After a long morning of getting fucked by Janette in the ass twice and Jane once, and both of them covering his face with what seemed like a gallon of their seed, things got to a normal state for the rest of the day.
Normal, in Billy's case that is. Once Jane came back to his room a few hours after their fuckfest, and wanted him to perform his special ball-trick. He dutifully did and was rewarded by a mouthful of her cum a few minutes later. And he would never tell his mom or Janette, but Jane's spunk tasted best. It was almost as sweet as pineapple ice cream.
Another hour later, Janette walked into his room, naked, laying down spread-eagle on the bed and just pointed to her dick. Again, little Billy did what he knew was best at: Satisfying the futa women of his family, this time by riding his oldest sisters cock with his still sore ass.
The evening rolled around and with it, his mother came home. The first way, like always, was to Billies room, where she always needed to get the stress -- and cum -- of the day out of her system.
She opened the door and the first thing Betty noticed, was the almost deafening scream "Swallow it all!" from her youngest daughter. She saw her sons face pressed hard against the base of Jane's cock. She moaned loudly and clearly enjoyed her orgasm.
After Jane came down from her orgasmic high, she noticed her mother. "Hi, mom. Home already?"
"Yeah," Betty said. "A good bit of work today, though. Mind if I have some play-time with Billy?"
Jane shook her head. Even if she would have wanted to get another load out, her mother had made it very clear on multiple occasions that she had first dips on her son -- always.
Billy meanwhile got up from the floor and padded over to his mother. "Hi, mom," he said and hugged her.
Betty wasted no time and pushed her tongue down her son's throat. Meanwhile, she dry-humped him, her aching cock grinding against his bare crotch area, the two -- albeit very different sized -- dicks just separated by his moms jeans.
She broke the kiss with a loud wet sound. "Fuck, I need to cum!" she exclaimed, tugging down her pants in a matter of seconds. Her enormous cock sprang free and slapped against the stomach of her son.
"Honey, on your knees and open wide," she demanded. Billy didn't need a second invitation and got down in a heartbeat. As soon as he was at eye-level (or rather mout-level) with his moms big girl-cock, she wasted no time. Moaning loudly, she inserted the humongous piece of flesh down his throat.
Billy pushed against his moms hips in an effort to slow her down a bit. Although he had done this many times by now, the speed she often used with him still made it a though endeavor to take her all-in.
"Wow," Jane commented from the sidelines. She was slowly rubbing her own cock, which was stiffening slowly but surely. "This looks so hot."
Betty moaned out loud as her son took another inch down his gullet. "Fuck, yes! And it feels hot too, his mouth that is." She giggled and started a few slow thrusts, in and out, in and out.
