" Well, I guess maybe tomorrow afternoon, then?"He agreed and then got dressed and we went our separate ways.I told Piper that I had gotten my brother...to masturbate while I watched and she as all excited, telling me that I'd be doing it for him by the end of the week. The thought of that sure kept me wet and horny for the rest of school and when I got home, he was waiting at the kitchen table."Ready to watch again, Syd?"I told him I was and followed him upstairs to his room where he was quickly. As we returned to the hotel we were all hungry and thirsty so we went straight to the restaurant for food and beers.After eating lunch my wife said she was going back to the room for a lie-down, James and Annie were going to the swim-up pool bar to carry on, which sounded a much better idea to me. My wife was perfectly happy for me to stay, so she said her goodbyes and went for an afternoon nap, leaving us three in the pool happily working our way through the cocktail menu.They seemed a nice. He unloaded a lot of cum. It was nice and thick, as I hoped it would be. I pulled my hand back, got up on my knees, stroked my hard cock and coated it with his cum and put the rest in my mouth and swallowed it. Before my cum coated cock could get dry and sticky I lined my cock up with his hot ass and shoved my cock in with one move. He moaned and pushed back against me. I was so hot and turned on and he was pretty tight I knew I would not last long. He also looked very sexy with the garter belt. Maybe I should check on her, I say to myself. She might be having a nightmare. I tip-toe over to her and as my eyes adjust to the dark I see her rubbing her little pussy between the sheets! Karin, yes right there! Oh that feels so good, she moans. I cant believe it! She wants me too! If she wanted me like I found out I wanted her then there shouldnt be anything in the way to stop it should there? All the guilt from earlier had left me at that moment, I didnt care anymore that I had feelings.
