The vial.

"Hurry up! My excuse of lady problems will only last so long." She wants you to pick quickly, but she's making you choose who to potentially get pregnant by. You eventually decide on the option that doesn't involve you fucking 42 kids. Still buck naked you stand up and reach for the vial. She gives it to you and you reach down to slide it in. It feels really weird goin in, it's cold, so it makes you shiver, but it's also very wide, making you worried tha you are going to break it right away. "You get three mistakes" Abby says to you. "It takes three, and only three, hits before it breaks." As she talks she presses a button on a remote and four small arms shoot out inside you, locking the vial inside your virgin pussy. She walks out without another word leaving you to get partially dressed and go to class.You start to bend at the waist to pick up your skirt and shirt, but remember the vial and crouch instead. As you head to the door you are hit by a brilliant Idea; people leave their lockers open all the time, you could steal panties and maybe even a bra. The problem was that girls at your school aren't very forgiving, so they would fuck you up if they found out.
