you find a door with "next" on it. the sign lit up a moment after you started looking. they are probably looking, you think.
the next room has some swimsuits on display. they looked quite proffesional, at first glance not meant to pull eyes. you think what to chose as last time the gas made you fit in to these clothes, making you 'bigger'. this time you look if the size is mentioned. it is. you'll try the small one.
maybe you should have expected it. you only manage pull the swimsuit up, but not the top part. you stand a bit silly the changing room. you manage to ignore you naked body till now. this small swimsuit was actually very high leg one piece swimsuit. it looked a bit riske because how tight it is on your body and you failed to get the chest part of swimsuit on because your huge breasts and because it wasnt tall enough. while struggling with it the fitting sealed and the bitter gas started to flow. you got quite excited this time because of your look causing your knees to buckle a bit. you saw yourself shrinking in height but to your surprise your ass grew. your legs grew a bit more fit and defined. your upper part doesn't seem as effected as your breasts became a bit tighter and perky, but staid big. you now have a very big ass. looking in the mirror, you notice it was as fat, but bit more firm.
the cabin unseals again and you put on the yoga shirt that still fit well enough and exit with half of the swimsuit on letting the top part hang in front of you. you actually needed move a bit sideways to get out of the fitting room.
