She then followed what her son said and tilted her head up and opened her mouth wide, like she was trying to taste the falling rain. Only in this case, the rainwater she was about to drink was her own fluids that had been marinating in her butt for a while now and have been waiting for someone to slurp it all off.
"Stick your tongue out, Abi, just in case it drips out of your mouth...I don't want you to spill any of this liquid, since it's a precious commodity that most people would get on their knees and beg to get a single drop." She stuck out her pink tongue, while thinking why people would fight over something as disgusting as her sweat, which only made her already sultry brown face that was flushed all over even more erotic.
Her son then put his cupped hand over her mouth, and while she looked up at him with watery eyes like she was ready to receive his load, he tilted his hand like a beaker and poured the fluids into her mouth.
