As Lisa's chest was still heaving up and down, she'd occasionally shake all over from her intense orgasm though she looked like she needed a short break from the looks of it. Not only was she covered in sweat and our juices, but she also looked like she had already lost feeling in her legs, and to our surprise, the plug she was wearing was a few feet across the floor—and it was due to her pushing too much that made it fly out.
Kaley wore as smirk as Lisa shrunk down from embarrassment:
"Look at what we have here~"
"Ah— D-Don't— Hngnhh… D-Don't l-look, a-ah!"
"Tell us, you're the one always on the receiving end when you're with your sister, huh?"
"Wha— N-Not always but… y-you know… I just p-prefer it t-that way s-sometimes… B-But how did you know?"
"I mean… With your ass taking that plug and you having no gag reflex means that she's training you real hard for the real thing."
