Plot Summary

My sister's friend is visiting our house, and her skirt is so short that her panties are completely visible. She's doing it on purpose. I playfully lift her skirt, and she's panting with excitement, revealing her masochistic side. I perform a physical examination in the next room so my sister doesn't notice. I shove my adult cock deep into her throat, play with her panties, and then insert my adult cock into her wet, smooth slit.
