"Oh, fuck me hard!" she moaned, already delirious with pleasure. "Shove your finger in my ass! Do it, quick!"Reaching under her, Mark searched with hi... middle finger for her anus. When he found the tiny puckered opening, he lubricated his finger with the fluids that had trickled out around his hard-driving cock and began to probe at the cringing little ass-hole. He pushed hard, feeling it give a little, and then suddenly the tight elastic ring fell before his attack and his finger slid in to. That aspect worried her. Everything here was ... better. But, was it really? Krissy had seen a movie where people thought they were eating this incredible food, but in reality it was rotting, maggot filled slop. Was that the case here? Was this an illusion?Krissy didn't like illusions. Or delusions. They hid evil. She had deluded herself that her family was happy. Stable. If she had seen the truth before, accepted it early enough, maybe...Well, she'd keep her wits about her here. Not trust. "She reached up and gathered her hair in her near hand. Her breasts rose again."Move a little so it's an exact profile. Good." She licked the fingers of her other hand, tweaked her nipples. They rose sharply. She looked at the camera."Take it."Alex took it.Heather went to the computer again. "What graphics program do you use?" Mostly Photoshop." Can you show me what you plan to do next?" She grabbed an extra chair and sat down next to the operator's seat.Heather worked beside him for the next. Her wet lips bobbed up and down, sliding along my thick pink veiny pole over and over as she eagerly took more and more of my length into her mouth, and the way she seemed to be happily sucking away on my cock, it was fairly clear she wasn't going to stop until I had given her, her morning special yogurt!After just a few minutes my breath was heavy, and my moaning fairly constant as my hot teen stepsister rapidly sucked on my hard cock and any second now I was probably going to blow my load.
