A younger brother and older sister love each other to a surprising level, to both of their surprises.


Jackson Kent was in his room doing some dumbbell exercises. Ever since his father died, he felt like he had to toughen himself up. He was always a nice tiger and stuff, but...he just felt like he needed to do this. Their neighborhood wasn't the best, and with their father dead and their mother someone they never knew, he had to live with his 18 year old sister. She was wonderful and certainly a hard worker and optimistic in his eyes, the last family member left and one he really cared about. He felt like he almost needed to toughen himself up to make sure he could protect her. It almost sounded silly, a kid trying to protect an adult sibling. At the very least it gave him something else to do to keep his mind off of stuff. Plus it was healthy, not a bad thing to pursue. Despite being 14 he was now very physically fit. Taking a martial arts class helped him learn how to fight.

"Jackson?" asked his sister as she peered in, "Wanna have a pizza for dinner?" She smiled at him. She really cared for Jackson just as much as he cared for her. She was happy he was healthy and well, especially since he's her only brother. She felt like she needed to make sure he was happy in the unfortunate world they ended up in.

"Sure April," Jackson smiled as he set his weights down, "We could watch a movie too. I got that mystery you wanted to see from the library." April was touched he remembered small things like that. She only mentioned that passingly like three days ago.

"You're sweet Jackson," she warmly smiled, "Sounds like an evening. I'll just need to go take out some trash real quick, ok?"

"Sounds good!" Jackson acknowledged before April closed the door and left. Jackson admittedly cared for his sister almost too much he felt. Ever since their father died, people at his school felt he got too serious and weird so they avoided him. He didn't mean to come off that way and it did make him upset that people can't overlook it, but his sister cared.

They ate their pizza and watched the movie once she got back. They enjoyed it and afterwards separated to their rooms for the night. April wished him good night and gave him a hug with a caring kiss on the forehead. Jackson worked on some homework then went to bed a bit early. He then fell asleep and eventually the blackness of sleep gave way to a dream. He moved around hazingly in what appeared to be his sister's room.

"What am I doing here?" his dream-self asked.

"Jack?" called a familiar voice. Jackson raised an eyebrow. It was definitely his sister but she sounded...weird, "Are you ready Jackson?~" Jackson had no idea what was going to happen. Suddenly before he could answer, his sister walked in without any clothes. Jackson's eyes widened and he blushed in shock, and with a blink of an eye he was suddenly on his sister's bed laying, with her in front of him.

"Oh Jackson you're so good to me~" April said as she caressed his cock. Jackson moaned, almost wanting to resist this taboo but the dream wouldn't let him. He admittedly...almost wanted it to continue just as much as he wanted it to stop. Right as his sister's lips and tongue were a millimeter away from his hard member, he suddenly woke up. He panted, still in shock from the dream. The details seemed so real to him. He saw the clock and it said 3 AM. Dreams were weird with timing. He then laid back to think what had happened.

"Do I really find...my SISTER hot?" he asked, "I mean I lover her...and...she loves me..." This definitely confirmed he cared for his sister too much if he was now starting to physically and romantically love her. He remembered the image of his nude sister in his head and began to quietly fap. Then he stopped, almost feeling ashamed. But his feelings fought the shame. He shook them off and then got out of bed to grab a glass of water to take his mind off of it. He walked past his sister's bedroom, whose door was cracked open, and noises were emitting out.

"Oh Jack~" April quietly moaned in her sleep. Jackson blushed a deep red, partly from the shock of her having a similar dream and partly from her seductive voice sounding just like from the dream he had. He then saw his sister purr in her sleep and move her fingers to slightly stroke between her legs. Jackson blushed even redder and quietly but quickly went back to his room, choosing to forget the whole glass of water thing. He tried to go back to sleep.

April soon after woke up, eyes widened. Just like her brother, she began to wonder why she was having such lewd taboo thoughts. She similarly reached the same conclusions: perhaps she cared for her brother so much that the lines between familial love and romantic love were blurring. She certainly had no other man in her life, definitely none as caring as Jackson. She admitted to herself in her thoughts that seeing her brother naked with those strong muscles was enticing. She began to finger herself, and unlike Jackson she didn't stop herself. She blushed and tried not to moan out loud. Once she was satisfied she went back to sleep.

The next morning was awkward for both of them at breakfast. She was wearing the robe she always wore in the morning but now Jackson couldn't see it as anything other than bringing out his sister's attractiveness. Similarly, April was used to seeing her brother wearing a tank top in the morning but now it just highlighted his physique. After finishing her cereal, April decided to leave to try and avoid her feelings.

