Give the girls a wet surprise
From Create Your Own Story
You fish out your semi hard cock and begin rubbing it to full mast. Soon enough, it beings to pulsate in your hand as you furiously masturbate. A few minutes later, your dick begins to throb and your balls tighten. You blast thick shots of sperm into the receptacle. After your 5th shot, the receiver is filled to the brim and begins to ooze cum down its sides. The machine slowly begins to churn, swallowing all the semen into it. The needle gradually swings all the way to the right, indicating it is full. With one flick of the wrist, you flip the switch for your sister's studio on.
"Aaaahhhhhhh!!!", you hear from outside the room as the girls become drenched in a cum mixed rain. You peer outside cautiously as to not get wet yourself. Most of the girls are running for shelter, although already soaked in seed. A few of the younger girls were tilting their head up and sticking out their tongues.
"This rain tastes so yummy!", they said to one another.
After 15 straight minutes or showering, each and every girl is thoroughly saturated. You can see through all of their uniforms. Your cock grows hard again from the sight of dozens of pairs of lovely breasts, dancing up and down as the girls ran. You can also see which girls shaved and which didn't. You wonder how many girls would get pregnant from this? You giggle to yourself and skip back to where you said you would meet your mother after practice was over.
"There you are sweety!" Your mother says as you appear from the crowd. Your sister appears shortly after, a little bit crusty from the cum drying on her uniform.
Together, you drive home and begin to get ready for bed after a long day. Your mother locks the door behind her after she enters her room. Rachel is in kitchen making herself a protein shake and about to take a shower to wash the sweat and cum off her body.
