I just came home from the gym. Hey big brother! I had a really great workout! I'm all sweaty now. I have to go for a shower! I strip down to my cute butterfly panties right in front of you, and you try not to look at your little sister's tits. I wrap a towel around me and announce I'm off to the bathroom, but you stop me. You don't want me to go, and you know just how to make me stay - tickling! You tickle me mercilessly while I beg you to stop. I laugh and squirm around until I end up bent over against the wall with my butt against your crotch. Oh my god! Big brother, are you hard? You expect me to be grossed out, but I'm flattered. You're hard for ME? I drop my towel and you get on your knees to worship your little sister's body. You touch my pussy over my panties, then slip your hand underneath them, a finger dipping into my pussy. Big brother, we shouldn't be doing this! We're siblings! It's wrong! You spin me around to worship my ass, kissing and squeezing your little sister's big butt cheeks. I get on the bed on my knees for you to kiss my ass cheeks some more, then drop down my panties so you can get at what you really want. Okay, big brother, it's time for your punishment! I know you've been stealing my panties ... now lick my asshole to make up for it! You go to town on my ass, licking and kissing it, even dipping your tongue inside to fuck me. I can't believe I'm enjoying my big brother tongue fucking my asshole! Finally I flip around, telling you to stop, but I'm so turned on. You go at my pussy now instead. You lick, kiss, and tongue fuck your little sister's pussy until I'm moaning and grinding on your face. Stop, big brother, I'm going to squirt! I pee into your mouth and you swallow it all down. I'm sorry big brother! What? You enjoyed that? You're a pervert!
