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 as my spin on the above stories, but soon took on a life of its own. Too big for one single story, so split into a series.
It should be obvious, but this story isn't a stand-alone. Please read the other parts before this one.
Part 12 continues the adventures of Mark, Mandy and other characters. As all the families become more intertwined, Mandy dreams of motherhood.

Mandy drew her lips slowly up the long shaft of her son's cock, sucking vigorously. When she reached the head, she teased it with rapid flicks of her tongue. Kneeling up, Mark's prick popped from her mouth, a trickle of saliva running down to his balls.
"I thought tonight was another success, didn't you?" said Mandy, looking up at Mark's body from between his legs.
Mark sighed as his pleasure was interrupted, and he recognized the signs that his mother had things on her mind. Often, all he wanted was to lie back and allow his mom to give in to her maternal instincts and take care of his penis while he relaxed, closed his eyes and let his thoughts drift. He had so far enjoyed over twenty minutes of unhurried bliss in their bed while his mom had gently kissed, licked and sucked his cock and balls.
"What's that, Mom?" Mark asked reluctantly. The sooner they moved on, the sooner he could get back to enjoying the attentions of his mom's warm, wet mouth.
"After dinner - the breast play," Mandy explained. "You seemed very comfortable, and your dad could barely take his eyes off us."
"I didn't notice. I was trying the enjoy the show and your boobs."
"Well, you should," Mandy insisted. "This is what you wanted, after all. Of course, he's trying to do the decent thing and not outright stare, but I know your dad. You should be as pleased as I am that he's learning about the beauty of bringing moms and sons together."
"I was thinking about the beauty of your tits in my hands, Mom."
Mandy giggled. "That too. It was nice to have you holding onto them while we watched the TV. It makes me feel very loved, you know. And I could tell that your dick was happy - it got super big trapped under my butt!"
"Thanks for moving, Mom. It was getting unbearable sitting still," said Mark, thinking back to how his mom had gently rotated her round ass in his lap.
"That's okay, honey. It was your dad's suggestion. He knows what it's like for a young man."
She'd also gotten a secret thrill from stimulating her son's penis with her butt while in the presence of her husband. But it was also important to normalize the simple things before moving as a family to more sophisticated activities.
"He did?" Mark was impressed.
"Yep. He's a good dad, you know that."
"Can you at least please play with my balls while we talk, Mom?" Mark pleaded, his stiff cock still throbbing in the air.
"Oh! Sure, I can," said Mandy, reaching for Mark's loose ball sack. She tugged gently with her finger and thumb wrapped around, rolling the sensitive contents with her other hand. Mandy's face became serious as she watched the balls move and enjoyed the feel of them in her hands. "Mark, baby, I'm going to help you empty these tonight, I promise. I want to make you come like only a mom can."
Mark groaned, spreading his legs further. The teen only had sexual experience with mature moms, so he had nothing to compare to, but he didn't doubt the truth of his mother's claim. Only they could provide the mix of hot, curvy bodies, maternal love and, most crucial of all - motivation.
"I still regret it took me so long to start helping you come, Mark. But at least now you are in the family bed with me most nights to make up for that. Offering my body and seeing it being used so enthusiastically has made life fun again for me, too!"
"Ah, Mom! You've got great hands," said Mark, breathing heavily as he writhed.
"And there's even more to come, honey. Your dad is accepting that my boobs belong as much to you as to him now! And someday soon, you'll show him everything you do with me. Imagine him knowing your cock goes deep in my pussy! He has no idea of the excitement ahead for us all."
Mark's cock twitched visibly at the impact of his mother's words. Mandy noticed and smiled. It pleased her as much as her son to confirm the shift in the family dynamics. Her heart thumped in her chest, and she felt an ache between her thighs yearning to be eased.
"Your boobs are mine now, aren't they, Mom?" Mark checked, wanting to hear it said out loud
"And always will be, Mark," Mandy confirmed. She still believed wholeheartedly in marriage, only that it had now evolved into another stage. Dan would be adjusting to a new world where his wife shared her feminine assets with both men she loved. There was no going back, and neither did she want to.
"Dad's gonna see how he has to share all of it! Your mouth, your pussy, your ass!" Mark declared.
"All of it," replied Mandy, looking lustfully at his dick as it stood tall against his firm, young abs. In particular, her eye was drawn to the ruby head, its shape now well-defined as blood surged through it.
"And your big, round butt cheeks! Dad will see me hold them and pull them apart!"
"You can start practising now," said Mandy, forgiving her son for how he'd described her shapely rear. She knew she worked damn hard to maintain a healthy figure. Swiftly, before her son had time to protest which hole he wanted, Mandy mounted her son as he lay on his back. Grabbing his hard cock, she directed it to her hungry cunt.
"Jeez, Mom, you're wet!" cried Mark as he slid inside his mom's vagina in one fluid motion.
