Mom and Dad make us share a hotel room while we are on family vacation because the hotel is overbooked. Im really annoyed that we have to share. As I unpack I notice I left my bikini at home, I just want to go to the beach. I ask if you can quickly go to a store and buy me one. After some convincing you go get me a bikini like a good Brother. You come back to the hotel room and give it to me. At first I think you are joking...I can't wear this in public! It's not going to cover anything. You tell me it will be fine and I put it on to show you just how tiny it is. It doesn't cover anything and my tits keep popping out. I show you my ass and how its not covered at all, then I see your boner. It's wrong that you are turned on for me but I supposed I can help you get rid of it. You were just trying to help me get a swimsuit so now its my turn to help you. I get on my knees and suck your huge cock. Im very impressed with the size. You are taking a while so I offer to let you fuck me so you can hurry up, I want to go to the beach. I ride your cock until Mom and Dad knock on the door telling us to come down to the beach. They leave and we fuck missionary until you are ready to cum all over my face. You cover my face in cum.
