Allowing her lips to part, the cock entered. Her lips closed automatically, and she began to suck.It wasn’t long before she felt hands grab her roug...ly by the hair and pull her down onto the cock. She felt the tip of the cock enter her throat and begin to twitch. While the liquid before was hot, this liquid was warm. And it was gooey.As the cock continued to twitch in her throat, Lisa realized she couldn’t breathe. She began to panic, trying to pull herself free, but the hands held her. "Turn it back on, Sweetheart," Mommy panted, "I need more, uh, punishment." Nope, Grand Dad said half an hour," the boy shrugged as he released the straps and freed Mommy from her perch."Billy, I'm your mother, I said turn it back on!" Thirty minutes, no more no less," Billy switched off the video camera, removed the tape cartridge and dropped it into a padded envelope. "I've got to mail this," he turned and slunked toward the front door."Billy! Please," Kathy begged, "we need more." Don't try. "Most people, though, learn in something smaller, lighter, and simpler. But it's not unheard of to use one of these." Well, I don't expect you to buy me my own..." she giggled."Actually, that's NOT unheard of, little one. Planes like this are pretty much bottomed out and on the way up in value. You buy one, use it for whatever, like getting your license, then you sell it for what you paid, maybe a bit more. But I'm thinking, no, we won't do that." It's all just crazy, when you think about it,. Shit, I swear I can feel the two of you rubbing against each other through the wall of my pussy.”In one contradictory moment, it was both the most depraved and the most erotic thing I’d ever seen. My beautiful wife of thirteen years, mother to our two sweet kids, lying in a bed with two young gangbangers while one of them was deep in her pussy and the other prepared to fuck her ass. The icing on the cake being she was willingly submitting to this and looked like she was about to start enjoying.
