When I gagged some of the cum went straight down my throat. I gagged again, again and again. Each gag sent shivers through Jocko’s cock and he repla...ed the expelled cum with new cum.Barbie pushed the dildo deeper. Jocko came again and again and again. Jocko was convulsing cum. The convulsions were matched by Vic and Ange’s simultaneous orgasms from finger-fucking themselves.Jocko’s continued cum convulsions triggered me into grabbing Vic and Ange’s nipples even harder, twisting them even. But deep inside, I wanted it to happen. It didn`t happen everyday but he would surprise me with it anytime he wanted. They found out other ways to tease me and i got through them:No bra at school- Damn I thought I was fine but sometimes when I would think about nothing wear a bra, it aroused me and gets me horny. As my school uniform consists of a white blouse/ shirt, and if I moved the top part of my dress and looked closely, I could see my hard nipples and my areola. Combining both of them-. Jina then had a lot of fun direction the action like Pete had, and when I came, the relief was well worth the effort. I shook like a vibrating machine when I did. The magic flooding my system was mind blowing.After Jina had pulled out of me, she staggered to the bed and flopped on it. “Bloody hell Mikal are you in season?” she asked me.“Oh shit!” I said. “If I’m this bad now what am going to be like when I am?”They looked at me. I turned my bling on so they could see it. To say they were. Not better, nor worse, simply different. They swapped a couple more times during the evening, both men fucking their sisters twice and their wives once each over a three hour period, finally getting home and to their own bed's shortly before one in the morning.That first evening was such a resounding success, and all four were so delighted with it, that they came together the following evening, despite their original decision about never doing it again on army property. This time they started.
