My sister in law handed me a cold beer as I sat back viewing what only could be described as heaven 3 young birds in skimpy swimwear and my sister in ...aw in a top with no bra I could see the outline of her tits and as far as could tell no panties either.The BBQ was going well and the sun was getting hotter by the second I took my shirt off as I heard a gasp from the 3 girls, Penny shouted out go on flex those pecks I laughed as I did as she asked, I had been working out allot and was totally. "Fuck me," was the general comment.I loved it all, loved them staring at me, their comments about my big tits.It was only a small room, much smaller than mine so after a bit... "Do you mind?" said one guy, as he sat down on the bed next to me.I looked up at him and he was quite cute."Trev says you're only fifteen, is that right?" he whispered to me."Yeah," I giggled and I could feel my tits wobbling about catching everybody's eyes."You've got big tits for someone that young," he said boldly.I. His hands forcefully rubbed her back, exploring the cheeks of her ass at times. Her hands combing through his hair, pulling his neck closer, reaching down to cup his balls at times.Sounds came from the door, he quickly sensed it was Randi. He knew she'd heard the sounds, but simply watched excitedly from the door.He rolled Kim to her back, lifting her legs at the knees up. Spreading them apart, he began to enter her certainly wet opening. She was loose, he felt. There was plenty of room in her. He hesitated, but then sat. I went to him, got on my knees and started touching his legs. He startled and asked what I was doing, and I said that it was his birthday present. He was clearly surprised, but didn't do anything to stop me. I felt his cock through the cloth, and it was already hard. So I opened his pants, took it out and began to lick it. Soon I was sucking it all over, and he seemed to really like it. I was loving it, and wanted to tell you. So I pushed him back to lay on the bed.
