Before you gave any answer to Patricia's proposal, the two of you felt the ground shake slightly and then saw Dolores approaching. She stood before Patricia and crossed her arms while their eyes locked.

"I thought Miri would've been the one to come to get her baby boy back herself" Patricia remarked with a chuckle.

"She means to, but she's still arguing with Sheila" Dolores replied, chuckling as well as she looked back. Those two were still bickering like back in the day. It was undeniable that their friendship was very close and practically a lifelong one, but at certain times they seemed to be siblings and even now, nearing 40 they didn't seem that different from when they were 16 or so.
"But you're right that I do want my baby boy back" Dolores added, giving you a wink and a playful smirk.

"Oh? Does Miri even know you're claiming her child now?" Patricia said with a teasing, smug look.

"Of course! I helped her the most out of everyone else to raise him, I've rightfully earned my title as his second mama" Dolores replied "And just like the first, I'm entitled to some quality time with him"

"Didn't you have him massaging that big bum of yours while putting suntan on you?" Patricia raised an eyebrow as she spoke. She was more observant than she was given credit for and from the beginning, she had noticed how pretty much all the ladies were looking forwards to spending time with you. Your mom's decision to include you in their pool party had unofficially become the highlight of the day though Patricia only learned exactly why far more recently.

"Sunscreen, and yes" Dolores nodded "But I'm not gonna make him do anything like Miriam, I just want to reward him for always being such a great help" She said with a sweeter tone and the look in her face matched, that was the usual one you knew her for.

"I mean, I'm also offering him to rest and relax" Patricia said.
"Asking him to give me a booty rub at his current size might be too much... but I wouldn't mind" She almost purred the last part.

"Then why don't we let him decide?" Dolores replied and looked at you once again. Since she was the person outside of actual family that you were closest to, she was nearly sure that you'd much rather pick her over Patricia but then again, as the woman boasting the largest ass in the world, this was one of the few instances where Dolores herself felt that she was physically outmatched and she suspected that just like your father, you had a natural weakness for such things.

On the other hand, she knew that you weren't a perverted guy or one whose horniness was out of control, in fact, your integrity and self-control were among the reasons why she entrusted you with looking after her daughters to keep them from getting in boys-related troubles. Ironically, she ended up having to protect you from them more than once.

"Hmm... I think I can see where you're going with this" Patricia said.
"Tell you what, you can have him but I want my turn right after yours" And as she spoke, she gently placed you on Dolores' chest and then she began to walk away, heading in the direction of your grandma Xóchitl and aunt Betty, who were cooking something.

Both Dolores and you were caught off-guard but after the initial surprise wore off, you thought about it and well, if you had to choose between Dolores and Patricia you were way more likely to have picked Dolores, and it seems that Patricia herself realized this. Still, you were embarrassed that you were on her chest. You hadn't thought about it much but given her size, Dolores had a pretty massive chest herself, larger than your mom's, who was quite busty and even larger than Jen's, who otherwise had some of the biggest you'd ever seen.

"Well, I'm not gonna complain" Dolores chuckled and picked you up.
"I mean, you would've chosen me anyway, right?" She asked half-jokingly. You timidly nodded, she was right though you still felt somewhat apprehensive about her overall sheer size, even your mom was way too much at this scale and every other lady present could dwarf her with relative ease.
"Then let's go back" Dolores said and you saw the subtle smirk on her face, it was definitely the look of someone who had just won a prize. With that, she walked to where your mom, Sheila and Zuleima were hanging out and just as the former two were about to get up and go talk to Patricia but they stopped in their tracks when they saw Dolores making a triumphant return.

"You guys took too long" Dolores teased them "And Blaise here has chosen to spend some quality time with his second mama" Both Miriam and Sheila looked somewhat dejected upon hearing that but there was also a hint of annoyance in Sheila's eyes while your mom looked... disappointed? Which Dolores caught on as well so it wasn't just you.
"I mean, it's gonna give you time to clear some of that pent-up gas, you two have been going hard on the burritos... I could even hear you from where I was, Miri. Hopefully things will be more calm when you get him back" She then said and began lowering you down while bringing you around her waist, once again reminding you of the overwhelming difference in size between your mom and herself.

