While Jessica sucked the lube that had been Steve off the anal beads that had been Jeff, Patty was busy with the Chronivac again. She grinned wickedly as she pointed it at Jennifer and there was a beep to signal the commands being executed. Jessica shivered, a strange fuzzy feeling washing through her head, though nothing seemed to have changed... until Patty spoke from behind her. "Ok, my lovely slut, lie down on your back on the floor with your mouth open and your tongue stuck out". Without even stopping to think about it, Jennifer did as ordered, following her teenaged mother's orders feeling entirely natural. When she was in position, there was another beep, and she felt her tongue start to grow, until it was six inches long, sticking straight in the air.
Patty grinned and positioned herself over Jessica's face, crouching down until the tip of that long tongue was prodding gently at her tight teen asshole. She rotated her hips a little, getting nice and wet, before she started to press down. A quiet moan escaped her as she felt her asshole start to open up and accept the invader, getting louder as she slowly sank down until she was sat on her new slut's face, her spankable ass covering Jessica's face. She paused for a moment, relishing in the feeling of fullness, before she started to rotate her hips, lifting up and plunging down again, fucking her ass with her former daughter's freakish tongue. "Oh god, your tongue feels so good in my ass!" she cried, as she started to use a hand to play with her clit. It didn't take long before she came, hard, her tight cunt gushing all over Jessica below her. With a sigh, she relaxed and sank down, once again smothering Jessica with her asscheeks.
Patty frowned as she considered what to do next. The frown was soon replaced with a grin, though, as she palyed with the Chronivac some more before using it on Jessica again. Jessica, who had been squirming beneath her as she started to feel the lack of air, went rigid, and then began to shrink... all except her tongue, which got a bit longer, thicker and rounder. Soon Patty was sat on the floor, nothing left of Jessica except a fat eight inch dildo stretching out her tight little ass. She wriggled her hips a few times, revelling in the feeling of fullness as the dildo settled inside her properly, before considering what to do next...
