Amanda was excited as today was the town's annual Summer Harvest Festival. There's tons of fun games and activities but what Amanda was most thrilled for was the food, there'd be tons of displays of people's home cooked food and various fresh crops to choose from. Amanda went from display to display, sampling various fresh crops such as bell peppers, tomatoes, grilled corn on the cob, and various other goodies but was stunned when she reached the last row of displays. An out of town farmer had a display with various giant watermelons being sold by the melon and Amanda had to get her hands on one of them. 

Amanda walked up to the display and saw that the massive watermelons were too pricey for her. "Excuse me but are you offering samples for these watermelons?" Amanda asked the man working the stand.

"I'm sorry ma'am but I sell these melons whole," The man paused and gave Amanda a once over. "Though for a young woman like yourself I can part with a one for free, my treat." The man slapped one of the nearby melons as he slid it across the table towards Amanda.

"You're too kind sir!" Amanda gleefully thanked the farmer and picked up her watermelon, struggling to carry it with both hands. She decided to head home as she had already been to most of the displays and she didn't want to lug this behemoth of a melon around with her, and she had a long day of working on her garden tomorrow and wanted to be rested for it.

The following day Amanda woke up at the crack of dawn to get started on her garden before it got to hot, working diligently up until the evening where she decided to eat some of the massive watermelon to rehydrate herself and fill herself up until supper. She worked up a larger appetite then she originally thought and ended up eating the entire melon in one sitting, feeling re-hydrated and re-energized she got back to work on her garden.

As she continued working throughout the evening Amanda began to notice a heat and uncomfortable feeling swell up in her chest. Amanda began to open up the top buttons on her shirt, trying to alleviate the uncomfortable heat, but her breasts suddenly surged forwards and toppled her to the ground. Amanda's breasts were easily the size of the watermelon she had recently eaten and as she played with them, attempting to keep her modesty, she realized that her breasts were much more sensitive. Amanda continued to grope her own breasts, fruitlessly trying to play with her nipples that were barely out of reach until she brought herself to a powerful orgasm and passed out.

Amanda eventually awoke, feeling the grass on her back, and was surprised as she tried to get up due to her new massive melons. She eventually managed to get up, struggling to keep her balance due to her changed center of balance. Amanda was flabbergasted about the changes to her body but, over time, learned to love her new breasts and their sensitivity.

Amanda continues to work on her garden in her free time, though now with her pendulous tits on display, as she could not find any shirt or bra big enough to cover her modesty. She couldn't wait until the next festival so she could display her massive and juicy melons.
