Ethan never treated her like any other step-sister would be treated by a typical step-brother. It’s been nothing but trouble for the two ever since their parents got married a few months ago and jetted off on their honeymoon.
He and Riley were old enough to move out, but ended up staying under the same roof for a few months.
She hardly put any clothes on and this triggered dirty thoughts around the people that she hung out with. Little did she know that her own step-brother jerked off thinking about her tight buttocks and petite breasts. Everything about her was innocent and endearing, from her pale smooth skin, to her sandy blonde hair, to her pink coral lips, to the way her nipples peeked out from beneath her clothing as she knelt before him. He was watching and observing her every move, which now traced every curve of her body in his dirty mind.
He was powerless to stop thinking that way, and what happened next would force them to reevaluate their current status as step-siblings.
One night, as Ethan walked to his room, he stopped at the scenario that played inside Riley’s room. He saw her, naked, humping the teddy. His mouth dropped open when he saw his own picture he had recently posted on Instagram being pasted on the stuffed animal’s face. Did she feel the same way about him? On one hand, this worried him, but on the other, it thrilled him. As she fucked the stuffed animal, her little legs pushed the covers and her small, round breasts jiggled up and down. Ethan felt his cock harden inside his shorts. He whipped them out and began jerking off to his step-sister humping. When the two exchanged glances, they continued masturbating without breaking eye contact. This induced more pleasure and just a few seconds later, cum emerged from their privates, soaking the soft toy and her sister’s shorts that had been laying near the door, where he stood.
In spite of the horror in their expressions, they secretly found pleasure in facing reality. To each other, it was an irresistible pleasure.
Ever since that night, they got naked whenever they wanted and masturbated together. He would sit across the couch with his undressed body and jerk off to her naked, sitting opposite to him with a vibrator that triggered an eye-rolling orgasm. In the shower, he would quietly watch the water rolling from her hard nipples. Riley would sometimes make him pancakes while only wearing an apron and he would get hard and played with his cock right in front of her, watching as she poured chocolate syrup all over her genitalia and sponged them clean using the pancakes he would later eat. She would go on as far as making herself wet on his t-shirts while he watched.
They tried to resist each other because of the relationship, so masturbating felt more right than sex. The text messages shared between them every night highlighted an explicit and pleasurable sexting of ideas on masturbating.
One morning, as Ethan went down for breakfast, he saw her naked and covered with bits of whipped cream on her nipples and on the clean shaved vulva.
He gave in to his lust and reached for her delicious boobs, licking the whipped cream off of them until there was nothing left. Whereas all she did was whine and breathe heavily, making him work even harder.
His hands were more dexterous than his mouth, and he traced her entire body as he had mentally traveled it all over. He grabbed her waist and yanked her close to his newly erect cock. He knelt down, staring at her the whole time, until the sugary vaginal heat mixed with his exhaled cool minty breath.
Instinctively, he reached for her legs and lifted them over his shoulder, eyeing the pool of juice that was dripping from her. This caused it to run down her blossoming butt hole, arousing her further. When his tongue squirmed and hissed on her clitoris, she tried retreating but accepted defeat as he pinned her down even more. Riley rolled her eyes back and moaningly wedged her back as he French kissed her genitalia. For a long time, she squealed and begged him to stop, but he continued to slurp up her fluid.
He felt her rising wave of orgasm as he pushed his fingers into her, in an upward motion, in search of her g-spot. When he discovered it, he gratified her further by thinking about what a slut she was for him.
So, he asked as he slid inside her, groaning appreciatively at her tight pussy, “You want this, right?” They both shook the table, sending the fruit bowl and the utensils flying that had the nerve to get in the way of how far her hands reached out with glee.
She felt her legs go numb as he repeatedly thrusted while she screamed in defeat at his triumph. The rising heat at the top of his penis was a sure sign that orgasm and cum were about to surge out of him and into her. To indicate that she is on a contraceptive implant, Riley tapped her upper arm with her other hand, and his pace quickened with excitement.
“I’ll let you cum inside me if you like. I won’t tell my/our parents. I promise!“she teased, begging for more.
While she was having an orgasmic climax, a stream of warm white liquid shot out of him and into her. They continued to lie on top of each other, breathing heavily, and he knew he wouldn’t emerge out of her any sooner. They sensed her body oozing filth, adding to the chaos in the kitchen.
Ethan’s face shivering with joy and exhaustion, said, “We should definitely do this again.”
“Yeah… You might want to put your cum inside me to seal the deal?“ She laughed at his statement, implying how she desired more of his big step-brother.
