Lisa is too fast, and snatches them up first

I barely began to move before Lisa bent down and grabbed my panties off the floor of the bus.

“What do you think you’re doing Erica?” She asked me.

“I was... gonna put them back on.” I said, realizing I had made a mistake. Lisa just tsk’d at me.

“I’m sorry Erica, but you didn’t keep up your part of the deal, so it looks like your forfeited the panties.” She said.

“But you said if I came I didn’t have to-“

“Nah ah ah, I said if you cum IN your panties you could keep them. The only thing you came in was Carrie’s mouth,” Lisa said. Carrie just raised her hand to her face, wiping my juices off and into her mouth.

“Yeah she did,” Carrie playfully commented.

“Actually, if anything, I think you owe Carrie now,” Lisa said.

“WHAT! Why?” I asked, worried where this was going.

“After making her drink out of that dirty pussy of yours, it’s only fair you give her something back,” Lisa responded. “And I know just what you’ll do.”
