Extend the Story - Add a Room

This is you're time to move, you think, as you sneak an arm around her waist, as she snuggles in a bit closer you bring you're arm down and lift her chin up so she's looking at you, and then you're kissing her, slowly then faster and soon she's kissing back hard.

Encouraged by her behaviour you slide you're arm down her arm , slowly down her sides, making sure to cup her left breast firmly, making her moan softly.

Suddenly, she's backing away her soft brown hair a little dishevelled and her lips red.
"Oh my we need to stop! It's a movie theatre."

You're a little annoyed that she stopped you.. But she is being logical.

What do you do?

Be a gentlemen and wait.. Maybe later?
