Emily and Carla sat on the front porch sipping iced tea and watching Billy mow the lawn. Watching Billy work up a sweat was quickly becoming a favorite pastime of the two women. At thirty seven, Emily has had a marked increase in her sex drive. She was basically out of control, and Billy was only too happy to administer to her needs. Without even realizing it, Emily had slipped a hand down her shorts and was pressing two of her fingers against her clit as she watched her stepson work.
Carla glanced down and saw what her mother was up to. She giggled and rolled her eyes.
"Mom, you really are unbelievable," she said.
"What?"
Carla raised her eyebrow and made a show of looking down at what Emily was doing with her hand.
"Oh. I didn't even realize I was doing that," giggled Emily.
"He really has turned you into a complete slut, hasn't he mom?"
Emily smiled at her daughter. "Listen to the pot calling the kettle black. You were so loud begging to be fucked last night that the neighbors must have called the police."
"That was a problem because we woke you?"
"No honey. That was a problem because you didn't invite me to join you," admonished Emily.
In the months since Billy had first fucked Emily, the relationships between the three of them had morphed completely. Both of the women had fallen in love with Billy, and he with them. The women loved each other as well. Emily no longer thought of Billy as a boy. She saw him as a man, and he had taken over the household. No major decisions were made without her first consulting with Billy. They engaged in some light bondage and discipline, and it thrilled Emily beyond words to have her stepson spank her ass with his bare hand. Billy ruled the roost, and the two women could not be more satisfied with that.
The more Emily watched Billy work as she pressed her fingers against her clit, the needier she became. Watching her brother was having a similar effect on Carla, and she started to rub her own pussy through her shorts. The women were cut short when Billy stopped the mower and walked towards the porch.
"It's hot out here. Would one of you beautiful ladies get me a glass of iced tea," asked Billy.
Carla got out of her seat and walked toward the door. "Sure little brother," she said as she glanced over her shoulder at him. She wiggled her ass flirtatiously as she walked into the house.
Billy sat on the arm of Emily's chair as he waited for Carla.
"You are just a joy to watch," Emily said hoarsely. She reached her face up to his neck and ran her tongue from his collar bone to his ear, tasting his salty sweat and lightly biting his earlobe. "I was touching myself while I watched you, and now I'm all wet and throbbing. You want to take a break, honey?"
Billy's reply was to grab Emily by the hair and tilt her head back, kissing her deeply. By the time Carla came out with Billy's drink, Emily was topless and sitting on Billy's lap.
"I can't leave you two alone for a second, can I," said Carla as she sat down and watched them kiss and fondle each other.
Emily was purring and grinding herself against the bulge in Billy's shorts. She wanted more, so she got up and started for the door.
"Time to go inside for a while."
Billy and Carla grabbed each other's hand and followed Emily into the house. The two women worked together to undo Billy's shorts and pull them down and off. He stood there naked except for his sneakers. Emily was on her knees with his cock in her mouth, and Carla stood beside him kissing him and running her hands all over his body. After a few minutes, the women switched positions. Emily was kissing Billy with extra fervor.
"What's gotten into you today, mom?"
"I think I'm going to get my period. That always makes me horny as hell. God, I need your cock inside me, Billy," said Emily. "I need you to fuck my brains out. I've had enough foreplay."
Carla pulled Billy's cock from her mouth and looked up at her mother with a raised eyebrow. "Wow mom. You are unbelievable today. It's like your cunt is on fire," she teased.
