Friends Saw My Mom's Boobs

I'm 18 years old and male. Recently my family and I flew down to the south coast from joburg for a holiday. We brought my one friend with us as he doesn't get to travel much because he's family's not well off. So because of this my brother also brought one of his friends

We decided to visit the Mpenjati "nude" beach as we heard so much about it but we didn't expect to see anything due to the political issues surrounding the area. Let me first say, my mom is a very free person. Nothing is off limits to her so she was excited for this.

We decided on a Friday morning to head early to the beach. When we reached, we saw three couples on the beach, one had two small boys and one had a girl and boy. All the men had their shorts on but the women were completely topless, which kind of shocked us as we didn't expect this. My mom got used to it quite fast and she then asked if we wanted to swim naked, we all said no. She said that if all the other moms are topless, it wouldn't be bad for her to go topless aswell. Me and my brother hesitated as we didn't want our friends to see her boobs. It would be so akward. We both said no.

My friend jumped in and told her that he's not uncomfortable with that and it's a good experience for her. He's just a little pervert and I knew what he was doing. Without hesitation, she pulled off her bikini top and started laughing.
I couldn't even think straight. There was my mom, standing completely topless with both her boobs out in front of our friends.
I screamed and asked her what was she thinking. My dad, being so calm, just told me to let her have fun. So we left her.
It was akward at first but after our friends stopped staring, for which felt like an eternity, it wasn't so bad.

Mom just laid on the sand and sun bathed while we went swimming. We all four were just sitting in the small tidal pool when my friend starts talking about her boobs. He said he had never seen someone's mom's boobs before and that they looked amazing.
I instantly got hard. The thought of our friends knowing what our moms boobs look like was amazing to me. I jokingly encouraged them to sneak some pics of her, which they did, just so I would know that they could look at her boobs whenever they wanted to. The other guys also saw them which turned me on even more. I want all my friends to get to see her boobs after this.
