Dawn was quite all the way back; I knew her mind was churning. When we arrived it was about 6:00, Beth was inside fixing dinner.
"Hey Beth," Dawn said as she walked up.
"Did you all have fun at the lake?" Beth asked.
"Yes we did. Are Cindy and Mike back yet?" Dawn asked.
"Not yet. Dinner is ready."
"They should be here in a few minutes, they were right behind us," I said.
Cindy and Mike came in a few minutes later. We all sat and ate dinner and talked. Mike brought up the skinny dipping and Beth looked at us and smiled. We finished eating after about 45 minutes. We all helped Beth cleanup so she could be finished for the evening.
"We are going to go take a shower after swimming in the lake and then rest some," Dawn said.
We went up to our room and I started undressing to take a shower.
"Wait a minute before you shower," Dawn said.
Dawn walked over and sat on the bed and motioned for me to sit by her.
"What's up?" I asked.
"You really want to do this?" Dawn asked.
"What do you want to do?"
"After we shower let's get on the bed and have some noisy foreplay. I am going to leave the bedroom door open about an inch or two while we shower and after we come out. If Beth hears us and comes up she should be able to see us on the bed through the opening in the door."
"Ok, if you are sure?" I asked.
"It's just Beth," Dawn said.
Dawn got up and walked over to the bedroom door and opened it so that it had about a two inch opening. Then she led me to the shower where she left the door open to the bathroom.
When we got in the shower Dawn was cutting up and laughing loudly so Beth would hear. We spent a lot of time soaping each other up; I was getting turned on just thinking about pretty Beth watching. We got out of the shower and toweled off and went in to lie down on the bed. Dawn continued laughing and teasing me and got me laughing. I was sure Beth could hear us where ever she was in the house.
"You want to fuck me big boy!" Dawn said loudly. "You want to stick that huge cock in my sweet little pussy!"
I was sure Beth had heard that, Cindy and Mike probably heard. Dawn laughed and grabbed at my cock as she played around on the bed.
"Damn James you are hard as a rock, did you get excited playing with my pussy in the shower?!"
"Dawn, be quiet, Beth will hear you," I said for effect.
We played around in bed more, Dawn was stroking my cock as I played with her tits while she laughed.
She leaned over and whispered in my ear," I just saw Beth peek through the door, you ready?"
I whispered back in her ear, "Make it a good show honey."
"James I want to suck your big cock. Stand up at the end of the bed."
