Make it obvious ;)

I decided to make sure she sees it. Just to make her get the idea of what I want. I put the bulge in my pants on the edge of the table. Not enough for it to seem intentional , but enough for her to see it. She looks away and blushes. "are you ok Megan? Is something wrong?". "err nothing at all, hehe" . "oh my god! I'm so sorry Megan, I didnt mean for that, I mean I'm so embarrassed...." . She looks at me and ask in a almost whisper. "did I do that to you?" . "umm, yes you did" . "what was it that turned you on?" .
