Dinah looked entirely too young when she had that look, the one that said 'just kiss already' on her face.
Fortunately, Barbara thought the kissing was actually warranted this time, and reached up, grabbing Helena's neck and reeling her in.
Helena smirked into the kiss for a moment, before nipping at Barbara's lips, trying to take control. After a long moment, she had to concede; Barbara's experience had her fully on top there.
As they parted, both women looked satisfied and ready for more.
"Now, this is a partnership worth keeping forever," Helena said, making Barbara grin and Dinah cheer.
