Karyn arrived home just as her parents were finishing dinner. She sat down to chat with them for a while. Both of her parents stood up to clear their dishes and tidy up a bit which gave Karyn a chance to observe them. She decided to swap something between just for the fun of it. She first scammed her mum and then her dad and then looked through some options. She decided it would be funnier to keep everyone unaware and with that set decided decided to swap their chests. It happened very quickly and neither parent seemed to notice anything.
Karyn had to work to keep her jaw from dropping when her dad came back to the table to grab some more dishes. He was sporting a big pair of boobs, pushing out the front of his t shirt. As he reached one hand down to grab a plate he scratched at his chest with the other hand as if it was the most natural thing in the world. His unsupported breasts were bouncing and jiggling with every move he made. This constant movement was even more unsettling to Karyn and she decided to fix it.
She found the option to switch her parents underwear and quickly activated it. It would be much more respectable for her dad to be wearing a bra now since he was the one with the biggest boobs in the family. What Karyn didn't think of at the time was that this latest change would also swap the rest of her parents underwear too. Karyn watched her dad reach into his t shirt to set one of his bra straps straight on his shoulder. She saw him grab the frilly, purple elastic strap and stretch it out before placing it back flat on his shoulder. She didn't know it at the time but her dad was also now wearing a matching pair of very frilly, very silky, purple French cut panties under his jeans.
Karyn's mom had finished up her chores and came back in to sit with her daughter. Karyn was amazed to see her mom sitting down with a flat chest underneath her dress. Her dad came back into the room to say goodbye to them both. It was a Thursday night and then meant poker night. He met up with 4 of his friends every Thursday night for a friendly game of poker. Karyn would have loved to be able to go this week to see how his friends would interact with him now that he was rocking a big pair of boobs under his t shirt.
