The plain sister's heart races on her first date in five years. She practices dildo fellatio, sticking out her ass while looking at herself in the mirror, expecting sex after such a long time. Seeing this scene, I get an erection and forget myself, inserting from behind! It's awkward but feels good... is it the same for my plain sister? Instead of resisting, she flips a switch and keeps cumming with both the dildo and my cock, demanding that I cum inside her multiple times! Her drastic change into a slutty mode is insane considering how plain she usually is!
