Delayed reaction

Alex headed off down the hall towards second hour English IV. Chelsea was in front of him, and one of her friends walked up to her. "What's that on your cheek?" her friend asked. "Looks like cum."

Chelsea reached a hand up to her cheek and felt the sticky substance. She pulled it away from her face and looked at her fingers. "Oh my god, IS that cum?" she asked. "What the hell? She smelled it and looked around. She looked right through Alex as if he did not exist then ran off towards the restroom.

Alex thought for a moment. It took about a minute for Chelsea to notice something was amiss. He walked on towards Ms. Rogers's room. Ms. Rogers was a 40 year old MILF, divorced with two kids. She had a few extra pounds, but it made her curvy and gave her a spankable butt Alex had fantasized about spanking before taking her doggie style over her desk. She had thick, auburn hair that she usually pinned up. Today she was wearing black slacks and a long sleeve white blouse. Her hair was pinned up in a messy bun with lots of bobby pins. She stood outsider her classroom and greeted students as they entered.

Alex did an experiment. He looked at his watch then started pulling bobby pins from Ms. Rogers's hair. Her hair fell down around her face and shoulder, but she nor anyone else noticed. After having pulled about half the pins free and leaving her hair in disarray, Alex then undid her fly and pulled it wide open, so her bright pink panties were on display. He then reached around her and gave her a massive wedgie. which left her panties sticking up over the waistband of her slacks. Ms. Rogers seemed oblivious to all of this as did her students. When he was finished, Alex checked his watch again. It was 8:59. The bell rang, and he entered the classroom just before Ms. Rogers closed the door and walked to her podium to take roll.

Ms. Rogers began to take roll and about half way down the class list, reached up and felt her hair. She realized it was hanging loose all over. She had a confused look on her face and seemed not to know what to do. Stop class and fix her hair or continue. She then started shifting from one foot to the other as she apparently felt her panties wedged deep into her crack.

Alex looked at his watch. It took 90 seconds from the time he stopped. He figured that as long as he was messing with someone, she did not notice anything or thought it was normal, but 90 seconds after he stopped, she noticed what had happened, but still could not see Alex or know he was the one behind it. Or maybe it was 90 seconds after her moved away from the subject. More tests were needed.

Ms. Rogers finished taking roll and told the class to start reading in their texts. She walked over to her desk and fetched a mirror from her purse. She had her back turned to the students, and they all saw her panties sticking up. Most students snickered, but Mandy Teller, the class prude, squealer, apple polisher, and stick in the mud got up and walked over to Ms Rogers. She whispered something in Ms. Rogers's ear.

Ms. Rogers reached behind her and felt her panties sticking out. She blushed deeply and told the class she'd be right back. She then left.

Alex studied Mandy. She was cute in a girl next door kind of way. She had shoulder length strawberry blonde hair, blue eyes, and few freckles. She wore a floral, sleeveless dress that came down to her knees. Alex wondered how he'd fuck with her.
