Then I realized what she meant. I dropped one hand to her leg, watching her face to make sure that was what she wanted, then moved it into her crotch....I wasn't thinking at all if this was right or not. Erin had become a girl, not my sister, in my aroused thoughts.Her legs spread as my hand pushed in between them, and I reached her pussy lips to find them swollen. Two fingers slipped between them to find an overly wet cunt. She moaned and stiffened as I slid my fingers up and down her slit from. She loved to see the look of anguished passion on his face as he climaxed. She continued to jack his shaft and suck the cum from his balls until he had no more to give.She knew if she didn't leave it alone his cock wouldn't soften much so she moved back to sit beside him."There now isn't that much better." She grinned at him as the tip of her tongue licked that last bit of cum from the corner of her mouth.Bob sighed as his body started coming down from its high. He released his grip on the. . Two... Three!"I bobbed down into the water up to my chin twice and on three, I pushed off hard. I was just coming back up when she pushed off. She was way too early. Her push interfered with mine and she couldn't extend her legs for a good shove. She went about 2 feet then went splat, right down in the water!"No! You went too soon! You have to wait until I get to the top! Let's try again." I squatted so she could get back up. "Okay, here we go. One... two... Where are you going? I didn't say. He closed his eyes and let the man thrust into his mouth, making him gag occasionally. "Mmmm you fucken love that don't you private? You love that big cock in your fagget mouth!?"A stifled groan of agreement was the only response and the white cock grew big a hard as the black man licked and sucked it. I was so confused by the words the officer used and how he could be doing this with another boy. It felt wrong watching it and I wondered why my Dad was watching such filth. The springs.
