It was a Friday afternoon, and Sarah and Alex found themselves so horny and turned on after watching a sex scene in a movie that they ended up watching each other as they pleasured themselves while sitting on the living room sofas across from each other.

Unfortunately, just before they were going to explode, their parents arrived home from work.  Alex was on one sofa, hiding his rock-hard cock, while Sarah was on the other sofa, hiding the large wet spot on her shorts.  Both breathing heavily and suddenly watching TV, having no clue where the movie was.

The parents' conversation filled the room, including asking Sarah and Alex how their day at school went.  No real extensive conversation with the kids happened after that.  Both parents were doctors at the local Veterinary Clinic, so they often discussed work issues and patient procedures at home, collaborating.  Both kids were used to this and had perfected the skill of tuning out their parents and the often ‘shop talk’ that happened.

Alex quietly left the living room to take a shower, and Sarah left to change her panties and shorts.  Both were extremely disappointed that they were interrupted and still tremendously horny.

But being deprived of their climax while also being robbed of watching their stepsibling explode only fueled their desire to complete what went undone.  During dinner, Sarah and Alex exchanged glances with each other, a smile here, a gentle touch of their feet rubbing against the other under the table.  Unspoken words and simple gestures kept their desire just as intensified as it was before.

Their parents were great, fully trusted Sarah and Alex, and loved them both, but sometimes were clueless about picking up on subtle, nonverbal cues from their kids.  When Sarah and Alex both volunteered to clean up from dinner and load the dishwasher, their parents simply thought they wanted to watch “Pirates of the Caribbean,” which was the agreed-upon movie for that night.  Friday evening was always family movie night, a family tradition for some time.

It didn’t take long after the movie started for Sarah and Alex to start texting each other.

S: “did u jo in the shower”

A: “No wanted 2”

S: “want to see your cock explode so bad”

A: “saving a huge load for you”

Texting continued off and on throughout the movie.  Both were sharing private pics of themselves with each other and texting horny thoughts that they had never shared before.  Alex was hiding his hard-on from his parents while Sarah was hiding her wetness and excitement.

It was the longest 2 ½ hour movie that they had ever seen, or it just seemed to be.  By the time the credits started to roll across the screen, Sarah was the first to tell her parents that she was tired and was going to bed.  Shortly after, Alex followed with the same excuse.

Both ended up lying in bed, both naked, which wasn’t unusual during the warm and muggy early summer nights.  Finally, they both heard the TV in the family room go silent, which was a clear sign that both parents were going to bed.

Each of them was consumed by thoughts about all that had happened between them since Sunday evening, when Sarah watched Alex through his partially opened bedroom door masturbating to porn and calling out her name.  The teasing and playing games with each other had gone way beyond what either of them had ever planned on or imagined.

The house was still. Sarah was lightly rubbing herself, eyes closed, with soft moans escaping her lips.  Her eyes opened wide, and her heart skipped a beat as she heard her bedroom door creak as it was slowly being opened. To her surprise and delight, it was Alex, totally and completely naked with a raging hard-on.

Her bedside lamp was still on, so she was able to see his toned and muscled body, handsome good looks, but best of all, his 7” cock pointing directly at her.  She instinctively spread her legs.  Their eyes met as they watched each other.

Sarah resumed rubbing her clit, allowing her moans to get louder.  Alex wrapped his hand around his thick cock and stroked it.  No words were exchanged.  None were needed.  They each put on a show for the other.

Sarah was watching her stepbrother stroking his cock hard.  His balls hanging low, swinging back and forth.  His moans and the intense expression on his face as he watched her.

Alex had a great view of his stepsister’s spread legs.  Her bald pussy fully on display.  Her bouncing tits, hard nipples, and her frantically rubbing her swollen clit.

Alex stepped forward into Sarah’s bedroom, so he was next to the foot of her bed. Though his breathing was heavy, he simply said, “cum for me now”.

That’s all Sarah needed to hear.  Her body tensed as she felt an orgasm rip through her like never before.  When her breathing returned to normal, her eyes opened, and she was able to focus; she was limp and exhausted.  Her sheets were soaked, but so was her stomach, chest, and cheek.

Alex was standing next to her bed, smiling.  “That was the biggest load I’ve ever shot.  Sorry for the mess.”

Sarah didn’t care.  She simply smiled back.

Alex leaned over and gently inserted two fingers into Sarah’s dripping wet and moist pussy.  Sarah arched her back as his fingers penetrated her sensitive opening.  She clasped his wrist, but she didn’t need to.  He was already withdrawing two soaking wet fingers.

His voice was firm and spoke with confidence: “Open wide and lick.”  Alex placed his fingers in Sarah’s mouth, and she, without hesitation, liked his fingers, tasting her sweet juices.  Withdrawing his hand, Alex bent over and deep kissed her, their tongues dancing, tasting the deliciousness.

With a smirk, Alex started to straighten up and back away from Sarah’s bed when she clutched his wrist.  Alex was amused but didn’t fight it. He stopped and simply looked into her eyes.

All Sarah said was, "What's good for the goose is good for the gander," as she scooped up some of his cum from her chest.

He took her hand and licked his cum from her extended fingers and leaned down again for another wet, sharing kiss.

Before straightening back up, Alex whispered in Sarah’s ear, “Mom and Dad will be at the Vet Clinic all day tomorrow.  Be ready because I’m going to fuck you hard.  No more of us watching each other get ourselves off."

Without saying another word, Alex swiftly left, closing Sarah’s bedroom door behind him.
