"Well big sis we did promise we'd help him out with some tests to analyze and changes at his new size." Michelle giggled as she looked down at Ken in her palm, although at his size he reminded her more of a ladybug crawling on her hand than a person. "But what kind of tests could we run on him now that he's so tiny?" Alex said walking behind her sister and looking down at Ken over her shoulder. Michelle turned around quickly with a different kind of smile of her face then Ken saw before, a smile that alerted Ken that the enormous girl was up to no good.
Ken now held at chest level on both girls, slightly lower on Alex's body while he was forced to look down at her sister Michelle's cleavage "Why don't we sit on him?" Michelle said giggling at her own first thoughts of what to do with Ken now that he had been shrunk. Ken stood up in the young girls palm and yelled up trying to get his friend's attention but wasn't noticed by either her or her thirteen sister as their eyes met, discussing what they should do with him without involving him in the conversation at all.
Alex was interested in the idea that her younger sister had brought fourth but wondered how practical is was to the situation "But, what would we be testing exactly?" she asking bringing fourth the fact that they couldn't conduct a test without purpose. Of course unfortunately for the shrunken boy Michelle had already come up with the perfect answer for her question "Well we'd be testing his durability, to see how much of our weight he could understand under either one of us." she said smiling as she spotted the perfect place to sit.
She began walking her sister following close behind as she placed the one inch tall boy in the center of a leather cushion of the couch he was sitting on earlier while waiting for Alex with Michelle. As Ken looked around him, the two teen girls smiling over him giggling down at him from above as each of them prepared to sit on Ken as they talked amongst themselves once again leaving Ken out of the conversation completely.
"Sooo which one of us should go first?" Michelle asked her sister showing her obvious excitement to feel Ken struggle underneath her petite young rear, which while smaller than her sister's was more muscularly toned due to years of running track since she was ten years old. "Why don't you go first, you weight less than me so it makes more sense. Also we can test his durability more accurately if I sit on him after you(raising the wight)." Alex laughed as she faced her sister towards the couch leaving her shrunken friend at the mercy of her younger sister's butt.
Michelle turned and walked towards the couch, bending over as she looked down at Ken smiling "Ok little guy, you ready to be sat on by my cute little...oops I mean big butt." laughing as she made a quick joke to defuse any existing tension. Ken on the other hand wasn't to happy with his current situation as he yelled up at the gigantic teen "Is there any other kind of test we can do?" not looking forward to being sat on like some kind of seat cushion.
"Don't worry Ken it won't be that bad." Michelle smiled standing up tall over Ken and turning her round jean clad rear over the couch preparing herself to sit down "Who know's maybe you'll enjoy yourself under my cute butt." giggling as she openly spoke about her butt to an older boy. Ken watched as the younger teens massive rear eclipsed the space above him like a large moon or meteorite slowly coming down towards him.
The rough denim of Michelle's jeans began to stretch slowly giving Ken a more clear defined look of her posterior, causing him to become distracted as it hovered overhead "Ready or not little guy here I come!" she teased prompting Ken to look upwards as Michelle dropped her weight towards the couch. Ken's body was smothered by the rough denim as he was instantly pinned beneath the young girls rear which began sinking into the couch with a light feathery bounce upon impact.
Of course to Ken the young girls weight sitting down on top of him felt anything but light and feathery, in fact her gigantic bottom was the most heavy and bone crushing thing he had ever been trapped underneath in his life. Ken struggled desperately for his life underneath Michelle finding it hard to breath since her butt had force him into the depths of the cushion's soft surface far from any air, he only hoped this 'test' as the giant girls called it wouldn't last long. At his size it seemed that the young girls butt was a large mountain bearing down on his puny body threatening to crush him under it's mass.
Ken's wishes would not be granted anytime soon as Michelle began grinding her butt down to the couch as she playfully joked around talking out loud to her sister "I don't know what it is, but I feel as if the couch isn't as comfortable as it used to be." digging Ken deeper into the leather fabric under the rough denim of her jean clad cheeks. "Why don't you sit here and tell my what you think." she teased standing up, Ken meanwhile was glad that he was no longer trapped under the thirteen year old powerful bottom, unaware that a worse threat was on the way.
Ken struggling to breath surrounded by wrinkled leather all around him taking the form of rigs to show where the young girls butt had sat down, however when Ken finally opened his eyes he didn't see Alex or Michelle's face looking down at him as a shadow overcame his body. Ken couldn't believe his eyes as he looked up to see a large butt that rivaled Michelle's rear in size completely, showing that Alex not only had a more sizable ass than her younger sister but by the looks of it a more toned booty as well.
Ken yelled out hoping for mercy finding it hard to move out of the way after his most recent experience under Michelle and was looking forward to enduring even more weight and intensity under Alex's daisy duke like shorts. Just bending over pulled the ridiculously tight short close enough to her body that Ken could see parts of her round butt-cheeks showing and a flash of what looked like dark red panties hugging her ass closely.
"Alex what are you doing?" Ken asked unaware that both girls planned to sit down on him to further test his durability to being crushed underneath them as a seat cushion for their rears. Of course like her sister Michelle, Alex had a well toned butt thanks to her years in color guard, with added width and size as a result of puberty. Either way Ken knew that Alex's butt was not one that he wanted to be trapped under, the sight of her giant moon hovering overhead was enough to make him pray for Michelle to sit on him again since she must have only been ninety-five pounds where Alex must have weighted in at one hundred twenty pounds, which at Ken's size was a huge difference in weight.
Alex dropped her weight down fully with a smile on her face anxious to feel Ken under her rear just like her sister had already done, Ken letting out one final scream before being silenced once more under Alex's short clad butt. Alex landed with a heavy bounce laughing as Ken's bones began cracking under her weight smothering him between the denim of her shorts and the thick leather of the couch beneath her, If Michelle's butt was like a mountain than Alex's butt must have been a small planet compared to Ken as he found himself pinned under her ass-crack.
Ken's troubles wouldn't simply end by being sat on by the huge girl he had trusted earlier, as an earthquake seemed to strike the couch caused by Alex simply bouncing up and down on his tiny body. Ken screamed out in pain as he was dragged against the thick denim of the sixteen year old's shorts, his body being scratched repetitively smashed under her well rounded butt-cheeks. Alex laughed out having the time of her life as she felt the one inch tall boy fighting for his life underneath her butt like a bug that had the misfortune of being on her seat when she sat down. In fact she had so much fun bouncing on Ken that she continued to do so for neatly three minutes straight until even she knew it had to come to an end since he had survived under her ass thus far, proving that his durability was notable and impressive at the same time for a person his size. Then her mind came up with a new idea to extend her time sitting on top of Ken, having her sister Michelle sit on her lap to increase the amount of weight placed on top of him. Although she knew he might be crushed under their combined weight if they did and that the safe choice would be to move on to the next test which Alex had pre-decided to be speed.
