After another minute or so I felt it begin. I looked at Emily and nodded up and down. She in turn, somehow made her pussy contract tightly around my c...ck and said, ‘Do it‘.Like a trained circus pony I responded instantly to her command. My prick swelled and I began to cum. Emily felt it and let whatever concentration she had been using to hold back go as she too began to cum. It was amazing.I slammed upward trying to get my entire being into my sister while she let her pussy squeeze my cock. I opened the package of a g**** flavored condom and he took it from me and tried to put it on. He was taking too long and my urges were uncontrollable at this point. I took charge, tried to slip the condom down to the base of his penis, and then shoved his dick in my mouth, in all of what seemed to be one breath. I was finally getting what I wanted, him fucking my mouth. He grabbed the back of my head and tried to make me deep throat him. To be an asshole I told him I didn't want him touching. I had my rifle up as a ripping sound shredded the bushes and rounds cracked over us. The Charger was already lifting off and I heard rounds hitting it.I shifted, aimed and fired and the machinegun went quiet. I saw another enemy soldier stand with a strange rifle or machinegun and shot him in the chest, "alpha move across!"I could hear the first platoon yelling and shouting and men were screaming. The lieutenant yelled and I saw the other squads rushing. We kept shifting and firing and alpha. "Why wouldn't I?" Kayla replies. "Had a good long chat with Sarah andJenny too, which helped a lot. And they ARE my friends too, youknow?" Yeah," I say with a happy chuckle. "More than just friends, butsisters, real sisters, you know?" Yeah," Kayla says with a happy sigh, before frowning. "...Does thatmean we're guilty of incest?" No," I say bluntly, prompting giggles from both myself and mygirlfriend as we head to the airport.The flight to Las Vegas is just as swish as the flight from London.
