Accept the anxiety pills

Gwen returns with a glass of water and places two tiny pills in your hand. They were barely even the size of a pea, and your sister seemed to agree. "I wasn't sure how many are needed, so just to be on the safe side, you should take both. Mom used to take only one, but she also didn't wake up screaming in the middle of the night. If you're curious, they work by blocking your serotonin recept-.... uh," she trails off upon noticing your lack of interest. "They dull your emotions, basically."

"I see." You swallow both and wash them down with water, hoping that it will be the solution to your problems. You managed to get by for an entire day even without meds, so all things considered, you had reason to be proud. Most people probably would've gone insane... "So how long does it take until they work?"

"Dunno. I guess you will notice. I'll be at home with you all day anyway, so if it's side-effects you are worried about, chill. I gotcha covered." Hearing her say that was reassuring, at least one person you could rely on.

Since the two of you had nothing else to do, Gwen went downstairs to prepare breakfast for the family while you remained inside her bedroom to play some games on the computer. Before long, you already feel... bored of it, though. Which was strange. You loved gaming. Well, used to anyway... you barely even notice how everything around you felt less exciting. Dull. It's like all color was fading from the world, but... it felt soothing. Relaxing. Is that the effect of the pills... ? You didn't care enough to think about it, and instead embrace the cloudy fog that looms over your emotions and keeps them neatly tugged away where they can't bother you anymore.

A short while later, nature calls, and you get off the computer to walk towards the bathroom. It's in the hallway where you stumble into your father, who gives you a confused stare. While it didn't register to you what he's looking at with such big eyes, he was enjoying the view of a barely legal teen girl who walked around completely nude and without a trace of shame. Not only that, but she was also showing off the tiniest, most perfect pussy between her legs without a single hair in sight, and with the playful scent of coconut all around her young cunt.

"Wow," he exclaimed with slightly raised eyebrows while enjoying the view. "I wouldn't mind a piece of that," he remarked with some wit, fully aware that a girl of your age wouldn't give in to such advances.

However, you merely shrug in response. "I guess," is pretty much all you can be bothered to say back to him before moving on to enter the bathroom. He's left rather stunned, while you close the door and use the opportunity to relief your bladder.

On your way back, you find Gwen back in her room scurrying around in panic until she turns around to find you, safe and sound. "Jesus, John. Don't just disappear like that!" You shrug. "What's up? Cat got your tongue?!" She seemed full of adrenaline. She probably assumed you had jumped out the window or something...

"Nah." You simply get back to the computer and mindlessly browse the web.

"Gee. I guess two pills were too much after all... come on, get up. Food's getting cold downstairs," she points out while helping you to get back out of the chair. She's even got the presence of mind to dress you with a fresh pair of boy-shorts and a bra. Sweet and caring as she is, she also guides you downstairs to ensure you've got no chance to get lost on the way now that you were a bit more... absent-minded. Your father could barely take his eyes off you, but he was careful enough not to stare unless Gwen was occupied.

Upon finishing the meal, you returned upstairs with your dad following closely while Gwen stayed behind to wash the dishes.

In the meantime...

Gwen gathered the different plates and brought them to the sink. She had always been a stickler for cleanliness, the only one in the family to obsess over it. One plate after another, she dutifully scrubbed clean until they were shiny and acceptable! With a separate towel, she wiped them dry and briefly admired her work. It was only then that she realized that she hadn't guided her brother back into her bedroom, lord knows what happened to him this time.

She put the kitchen towel away and peered into the living room first - nope, nobody in sight. Upon walking up the stairs, she checked John's bedroom first. Again a blank. The bathroom was equally empty, but to her surprise, she spotted the boy-shorts and the bra on the ground. Did he walk around naked again? She finally entered her own bedroom while shaking her head. "John, you can't jus-" Utterly confused, she looked around her room without seeing anyone? Where the hell did he go?

Suddenly there's the sound of her dad's deep chuckling from the nearby master bedroom, and she quickly approaches it on silent feet. She almost stumbles before arriving. The door was open just barely enough to reveal a small gap that she could look through. There on the large bed, was John - or rather Sara? Completely nude, and with their dad sitting by her side. Upon changing her position slightly, Gwen got a better idea of where Joh- no, Sara's tiny hand was at. It was planted right on top of their father's naked cock. Gross!! After the initial shock wore off, she noticed that he wasn't wearing anything anymore either! His hairy body was in full view. Luckily 'Sara' was lightly sedated, or she would either get a panic attack unlike anything seen before, or just run down the street while screaming...

Instead, the pubescent girl did just as she was being instructed, and began to mindlessly slide her hand up and down the surface of their dad's erection. On every downward stroke, the foreskin slid down enough to reveal a massively bloated, purple mushroom tip. It looked grotesque, a huge fleshy crown attached to his veiny and immensely thick shaft, and a growth of pubes surrounding the base. At least it looked like he was fine with just a handjob. It was probably the first time he ever even got to be in the same room as a girl as young as that. No doubt he was happy already to get as far as this.

It was unexpected to see him soon grabbing a fistful of Sara's fine hair, and using it to guide the girl's mouth down to his crotch.

Gwen's pulse began beating faster. Should she put a stop to it? What would her excuse be? By all means, their dad assumed that Sara was doing it completely willingly. What's the female equivalent of a cockblock? Getting clam jammed? No that would be too difficult to explain.

At the same time, Gwen watched her sibling opening the mouth to engulf that monstrous cockhead with a soft pair of lips. Their father released a pleased moan, and hearing that was enough to make Gwen's cheeks blush. It wasn't even something she anticipated, but it was... kind of sexy? Her hand automatically reached down into her panties, and before she knew it, she began stroking her small appendage with great care while quietly listening on.

Sara's head moved up and down at a slow, deliberate pace, coating the massive slab of meat in a thick layer of saliva and making it glisten lewdly. Dad simply leaned back against a pillow, while using the fistful of hair to continue guiding his submissive servant. Even an unskilled girl can give an amazon blowjob as long as she's hot enough, by the looks of it anyway...

Their father leaned to the side and whispered something into Sara's ear, but before Gwen could figure out what it was, she could hear the faint noise of keys downstairs before the door began unlocking and opening already! She quickly tugged her girl-cock back into the constraining panties before - as silently as possible - rushing down the stairs to greet... "Mom?!"

"Hello dear, I'm sorry for being late," came the mature woman's response as she entered the house and dropped her bags and purse. "How have you been? I see you took good care of the house! And it smells nicely," she added upon inhaling more deeply - the exotic scent of coconut. "Where is everyone?"

Gwen began blushing even more. If mom finds out that her husband is being unfaithful, it would cause even more problems, on top of the already existing ones! "Uh. They are, you know... it's kind of tough to explain ya know? They are busy in the... garden? They-"

"It's fine, spare me the details. I can't stay long anyway, I mostly wanted to get rid of the bags." She gave her daughter a quick peck on the cheek. "I'll need another day at work to help clean up a mess someone made. Tell everyone I said hello." Just like that, she turned and left again.

Phew! Catastrophe barely averted.

But...
