Jon tried focus more on hearing what the two teens were saying.
"I found this today, and it made me think of you." Biff said.
"What is it?" a feminine voice, presumably Sarah asked.
"It's a beautiful stone, though it's beauty pales in comparison to yours."
'Since when had Biff been so gifted with words?' Jon wondered.
"You've been working on that line all day haven't you?" Sarah asked, amusement evident in her voice.
"I have. Did you like it?" Biff asked with what may have been an edge of desperation in his voice.
"I suppose it will have to do. But don't think you're getting into my pants with lame lines like that."
"What? Come on Sarah. You still gonna hold out on me? We've been going out for six months and I haven't even gotten to second base yet." Biff whined.
"Second base? Is that all I am to you?" Sarah started to sound annoyed.
"No that's not what I mean. I mean I love you, you know? And I was just hoping to explore that love... physically."
"Oh really? So if I were to do... this." she said beginning to rub Jon and Karyn and Biff's cock. "What would you do for me?"
Jon was starting to get pretty excited now, he had apparently picked the perfect time turn himself and Karyn into balls: it seemed like they might be going to experience sex like nobody else ever before.
