Martha was sitting in traffic on her way to her mother's house worrying about what would become of herself. She now currently had male genitals larger than most males and she wasn't even a quarter of the way through the full trial. While right now her change was hide able she feared she would soon be unable to keep it a secret from her son or other family members. The only thing that brought her hope was the extraordinary payment that she was getting from the trial. Martha could hopefully live off the money until Ero Tech the company funding the trials made something to reverse her problem.
A little while later Martha was exiting her car infront of her mother's house. Her mother was Eliza a 51 year old elementary school principal. Martha's father had left her and her mother when she was young and hadn't heard from him since. Eliza approaching her retirement had recently begun dating again and was currently seeing a nice older gentleman named Nicholas.
After waiting at the door for a while Martha was greeted at the door by her mother wearing a modest one piece swimsuit that was struggling to contain her mother's large bust. Martha had seen her mother in a swimsuit before given that Eliza had been a for a time a swimsuit model before she had become a teacher then principal, but this time Martha felt a twinge of arrousal. That feeling went away as soon as her mother started to speak and usher her into the house.
"Sorry for making you wait I was trying to finish Peter's swimming lesson before Rebeca got into the pool" said Eliza pointing towards her backyard where the pool was. Rebeca was an old friend of Eliza's from when they were both swimsuit models trying to make enough cash to put themselves through college, but where Eliza had succeeded and got her degree Rebeca had changed her goal and became a model full time foregoing higher education. Rebeca had later gotten married to some rich guy and then shortly divorced after he cheated on her with a younger model. She was now living off investments that she had gotten with the money she got in the divorce.
"Could you please tell Rebeca that your are here to get Peter while I show him where the pool towels are" asked Eliza pointing towards her room where Rebeca supposedly was.
"Sure" answered Martha as she watched her mother walk towards the backyard.
Martha was preoccupied thinking about the arrousal that she had felt towards her mom when she opened the door to her mother's room to be met with a huge plump ass. Rebeca was in the process of changing into her swimwear and had just leaned over while pulling down her panties exposing all of her cream colored ass and clear tan lines.
"Oh Martha you scared me there, thought you were Peter for a moment. Wouldn't want him seeing these at his age" said Rebeca as she turned to Martha exposing her naked front and lifting her truly impressive j cup breasts. Martha stood shocked and the twinge of arrousal returned stronger than before bringing a growing pressure in her lower garments. Seeing the shock on Martha's face Rebeca said" oh come now we are both girls here you don't have to look so shocked and yours are pretty big too".
"Sorry just wasn't prepared" answered Martha snapping out of her shock but not stopping the bulge from expanding in her underwear. Rebeca then turned back around and grabbed a strange looking piece of fabric out of her bag and then put it on. Martha now felt the pressure in her undergarments turn painful as she witnessed a woman she had known all her life pose in the smallest micro v-string bikini she had ever seen. Rebeca was enjoying the attention when she noticed something strange about crotch of Martha's skirt but before she could comment on it Martha started to back out of the room saying that she had to get her son and leave soon.
Martha tried to hide her erection as best she could while she packed her son's laugage into her car hoping that he would come out soon. Lucky for her Peter came out to the car soon waving back to his grandmother and a towel clad Rebeca. Before she could be questioned she bid her mother and friend farewell and drove off with her son.
