"You won't lie to me again, Carla. This whole session's going to change that."

"Agghghghhhhh!"

With a quick move, Mike turned on the faucet of the barrel. Carla stiffened, her spine straightening while her asscheeks jiggled. She felt the cold stinging splash of the beer spatter into her shitter. Her body jerked, her asscheeks dancing and bobbing up and down. To her concern, Carla felt the dildo starting to slide into her pussy from her wild moves. Struggling for concentration, the woman tried to keep her body still. But the coursing beer was so cold and splashing all about her asshole, and it was difficult for her to remain impassive. In a moment, she felt Mike let go of her completely, her own body betraying her and forcing her pussy down onto the steel dildo.

"That's it, Carla. You're going to fuck yourself real good on that thing. Doesn't it feel good rodding into your cunt?"

"Uhhhhhh!"

Carla shut her eyes, letting her head fall back as more hard, cold inches from the thing speared into her cunt. In a moment she knew a little more than half of that thing had penetrated her body, squeezing past the swollen tissues of her pussy, pushing down deep into her cunt.

"Now, we're going to add something that'll make you feel a little more excited… if that's possible."

Carla opened her eyes, watching as Mike took the translucent tube and unraveled it. He was moving away from the small circle of yellow light illuminating the barrel and stool. Carla narrowed her eyes, trying to peer into the darkness surrounding Mike. She heard him fumbling around with something, still holding onto that tube. There was a whirring sound, quickly followed by the chugging of a small engine. Mike reappeared, wiping his hands against one another. At the same time, Carla felt something very odd in her cunt – a kind of strange movement of sorts. Air! Of course! Those tiny holes at the end of the dildo were letting out air in sharp, tiny pulses, the pressure provided by a compressor and fed into her cunt by the tube.
