Jeff woke up for the first time female in a world where everyone's gender alternates based upon the day of the week. It was a Monday, but the first day of his high school's Spring Break, so he spent most of the morning nude, playing with his own new breasts and vagina. He was surprised at how large his breasts were.
Eventually he found his girls day clothes and put on the bare necessities, a simple bra, t-shirt, and jeans, with a tiny pink thong to spice it up. He stumbled downstairs for lunch. His dad, on holiday, was already eating, and his dad's robe was straining to contain some very large breasts. Jeff figured maybe he inherited more of his dad's breasts.
"You spent all morning groaning so loud, like its been a year since you last were female, Jeff. Is everything all right?" Jeff's dad asked.
Jeff pondered for perhaps a second too long, but found a satisfactory answer, "Sorry, Dad, it being Spring Break I figured I had the time to treat myself..."
Jeff's dad winked and Jeff noticed his dad spread his legs, revealing a glimpse of a shiny vibrator tucked very tightly between them. His dad then daintly recrossed his legs.
Soon after lunch Jeff got a phone call from his friend Julie to hang out at her place for the rest of the afternoon. Jeff was surprised at how handsome male Julie had turned out to be. Julie handed Jeff a drink, "I stole a bunch of these from my parents, try it you'll love it... I think they're called wine coolers..."
The next thing Jeff knew his mother was yelling at him to wake up. He couldn't remember how he got back to his bed.
As his mother slowly realized that Jeff was coming out of sleep, her yelling got stronger, "How could you, Jeff?! How could you!?"
"What?" he said groggily, and surprising squeakily. His hand accidentally brushed his breasts and he idly wondered why he wasn't a guy, but was too groggy to make sense of it. Instead he tried to ignore his splitting headache.
"Don't play dumb with me you slut! You're pregnant! You let that jerk Julie have her way with you! You should have known better and worn protection!" Jeff's mom shouted. That got Jeff's attention away from the racket in his skull...
