SSIS-169 Even though she is beside me, her whispering in my ear and teasing my nipples from behind drives me crazy. Her little devil sister miru

S1's proud perverted genius miru and the rising star M male director finally collaborate! One day, my sister's boyfriend comes over. He's full of himself but he's really pathetic! To test if he's good enough for my sister, I play with his nipples to seduce him, and he reacts intensely! When I whisper dirty talk in his ear, his dick gets hard! He even cums while his girlfriend is right there, what a loser! But maybe I want to bully him a little... laugh.
