He had only the lightest dusting of dark hair around the base of his cock. We all frolicked around in the water, having a good time while we waited fo... the beers to cool off. Then we sat out in the warm sun and enjoyed the refreshing drinks. We all chatted happily, joking and teasing each other. Then suddenly Greg said, 'Hey, Craig, why don't you and Nick give us a show?' 'What are you talking about?' I asked. 'Come on, we all know that you and Nick are crazy about each other. Why don't you. "Bathroom!" I gasped, willing the pounding in my chest to slow. You raised an eyebrow and gestured with your thumb over the back of your chair. I felt a little stupid when I realized I'd missed it when it was so close. I stood up carefully, giving up on hiding my arousal as I felt my soaked panties sliding over my pussy. I took two steps towards the door before turning back and meeting your eyes once again. "Sixty. Seconds," I growled at you. I said it like it was an option. I think both of us. She found me harder than ever, and gasped a little when she touched it. It was the first time she had touched or seen one on a grown man. My boxers slipped off onto the floor and I stood before her, naked. She took my hand and pulled me down onto the bed again, with me on top. I kissed her deep, and she answered with a powerful embrace. She let out a few muffled moans, and whispered, "I love you." in my ear. I let my hand slide down her beautiful body, tracing a line with my fingers. I crossed. She started squeezing my cock through my pants. She told me that Grace said she found it so hot and wanted to see the two of us fucking. With that Grace came out of the bathroom with just her panties on. I was floored. My sister walked up to her and they started making out. My sister grabbed my hand and pulled me into the bedroom. She told me to strip and to lie on the bed. I was dumbstruck until she forcefully started to strip me. When I was naked and laying on the bed on my back with my cock.
