This work is inspired by the stories 'BTSC' and 'Room 209' by the author 'klrxo'. Also thrown in are elements of the many mom/son stories I've read over the last 25 or so years.
It started out as my own spin on the above stories, but soon took on a life of its own. Too big for one single story, so split over a series.
It should be obvious, but this story isn't a stand-alone. Please read the other parts before this one.
Part 11 continues the adventures of Mark, Mandy and other characters. Dan steadily becomes more open-minded, while Ryan is brought deeper into the SAMBA fold.

Chrissy was still rubbing her clit furiously when her son yanked his dick rapidly out from the grip of her anus. As usually happened, her mouth flew open at the abrupt withdrawal, which always felt like the teen was sucking her bowels out along with his cock.
Steve sank back, sitting on his heels, his breath coming and going in a ragged gasp. His thick penis continued to tick up as the intensity of his climax began to fade. A final drop of semen oozed from his piss-hole and dripped onto the sheet below.
Hearing a whimper from his mom, Steve raised his exhausted head in time to see her tremble and shake. The tiny blonde mom had been crouched low on all fours with her knees wide apart; her hips tilted upwards in an early morning gift to her son. Steve was rewarded with the sight of his mom's pink ring winking at him.
"Oh, baby! My sweetie! Your hard cock was so good in my ass!" Chrissy sobbed and shuddered. Her fingers now circled slowly, her wet pussy lips slipping and sliding smoothly.
Both mother and son sighed deeply and were silent for a minute while recovering from their exertions. Their heads swam with the pleasure of their bonding session. The air of the room was filled with the scent of ass and sex.
Chrissy drew her widespread knees together and slumped her shoulders forward on the mattress, head to one side, her eyes half closed. Steve's erection slowly deflated, but the ruby red head of his cock that had enjoyed such sweet friction in his mother's clutching rectum remained exposed and swollen.
Steve raised his hands and pulled his mom's firm buns hard apart.
"Wow! Just...wow!" Steve croaked in amazement.
"What is it, sweetie?" asked weakly, her blonde curls an untidy, tumbled mass around her head. Stray strands clung to the beads of sweat on her face.
"You're still gaping, Mom!" Steve replied. "I love it when you do that! Fuck, it looks good!"
The teen's wide eyes were fixed on the glistening, wet orifice between his mom's rear cheeks. It remained hanging open, about half an inch, significantly smaller than the diameter he'd wedged her back door open.
"I'm not doing anything to make it do that, Stevie. It's always super relaxed after you've fucked it. My little asshole is used to your regular morning visits, I guess."
Chrissy was surprised that her son hadn't left the bed and hurried to the shower. But whatever the reason, she was pleased with his presence and exchange of a few words, even if it was only to talk about her gape.
"Mrs Wheeler's asshole did the same after I fucked her yesterday morning," Steve revealed. "And just like you, she came hard, Mom!"
Chrissy heard the pride in her boy's voice and smiled as she realized why he had hung around. Naturally, a night in a different bed with another woman had given the teen a lot to think about.
"Mrs Wheeler is lucky to have a sensitive asshole that can make her come without any clit play. Did you know that?"
"Yeah, yeah. I know that," Steve replied, releasing his mom's butt cheeks now that her anus was finally closing up.
"That's why you have to take your time with her, or any mom, really," said Chrissy as she stretched out flat on the bed. "Even though we moms do it all for you, it's much better when we can get off with you, sweetie. Doesn't it feel good to you when we come together?"
"Yeah, I guess."
"Mrs Wheeler's focus is on Mark, of course, but that doesn't mean she's not grateful for how you made her feel. I know she likes you a lot, and you can be sure she'll remember that anal orgasm for a long time."
Steve didn't reply, but Chrissy could sense that her son was busy processing the weekend's experience.
"Mark is the only other person who can make Mrs Wheeler feel that way, you know? Her husband can't, nor anyone else. I know exactly what it's like. It's a different experience, bonding with a son or a friend's son. After years of marriage, sharing your body with a young man new to the world of sex and seeing the difference it can make is life-changing."
"She...she wanted to talk to me - said she wanted to get to know me," Steve shared.
"Of course, baby! She wanted the emotional connection and the sense of accomplishing something wonderful together. That's the SAMBA way, sweetie! We, moms, are made a little different - while you boys are thinking about how warm, snug and tight our asses are, we're concentrating on you having a fulfilling and happy time. The whole vibe is better when we know and understand you better."
"But she had so many questions, Mom. It was difficult to think with her tanned body and boobs in my face," Steve explained.
"It wouldn't be any fun if a mom weren't distracting, would it?" Chrissy giggled. "Wasn't it all worth the effort, Stevie? Because I think you two made a real connection. In the end, you took your time and gave her an amazing orgasm, and now you can feel proud of that."
"I was whacked out by then, Mom. But I couldn't help it, and I had to have that ass again," said Steve. Then, a sudden thought occurred to him. "Has Mrs Wheeler been talking about our night together?"
"Only to say she thought it was a great success, and you managed to come with her many times! You're lucky to spend time with a beautiful mom like Mrs Wheeler, who takes her SAMBA duties very seriously."
"She's the hottest - other than you, Mom!" Steve added hastily. "I'd like to do a swap again sometime."
"We'll see, Stevie. I can see that it's benefitted you and made you more thoughtful this time," said Chrissy. She didn't like to mention in front of her son that she also looked forward to more intense mom-teen sex with young Mark. The idea of another night mothering him made her heart flutter. "Speaking of being thoughtful, Mrs Wheeler told me that she kept all your cum plugged inside for hours. That's sweet of her, huh?"
"She did? Wow, that's awesome! I shot three loads up there, Mom!" Steve declared proudly.
"I know, sweetie," smiled Chrissy. "And it meant a lot to her, too, I'm sure. Listen, I'm glad we had that talk, but you better get moving, or you'll be late for school."
"Shit, you're right," replied Steve as he scrambled to get off the bed. "Hey, can you give me a ride to school, Mom?"
Chrissy sighed. She knew she'd probably end up leaking boy cum into her panties as she had done before when driving straight after anal sex in the morning. On the other hand, she was so pleased with the promising changes hinted at this morning that she couldn't refuse.
"Okay, you better hop in that shower quickly while I get dressed."
Chrissy sat up in bed and watched her son scurry from the room, his swinging cock still glistening with lube. She smiled after him, pleased that how a night of passion with another loving mother had hopefully planted the seeds of change.

After Mark had left for school, Mandy headed straight to the bathroom to sit and let her son's sperm slowly drain from her anus. She planned to visit the gym this morning and didn't want to risk a cum-fart while she was working out.
She hadn't yet caught up on her sleep after the weekend, and part of her dreaded the thought of the exertion, though she knew from experience that she'd feel better after doing the exercise. There was also another mother of similar age she'd met there whom she'd struck up a friendship with. The divorced, single mother had a troubled son, and Mandy had been waiting for the right moment to refer her to SAMBA.
