The seat next to Jenna

Jenna was Megan's best friend. She was a short blonde girl with smaller tits than Megan but she made up for it with her amazing ass. Today she was wearing a plaid skirt and a black tank top. She had her hand on the inside of her thigh, just below the bottom of her skirt as Megan took her seat next to her. Jenna looked Megan up and down. "Are you okay Jenna?" Megan asked.
"W-what? Yeah I'm fine. I like your outfit, if it new?"
"No, it's just a plain t-shirt and jeans Jenna. Are you sure you're ok?"
"Yeah I'm fine" Jenna laughed as she put her hand on Megan's thigh and gave it a little squeeze. Megan didn't think too much of this, Jenna was always very tactile, but then her hand slid upwards. "What are you wearing under your jeans?" Jenna asked as she reached for Megan's button.
"What the hell are you doing Jenna?" Megan said as she slapped Jenna's hand away.
"I just want to see your panties..." Jenna reached for Megan's button again as the bus pulled up to the school. This time she managed to get it loose. Megan stood up and tried to get off the bus, away from her friend. It was too late, Jenna had unbuttoned her jeans and gotten hold of them, pulling them down as she stood up. Megan was shocked as she stood in the middle of the bus in her black thong. Peter, who was in the seats across the aisle made a strange noise as he attempted to cover his crotch. Several people wolf whistled and shouted inappropriate comments, including Jenna who shouted, "Take the rest off, sexy!" she then leaned over and slapped her thong-clad ass. Megan noticed some of the guys from the back of the bus moving towards her, all of them with large bulges in theer pants. "What's gotten into everyone?" Megan thought.
