Start with a haircut and some clothes.

After parting your long hair again, you notice you're in the parking lot of a barber shop. Looking over towards Alex you say, "Hey, buy me a haircut. It's hard to see with this hair in the way. Be good and maybe we can work something out later..."

"C'mon, John. Do we have to?" Alex whines.
Ignoring him, you start walking towards the barber shop after checking your shorts to make sure nothing is visibly leaking out. There's a dark stain where the shorts are soggy, but it's so hard to see with you hair like this. You try walking in a way to keep your legs together then to hide the stain, which involves you swaying your hips in a feminine manner.

Without looking at Alex you say, "Also, don't call me John while we're out in public. It's suspicious. At least try to make it sound a little more girly, like... Jane, Ok?"
Alex shrugs as he follows you into the shop with a sigh, staring at your bubble butt as it sways side to side, and says, "Sure thing, Jane..."

A few minutes later you're seated in the barber's chair and tell the man to cut your hair shorter. He shows you some sample pictures and points one out that would suit your face best. Before long, you have your hair cropped down into a cute pixie cut. Looking in the mirror, you're surprised how much cuter and sexy you look with short hair. It goes well with your short frame. Not to mention, you can clearly see again. Alex pays for your haircut, surprised at how good it look, and then you're off across the street at a store that sells clothes for yoga.

Looking around, you find some tight blue spandex shorts that would look cute on you. They're very short so they'll show off most of your pale supple thighs. You also grab a sky-blue sports bra, some socks, and workout shoes before heading off to the changing room to get out of your dirty clothes.

Alex follows you along, groaning at the price of the clothing, but every time you walk away he stops to stare at your hypnotic ass. When you open the door to the changing room he tries to step in with you but you hold up your hand.

"Um, Alex? Would you mind if I changed in peace for a moment?" You ask nicely, since he's buying you the clothes.
"Oh come on, uh...Jane." Alex whispers quietly in the store, "We've already fucked. I'm going to see everything in there again later..."
You sigh and shoot him a look, hold your new clothes up in front of you like a barrier between him and your sexy teenaged body. You whisper back, "not with that attitude, Alex. I still have to fix your car then head home and figure out what's going on. So behave for a moment, and then we can work something out..."

Leaving him with that, you step into the changing room and undress. There's a wet splorch as you pull down your shorts, along with a slimy trail of cum connecting the crotch of the fabric to your smooth, perfect pussy. You pull off your top next after kicking the shorts away and you're now completely nude.

Looking at yourself in the mirror again, you're in awe at how cute and beautiful your face is, with your bright blue eyes and your short blonde hair. Your body is also excellent, and healthy looking. Not too athletic, not too much fat, a perfect balance. Your hips have a perfect bell shape to them, it's distracting even. No wonder Alex and that security chump wanted to fuck you raw. Your skin is smooth, clear, and fair. And then you look at your crotch again, as another thick yellowish glob of spunk drips out from between your pussy lips and falls onto your inner thigh.

You sigh while looking at it. That old, black, toad-faced security guard at the mall really ejaculated a lot of spunk inside you. It's been almost a couple hours and a little more just slid out. You rub your lower belly, slightly worried. If you recall correctly, a woman's cervix instinctively laps up the cum in her pussy, filling the uterus with semen. You have no control over a bodily function like that.
Maybe his jizz is too thick to work though? You can't recall if semen was more or less potent if it was jelly-like like this stuff is. You curiously poke the glob on your thigh when Alex knocks on the door and says, "hey, hurry up in there. Unless you need my help getting dressed hmm?"

You quickly respond, "uh, sorry, I'll be done in a moment," before picking up your new sporty clothes. You look back down to the semen on your thigh and wonder for a moment if there might be more still inside you.

Double checking and cleaning out any more cum would certainly make you aware if you're at risk of getting pregnant. But Alex is getting impatient and you need him to not cause trouble. If you want to hurry up and get dressed then you can brush your worries aside. Surely that security guard was too old and busted to be able to get teenaged white girls pregnant.
