As soon as Jack connected to Katie's mind, she blasted him with a question.
"Holy shit, Jack! What was that?"
Before he could respond, she added, "Whatever you did, it made Madison and I cum so hard we couldn't stand. For a moment I thought I was having a seizure!"
"Sorry. I had no idea it would affect you two."
"What did you do? Madison and I can feel it when you have sex with us, and it's nice, pleasant. But this? This was intense."
"Wait. Are you saying that what you sense when I have sex with Madison is different than what you sense when I have sex with any of the other girls?"
"Yes! When you have sex with anyone else, I can tell that you're having sex, and can sense your pleasure, but with Madison, it's like I get echoes of her orgasms and yours. It's enough that I can give myself an orgasm with a light touch, or I can just bask in it. It's nice."
"Do the other girls know about this?"
