Jack wasn't speechless often, but it took him a moment to process everything the young woman has just said. Then he took another moment to figure out how to best respond.
"Layla? Please, stop apologizing. C'mon, sit down next to me." He slid his arm around her shoulder, so he was hugging her sideways, as he continued. "I'm... glad that you like me, 'cause if you didn't, it's make what Lucas was talking to me about pretty impossible." He hoped he was reassuring her. "I like you, too, so it all works out. I... I wouldn't feel like a prop. I've... agreed to do this... event because I like you guys and I... want to help you out with your fantasy. I've..."
How do I put this?
"I've been a part of a threesome a few times in my life, though the most recent one wasn't... just a one-time thing. I'm fine with that, okay? I'm... intrigued that you'd want Lucas more involved, since he didn't seem inclined when we were talking about it."
Jack pushed a lock of her hair behind one of her ears and smiled. "You're not a 'silly kid', and you smell good, too."
