Beau's thinking the same thing. Much as she wants to just tear off clothing, there is something to getting to know what exactly your partner wants. Testing the waters.

It's just that now that she's kissing Lin, she's not sure how much of that testing she can do by dipping her toes in as opposed to canonballing into the water, to extend a metaphor.

Her hands move down from Lin's face, picking at her shirt to try and tug it off, while at the same time walking them back to the gazebo. It's not privacy she wants so much as somewhere other than the ground to get Lin down to.
