After a few minutes of just doing this passed, Brianna unmatched her lips from Jeff's well sucked tit and looked up at him. "Hey, mind if we still have some fun still? I won't change your dick though, unless you want me to."
Jeff thought for a moment, then nodded his approval to her request. Brianna grins and climbs off of him, then goes over to make the changes that she had just thought of a minute ago. And while keeping the surprise away from him, Brianna types in her changes and quickly saves them. She then returned to Jeff with an excited look in her eyes.
As she crawled back on top of him, she giggled looking down at the pile of tit flesh that from her view, looked as if it were pinning Jeff down to his bed. She had not set a hard limit to their size, and just used the "large but not abnormally massive" setting instead when she gave him his growing breasts. But from the looks of it, Jeff had to at least be an H-cup by now, if not larger. And if that wasn't enough, they were still gaining in size.
Brianna slowly and gently began to knead the pair of squishy boobs in front of her. They were perfect in all the right ways. Not too firm, but not sagging or overly squishy either. And with just enough give to sink her fingers into them without hurting him.
While Brianna continued playing with Jeff's breasts, he was wondering what exactly she did to him. It was then that he felt something different than what he has been feeling for the last few minutes.
It began right when Brianna pressed her fingers into his nipples. He expected a stream of milk to spray out, but instead, felt her fingers curl around a lip and press further into his tits. Her middle fingers slowly sank deeper and deeper into his nipples. And while he had no ideas as to how they were exactly doing so, it felt really good, and he just assumed Brianna had something to do with it.
Soon enough, Brianna switched to using both her middle and ring fingers to rub the insides of his apparent nipple holes. He still couldn't see exactly what was happening from his current angle, but whatever it was, it felt amazing. Even better than any masturbating he has done with his dick/boobdick.
He also could feel her stretching the new holes out wide, and especially long, forming them into a pair of vertical running crevices. To add to it even more, he could tell that they were becoming quite wet on the inside too. It was as if she was creating a pair of bowls for his breastmilk to pool into or something.
Brianna lowered her mouth over one of his new holes and slid her entire tongue down into it. She licked it all over, then pressed her teeth up against the tip of what felt like the tip of his nipple, only it was way more sensitive. She gently closed her lips around his nub and flicked it around with her tongue. With her other hand, she began rubbing the nub on his other boob in between two of her fingers. He felt so good that he was going to cum any second.
And so, when Brianna gave him that last push over the edge, he came. But not with his dick... each breast felt the orgasm, and a clear fluid squirted out of each hole. His nipples were so sensitive now that he was immediately right there at the edge again as Brianna didn't slow down whatsoever. She just continued licking and toying around with his breast holes.
It was then that he noticed something about her as well. Her own nipples had receded into themselves, becoming inverted. Jeff reached a hand up and pressed his thumb against one of them, the skin peeled away revealing the greatly swollen, red tinted head of her left nipple. Brianna looked at him nervously and lifted her head off of his boob.
"Hold on, now before you get too far, I want you to know that we don't have to do anything further if you are not comfortable yet with doing so. But if you are, then... well, you will know what I mean when you see them."
Brianna sat back up and stopped suppressing her own arousal which she had been bairly managing to do all this time. So the moment she let herself go, her nipples pushed out from their recesses. To Jeff's shock, Brianna's nipples were over an inch thick and had quite the familiar shape too. They continued pushing outwards, and gradually began curling upwards towards her chin after reaching over 3 inches long.
Her nipples continued lengthing until the reached about 8 inches long. Then to Jeff's further surprise, a pair of lumps formed at each nipple's lower base. Jeff watched as one by one, each of her 4 lumps swelled up to the size of a small chicken egg and was pushed out of her boob, falling down into a pocket of loose skin hanging beneath each nipple. The excess skin must have come from the tip of each nipple as now they had a flaired red cap. Jeff knew what shape they had taken, but was speechless at the sight of it.
"Well... um..." nervously stammered Brianna. "Do you think they are too big? I mean, I think you should be deep enough by now to fit them inside, if you wanted to try..."
"Inside??" Inside me?" Questioned Jeff.
Brianna nodded, "mm-hmm. Your pussies should be a perfect fit for them. Though maybe not while you are on your back, as that kind of flattens your tits out a bit more than if they were just hanging. Or better yet, if you were the one on top of me, then they surely would fit all the way inside without a problem."
"Wait a second, my pussies?"
Brianna stared down at Jeff in disbelief. "What? Your kidding me, right? How haven't you realize it yet? You have a pussy right beneath each of your nipples right now. And I turned your nipples into the clits of your pussies. How could you manage to have a double orgasm and still not figure it out?"
Jeff's face lit up with the realization of what she had done to him. Then with what she had planned on doing with him next. "So... you want to fuck my pussynipples with you dicknipples?"
"...Yeah, kinda. If you are fine with it. And don't worry about getting pregnant or anything. I believe I disabled that feature. So there is no worry about me going in without protection either. And I really, really want to feel what it is like to cum inside of your huge tits. So what do you say? Actually wait, before you answer, I have another request before that. Could you also, suck on one of them? I will do the other 2 cocks in this room, but I am curious about how a blowjob feels like as well. So, before we get into having titty sex, if you are OK with that, do you think we could try doing that first?"
