We dealt with the expected crowd at check-in and that was when we discovered the oversight of only two rooms. My dad offered to share a room with me, so the two sisters could share a room. She immediately protested, saying she was not going to ruin the trip for them and that she and I would figure it out. She grabbed her room key from my dad and we all agreed to meet by the pool bar in an hour. I turned to dad, shrugged my shoulders and followed her to our room. We unloaded our luggage, laid down on the bed for a few minutes before she walked into the bathroom to change. She came out wearing a hat, sunglasses, and her bikini with a sarong tightly wrapped around her ass. I had changed while she was in there, so I grabbed my cap and sunglasses and we headed to the bar. She put her hand in my arm, reminding me that I was her date and from that point I needed start acting like it. I chuckeled and asked her what that involved. She said I would need to act like a boyfriend, fetching drinks, applying suntan lotion, and pretty much anything else that would make her happy. Also, I would need to stop calling her aunt Carol. I could call her Carol, honey, or babe. I told her I would be the best boyfriend she ever had. We both laughed as we were arriving at the bar.
My parents were already there, with a drink each in their hand. They also had a wine waiting for her and Coke waiting for me. We sat a the bar for a few drinks before deciding to find some lounge chairs to hang out by the pool. Mom and dad walked ahead of us, as I walked over to Aunt Carol to offer my arm. She looked up at me and gave me a happy smile. We lucked out, finding four empty lounge chairs. They were laid out with two in front and two in back. Dad and I took the two rear ones and mom and her sister taking the two in front. By now, they were in several drinks and feeling no pain. Me? I was completely sober with 4 Cokes. Mom and her sister got up to go to the restroom and I discovered something that had been under my nose the whole time. Mom looked fucking hot in her bikini. She always wore a one-piece at home, but I suppose she bought a two-piece for the cruise, thinking it was going to be my aunt’s fiancé coming and not me. Her ass looked just as tight as her sister’s with the bikini that look a size too small on her tight, sweet ass. Why had I never noticed? As they walked away, my dad asked “So, who do you think had a nicer ass?”
“Mmm, I don’t know”
“Your mom’s not bad for a 40 year old sexy lady, huh?”
“No. It’s…it’s…uh…nice.”
We stayed quiet while staring at them while they walked away. Both Carol and mom were fucking sexy in their bikinis with slim waists and tight butt’s as they walked away. Looking around, I could see several other guys checking them out. They soon returned and took their seats with a fresh glass of wine in their hands. Dad got up to us the restroom and I decided to stay behind. I closed my eyes and enjoyed the sun while mom and Carol gossiped about people on the ship. They soon started talking about Brad and how she had found out and what a pathetic loser he was. That was also when aunt Carol mentioned that he had not been fulfilling his duties for the past several months and that she was very horny. They must have forgotten I was there. I almost gave myself away when I heard Carol say “I am so horny, I might even take advantage of your son.” My mom’s reply was certainly not expected “Go ahead, I’m sure he would enjoy that.” They both laughed with my mom continuing “The way he was undressing you with his eyes last night by the pool, I’m sure he would be up for the challenge.” They soon went back to mocking the people around us and dad had made his way back, explaining he had gotten lost.
