The lights were off and I wanted a better view so I turned them on briefly to see it up close. His was totally out by now and before I pulled the cove...s over him for the night, I leaned in really close and kissed the head of his dick. It actually moved some over my warm lips and that's when I decided to go for broke and just pop the head in my mouth for a second or two. I did it and then panicked, thinking he would know and I covered him up and turned off the lights. I went to bed, with a semi. "Can I see it?" she asked. "You don't have much of a choice after what I just saw." "Oh, well that's OK. I like being dominated and forced to do things anyway," she said and gave me a wink. Hearing these things from my own innocent looking little sister drove me crazy. I unzipped my pants and pulled out my 9" hard cock and she was in shock. She just stared at it until finally, she did the last thing I expected. She got down on her knees and engulfed my entire cock with her mouth, fitting in as. I told her I was going to shower in the guest bath , she said I laid you some cloths out , will you do the same for me? OH yeah I get to pick out what she is wearing up there...and if I'm correct it'll be just me and her for the ride. I'll pick something sexy out. I heard her shower going so I went in our room and started going through her dresser drawers. Umm the mountians and a lake...what should I pick out? I found a pair of light tan denim short shorts , and I added a white wife beater . No. I backed away and went back to our cabin. When I got there I changed into something I could wear for the evening. About an hour later my iPhone chirped that I had a text. There was no cell phone service on the ship, but we did have internet access and my phone used the internet for text messages and email.I looked at the message. "Where are you Sweetheart?" It was from Danni. I didn't bother responding to it. I was hurt. Okay, I think it's a bit hypocritical to pretend that my heart was broken..
