I should keep it subtle...

"You know," Just one button and... "It is a little warm in here..." How's that look... Wow, that's way more cleavage than one button should give... I guess this top is a little tight, I mean, even just judging by the way my nipples are poking through, but still...

"Ya?" Was that a nervous swallow? How cute! "You want to, uh, move somewhere cooler?"

"Nah, if I get too warm, I can always just loosen my top a little more." Hehe, now he's all flushed! This is fun!
