Slow Sterilization (Part 3 Mako the Eldest Sister)

All characters are over 18 years old and growing older every day… Just 3 step sisters ballbusting at their mother’s direction.

Mike woke up and had to pee again. As he tried to get off the floor but the pain in his balls buckled his knees dropping him on his already bruised face.

He screamed at the pain in his broken nose, but the searing heat in his groin was worse. He managed to get up to his feet and staggered down the hall and sat on the toilet and relieved his bladder.

Mike was just trying to decide how to stand up without hurting his swollen pain filled balls, when his stepmother Mei came in followed by her eldest daughter Mako.

Mei was unbelievably hot for a woman over 40. She was wearing a black lacy bra beneath her neglige. As usual her bra was one size too small, forcing her big boobs to squeeze out all sides.

Mike’s head was still cloudy so he was caught staring at Mei’s side boob and didn’t see her arm moving towards him. She wasted no time slipping her hand around his ball bag.

Mei wanted to grab both of his balls but they were too swollen. She settled on his left nut, wrapped her fingers around the testicle and got a good grip. Mei squeezed her fingers deep into his ball and pulled him up off the toilet.

Mike stood up fast, following his balls. Mei kept pulling up until he was on his tiptoes and openly crying. Mei squeezed harder and yanked his balls left and right, then left and let him fall into Mako’s arms.

Mike’s face fell right into her cleavage. He moves his head back and forth trying to stand on his own. But all he did was soak Mako’s tits with his tears, drool, and leaky nasal spray.

Mako reached down and trapped both his balls at the bottom of his scrotum. She pulled him back up to his feet and dragged him out in the hall. Mike stumbled after her.

All he could think about was the pain. Then he thought about the source of his ball pain, Mako. She started bodybuilding in high school and had been into competing ever since.

Mako had dropped 40 pounds since Mike last saw her over Christmas break. She was now down to 7 percent body fat and every muscle was well defined and tight.

Her ass could make diamonds out of coal it was so tight. Her upper leg and lower abdominal muscles disappeared under her tight boy briefs. Her legs were solid as tree trunks, but shapelier than a runway model, zero fat.

Mako pulled him into his room by his balls, squeezing, pulling and twisting them before pushing him against the Saint Andrews cross and dug her nails deep into his nut meat.

Mei walked in and reminded Mako not to rupture his balls, just bruise them bad enough and often enough to stop them from producing sperm. Mako eased her grip and removed her finger nails from his swollen aching nuts.

This was the first time Mike heard anything about making him sterile. He shot a confused and scared look at Mei and she stared back for almost a minute before she threw her head back in a mouth wide open belly laugh.

Mike’s mind was racing, what could he do or say to make her change her mind. He could beg, plead, cry and look pitiful, or even offer to give her his half of the inheritance.

While his mind was racing, he noticed Mako step in front of him and take off her pajama top. He stared at her magnificent breasts. Fully half of her tits were made up of her pectoral chest muscles.

This made her boobs defy gravity. Full on natural D cup titties were within his grasp except his hands were chained out at his sides. She used her pajama top to wipe his drool and tears off her chest.

Mia reminded Mako of her morning gym workout. Mako said she had a half hour before she had to leave, but she could warm up on her stepbrother.

She knelt before Mike and without warning began speed bagging his bollocks. The air went out of his lungs as he tried to scream. All that came out were tears and high pitched sounds like a little girl sniveling.

Mako changed direction of her fists, now hitting his balls from underneath. She stood and began driving her knees into his groin, trapping both nuts in the space between his thighs.

Now her knees were slamming into his battered balls left, right, left… Her mother Mei started talking to her in a conversational tone about daily events oblivious to his pain.

Mako moved back from Mike and began lifting her legs sideways to work her Adductor muscles on the outside of her solid thighs. As she lifted her legs sideways, she pointed her toes and slammed the arch of her foot into his damaged balls.

Mike noticed her toe nail polish, and found himself impressed by the color and how it went with her tanned legs. He then noticed that since she was standing sideways and topless, her boobs were standing straight up and out giving him a wonderful view.

Her nipples were small, and because they were hard the areola was even smaller all bunched up around her teats. Mike could think of nothing else and was staring to get tunnel vision, his peripheral vision was turning black.

He could only see a circle of light in front of him. The circle of light grew smaller until all he could see were Mako’s tits bouncing with each side kick to his nads. Mike passed out.

Mei allowed as it had been a good morning, and a great start on her plan to sterilize her stepson. She headed downstairs to help her younger daughters Lee and Sue clean up after breakfast.

Mako grabbed her pajama top, went to get ready for her workout but stopped and gave Mike one good hard kick while he hung in his chains unconscious.

Sorry about the delay between chapters, life has calmed down now.
