First, get some answers about why she held out

It occurs to you that you can finally get the answers you've wanted from her. "Tell me, and be honest with every question I ask you, how come you never let me go farther than this before?"

Your ex runs her hands through her hair, a motion you remember her doing many times when she was embarrassed. "I wanted to, but I didn't want to disappoint my parents. I was afraid they would find out if I did anything."

"So that's why you dumped me for Leo?" you ask. "Because the religious guy wouldn't pressure you for sex?"

"Yes. At least, that's what I thought would happen."

"What do you mean?"

She blushes. "I'm sleeping with him."

"No way!" You grit your teeth, holding back your anger. You put all that time into her and Leo the muscle bound jock gets to fuck her!

She fidgets in the way she always does when she's trying to get out of something. Except this time, the fidgeting makes her open blouse flutter, drawing your attention to her great breasts and making it harder to think. "He asked on our second date and I was just tired of waiting."

So Leo didn't even put out all that much effort? Good thing you made him expose himself in public. The only question now is, what do you do with her?
