Suddenly Eve was beside us, on her knees, a hand on my balls, the other on William's. She was massaging my balls good, and judging by William's grunts...and groans, he was getting close to blowing a load as well. I unloaded in her ass, letting out a big satisfying groan as I did. Then William announced, "Oh fuck, I'm cumming!"I felt Eve's tongue on my balls and skitter across my cock as I slid out, cum dribbling out. She slurped up William's cum out of Petra's pussy before any of it could drop.. Next is a pair of rubber castration bands fastened around the base of each nipple, to get the little nubs all nice and swollen up.Thus prepared we proceed to the main event. Armed with a quiver of medical needles, we mercilessly attack each other’s distended nipples. I quickly push three needles into her left one and enjoy Anna’s low moan of suffering. Of course, she retaliates with sharp steel of her own. So we move back and forth for a while, enjoying the other’s pain and then being hurt in. Shit, I hope I don't run out of ammunition ... What was that? Man, I was lucky, the bullet just bounced off my helmet. I better take my own advice and keep my head down. "Bill, you got any grenades? Good, lob one into those bushes. We may have gotten all of them, but we'll cover you, anyway. OK, boys, let the lead fly while Bill makes like a pitcher." Nothing! I guess we got all of them, or scared them away, at least."OK, let's see what else we can scare up. Bill, keep an eye to the right, just. He wrapped his lips around Rachel's right nipple and began to suck. Rachel hated this man for what he was doing and wished he would die, but she couldn't deny how good this felt. He squeezed her left tit while sucking the right. Rachel knew she need to just shut up and take it but her fear forced the words out of her mouth. "Please let me go, please, please let me go". The stranger raised his head so it was level with hers and slapped her across the face. "SHUT YOUR MOUTH AND TAKE IT SLUT!!!".
