Jeff scrolled through the list and saw the option menstrual cup. He didnt really know what that was but it definitely sounded like a better option than toilet paper. He clicked it, and decided to set it to nearby mode, it cant hurt much since he lives alone with his 16 year old little sister. He then set the time, he thought he hit 1 hour but while scrolling through it went all the way down to permanent.
Soon after he started to transform, he felt himself shrinking down and changing into a latexy little cup. Then he bkacked out. When he woke up he was in a dark area amd he coildnt move at all. Where was he?
"Ugh i hate being on my period soo much..."
That sounded like his little sister, uh oh.
"Damn, im all out of tampons, guess ill have to use that stupid cup that mom bought me ages ago. Hope its not weird feeling."
Jeff suddenly was flooded with bright light as the drawer he was opened up. Then he could see his little sisters face peering down at him. His little sisters hand picked him up and he saw she was carrying him towards the toilet as she pulled down her pants and panties and sat on the toilet. She used her other hand to pull out the used tampon and dropped it in the toilet, and it looked like a heavy flow this month too. Jeff was carefully folded into shape and his world went dark again as she slowly pushed him into her vagina, which was not currently at its cleanest. Unfortunately he could smell and taste everything too, how lomg was this gonna last?
