This is a direct sequel to "Two Horny Moms, Two Horny Sons" which you can find here on Literotica. It's by daniellesadvisor who passed away a few years ago. I've had the okay from his friend to continue it and, like the original, it's going to be low on plot and more about the sex. Unlike the original, I'm going to break it up into individual chapters. Everyone involved is 18 or over, by the way.

Three Horny Moms, Four Horny Sons, One Horny Daughter
Chapter 7
"Is that you, Rob?" Tiffany called as she heard the front door open and then close.
"Sure is," Rob called back, following the sound of his mother's voice and heading to the kitchen. "Wow, mom," he said, standing in the doorway. "You look fantastic."
Tiffany stood at the counter, pouring some OJ into two glasses. Her hair was tied back into a ponytail and she wore a tiny white bikini, the small triangles barely covering her nipples, the thong bottoms disappearing between her bare, perfect ass cheeks. Looking at her in profile, Rob could see a massive amount of side boob.
"This little thing?" she asked innocently. "I found this in your sister's room and thought I'd borrow it." She reached for a third glass and poured some juice into it. "Fancy joining me in the hot tub?" she asked, putting all the drinks on a tray and heading out.
"Sure," Rob said, following her, his gaze fixed on her taut ass. "Whose is the third glass?" he asked.
Instead of answering, Tiffany opened the back door and headed out to the garden, carrying the drinks with her, until she reached the hot tub when she put them on the side.
"Hey big brother," Serena said. She sat in the tub, the warm water bubbling around her, splashing over the slopes of her huge tits which were only just encased in a blue bikini that was easily as small as the one their mother was wearing. She raised up and leaned over to get a glass of juice, her firm mounds testing the bikini's straps as they hung down, water trickling off them. "Come to join us?" she asked, sitting back down.
Tiffany climbed up the steps and got into the tub, sitting down next to her daughter, drink in hand, and looked over at Rob.
"Coming in?" she asked him.
"I'll need to go get swimming gear," he said, indicating the house.
"We don't mind you getting in with your underwear on," Tiffany said with a smile.
"There's the problem, mom," Rob said. "The weather's been so hot lately, I've taken to not wearing any. I'm sure you and Serena don't want me getting in to the tub naked, do you?" he asked, a huge grin on his face.
"Hey, we're all grownups here," Serena said. "And if it makes you feel more comfortable, I'm sure me and mom could slip out of our bikinis. After all, they're so small it's not like you're not seeing pretty much everything we've got anyway." His sister cupped her huge tits, the flesh bulging out from her hands.
Rob kicked off his shoes and pulled his T-shirt over his head, revealing his muscular torso. He gripped the waistband of his shorts, his mother and sister staring at him all the while, and pushed them down. His thick, half-hard cock bobbed into view and he grinned proudly as Serena's eyes went wide.
"Wow. You really are my big brother," she said.
With a smug grin, he climbed the steps and slid into the hot tub, sitting on the opposite side to his mother and sister, putting his arms out along the edges.
"So, are you and mom going to lose your bikinis like you said?" he asked.
