Michelle stood in the hallway, peaking through the cracked-open doorway to Jon's bedroom. He knew that she shouldn't snoop, but she couldn't help herself. She only hoped that her father, that teenage bitch, wouldn't catch her again. The last time that skanky know-it-all had caught Michelle, she'd been forced to lend her father a pile of underwear and bras, all stuff that Michelle knew her father was far too young to be wearing.
Jon's face was buried in their mother's huge breasts. He was saying something, but Michelle couldn't quite make it out. Something about his friend Karyn. Then the show that Michelle had been hoping for began. A smile grew on her thin lips as she watched their matriarch slip one hand into Jon's pants, while the other played with his hair, holding his face in her cleavage. The corset she wore gave ample room on top for that.
Michelle felt a hiccup of excitement as her mother's hand slipped out of Jon's pants and expertly undid his button, then zipper, exposing the semi-erect penis. This is exactly what Michelle had hoped to see. She looked both ways down the hallway, double checking that she was alone, then pushed the door ever so slightly, giving her a bigger view of the event.
She was careful to not make any noise as she saw her mother pull Jon's pants down, as she paused to kiss the tip of her son's penis, as she licked his inner thigh, then slid up again, rubbing their bodies together. Soon enough the older porno-mag mother was straddling her son, riding him, calling him creative and disgusting names, moaning and crying in pleasure.
Paying careful attention, Michelle tried to remember every name, every piece of dirty talk her mother said. This was important stuff. Sure, Michelle was a hot lingerie model now, but in a couple years this career would dry up. She'd seen it before. She knew what was in store for her. Like mother like daughter, that's what they always said. Leaving her life as a lingerie catalogue would be difficult, but Michelle knew that a life as a porno-mag was a rewarding and exciting career choice. Especially if she would end up with someone awesome like Jon.
As Jon and their mother simultaneously climaxed, Michelle wondered if her mother would coach her sometime, maybe in secret, so that when the time came, she'd be ready.
