Working it out

Looking at the girl in front of you, there was no way you could resist her if she really tried. You weren't certain that you really wanted to resist anyway. You were starting to fall for your sister, and the last part of your mind holding back needed to feel like you had done everything you could to convince her that this was a terrible idea.

"Anna," You check her eyes to make sure she is listening to your every word, "We can't do this. We're blood related sisters."

"But we already have," She watches a dog walker pass by before continuing, "It's a lot harder to unfuck something, and I don't see us magically escaping this," You sigh, and wrap her in a bone crushing hug.

"I don't want to hurt you," You guessed that by this point she had realized you were trying to convince yourself as much as you were trying to convince her.

"You won't," she squeaks out from between your breasts, before wrapping her own arms around you, "I trust you, Jane."

"My heart's not ready to be in a relationship."

"And neither one of us is anywhere near ready to have a kid," she replies.

"Fine," You release her from the hug, and she reluctantly separates from you. Deciding to finally double down on every mistake you've made in the last day, you lean down, your face slowly approaching hers. You rest your forehead on hers, and simply stare into her eyes for a minute. Anna makes the next move, connecting you by lips for the second time today. You stay lip to lip for a couple seconds before she hesitantly parts hers, and starts poking you with her tongue. It takes another couple seconds before your brain puts two and two together and you open your lips to join her. Your kiss is sloppy, terrible, and all around, a complete disaster. Neither one of you has any real experience kissing, and now that you aren't swimming in post-climax bliss, it shows. Anna pulls away giggling, and you have to fight back your embarrassment.

"We're going to need some practice with that," She comments to no one in particular. You sigh, and slouch on the bench in response.

"Well, since you're not going on that date anymore, how about I take you out tonight?"

Anna produces a beaming smile that could blind the sightless, grabs your hand, and drags you back to the car. You assume she's already brimming with ideas, and her enthusiasm was beginning to break through your cold shell.
