We're on vacation nd we're stuck in the same room, my friends aren't texting me back so all I have left is to hang with you. You comment on my bikini, do you like it? Don't check me out, I'm your sister.. or do.. I know I'm hot. I like teasing you in it.. I see how hard you're getting and tell you we should sneak into the shower. We really shouldn't be doing this but I end up sucking your dick and fucking you in several positions. Mom knocks on the door as you're cumming inside me. You filled me up so much omg!! I'm your sister!! What if I get pregnant?