"I'm gonna grab the mail real quick then work on some stuff in my room, ok?"

"Sure," Jackson nodded as she walked out. Damn now her ass was attractive too. Once she was out of eyesight and earshot he took a deep breath and rested his hands on his temples and tried to think. But that was cut off with a cry from her sister.

"LET ME GO!"

Outside, a random and clearly drunk bulldog was chuckling as he had her arm.

"It's ok, miss," he insisted, "I just want to invite you to my place. You'd be a perfect fun time and you'll love what I have packed away~"

"Fuck off creep!" she growled before punching him. He took the punch like it was nothing and growled himself.

"Well," he snarled, "I asked nicely and this is how you repay me?" He raised his fist and April was paralyzed with fear. Suddenly Jackson rushed out and punched the assaulter in the jaw so hard he spit out a tooth. He then punched him in the gut for good measure.

"You leave my sister alone," he roared. April blushed at seeing Jackson defend her.

"You sure I should kittyboy?" the Bulldog chuckled, "If I leave her alone no one else will wanna fuck her ugly face." Upon hearing that Jackson roared again and uppercut the bulldog to knock him out. The assaulter fell onto the street pavement, out cold. Jackson panted and then turned around.

"Are you OK April?" Jackson asked, worried. He held her arm to look at it. Once he saw there was no bruising or other injuries on her, he hugged her warmly.

"Y-yeah Jack I'm fine," she answered. His hugs were so warm, she could tell how much he loved her and was willing to protect her. Damn it she couldn't hide her feelings anymore. Why shouldn't she love someone who loves her so much back? They went inside the house.

"I swear April if that jerk talks with you again, so help me--" suddenly Jackson was cut off my April kissing him on the lips. After what felt like a whole minute to both of them, she finished it and smiled while lovingly staring into her brother's eyes. Jackson blushed, wondering if that seriously happened.

"Oh Jack," she said soothingly, "I love you so much."

"I-I love you too sis," Jack replied, trying not to let out how far that love would go.

"You're always so alone," she said, "Just like me. You understand me, you care for me, I..." she blushed and hesitated before finally going all in, "I want to prove how much I love you Jack." She unbuttoned her robe she was still wearing and let it drop to the floor. Jackson blushed a deep red and in no time a boner stuck out in his shorts.

"S-sis are you sure you wanna do this?" Jackson asked, "C-cause I kind of want to..." April nodded and smiled. Jackson then brought his lips closer to April's as the two stared into each other's eyes once again. Jackson kissed her lips. April pecked his lips back. The two slowly closed their eyes with each kiss and stroked her hands around each other's sides. Finally, April took off her brother's tank top and initiated a french kiss. Jackson returned the favor and began feeling her pussy gently. April moaned softly and lowered Jackson's pants and underwear so she could return the favor. They made their way to her bedroom.

"Here's fine?" she giggled.

"Yeah, it seemed...perfect~" Jackson said as he had her lay down. April didn't care that Jackson was her brother, 4 years younger, or even 12 cm shorter. She wanted to feel love. Jackson moved his head between her legs. "I love you April, you deserve this~" He then licked her pussy passionately. April blushed and caressed his head. Admittedly this was better than her dream.

"Oh J-Jack~" she cried pleasurably, "F-fuck~" Jackson's feline tongue lovingly tasted every crevice inside her it could reach. Once he could begin to taste her juices starting to leak out, he purred and pulled away to adjust himself, his hard cock right outside her pussy. April was impressed. It was average all things considered but he clearly matured down there surprisingly young. "Put in it Jack...please~" she softly begged, biting her lower lip. Jackson blushed and obliged, ending both of their virginities as he fucked them. After a few thrusts he got into a nice motion and they both moaned.

"D-damn this feels so good~" Jackson huffed, starting to really enjoy himself. He felt his sister's breasts, April soon putting her hand on his to encourage it. They were long past any taboos at this point. Jackson lifted one of her legs to hold onto so he could thrust quicker. April's tongue drooped as the pleasure advanced to euphoric bliss. "I-I think I'm close."

"M-me too Jack," she moaned, "FUCK~" Soon they both squirted their cum, Jackson not thinking to pull out. They recovered with a cuddle and then it hit Jackson.

"O-oh shit!" Jackson panicked, "I-I didn't pull out. Shit shit shit. What if you get pregnant? I-I" April kissed him to calm him down.

"If we get a child, I'll be happy to have it~" Jackson blushed and relaxed. The two siblings then hugged and got back to cuddling.
