Pick a pretty woman off the street.

It's not hard to pick out various people, taking a small walk (like three steps for you now) you come to a busy spot where people tend to hang out. There's plenty of people to choose from, and most seem to be ok with you here. Combing through with your eyes you then see her, a beautiful woman that makes your hard on pulse just by looking at her. You snatch her up and take a closer look. You don't know her, at least if you've ever met her it wasn't for long. She has big tits, they wrap around your thumb a little, probably E cups or F cups. Her ass is large, bigger than most women, but definitely not as big as some women out there. A great find for a quick glance, but as you pick her up and look at her she says "Umm can I help you? You know this is kind of rude, just picking me up." She looks so cute being annoyed, a very pale skin yet fair and clear.

"I really need release and you're the first pretty face I saw, so if you don't mind..." The girl looks shocked and says "B-but it's so big, literally as big as my house. You can't do that please." She looks so cute while she begs, you realize you started one handedly started jerking yourself off. You know something she doesn't about the changes you made, she and anyone else out there can stretch as much as you want. So as her pleading requests turn more towards the side of terror you shush her and say "Come now it's ok, you can take it. Just watch." You then bring your dick up and start trying to decide what hole to use.

You should probably go for some foreplay, so her mouth will be a good start. So with that in mind you aim her face first towards your dick, with no luck since she still seems to be resisting. "Just open your mouth, or should I just go straight for your pussy?" She gives no response and doesn't open her mouth so you turn her over again. With your massive tool now between her legs you wink at her and start pushing her onto your dick. The effects of her stretching are near immediate, from the look on her face she seems to have a little bit of pain as your dick tears through her leggings and underwear and start to stretch her. Then her pain turns to discomfort as you reach the end of the head of the dick, to rub it in you say "See? I told you that you could do it, now this little bit is nowhere near the end of my dick and you are definitely taking it all, maybe multiple times."

Before going to town on this poor girl you find the pearl. You don't need people attacking it right now so you give one change, your sperm is special in more ways than one, but right now the most prominent affect is it will make people sexier the more their bodies take in or get coated by it. Your balls gurgle as sperm production has just been changed and then you crush the pearl setting this as a default, you'll test later to see if you've gained the power or not. "Ok now I'm ready." You say as you pull on her body. You feel the barrier of her cervix for less than a half second and know you are easily going to stretch all parts of this woman. As her body stretches around your massive cock you fixate on how her boobs lay on either side of your cock, though they too are stretched thin to wrap around your massive tool. The bulge in her is more than just an outline as you would assume, it's like you are putting on a condom but you are the one with the dick and the condom is made out of vaginal flesh.

The girl has started moaning, though very incoherently. As you pull her by her legs and hips you get close to your base, and start rocking your hips to try to push in and out of her. She is so tight around you, but if you stay that size every woman or man might be this tight with their first time with you. As you bottom out you use one hand to move her up and down on your rod while you still buck your hips, the other hand goes to your breasts. Your breasts are a bit sensitive but mostly due to arousal, it feels nice kneading the flesh and pinching a nipple from time to time. While you fuck this girl you see her face get a more focused look and her breathing quickens then she moans loudly in a scream, all of a sudden all around your cock gets tight and it feels like it's sucking you. She's orgasming and it feels wonderful, if she can keep her muscles going like this you'll cum soon.

The girls orgasm lasts longer than normal, partially due to your sheer size and partially due to you still ramming it inside her. Now as you pick up pace and your pre is sloppily sliding all over your cock and inside and out of her pussy, she's starting to get a small bubble forming from it. Small is a relative term, it's probably the size of a basketball, but you're close to the real climax and you'll see how big she will really get. Your balls have really been churning lately and you need to release. You slam her harder on your dick, and faster too. The tits and bubble of cum jiggle and stretch repeatedly as you go in and out of her. As you get close you feel her get tight again from climaxing again, and it's that little bit that pushes you over the edge. You cum and the first spurt is way more than any normal person can make in a month. You cum for minutes on end, and she balloons out with her gut hanging like a water balloon around herself and your meat. As your orgasm fades a bit you watch her body begins the changes you made with your cum. From under her belly you see her tits engorge and grow to a size she probably won't be able to walk with. They reach down to her crotch but are also extremely fat and perky. Her ass grows too and her hips get wider making her almost look like a tiny woman built for your size.

Watching all this keeps you hard, but the immediate need to fuck is gone. You can choose to leave, or at least find a new fuck, or you could choose to fuck this girl more. The thought crosses your mind you could probably wear her while you do other things or you could go all the way through without breaking her if you used her ass or mouth. You also should check if you gained the pearls powers. So many options, what will you do?
