We were all eating lunch and I kept looking at crystal in her cute little towel and Mary noticed and said looks like my brother.liked seeing you naked lol. Crystal said ya and I can’t.blame.him and so she stude up and pulled her towel.off. Mary spat her drink.out and my dick just got.rock hard. Crystal looked at Mary and said.u told.us to have fun and get along. At.least if.I nude he won’t be.rude.or anything. Mary just blushed and staid ok. Then the black.haired girl from early said speaking of being rude I said.this.is a nude.place.only while she looked at Mary. Mary said oh please I to embarrassed miss…. Sam the lady said and.I.the life gaurd and that’s to bad and then she yanked marys towel off her and walked away and for.the first time.ever I saw my sister naked. Her tits were amazing. Huge and.her prissy was.sexy. small.I never.thought of my sister.in a sexual way before but I almost came right away. Crystal stood up and tried to cover Mary with her own.body but.it didnt help at.all. Mary just.looked at me and started.to cry.she turned around and started.to run.towards a tent.they have set up and.I saw.her.perfect ass. Crystal ran after her and.I just waited on the sand. Crystal caught up to her and asked if she was.ok. Mary said no. My own brother saw me naked and even.had a.Bonner. Crystal.said I know but maybe.it’s a.good thing. It will bring you two closer and u don’t.have.to be.scared.about being naked in front of anyone anymore. Mary stoped crying and said well I guess.that’s true we can start having fun now.
