Part 3: sisters bf in Cabo - night 4

If you haven’t read the other 2 parts to our family Cabo trip, you should for more context.

Our parents went golfing and my sister was hung over so her bf and I decided to go on a beach hike. If any of you have been to Cabo, the beaches are rocky and there are a lot of cliffs. It was pretty hot, mid 90’s, so we would walk for about 15 minutes then have to jump into the water. We ended up near a private gate that lead to a beach house. We snuck around a bit and noticed a hot woman - probably in her early thirties, laying by the pool topless reading a book. She saw us looking over the fence and waved. We waved back. My sisters bf Brock made a comment about how hot she was. She got up and put her top on and walked over to us. We said that we are staying in a house a mile down the beach. We told her the address and she said her husband owns the house we rented! Weird coincidence. She asked if we wanted a beer - we said yes, obviously. Their house was stunning - likely $15M. We sat by the pool with our legs in and she brought us a beer. She asked if we were friends - Brock replied and said we were brothers. Not sure why he said that. She said we don’t look like brothers - he replied and said we have different dads but the same mom. She then asked which one of us had a bigger dick. She laughed and said “I’m kiddinggg”. Brock replied “dude my bros dick is massive. But I have the better ass”. She proceeded to take her bikini top back off. But this time, she also took off her bottoms. She was completely hairless. The best pussy I had ever seen. Brock started adjusting his swim suit and complained that his liner was itchy and slid his suit off exposing his rock hard dick. I was a bit in shock and watched Brock jump into the pool. She dove in also. She swam over to me and asked to see the big bros dick and pulled my shorts down. Brock watched from the other edge of the pool and slammed his beer. She gently grabbed the shaft of my dick and softly stroked it. Brock swam slowly over to us and grabbed her tits. She told Brock to sit on the edge of the pool next to me to compare our cocks. She said mine was bigger but she admired how fit Brock was. She grabbed his dick and said we both have made her month in Cabo. She got out of the pool and told us to follow her under the cabana. She laid down and split her legs apart and told us to both go down on her at the same time. Brock was the first to start going down on her, I lifted her right leg and started licking her thigh and up towards where Brock was licking. Our tongues touched a few times while eating her pussy out and he laughed but kept going. He scooted up on his knees and slid his rock hard cock into her pussy. She told me to lay under him (she still thinks he’s my brother) and lick her pussy while he fucked her. So I did. Occasionally licking his shaft. I started playing with his butt hole. After about 5 minutes, he reached down to me and grabbed my head and pushed it back a few inches and made me lick his balls while he fucked her. So I did. I could feel his body shake as he busted his load in her. As he pulled out, his huge load dripped into my mouth. He pushed me out of the way and ate his own load out of her pussy. We grabbed our swim suits and ran out laughing. Can’t even make this shit up
