Smooth Operator/Gabby's Party/Tara/Kiss her
You take your little sister by the shoulders and then crouch down and quickly thrust your elongated K9 nose forward and quickly lick the lower front portion of her muzzle, causing her to immediately cut off what she was saying. She looks back at you, her face a mixture of shock and confusion that you would have just done such a thing. With her stunned, you gently bring your muzzle into hers again, this time gently resting nose-to-nose against the tip of her muzzle to the point where you can feel her breath going into your mouth.
You allow your tongue to dart out of your mouth once again, this time managing to get your tongue to go inside her thin K9 lips as you lick her teeth. You continue to lick her lips, now starting to go down the sides of her muzzle to continue tracing the line of her lips in this most intimate gesture between two wolves that you are sharing with your own little sister.
As you continue to give your wolf-style kiss to your little sister, she timidly and expiramentally sticks out her own tongue, lifting up the front of your upper lip on one side with her tongue as she begins to return your kiss. It is a little hesitant by comparison and she only licks once or twice by comparison to the continuous licking of your kiss as you go up and down licking every inch of her lips along her muzzle and even nuzzling her cheeks with your damp nose when you reach the end. However, as tepid as her return kiss was, it's clear enough she's responding to your gesture of intimacy and affection.
