Luke Claesson, her mischievious younger brother

Tilda was interrupted from her thoughts by the intense pain of an object smashing into her groin. Tilda hadn't noticed her brother playing kick-ups with a soccer ball nearby, and she certainly didn't notice as he lined up the ball in her direction and kicked it as hard as he could. The ball violently slammed into her pussy dead center, triggering the millions upon millions of pain receptors in that tender organ.

"OH!" Tilda exclaimed in a mix of shock and agony. Immediately her body bent forward, and her knees locked together, while her face twisted into an expression of agony. Her hands went down to cover her crotch. "Oooooohhhhhh" she moaned in pain, as she tried to massage the burning agony away.

As Tilda was trying to catch her breath, Luke ran forward to pick up his ball, before running off again. As he ran, turned his head back and called out to her.

"Oops, sorry Sis!" His tone was as insincere as the grin on his face.

“LUKE! You little…owww,” Tilda’s threat was interrupted by a surge of pain from her groin.

Tilda wanted to chase after him for payback, but she knew that he must have run far away already. Luke was a compulsive prankster and an absolute demon, and his pranks often consisted of hurting Tilda’s breasts and groin.

Luke (birthname Loke) was Tilda’s younger brother by three years. He had inherited the Claesson’s standard bright blue eyes and slim build, but his hair was dark brown, curly and unruly.

Luke often took delight in tormenting his sister. He had found out early that if he hurt Tilda’s breasts or pussy, she would be in too much pain to chase after him and take ****. Plus, Luke just found it funny to see the various reactions that Tilda would give when he busted her privates. He loved to make his sister cry out in pain, and the sound of her agonized screams were like music to his ears. To that effect, Luke would always design pranks that would hurt Tilda’s intimate areas. He was able to build elaborate contraptions to carry out his plans and could even spend entire days plotting how to **** his sister’s tender regions.

Tilda remembered one time when he had positioned a tennis ball machine outside her room and triggered it so that it would start firing when the door was opened. Not only that, but he also adjusted the machine so that it was at crotch height, and cranked the speed up to maximum. Tilda exited her room that morning only to be violently assaulted by a tennis ball slamming into her groin with incredible ****. A loud THUD! was produced, followed shortly by an agonized shriek.

“AAAAAAAAAAAAAHHHHHHHHH!”

The pain was intense. The young teen was so overwhelmed by shock and pain that she couldn’t even move her arms to protect her bruised privates. This would be unfortunate as two seconds later a second tennis ball was shot out, followed by a third. Both struck their intended mark exactly, burying themselves in the very center of Tilda’s cameltoe, with the poor girl screaming each time in an increasingly higher pitch.

Her eyes were wet with tears, and her entire body trembled from the burning pain in her pussy. She did not expect such brutal agony the first thing in the morning.

She cupped herself and bent her knees together. By lowering her posture, her groin was out of harm’s way, but her tennis balls were now hitting her lower stomach. Her ovaries and uterus were thoroughly battered as ball after ball slammed into that tender skin just below her navel. A throbbing pain began to build up in her lower stomach, though it couldn’t compare to the hellish burning agony in her crotch.

Tilda eventually sank to her knees with a cry, at which point Luke finally stopped the horrid machine… only to reposition it. He aimed it at her tender breasts and started it again, grinning as the grimace on her face intensified. Tilda’s sleepwear did little to protect her sensitive breasts from the merciless tennis balls that seemed hellbent on crushing her tits into a fine paste via impact ****. Also, since her breasts weren’t secured by a bra, they would jump and fly about as the sporting goods struck them.

Poor Tilda was so preoccupied with the pain in her crotch that she couldn’t even move her hands away to shield her breasts. Furthermore, the shock and pain of the hits was so much that it didn’t even occur to her to move out of the way of the tennis machine’s line of fire. So, Tilda ended up taking around twenty or so tennis balls to her supple breasts before she finally collapsed down onto the floor. With each hit she cried out, tears streaming down her face. As she laid down, she had one hand over her breasts and the other firmly planted between her thighs, and she was taking deep breaths to try and regain some control over the pain that was now emanating from each of her private regions.

Luke had simply stopped the machine, and then proceeded to take some photos of the downed woman. Then, he pushed the machine away, laughing all the while. Tilda had remained there for maybe an hour before she collected the strength to get up and hobble to the kitchen for an ice pack.

Our protagonist shuddered to remember that incident. It was one of his more brutal and elaborate pranks, but he had other ways to **** her. He had often taken his paintball gun and aimed it at her ample chest or nailed her right in the girly bits when she wasn’t looking. With how often Tilda could get distracted by her phone, there was never a shortage of opportunities to catch her unawares and leave her shuddering in pain. He had also rigged up boxing gloves on sticks that would pop out whenever she opened a door or a cabinet, giving her a painful crotch shot. Another trap he was fond of was slinging mousetraps at her breasts and pussy, and she had become well-accustomed to the sharp pain of the metal trap latching on to tender flesh.

Besides his traps and pranks, Luke was also keen on directly harming Tilda’s tender parts whenever possible. If they were on the couch together and Tilda was not paying attention, he might give her an open-handed slap to the crotch or punch her in the closest breast. If her back was turned to him, he might sneak up behind her and swing his fist up in between her legs. He was also fond of giving both front and back wedgies and would twist her nipples anytime he could see them. In short, Luke never missed a chance to get some entertainment out of abusing his big sister’s womanly areas.

Tilda had gotten used to Luke’s constant **** of her sensitive areas over the years, but that didn’t mean that his pranks hurt her any less. Their mother doted on Luke too much to even acknowledge his dastardly pranks. Eventually, Tilda gave up complaining and accepted that there would be no way to convince her little brother to leave her feminine parts alone. If she had to wake up with her underwear doused in hot sauce and pull mousetraps off her tits before going to sleep, so be it, as long as she got enough alone time between the pranks to update her socials.

The young Swede could only hope that the football (soccer ball for you yanks out there) that had flattened her lady lips was the least painful of Luke’s devious pranks. Oh, how wrong she would be…
