Part 2
A quick note: My stories aren't for everyone. If you don't like very petite women with really huge breasts, mother-son incest (or the use of the word "mommy" in a sexual context), totally unrealistic scenarios, or extended foreplay, they might not be for you. If you like those things, great! Vote and leave a comment if you want. If you don't like them -- and I can't stress this enough -- go elsewhere. There's something for everyone on this site. Thanks.

"Becky, please get me a towel," the mother said, her body still vibrating with the pleasure of the taboo experience she had just embarked on. She dismounted her son and sat next to him on his bed, completely naked except for her choker, instinctively running her fingers up and down his smooth chest. The teen girl said "Yes, Mommy!" and ran off, excited to help, her huge breasts bouncing about. She soon returned and handed the towel to her wildly voluptuous mother, smiling bashfully at her brother before her gaze turned to his penis -- which, amazingly, was still rock-hard.
As the mother wiped the immense quantity of her son's cum off her body, Jennifer, the older sister, said, "I guess this is the solution to Brian's incessant jerking off?"
Brian blushed. But he had to admit, he wanted to masturbate in front of his mother and sisters. Again.
"Well, yes, I spoke to a doctor and this is the treatment she recommended," the busty mother said, wiping the final remnants of her son's spunk off her tits, making them jiggle and shake in a way that made Brian's desire to jerk off even more intense.
"Well, I should start helping out, too," Jennifer said.
"Hm. That might not be a bad idea," the mother said. "I have a feeling I'd be pretty worn out going solo. But I've told Brian, we're not going to make love. He can play with body and I can play with his, if that's what helps him... get there. But that's it. He cannot put his penis inside of me."
Jennifer walked slowly to the bed, her toned but curvy body swaying. "What about..." She reached down and began to gently caress her brother's throbbing cock. He groaned, and he stared at his sister's voluptuous figure -- particularly her very large breasts. They weren't nearly as big as his mother's, but Jennifer's body was more classically proportioned: a tight, fit figure -- she was in excellent shape, and had played on multiple teams when she was in high school -- but quite busty. And her top was almost comically tight. Her breasts thrust out, straining her shirt, leaving a significant gap where it hovered above her toned stomach.
"... What about, you know, your mouth?"
The mother signed. "Yes, the doctor said that might be necessary. I must say, he's so thick that I might have some trouble."
"Nah," the gorgeous sister said, eyeing her brother's impressive cock. "I can help if you want." She kneeled down next to the bed, and, without warning, grabbed it and began to lick, bottom to top, occasionally adding a sloppy kiss to its head.
"My goodness!" the mother said.
Between licks, the sister said, "Hey, you said I could help."
"I said maybe, young lady."
"Look, he obviously needs help. I'm just being a good sister." She then plunged her mouth over the head of his pulsing cock, taking a few inches, and began to suck, as her hand moved up and down and back and forth along the shaft. She withdrew her mouth with a "pop!" sound. "Do you want him to suffer?"
"Of course not, but --"
"Then let me help." She plunged the cock back into her mouth and began to suck, harder and deeper this time. Soon she had most of his cock in her mouth.
Brian couldn't believe what was happening mere inches from his face. His gaze darted from the incredible sight of his super-hot sister ravenously sucking his prick and his aghast -- but clearly turned on -- mother, who looked at him with a mix of confusion, compassion and horniness. He also noticed that his twin sister, Becky, was sitting on the floor, cross-legged, staring at the amazing show in front of her. She had snuck her hand into her pajama pants and was, Brian assumed, slowly rubbing her clit.
"I... suppose that makes sense," the mother said hesitantly. "Brian, does it feel good to have your sister suck on your big penis?"
The son could only squeak out a "yes, ma'am." His sister's mouth was heavenly. Again, with a "pop!" sound, Jennifer pulled her ravenous mouth off her brother's cock. She reached down and put her hands at the bottom of her t-shirt.
"My tits aren't as big as Mommy's -- or Becky's," she said, shooting her bashful younger sister a smile, "but this would be more fun if I was topless, right?"
With that, she pulled the skin-tight t-shirt over her head, revealing a lacy white bra. She quickly removed that too and Brian marveled at how little the bra was doing to support her tits; they were so firm and forward-projecting, it was clear she didn't even need to wear a bra.
'You have very beautiful breasts, sweetheart," the mother said. His now-topless older sister returned to his cock. Grabbing it and giving it a few licks, she said, "Thanks, I know -- though I've always been jealous of your size, to be honest. Anyway... c'mon Mom. If I can do it, you can do it."
The mother was hesitant. "I did promise to help you when you needed it," she said, reaching down to lightly stroke his penis. Feeling bold, Brian reached up and squeezed one of her massive tits, then tweaked her hardened nipple. She groaned in pleasure. "Please, Mommy?" he begged.
"C'mon, I'll show you," Jennifer said, as she pushed her mother's head toward her son's penis. She leaned down as well, and started licking his penis. His mother followed, reluctantly at first, but soon she and her daughter were rubbing their lips up and down his cock, interspersing with kisses, but then in sync, up and down. It almost felt to Brian like he was fucking -- full coverage of his thick penis. It felt amazing.
Becky stared wide-eyed, stunned. But she also masturbated more vigorously. She had always had a crush on her twin brother, and seeing him being serviced by their petite, completely naked, wildly voluptuous mother, and their taller, sexy, toned sister was overwhelming. Brian looked over at her. Her face was flushed and she was groping a huge breast through her pajamas with one hand, the other down her pants, working her clit. She bit her lip and her breathing quickened; she was clearly getting closer to orgasm.
Meanwhile, Jennifer withdrew from her brother's cock, got up and removed the remainder of her clothing: her tight jeans and little white panties. She sat down next to her brother -- their mother still licking and caressing his cock with her tongue -- and kissed him deeply. She then whispered in his ear: "Do you want Mommy to suck your cock, Brian."
"Yes," he squeaked.
