She is intrigued

"Uh, I can explain," Matt said.

"Explain why my friend has cum dripped all over her face and tits while she's huddling under your desk? I'm really looking forward to hearing this one."

"Come on, Karen," Amy said. "I told you I was going to get him. Don't pretend like you're all surprised."

Karen laughed. "Sorry Matt. I couldn't help from jerking your chain. And speaking of jerking..." she stared pointedly at his still hard dick... "you'd better put that thing away before it gets you into more trouble."

"Uh, yeah." He fumbled with his cock... which, because of its stiffness, wasn't in a hurry to go back into his jeans.

{if ****=true}"Oh, hell. Let me help you with that." Karen grabbed his dick{if Karen>69}, gave it a quick lick to clean it off,{endif} then pushed it back into his boxers. "I can't believe my brother has become some sort of campus hottie."

"I can't believe you did that to your brother." Amy seemed both shocked and, to Matt's delight, excited by what Karen had done.

{if Karen>69}"If you think I'm going to let any of those jerks at school introduce me to sex, you're crazy," Karen fired back.

"Yeah, I get that."{endif}{endif}

"Now," Matt said, "Did you really have trig problems, or should we get ready for tonight's dance?"
