It took the two of them a moment for their senses to return. Erika wobbled on the toilet, and her mother had sunk to her knees in front of her. It took her mother another moment to turn around and look at Erika. "E..Erika, what did that?" She holds up the spray bottle. "This. I found it on the way home, and when I sprayed my butt and... it feels so good mom!" Her mother turns around fully and hugs Erika, still sitting on the toilet. "Oh I know baby, it was amazing!" Her mother pulls back from the hug, looks Erika in the face and then kisses her deeply.
Erika was surprised but went along with the kiss, her eyes closing as her and her mother made out. Eventually they broke away. "I have an idea Erika.." Her mom stood up, and quickly stripped. Her large breasts hung free - she even fondled one as they came out - and her pants and panties were soaked and full of shit. She helped Erika out of her clothes as well, and then into their bathtub. Her mother laid back in the tub. "Lay on top of momma." She says. Both of them felt the rumbles starting again. Erika laid down, their chests mashing together, and they started to kiss again. As they did, it happened again. Their kisses became shared moans as they began to relieve themselves again, the bathtub starting to fill up with their filth.
