Washington high spinoff by Mickeybb Lucy and Carl

Lucy was still excited at watching Heather stand on Carl's nut. She definitely needed a turn. As she and her mother helped her brother back up, she looked at her mom.

"Mom, since Carl's nuts are basically indestructible, can I try testing them again as Heather walks down the beam to the next boy? Please! I'll only stand on it for a few minutes, and maybe stomp a few times. The nurse said it hurts him, but no real damage. Plus even if I ruptured one they can fix it. No big deal."

Barb thought for a moment, sure Carl might feel a little pain but Lucy was getting her period now and had to deal with pain all the time. Modern medicine had come a long way and ruptures were no problem now.

"Okay, sweetie. But remember his nuts being huge makes them strong but they're very sensitive. You can step on them on the beam for up to 10 minutes and maybe a dozen stomps or so, certainly not more than twenty. Are you going barefoot or keeping your puma's on?" Her mother asked.

"Well, how about 10 minutes standing, 20 stomps with the sneakers then another session barefoot with the same numbers?" Lucy suggested with a sweet smile that seemed like she would enjoy trying to rupture the indestructible nuts.

"I'm starting to think that you might enjoy standing and stomping on your brothers nuts. But I guess we will have to test him regularly to make sure he is ok for self defense practice. Okay, but if you rupture one he might be angry. It could really hurt, you know."

"Oh mom. It's only his nuts. Now help me keep my balance when I step up."

Lucy climbed up on the balance beam and the sensation in her groin was certainly going to be more fun than the sensation Carl's groin was about to feel. She gingerly placed her size 7 puma on Carl's left nut. It felt so good! She twisted and pumped her foot in the large swollen mass and unlike Heather, she loved the sound of the cartilage being crushed under her pretty foot. She decided to place her heels on both of his massive orbs, so she turned to the side. She realized this put her butt against her brothers face. She giggled as she continued to dig her heels in and felt the breath escaping Carl's mouth against her butt.

Carl was in a world of pain, as Lucy kept lifting and dropping her shoes carelessly on his nuts which were so very sore and swelling even more. He felt a little relief as Lucy stepped off and his nuts began to return to their original spherical shape, although they now had a tread imprint from his sister's shoes, a fact that caused her to giggle again.

"So funny, look mom you can see my tread on his nuts. Okay, bro time for some stomping. Mom said just twenty with the shoes on then we can try barefoot. Are you ready?!?" She didn't wait for Carl to answer and stomped super hard on his left nut, then a quick follow up on the right. She was having the time of her life and knew Carl's indestructible nuts couldn't last. This was too fun. She would destroy them for sure eventually. And have tremendous fun trying. She finally orgasmed as she got her twentieth stomp in. She wasn't counting out loud and since mom didn't say anything and Carl was only making high pitched mewling noises, she just kept stomping. She probably got in an extra 20 and loved it.

"Okay, mom. That was twenty I think."

"I lost count honey, I know it hurts him, but I think you can do another 10. Then some barefoot fun." Barb said, as she was strangely turned on watching her petite daughter stomping her son's huge nuts over and over and over.

She smiled and stomped thirteen more times. Then stood with her right shoe on his left nut and lifted her other foot in the air to take off the sneaker.

"Carl, I've been in these all day do they stink?" She asked her brother as she lifted her sweaty puma to his nose.

"A little bit, but that's okay" he replied with a higher than normal voice, and strained speech with her full weight on his nut.

"Here I'll let you suck on my dirty socks for the barefoot session," as she stuffed her sock in his mouth. She repeated the procedure with her other shoe, and now could step on his balls barefoot and feel as well as hear the damage she was wreaking on Carl's nuts.

She shifted her weight several times but was running out of creative ways to bust poor Carl's nuts. She just commenced with the stomping. She used her toes, the ball of her foot and her heels, stomp after stomp.

"I guess that's twenty mom." Lucy said with a dejected tone of voice after her 33rd barefoot stomp, sad to be stopping stomping on those huge balls.

"Sorry Lucy, I lost count again. Carl I was going to try some too, which is why I had Lucy go easy on you." Both Carl and Lucy looked surprised that she considered Lucy's ball stomping and standing as going easy. "I'll probably help test you a couple times this week, but I won't do it here in public today. I know the nurse said they are extra sensitive being so large, but you're doing great, so can Lucy stomp on them some more since I'm not joining. I really think she's enjoying helping you with this. She can jump on them if you lay down on the matt, she can't do it on the beam since she could fall. When we test at home maybe she can wear her soccer cleats. That would be a thorough test."

Carl was dumbfounded. Did his mother really think he could take this. His balls hurt so badly he was barely conscious. He didn't want to disappoint mom or Lucy though. He looked at his sister and saw her sweet, yet devilish smile.

"I guess I can take a little more, mom. You're right that Lucy seems to enjoy 'helping' me. Not too many jumps though please, my nuts are really sore and someday I'd like them to help me be a father, so they have to survive all of the testing, trampling, stomping, and jumping."

"Sure honey, we know how much it hurts," even though she and Lucy really didn't, "we'll make sure you can reproduce when the time comes. Plus ruptured nuts are basically easy to repair, even if it is uncomfortable for the guy. And the nurse says yours are basically indestructible, that's almost a challenge hahaha. Now just lay down and let Lucy have her fun testing your nuts."

Carl laid down and spread his legs as Lucy walked up to him and stepped up on his groin. She managed to flip his penis up so she had her toes and the balls of her feet on it, as her heels settled in on his nuts. She didn't know what came over her but she started rubbing her foot up and down on his cock that started swelling to an even more massive size. Was it wrong to basically jack off her brother in public? Probably, so she took it about as far as she could, but before he could feel the first pleasure of the day she stopped and stomped her other foot right on his throbbing nuts.

"Owewwew, Lucy please. That hurts so bad." Carl cried out.

"It's just your nuts, silly. It's not like you slammed your finger in a car door or got poked in the eye or something." Lucy said.

"I would much rather slam my finger in a door or be poked in the eye than having my nuts kicked, stomped, trampled and jumped on." Carl responded with the first hint of anger after all the testicular trauma he had endured today.

"First of all, I haven't started jumping yet. Second of all, would you really prefer that I poked your eye?"
