Sister Made Me Cum TWICE

Mom and dad dragged us all the way here for a "family vacation" but decided to leave us by ourselves. Here my sister is complaining again. I noticed she's wearing a short dress and no panties.. That little slut. Maybe I can find something for us to do... She's pretending to take a nap with her ass showing for a reason. I'm going to walk over to her, take my dick out and see what happens.. I didn't expect this to be the best pussy I've ever had. Her pussy is sooo tight and warm that I couldn't stop myself from cuming twice. Best vacation ever!
