End it

You decided to keep looking. It was Tania's goal to make your little sister accept her. It would be meaningless if you stepped in and just talked it out. That aside you never saw Sophie this merciless... You didn't know how she'd react if you approached her now so you decided to wait for her to calm down first. On top of that watching Tania's appetising body getting destroyed by Sophie had it's own visual appeal that you couldn't take your eyes off.

Sophie dropped herself onto Tania's back to sit comfortably. Your girlfriend seemed to be in too much pain to fight back again. Sophie's hands passed under Tania's armpits, her fingers intertwinded in front of her collarbone, locking her hands together to get a better grip in the stunned futa.

Sophie pulled on her own locked hands to bend Tania's back towards her, provoking small squeezing and cracking sounds on the poor woman's back again. Tania's eyes opened slightly from the pain but she was barely aware of her surroundings. Sophie was not going easy on her at all end pulled hard on her hands popping Tania's back slightly more. Tania's eyes squeezed shut and her breathing quickened.

"Ha... S-stop please... You're gonna break m-" another cracking sound interrupted Tania after your sister pulled on her back again. "Shut up, that's exactly what I want" She says while arching her own back to pull even harder on Tania's bone.

Tania started to feel her vision fading and her body was getting numb. She uselessly kicked her legs on the floor but it just made her look more helpless and pathetic than she already was. With one last pull Tania's spine snapped at 90° beneath her. She didn't completly shatter it but there is definitly something broken inside. Tania gasped before her eyes roll back really slowly in her head and her body goes limp under your sister.

Despite that Sophie didn't seem to be done. She used Tania's current position and took the futanari's left arm to wrap it over her own shoulder as if chocking her with her own arm. Sophie pushed on Tania's elbow again and again before a soft cracking sound comes from her shoulder this time. Tania's voluptuous chest spasmed for a second before going back still.

She lets go of Tania's left arm and picked her right one instead to do the exact same. Another small cracking sound comes from her other shoulder but this time Tania's body just jiggles in Sophie's arms without any further reaction. Sophie smilled and pulled Tania's shoulder backward.
"It was about time you stopped reacting. " She happily exclaimed as she moved one hand to hold the **** girl's stomach while the other slid inside her top to remove it completly and throw it to the side, letting Tania's massive F-cup breasts freely bounce down.

Sophie locked her hands around Tania's collarbone again and pulled it back, getting rid of the last tension in her back to make sure she would be down for the next few hours... She finaly let go of Tania who slid back face against the floor, completly knocked out.

Sophie stands up and stretches herself before yawning. "My perfect victory on this slut—ouch..." she trashed before rubbing her throbbing cunt. Tania really did a number on her and she wanted to get back at her no matter what.

"You started this whole thing because of these right ? I'll make sure you can't cum anymore after this." Sophie said with her arms crossed, nudging Tania's balls with her foot. Tania's generous hips danced at the rhythm of Sophie's toes but she remained motionless on the floor.

Sophie gripped Tania's hips and raised them up. she slowly sliding Tania's completly drenched cheeky shorts down along her thighs, exposing both her badly bruised dangling balls and hard throbbing member covered in a copius amount of thick cum. "Of course you're hard... Why wouldn't you ?" Sophie said with an unexpected smile. She licked her lips, while slowly removing the shorts along her legs then tossing them to the sofa. After that she stood back up behind her and raised the **** futanari's legs in the air. It was easier now that Tania's back was more flexible. She held them up leaving Tania's crotch area suspended right in front of her.

*POW* She kicked her so hard in the balls that Tania's hips completly flipped over herself and crashed back to the wall she was on earlier, releasing even more of the cum stocked in her swollen balls. Her body slowly slid down on her shoulders, her arms limply fell horizontally and her legs flopped down, open on both sides of her head— while her dick was aimed at herself, cumming all over her own face and tits.

"You can still cum in this state..?" A sudden idea crossed Sophie's mind and she walked to the opposite side of the room. You watched discretly, wondering where she was going while rubbing yourself and panting because of how rough she was getting with your girlfriend's precious seeds... At this point it didn't matter wether it was you or her crushing them. You just wanted to see Tania's balls finaly be completly crushed and watch all the cum inside of them fly out in the air.

You slowly removed your hand and were about to finish the job Sophie left hanging before noticing her— bolting through the room and jumping like an athlete. She threw her knees forward and violently crashed them right on Tania's poor, sensitive, fragile and defensless testicles...

*CRRAAAAACCK!!!!*

The awaited sound rippled through the room and reached your ears. You bit your lips, Your legs tightened and your eyes crossed as you reached climax from satisfaction, sliding against the wall with a long, muffled moan..

Tania gagged and her body jerked upward from the incredibly brutal **** directed in her balls and pelvic bone. Cum splatted all over Sophie before the younger girl crashes on Tania's ****, pained face with her cunt.

"Aahhhn~" Sophie lets out a long moan and arched her back on Tania's face because of the sudden feeling in her injured sex while getting splashed in Tania's cum. She muffled her mouth and looked down at Tania's dick— releasing everything squeezed out of her crushed balls, directly on her.

When everything was over, Tania's dick started to get limp while her hips spasmed in the air. Sophie slapped and smashed down Tania's broken sack— fiding fun in torturing the poor futanari's crushed gems. "I hope you enjoyed that~ Because these things won't be working for a long~time. Don't even think about jumping anyone like that." Sophie Chuckled sadisticly— patting the defeated futanari's sex while grinding her cunt on her face to humiliate her.

"Honnestly, you really came on me a lot today. Look, I'm all sticky now... I should get back to you, for all the disgusting stuff you did on me... Don't think you can just sleep peacefully now, you pathetic futanari pain slut. You're now my sextoy~" Sophie deposed her arms on her soft and bouncy, naked ass—giggling proudly over the spasming futanari.