But then you noticed something else, Dolores used her free hand to pull the skimpy, flimsy-looking thong she was wearing, basically digging it out of her humongous crack, a colossal chasm that easily put things like the Grand Canyon to shame. Your eyes widened and your heart skipped a couple of beats. Unlike your mom, who had you on the outside of her bikini bottoms, it looked like Dolores was doing to drop you on the inside.

You felt as if your entire body became paralyzed while Dolores lowered you down towards the back of her thong bottoms, wanting to speak up but finding yourself unable to. No matter how much you looked at them, the immense size of her cheeks was simply too much, you weren't even sure if you could withstand that much weight. You sort of zoomed out for a moment and when you came back to your senses, you were already dangling extremely close to the fleshy abyss, feeling the warmth that it gave off, which felt like approaching a sauna.

"You know, Lola, you should've told Blaise you've been gorging on Miriam's burritos too" Sheila then said at pretty much the same exact moment as she let go of you. Your eyes only widened more as you began plummeting down towards the yawning chasm between the humongous fleshy globes.

"Wait, what?!" By the time those words were finally able to escape your mouth it was far too late, and shortly after you found yourself in near complete darkness, surrounded by a very warm, humid atmosphere. The saltiness in the air was also more intense than when you were in your mom's ass, then again Dolores had been sunbathing for longer, that she was sweatier was absolutely a given.

"Oh, hush. Besides, mine aren't as bad as either of you, he doesn't even mind" Dolores chuckled and nonchalantly let her skimpy, stretchy thong bottoms snap back into place, essentially slingshotting you deep into her crack in a mere instant. Dolores then shuddered, the feeling was far more pleasant than she anticipated.
'Wow... I guess that's why Miriam didn't want to let him go' She thought with an amused smirk.

You only grew even more nervous when you heard Dolores' muffled response. In a way, she was right, Sheila was far worse and your mom simply kept eating foods that made her gassy as hell all the time while Dolores only did so occasionally. But this was one of those times, on top of that you were shrunken down to an extremely small size and you just got plunged into the depths of her huge ass.

On the other hand, she failed to realize that even if they weren't as legendarily bad as Sheila's or as frequent as your mom's, her farts were pretty huge in their own right, being able to rumble her equally huge butt as they blasted their way out, and you knew this better than most since she's ended up inadvertently letting those out in your face or near you. Just as with your mom, you always downplayed it to spare her feelings but it looks like all those considerations are coming back to bite you.

Dolores then clenched her prodigious plus-sized cheeks a few times to get a better feel of your diminutive body entombed by her overabundant squishy flesh, also quite warm and a tad sweaty. Once again she figure you didn't mind either as your mom was also slightly sweaty and out in the sun while she had you on her. She was surprised by how much she could actually feel you, either her crack was really that sensitive or the shrinking Zuleima did changed something with your body but in any case, she wasn't complaining, instead savoring the pleasant feeling, giving her enormous hips a shake to send her big ass into another wobbling frenzy and those undulating motions only served to pull you even deeper between her cheeks.

You knew that things wouldn't be the same as when you were in your mom's crack, but how utterly different they'd be, that was well beyond any anticipation you may have had. Dolores' ass was simply gigantic in comparison and the massive weight that pressed you from both sides went several leagues beyond-mind boggling, but these same blubbery walls were also far squishier than what you deal with before, feeling even more so like warm pudding, as if you were swimming in the bottom of an entire ocean of it, complete with the gargantuan pressure that pinned you and practically held you firmly in place.

The warmth was also far more intense, specially as the 'walls' began shaking from side to side and the fatty waves of gelatinous flesh bounced you in between. At first you didn't realize it but these motions were dragging you even deeper into Dolores' titanic crack. It was the understatement of the century but you were very much at her complete mercy at this point, and all you could hope for was to actually make it out of here in one piece...

What happens next?
