Grab her breasts

Although you're overwhelmed with the possibilities available to you, it's clear what you want: a titfuck from Julia's brand new breasts. They're a bit sticky at the moment, so you glance around for something to clean them up with.

"Would you mind grabbing your clothes?" you kindly request, smiling down at the kneeling blonde.

"Of course not, Jack," she affirms as she gets up off the floor and walks into the kitchen, ass swaying from side to side with every step. Even Mike, who's being kept pretty busy by his video game, glances up at his mother's behind. You see his still-exposed cock stiffen slightly before he turns back to the difficult battle that has him so absorbed.

Julia returns from the kitchen carrying high heels, a bright pink thong, and a matching strip of cloth that must be an incredibly skimpy tube top. She kneels in front of you, still holding the clothing.

"Clean yourself up with your clothes, baby," you command, trying to sound authoritative.

She chuckles slightly as she begins to wipe off the jizz, making a mess of her top. "'Baby?'" she repeats with a small laugh as she continues cleaning herself. "I've known you since you were a kid Jack."

You nod and grab her by the shoulders, pulling her closer and placing your still erect shaft between her tits. She squeezes them together with her hands and then starts to slide them up and down on your cock. Brushing her shining hair back with a flick of the head, she looks you directly in the eye, licking her lips as her heavy breasts bounce on and off your lap.

Taking a moment to look around and enjoy this heavenly scenario, you come to an odd realization: she's putting a lot of enthusiasm into this. The situation is clearly very normal for her, as she seems quite casual about what she's doing, and her son is barely taking notice at all. Still, she really seems to care about doing a good job in pleasuring you. Shouldn't she be more or less indifferent? You ponder the specifics of this new world with what little brain power you have to spare as she rubs every inch of your cock.

After several moments, you decide that there's no harm in simply asking her. "Do you enjoy serving me, or your son, or...anyone?"

She looks slightly taken aback, hesitating for a moment with her answer. "Yes, I enjoy it," she says eventually, still stroking her body up and down your shaft. "Why do you ask?"

"Well, isn't this kind of thing just...normal?" you ask. "I bet it happens all the time, and it's not like you have a choice in the matter. I'm sure most big breasted girls don't ever pay any mind to how they're used, but you're so enthusiastic about it...I was just curious as to why, I guess."

"Well, yes, a lot of women don't have much to say about how they're every man's public cumdump. That's just how the world works, there isn't much more to it," she confirms with a nod. "Just because the majority of them are like that doesn't mean I have to be, though. There's plenty of girls who like to be enthusiastic about this kind of thing. Like you said, we don't have a choice to begin with, so why not make the best of it?" she says with a soft giggle, pushing her breasts all the way down on your cock and licking some pre-cum off the tip.

Her adorably nonchalant manner, combined with her well-trained ministrations, are almost more than you can take. You let out a moan, feeling that you're about to explode. She notices and, letting your cock slip out of her mouth, redoubles her efforts. Her giant breasts massage you rapidly, and within seconds you're cumming, shooting dozens ropes of thick semen onto her smiling face.

As you lean back, completely spent, you watch as she licks your cum off her full lips. She's completely drenched with several strings of your jizz dripping off her chin and onto her new, and apparently improved, breasts. After swallowing some of your load, she looks up at you kindly, leaning back. "Oh, Jack, I almost forgot how delicious your cum tasted! It's been so long since you've given me the honor of letting me be your cumrag. You really need to stop by more often so you can fuck me more. You know I'm always happy to let you use me. Now, with that handled, how about I get you boys some lunch?"

You nod weakly as Mike gives a thumbs-up. "Sure thing, I'm almost done with this level. I'm feeling a bit stiff, though, so don't get dressed or clean up or anything," he says, reaching down and tapping his hardening member playfully against her soft lips.

"Of course not, sweetheart," she says as she smiles up at him lovingly, giving his cock a little kiss. Julia then rises to her feet, still dripping with your cum. "You boys have fun. I've got some sandwiches to make," she says as she looks over to you with a wink. "I'll bet Jack is feeling pretty hungry after giving me that much cum."
