Shrunken Inside Step-Sister's Asshole

Description: Our step-parents went out of town for 2 weeks, and put my annoying step-brother in charge. we are both in college, and his is twice as far but they still trusted him more than me and think he's sooo responsible. i knew you would fuck it up somehow so i decided to make a surprise visit home and find the house completely trashed. after documenting everything, i'm so excited to hold this over your head. i love seeing you grovel- you really don't want them to realize what a fuck-up you really are do you! okay then, i'll give you a choice-because i really love this groveling and ass kissing. but i want you to actually kiss my ass. i have this shrink ray that i've been eager to use on someone. i want to shrink you down and keep you in my panties for the rest of the two weeks, kissing my ass the entire time. once you're shrunken down though, i realize i'll have to keep you right in my ass crack to prevent you getting crushed when i sit down. too late to back out now!!
