Slightly weirded out by what seems to have happened to your arms, but not really believing it, you grab a handful of pink jellybeans - the flavor was pretty good. At random, you've picked pink-AB, pink-S, pink-SK, pink-U, and pink-BR, but you don't have time to notice this before shoving them all in your mouth. You chew and swallow, and things get really weird, really fast.
A weird tingling sensation covers and fills your entire body, a mysterious energy flowing within you and without you. Your legs become slender and shapely, losing all their hair, just as your arms did, your hips expanding, your feet becoming smaller and more delicate the way your hands did (though not enough to cause balance problems.) Your entire figure becomes softly curvy. Your dark brown hair becomes soft and silky, falling down to your waist as your face softens and your features become finer. As you begin to understand what's happening, your chest expands into two modest-sized breasts, and the final change takes place inside your shorts - you're now a girl.
The tingling leaves your body, migrating to your now ill-fitting clothes and becoming a staticy prickling. Your grungy red T-shirt becomes a crisp, freshly-ironed, and immaculately clean white blouse. Underneath, a plain white brassiere forms to support your new breasts. Your boxers become plain white panties underneath your changing jeans, which become a knee-length blue denim skirt. And, although you didn't consume a pink-SS jellybean on account of there not being any, your battered tennis shoes become black leather pennyloafers as your dirty socks become clean calf-length white stockings - perhaps that was covered under the pink-SK jellybean.
"Oh my god," you murmur in you new soft alto as you look yourself over - you've gone from an average-looking guy to a modestly cute girl...thanks to jellybeans? Jake and Ryan just stare at you, speechless. "Excuse me, Miss," says a store attendant who's walked up behind you, "I believe you've sampled enough jellybeans; I'd like to ask that you not take any more unless you plan to pay for them."
You nod and, realizing what the pink and blue jellybeans must be for, you dig around in your wallet-turned-purse, planning to buy some blue jellybeans and turn yourself male again. Unfortunately, you find that your purse is devoid of money - you must have left it at home!
