Barbara

The story starts off with John, a 19 year old boy, sitting at the dining room table with his 18 year old step-sister named Kristal and his father David. They are arguing over some problems that the two step siblings have been going through since they have moved in together. Eventually John's father and Kristal leave and he heads back to his room. Before he can get there, his step-mother Barbara came out of her room. She heard the conversation and told John not to worry because she was investigating some things. As they parted ways Barbara brought up her phone and started to use her new Size Implant app. Unaware of the power she had, John was shrunken down to 5% of his original size, leaving him only a few inches tall.

Confused by what just happened, John crawled out of his giant clothes naked, wondering what he was hearing behind him. It sounded like quakes, but it was actually his step-mom's giant feet approaching him. She looked down and greeted him, welcoming him to his new size. She explained how his recent doctor visit was actually a trick to implant him with a device that was controlled wirelessly. On her phone she had an app that was able to work with his implant, shrinking or growing him to whatever size she wanted. As she reached down towards him, all John could think of to do was run in a panic. However, Barbara was gigantic compared to him and she caught him without any effort. Now with her step-son within her grip she walked out to the living room and placed him on the coffee table as she sat on the couch.

Standing on the coffee table naked and tiny, John was afraid of what Barbara was planning on doing to him. But what came next shocked him more than anything when she told him that she had been looking through his browser history. It turned out that John's step-mom found everything he had looked at online, including his secret giantess fetish. She exposed him by bringing up a picture of a tiny man worshipping another girl's foot. John didn't have anyway to explain himself as he watched Barbara plant her foot on the table next to him. She demanded him to come over and give it a kiss. Afraid of the tone his step-mom was giving off, John crawled over and planted his lips on her big toe. Barbara found this amusing to see her step-son obey so quickly and eagerly. It wasn't long until she would bring her other foot on the table and ask for a foot massage. John got to work right away, rubbing her soles as the giantess browsed through her phone.

Another picture Barbara found was of a shrunken man licking a woman's foot as she used her other to rub an erect cock. John's heart dropped as his step-mom made the connection that he was getting himself off to this. The argument he was having with Kristal involved her missing socks, and now Barbara knew that it was John all along who was stealing them and using them like a little freak. This got Barbara curious as she pulled her foot back she noticed that John was actually getting excited from this. She confronted his hard dick, grossed out, but with naughty ideas on her mind. John was plucked from the table and dropped on the couch as his step-mom laid out on her stomach. From this point the little guy was ordered to start worshipping her feet. He didn't waste a moment before diving into his step-mom's soles, licking and smelling all of her feminine scent.

Eventually John climbed up and started to rub his entire body on Barbara's foot. At first she liked it, but when she noticed that her step-son was grinding his cock on her she made him stop. She sat up and picked him up between her toes, laughing at him as he was stuck between them as she lowered him to the ground. Barbara applied some pressure, showing him just what kind of power she had over him, but also how much more durable his body was at this size. If she wanted to she could crush him still, but at least she could have some fun without hurting him too easily. She let off her foot and walked into the kitchen, expecting John to follow her. The little man ran after her, getting to her feet so he could continue to worship them. But as this went on they were about to be interrupted as a door in the distance sounded like it was opening.

Coming out of another room was Ava, John's older step-sister who was 23 years old. Ava walked out to the kitchen thinking she heard her mom. John thought this was his chance to get help, he tried to run towards Ava, but was suddenly stopped as Barbara pinned him underneath her foot once again. She quickly grabbed her cell phone and shrunk John to 0.1% of his original size, leaving him the size of an insect, hiding him from her older daughter. The two chatted momentarily before going out to the dining room. John knew he had to chase after them and so he did at his tiny bug size. Eventually he reached his step-sister's toe and tried to bang on it, but it was no use. Soon the conversation would end and Ava would leave the house, leaving John alone with Barbara again.

When her daughter was gone, Barbara pulled out her phone again and grew John back to 33%, which left him the size of a larger doll. She was angry that he had tried to escape from her so she took it upon herself to find a way to humiliate her step-son. Using her foot, she started to rub around John's private area, instantly bringing his penis to attention. Barbara wanted to get her tiny step-son off and use it as blackmail. She knew he wouldn't be able to resist as she started to increase her pace, jerking off the shrunken dick without any effort. Barbara told John that she wasn't going to stop and that she knew this was his fantasy. As they moved over to the coffee table she sat down and laughed as her feet took control of John. The little man tried to resist, but his body wouldn't let him. Barbara's toes were just too playful and gave him so much pleasure. Eventually he would lose control and pump his load out as his step-mom continued to rub his penis rapidly.

Eventually things came to an end as John passionately kissed the bottom of Barbara's feet, thanking her for what they just did to him. He had experienced an orgasm like no other, but the fun was now over. She pulled out her phone again and grew John all the way back to his original size. Now with things back to normal she instructed her step-son to put on some clothes and get out of her sight. John was scared of what Barbara might tell others so instead of trying to argue he ran off and went back into his room as she went to work. Hours went by as he thought of what would happen next time they would be alone.

Later that day John came out of his room to find his step-sister Kristal and Barbara talking to each other. He worried that she might of told her about his little secret, but for now she didn't. They got up from the couch and surrounded him, making John raise his guard. In an instant John found himself start to shrink again as Barbara set his size to 2% of her app. Kristal was shocked to see what just happened to her step-brother, but she was not concerned at all. Instead she was excited as she bent down to pick up John who was less than 2 inches tall now. From this point on, John knew things were going to get bad as Barbara spilled his entire secret to her daughter. Kristal was in shock, hearing how it was John this entire time stealing her socks and moving her shoes around.

When the attention got turned back towards John, Kristal brought him closer to her face to notice that he was rock hard. She was disgusted to see her tiny step-brother, especially after seeing all the pictures and videos her mom was showing her. Barbara said goodbye to her daughter, telling her that she would be going out and that they would be alone to do whatever she would want with John. Kristal was super excited to get her revenge. She hated her step-brother and having him under her control like this was a dream come true. Now alone she set him on the ground and chased him around on the floor. It only took her two steps to catch up before she would pin him to the ground with her shoe. This was where John knew that the next couple hours were going to be nothing but torture with his younger step-sister Kristal.

As you fight back Barbara doesn't budge and continues to assert her dominance upon you. Since you are tiny and under her control, she is amused by how turned on you are by her feet and enjoys using her toes to tease your cock, hoping that you are unable to resist her touch until she brings you to an orgasm
