Breakfast Fun

All attempts to somehow conceal those rock hard 10 inch of meat fail spectacularly, which leaves only one option: wear it proudly. The bouncing of so much cock with every step feels new yet exciting, and the tent it causes to not only your pants but also your shirt is hard to miss, but she asked for it, so there it is. When you enter the kitchen that not only earns you a naughty smile, but also a gentle kiss from a girl that is noticeably horny at this point.
"Damn, you prepared for real..." you can't help but to notice the rich options on the kitchen table "Where did you get all this?"
"We had some stuff left in the fridge." Sophie responds with a smirk and takes her side on the table.

Breakfast goes as usual, mostly, there is this boner getting in the way of things occasionally, and every time it does Sophie somehow seems to get a little hornier. Other than that though the chat goes pretty casual. Obviously she is more hungry for food at the moment than for sex, something that changes rather quickly once she had her food. Her talking turns to silence, yet her body language speaks more than enough. You can see her hardened nipples poking into the oversized t-shirt, and eventually she approaches you. Gently she runs her hand over your chest, then down to your still relentlessly throbbing erection. You perfectly know what she wants, but she shall get it her way, so you play along. She looses her clothes and eventually climbs onto your lap and started to kiss you sensually and needy. Her greedy hands unpack that monster of a dick from your pants, till it stands there unobstructed to enter her. Her unhinged moan of relief when your dick finally slides into her would have been enough to get that cock back up again if it hadn't already been turned into a permanent bar of steel. And as she slowly begins to ride you, you finally can enjoy the new size of her boobs, gently moving over your face. An invitation you can hardly pass on, so you sink your face deep into her now vast cleavage. With your two orgasms this morning it ain't hard to keep yourself away from the edge, but that girl is boiling and steaming with lust. Moaning and panting she ravages your increased size, edging with her eyes rolling back, till eventually she whispers:
"I want you to cum with me when I do."
"I am... kinda spent." you try to explain without ruining the situation, but suddenly with yet another almost maniac grin on her face forming you feel a tingle downstairs in your balls. You have no way of checking at this moment, but when she allows herself over the edge a few seconds later, not only does a sudden orgasm out of nowhere eradicate all thoughts, but also you realize that your equipment ain't spent at all, very far from it actually. Under loud groans you blast such a volume of cum into her that you turn the phrase 'filling her up' into a literal thing.
"FUUUUUUU.....CK!" you yell as that dick keeps shooting one big load after another, till eventually, after what felt like an eternity, you collapse in the chair.

Her unmounting your cock was everything but pretty. A large glob of juice followed from her womb splashing not only on her thighs, but also your groin. And when you finally get to see your new balls you suddenly know where it all came from.
"What the hell?!" you exclaim as you look at those orbs between your legs, each easily the size of a softball.
"I might have gotten a little carried away..." Sophie giggles, and with a gesture all that cum disappears. You stand up and feel those massive testicles press against your legs, looking almost comical on you, if your dick hadn't been upped in size substantially. Yet even with 10 inches those new assets look a bit out of place.
"Am I going to stay like that also?" you wonder, bringing the fact that your girlfriend somehow seems to change your body at her whim back to your presence. Sophie ponders for a moment, then she makes an offer.
"Let's both change each other into whatever fantasy we have at the moment, and we turn back on Monday, ok?" An offer right out of the mouth of the sexiest devil you know.
"I am not sure..." you hesitate. You know some of her fantasies, and those are already pretty crazy, and with the sudden threat of them becoming real, you feel a little overtaken.
"Ok, I start." she smirks. "Since I know you like big boobs, I will turn these..." she gestures at her rack "... into exactly the size of your wettest dreams, ok?"
"I am not sure..." you stammer, both of what size you'd want, and also if that would anger her. "I love you the way you are." you quickly add just in case.
"I know, dummy, but I am sure you love me more often if I look like this..." she dramatically snaps her fingers, and suddenly her tits start to expand rapidly. Before your eyes her boobs swell through the entire alphabet of cup sizes, till she ends up with knockers bigger than her head, perfectly shaped, and crowned with beckoning nipples.

"Wow." she laughs "Didn't knew you like em this big..." Her hands probe the gigantic tits that now hover in front of her, ignoring gravity in their perfect shape.
"I... I can explain!" you stammer, but before you truly can she shoves your head right into her new cleavage.
"Sshhh...." she gently squeezes your head with her mountains of tit-flesh "This weekend we don't explain, this weekend we have fun, ok?" And who are you to disagree with your seemingly omnipotent and very kinky girlfriend.
