Again. And again

"Again," John yelled.

Mom resumed her previous rhythm, and after a few solid strokes drove into him again. He timed a solid burst again, and again it sprayed out of her mouth.

John looked at his mother on the monitor, her face a disgusting wet combination of spit and piss. Piss was dripping off her nipples. She looked like a cheap slut, and her she was banging har face into his crotch and begging for his piss...

"Fuck, do it again slut, fucking puke on my piss you whore"

Heather drove onto his cock once more, and having learned from the last two attempts she has a better angle to point his cock straight back. She barely heard what he said, so was so focused on what she wad doing. She felt the piss burst out and hit the back of her throat, instantly triggering a gag reflex. She struggled to contain herself, and barely managed to get most of the puke into the narrow tube. But there it was, mostly filled.

She coughed and yelled " that worked", and then decided not to lose stride and went immediately back to his cock.

If John thought his mom was a mess before, she was something amazing now. One moment her stomach is emptying itself, and the next she is back on his cock looking for more.

John knew he didn't have much piss left, so the next time she drove into him he let go with everything he had. Again she jumped off and puked into the tube, overflowing it and lighting up its light.

"Thank goodness it's done. Just one left, and it should be easy "

"Get back on there and finish me off slut"
