"I particularly like those green panties you wear! I have a lovely pink pair I'd love to see you in!!! Untie me now and we'll take turns tying each other up later!!!!"
"But Batman...."
"Batman doesn't have to know...it will be our little secret!!!"
"No tricks?"
"No tricks that you won't like!!!"
"Let's go before he gets back!"
"I can't wait to see how much of a wonder you are Boy Wonder!!!"
