The Science Department

Now they left the building and went to another one. Vanessa announced "this is the science department building. As you can see it's all state of the art and it has many new things." She took them to one of the rooms, "and this is one of the Chemistry classrooms," she said. Mikayla thought she had seen similar in the other colleges but at least it was colorful and well organized, she hoped this meant this was going to be fast, and she was right but what was going to be fast was going to be something else. Vanessa continued, "this room and this whole building has a top notch vacuuming system. The President of the College has been trying to install it in every department, but we're not there yet, almost though. It activates by pressing that button," she said pointing toward a button placed by the light switch on the door. "But don't push it. The system shouldn't be turned on until there are no people in the room, that's why always the last person closing the door for the day activates it before leaving, and why the maintenance people at least have less cleaning to do and can take care of more matters throughout the college."

Jason took note of that, he wasn't sure why people couldn't be here when the vacuums were on, but at the very least they could scare Mikayla he thought. Jason had just turned 18 this year and was going to start his senior year in high school soon, but was way more immature than his sister who was 18, but was about to turn 19 soon when the school year ends and she graduates; their birthday wasn't apart by much and their age was about 1 year away from each other, but Jason still loved to prank Mikayla and her recent misfortune had turned on his mischievous streak. Since he was the closest to the door, while everyone was distracted hearing what Vanessa was explaining he pushed the button to turn the vacuums then ran towards his sister that was in front and pushed her down. The vacuums came out, they looked like roombas so he didn't know why even the precautions, but at the same time Vanessa screamed "who turned the vacuums on, we have to run away," and started trying to run away but things had happened extremely fast. Mikayla was keeping an eye on Jason every now and then because she knew he was going to try doing something, when she fell, she thought "well two can play at that game," and gave him a low sweep making him tumble and fall. Then she was getting up and Jason tried to do that too, but trying to grab footing he pulled his sister's panties down and she tripped and that made her legs to actually push his shorts and underwear down too. The other people behind just started running then, but with both siblings blocking the path by tripping and falling constantly they couldn't move past fast.

The reason for the precautions is the vacuums' suction is quite ****, it instantly started pulling the group back, especially since there were several of them. Everyone lost their bottoms, quite easy for the bickering siblings since they had those garments half off already, and for Vanessa who was wearing quite a short skirt it was taken with her panties. The vacuums didn't stop though, everyone was almost getting choked by being pulled from their shirts except for Mikayla because she didn't have one on, and they had to take them off fast to keep them from pulling too hard on their necks. Just then they finally started running out but the vacuums had the last laugh, for they manage to just then break the safety on the women's bras and pull them off of them. Jason was slack jawed, he had seen his sister had big breasts when she came out on only undies, but what he saw blew him out of the water. He saw when the vacuums took the bras off and saw Vanessa's breasts basically spilling out of the bra like jelly out of a donut; she had breasts that were twice those of his sister or who knows how much bigger than hers, no one would have known while seeing her clothed. They managed to get out and close the door behind them, but all they had to their name was a walkie talkie that Vanessa managed to keep by holding it on one hand, and the clipboard with bullets of a schedule plan on the other.
