you, he has to navigate around an office chair and a pool of jizz, nearly slipping in the process; that gives you enough time to escape the room. "Come back! I... I've got more medicine ready, and--and you're still covered in it!"

Without looking back, you sprint through the hall and down the stairs. He's still shouting, and you're leaving a sticky trail, but right now all you care about is putting distance between you and your temporarily-even-more-sex-crazed father.

As you careen into the living room, though, a peculiar sight stops you dead. Your brother Pete is sprawled on the couch, his legs spread wide. Kneeling before him is your mother, bobbing her head and hollowing her cheeks as she sucks him off like a pro. Capping off the scene is the hardcore porn movie playing on the TV. The sound is muted, but you know a teen gangbang when you see one.

“Little faster, Mom... I’ve got places to be.” He pauses as she shoots him a glare. “Uh, please suck it faster. Thanks.”

Growling with frustration, she releases his member just long enough to snap at him: “Don’t look at me, or talk to me, or... Just... Focus on the film. One more dose.”

“Okay, okay—Huh?” Finally noticing you in the corner of his eye, Pete bolts upright and scrambles for the remote. "I--I thought you guys were busy upstairs--" Then he takes a better look at you, jaw dropping as he oggles your naked, cum-glazed form. "...Holy shit."

“Guh?” Your mother sits up, letting Pete's glistening cock slide out of her throat. “Oh my God! Sarah, what did you do?”

Just then your father comes flying into you from behind, knocking you to the floor. You groan, blink a few times, then look up. He’s standing over you with a startled expression on his face, his unnaturally-hard cock bouncing and twitching with every breath.

Everyone stays silent for a moment, until your mother wipes her mouth and speaks in a surprisingly calm tone:

“What the hell is going on?”
