On your European vacation with your step-sister, your shared hotel room has an unexpected twist: a shower open to the room!! You agree this is awkward but fine, you’ll be not awake while she showers anyways. However, the sound of the shower wakes you up, and as much as you want to be a good, “normal” step-brother and give her privacy, your inner voyeur gets the best of you. Of course your little step-sister notices, and puts on a taboo, teasing show! ♡Tags/Themes♡ big bro x lil sis, exhibitionism, situational taboo, body pressing against glass, pussy play, heavy teasing, moaning, soapy shower play
