Kara stands up and makes a private show for you of taking off her panties:
"I can see that I'm going to have to take these panties off to compete with those massive implants!" she giggles, "Wow, I didn't know they came in that size!"
You nod and smile at this.
Kara sits down again next to you and rests her hand in your crotch, her hand perfectly poised to feel every throb and twitch as you get more and more turned on.
