After taking a plane ride to Saudi Arabia and viewing the town (for some reason, it looked more like Tijuana Mexico), my family (dad, mom, little brother and sister) went to a nearby bathhouse.

To my surprise, my whole family ended up in the same room as mine. I saw my little sister and my mom naked, which was giving me an erection. I grabbed some swim shorts and covered my erection and began showering it off.

Now, I don't have any problems with nudity, nor do I have any attraction to my mom or my sister. But it did catch me by surprise to see them like that.
