When Richard Davidge woke up a number of hours later, there was an
incredible
feeling around his penis, which was hard again. He looked down to see his sister struggling to get his girth into her mouth, little more than the head really, as his mother quietly gave her instructions.
"Just relax your jaw...don't forget about your tongue...you can to be very liberal with your saliva..."
Rick stifled a moan as he saw, felt and heard what was going on, what his sister, Kristin, was doing to his cock while his mother, Janice, coached her. Kristin's technique was inexperienced and inconsistent, but the incestuous sight of his naked sister and mother more than made up for the amateurish fellatio.
He looked forward to how this "lesson" would proceed. He had already climaxed so many times in the previous 12 hours, so he was very relaxed and content to let the "lesson" progress at its own pace.
For several minutes, while she awkwardly sucked her brother's cock, Kristin had her eyes closed, tightly at times, as she occasionally winced in an effort to control her gag reflex. Her mother, Janice, was looking directly at Kristin's performance, continuing to verbally coach her while gently holding her long soft hair behind her head. When Rick let out an involuntary groan of pleasure, both women glanced up at his face. He was grinning from ear to ear. His mother smiled lovingly, and Kristin winked at him, her lips still stretched around his shaft.
For a short while, Kristin got into a surprisingly good rhythm. Once she'd figured out how to keep from gagging she managed to get about half of her brother's cock in her mouth. She bobbed her head up and down, using her mouth as a vagina, while her tongue danced around inside. With her mother's encouragement she also began sliding her hands up and down the lower part of where her brother's saliva-slicked dick was exposed.
Rick was in heaven, and he was surprised to feel the very early stirrings of a slow-building orgasm. He really hoped he'd be able to cum in his sister's mouth. But suddenly Kristin's rhythm grew erratic, and she lifted her head up, removing him from her mouth.
"I'mโI'm sorry, Ricky," she mumbled, reaching up and massaging her cheeks with one hand, keeping the other around her Rick's throbbing manhood. "My jaw is getting sore."
Both Rick and his mother told her not to worry; she did great for her first real attempt at it.
"For your first time," Janice said, "you just happen to have a..." She trailed off, glanced at her son, blushed profusely, then turned back to her daughter, "You just happen to have a very large, er,
specimen
to experiment on."
This made Rick blush as well, but it also caused his cock to twitch in Kristin's light grasp, causing her in turn to giggle and give him a squeeze.
"I'm afraid I teased him into a frenzy," she said, "and I'm sorry again, but my pussy is just a little too sore to go again just yet..."
She had started to say this directly to her brother, but at the end of that statement, she aimed her brother's long hard erection toward their mother. Janice smiled and nodded.
"I'll take it from here," she said cheerfully. "Watch and learn."
Rick's sister released her grip on her brother's shaft only when their mother reached over to take it in her own hand. She pushed her hair out of the way and scooched over so that she could easily take over the blow job while giving both of her children an excellent view. She licked her lips, let some fresh saliva drool directly onto the head of her son's dick, then took him into her mouth.
Compared to Kristin's sweet but simplistic style of sucking cock, Richard's mom was a practiced pro, and, while she couldn't quite deep-throat him, she managed to get several more inches of his dick into her mouth. Rick yelped like a virgin teenager at how fucking fantastic it felt.
"Jesus, Mom," he blurted, looking at her in amazement. "That feels...
so good
!"
It was Janice's turn to give him a wink, adding a moan of pleasure herself. Back when she was a younger single woman on the dating circuit, and even in the early years of her marriage, she'd grown to particularly enjoy going down on a guy. She loved how she could control just how much or how little she could tease a man, and she couldn't help but also enjoy the classic submissive element of it. If she was with a guy she really liked, was really into, she could even achieve orgasm herself without any other stimulation other than what her mouth was doing to her man's cock.
She of course loved her son very much, and now being able to engage with him sexually like this made her desire to bring him off with her mouth all the more compelling. Although she hadn't had a lover in quite some time before suddenly starting all this up with her kids, Janice knew she still had oral talents.
Kristin was taking notice, too. "Wow, Mom," she said. "You are
amazing
at this." She glanced up at her brother and they exchanged a look of lust and astonishment at what their mother was doing to him. Kristin smiled and said, "Ricky is practically drooling. You're going to make him cum, Mom."
Janice lifted her head up just long enough to say, "That's the goal!" She went right back to sucking, and her daughter watched and her son writhed in ecstasy, Janice actually felt her own pussy begin twitching and clenching in a desire to have her own orgasm.
Rick had started the morning thinking he could almost indefinitely endure having his cock sucked, but that had been with Kristin. His Mom was bringing her A-game, and soon enough he felt that slight tingling feeling begin. He moaned in pleasure and placed a hand on the back of his mother's head, enjoying the sight of her bobbing up and down, her talented hands twisting around his saliva-soaked shaft when it became exposed. She also started hefting and massaging his balls, and this is what started him down the path of no-return.
"Oh, Momโoh,
Mom
